Surgical Approaches to the Respiratory System: Nasal and Laryngeal

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-11

Key Takeaways

• Nasal and laryngeal surgeries necessitate meticulous preoperative planning, emphasizing advanced imaging (CT for nasal, laryngoscopy for laryngeal) and precise patient positioning (sternal with elevated nose for dorsal rhinotomy, dorsal recumbency with neck extended for laryngeal procedures) to ensure adequate exposure and minimize anatomical risks. Key anatomical risks include the cribriform plate and ethmoid turbinates in nasal surgery, and recurrent laryngeal nerves and arytenoid cartilages in laryngeal surgery.
• Airway security is paramount, with preplaced endotracheal tubes being standard for nasal surgery, while laryngeal procedures may require transient endotracheal tube removal or a temporary tracheostomy for optimal luminal access. Postoperative monitoring for laryngeal edema and stridor is critical, with potential interventions including reintubation or tracheostomy.
• Hemorrhage control is a significant intraoperative challenge, particularly in nasal surgery due to rich vascularization from branches of the maxillary artery (sphenopalatine, major palatine, ethmoidal arteries). Techniques include epinephrine-soaked sponges, suction, and temporary packing, while laryngeal bleeding is typically less voluminous but managed with direct pressure and bipolar electrocautery.
• Common failure modes include incomplete exposure of caudal nasal structures (ethmoid region, frontal sinus) during nasal surgery, and postoperative laryngeal stenosis or arytenoid cartilage instability following laryngeal procedures. These complications underscore the importance of deliberate incision planning and careful dissection to preserve critical structures.
• The choice of surgical approach for nasal lesions is dictated by lesion location and extent, with dorsal rhinotomy offering the widest exposure for caudal or ethmoid involvement, while lateral or ventral rhinotomies are reserved for more focal or nasopharyngeal lesions, respectively. Each approach carries specific risks, such as oronasal fistula formation with ventral rhinotomy.

This article describes the surgical approaches used to access the nasal cavity and larynx in dogs and cats. It is written for practicing veterinarians who perform or assist in upper respiratory surgery and need a structured reference for patient positioning, incision planning, exposure techniques, and postoperative airway management. The content focuses on procedural principles instead of disease-specific treatment, and it assumes familiarity with regional anatomy and basic surgical instrumentation.

The nasal cavity and larynx present distinct surgical challenges. The nasal cavity is a narrow, rigid osseous tube with a rich vascular supply and direct communication with the paranasal sinuses and oral cavity. The larynx is a mobile cartilaginous valve that must remain patent during inspiration and competent during swallowing. Both regions require careful preoperative imaging, deliberate patient positioning, and a clear plan for airway security before the first incision. This article provides the conceptual framework and stepwise approach for each region, with emphasis on the decisions that determine surgical success and patient safety.

At a Glance

Anatomic Basis for Surgical Access

The nasal cavity in dogs and cats is a paired chamber divided by the nasal septum and filled with delicate turbinate scrolls that project from the lateral and dorsal walls. The cavity extends from the external nares rostrally to the cribriform plate caudally, which separates it from the cranial vault. The dorsal nasal concha and ethmoid turbinates occupy the caudal two-thirds of the cavity, and the ventral nasal concha fills much of the rostral one-third. The maxillary recess and frontal sinus communicate with the caudal nasal cavity through narrow ostia. Surgical exposure must account for these three-dimensional relationships because the turbinates obscure direct visualization of the caudal cavity and sinus openings from a rostral approach.

The larynx sits at the caudal aspect of the oropharynx, suspended between the hyoid apparatus and the trachea. Its cartilaginous framework includes the epiglottis, thyroid cartilage, cricoid cartilage, and paired arytenoid cartilages. The recurrent laryngeal nerves run in the carotid sheath and enter the larynx caudal to the cricothyroid articulation, supplying all intrinsic laryngeal muscles except the cricothyroid. The cranial laryngeal nerves pierce the thyrohyoid membrane and provide sensory innervation to the laryngeal mucosa and motor supply to the cricothyroid muscle. The arytenoid cartilages articulate with the cricoid cartilage and support the vocal folds and corniculate processes. The rima glottidis, the narrowest portion of the upper airway, is bounded by the vocal folds ventrally and the arytenoid cartilages dorsolaterally. Surgical approaches to the larynx must preserve the recurrent laryngeal nerves and maintain the structural integrity of the arytenoid cartilages to avoid postoperative airway compromise.

The vascular supply of both regions influences surgical planning. The nasal cavity receives blood from the sphenopalatine, major palatine, and ethmoidal arteries, all branches of the maxillary artery. The larynx is supplied by the cranial and caudal laryngeal arteries, branches of the cranial thyroid and caudal thyroid arteries respectively. Hemorrhage during nasal surgery can be brisk and obscuring, while laryngeal bleeding is usually less voluminous but can still compromise a narrow surgical field. The MSD Veterinary Manual provides species-specific anatomic summaries that are useful for preoperative review, and the American College of Veterinary Surgeons publishes specialist guidance on surgical conditions and expected outcomes in these regions.

Patient Positioning and Preparation

Positioning for nasal surgery depends on the chosen approach. For a dorsal rhinotomy, the patient is placed in sternal recumbency with the nose elevated on a sandbag or rolled towel so that the dorsal nasal plane is horizontal. The head is secured with tape across the maxilla, and the eyes are protected with lubricant and padded shields. The surgical field includes the dorsal nasal surface from the nasal planum to the frontal sinus, and the skin is clipped and aseptically prepared. For a ventral rhinotomy, the patient is placed in dorsal recumbency with the maxilla elevated and the mandible retracted caudally. This approach provides access to the ventral nasal cavity and the hard palate but requires careful protection of the endotracheal tube, which may be redirected through a pharyngostomy or temporary tracheostomy to keep the oral cavity clear.

Laryngeal surgery is performed with the patient in dorsal recumbency and the neck extended over a rolled towel placed under the cervical spine. The ventral cervical region is clipped from the mandible to the thoracic inlet. The endotracheal tube is secured and its position confirmed before draping. For procedures that require visualization of the laryngeal lumen, the tube may be temporarily withdrawn into the proximal trachea or replaced with a sterile tube passed through a temporary tracheostomy. This decision is made preoperatively based on the planned procedure and the surgeon's preference for maintaining a sterile field.

Airway Management Principles

Airway security is the central concern in all upper respiratory surgery. The endotracheal tube provides a protected airway during induction and maintenance of anesthesia, but it occupies space within the surgical field. For nasal surgery, the tube is usually left in place and positioned so that it does not obstruct the nasopharynx. A cuffed tube prevents aspiration of blood and irrigation fluid that drains caudally from the nasal cavity. For laryngeal surgery, the tube may obstruct access to the dorsal larynx and arytenoid cartilages. In these cases, a temporary tracheostomy placed at the level of the mid-cervical trachea allows the surgeon to remove the orotracheal tube and work within an unobstructed laryngeal lumen. The tracheostomy tube is placed before the definitive procedure and maintained until laryngeal swelling has resolved.

Postoperative airway management begins before the patient leaves the operating room. Extubation is performed only when the patient is swallowing and has adequate respiratory effort. Laryngeal edema is the most common cause of postextubation obstruction, and its severity is influenced by the duration of surgery, the degree of tissue manipulation, and the patient's individual response. Patients that undergo laryngeal surgery should be monitored in an intensive care setting for at least 12 to 24 hours, with continuous assessment of respiratory rate, effort, and auscultable airway sounds. Stridor at rest, increased inspiratory effort, or progressive cyanosis indicates impending obstruction and requires immediate intervention, which may include reintubation, corticosteroid administration, or placement of a temporary tracheostomy. The American Veterinary Medical Association publishes practice resources on perioperative patient monitoring that are applicable to these cases.

Imaging and Preoperative Planning

Diagnostic imaging precedes surgical planning in both regions. For the nasal cavity, computed tomography (CT) provides the most accurate assessment of lesion extent, turbinate destruction, and involvement of the cribriform plate or frontal sinus. Survey radiography is less sensitive but may be used when CT is unavailable. The decision to approach the nasal cavity dorsally, ventrally, or endoscopically depends on the location and extent of the lesion. Rostral lesions may be accessible through a ventral approach or rhinoscopy, while caudal lesions involving the ethmoid region or frontal sinus typically require a dorsal rhinotomy. The cribriform plate must be evaluated carefully on imaging before any caudal nasal procedure, because breaching it carries a risk of cerebrospinal fluid leakage and meningitis.

For the larynx, imaging is less commonly required but may be useful in cases of suspected neoplasia, foreign body, or traumatic injury. CT provides detailed assessment of laryngeal cartilage integrity and extralaryngeal disease, while laryngoscopy under light anesthesia allows dynamic assessment of arytenoid cartilage movement. The choice of surgical approach, ventral laryngotomy versus laryngofissure, is guided by the location of the lesion and the need for luminal versus extraluminal exposure.

Dorsal Rhinotomy: Technique and Execution

The dorsal rhinotomy provides access to the nasal cavity, nasal passages, and ethmoid labyrinth. It is the standard open approach for lesions that cannot be managed by less invasive means. The procedure begins with a midline skin incision from the level of the nasofrontal suture to the caudal third of the nasal bones. The skin, subcutaneous tissue, and periosteum are incised in one plane and elevated laterally with a periosteal elevator. The periosteum should be preserved as a separate layer for closure.

The osteotomy is performed with an oscillating saw or osteotome. The surgeon outlines a rectangular bone flap that extends from the nasofrontal suture rostrally to approximately 60 to 70 percent of the nasal bone length. The caudal margin of the flap should sit over the ethmoid region when ethmoid access is required. The rostral margin must not extend beyond the nasal cartilage, where the bone becomes thin and fractures unpredictably. The lateral margins are positioned just medial to the nasolacrimal duct and the angularis oculi vein. The bone flap is elevated with a periosteal elevator and preserved in saline-soaked gauze.

The nasal mucosa is then incised along the same rectangular margins. The mucosa is elevated and reflected, exposing the nasal cavity. The nasal septum is visible along the midline, and the dorsal and ventral nasal conchae fill the lateral compartments. The surgeon can now inspect the caudal nasal cavity, the ethmoid labyrinth, and the nasopharynx with a headlamp or rigid endoscope. Biopsy samples are collected from any abnormal tissue, and the lesion is debulked with rongeurs, curettes, or suction.

Closure begins with reapposition of the nasal mucosa with simple interrupted sutures of 4-0 or 5-0 absorbable monofilament. The bone flap is replaced and secured with small gauge wire or polydioxanone suture passed through predrilled holes. The periosteum is closed as a separate layer, followed by the subcutaneous tissue and skin. A light pressure bandage is applied for 12 to 24 hours to reduce dead space and seroma formation. The bandage must not occlude the nares.

Lateral Rhinotomy and Alternative Nasal Approaches

The lateral rhinotomy is used for lesions confined to the ventral nasal meatus or the ventral aspect of the nasal cavity. The skin incision is made parallel to and 5 to 10 mm ventral to the nasomaxillary suture. The underlying bone is exposed, and an osteotomy is created through the maxilla and nasal bone at their junction. This approach provides direct access to the ventral meatus and the root of the nasal cavity without the morbidity of a full dorsal flap. The lateral approach is less commonly performed than the dorsal rhinotomy but is useful for focal lesions in the rostral nasal cavity.

The ventral rhinotomy, performed through the hard palate, is reserved for lesions of the caudal nasal cavity and nasopharynx that are inaccessible from a dorsal approach. The patient is positioned in dorsal recumbency with the maxilla elevated. A midline incision is made through the palatal mucosa and bone, and the nasal cavity is entered from below. This approach carries a higher risk of oronasal fistula formation and requires meticulous two-layer closure. It is rarely the first choice in dogs and cats.

For rostral nasal lesions, a simple nasal planum reflection or a rostral maxillectomy may be more appropriate than a full rhinotomy. The choice of approach depends on the location and extent of the lesion, the need for complete excision versus debulking, and the surgeon's familiarity with each technique. The dorsal rhinotomy offers the widest exposure and is the most versatile, while the lateral and ventral approaches are more limited but preserve more of the normal nasal architecture.

Approach Selection by Condition

The following table summarizes the recommended approach based on lesion location and surgical goal. The selection should be confirmed with preoperative imaging, as the imaging findings may alter the planned approach.

The table reflects the general principles of surgical access. The final decision is made intraoperatively after the nasal cavity is inspected. If the lesion extends beyond the planned exposure, the osteotomy can be extended with an oscillating saw. The surgeon should always have a backup plan for wider exposure.

Laryngeal Surgery: Positioning and Exposure

The larynx is approached through a ventral midline incision over the larynx and cranial trachea. The patient is placed in dorsal recumbency with the neck extended and a rolled towel placed beneath the cervical spine. The incision extends from the basihyoid bone to the mid-cervical trachea. The paired sternohyoid and sternothyroid muscles are separated on the midline and retracted laterally with self-retaining retractors. The larynx is then visible beneath the thin fascia and the thyroid gland.

The thyropharyngeus and cricopharyngeus muscles are identified and may be partially divided or retracted to expose the dorsal aspect of the larynx. The cranial laryngeal nerve and the recurrent laryngeal nerve must be identified and preserved where possible. The recurrent laryngeal nerve runs in the groove between the trachea and the esophagus and enters the larynx caudal to the cricoid cartilage. The cranial laryngeal nerve enters the thyrohyoid membrane and supplies the cricothyroid muscle.

The larynx is stabilized with a stay suture placed through the thyroid cartilage or by grasping the arytenoid cartilages with atraumatic forceps. The surgeon can then perform a laryngotomy, a partial arytenoidectomy, or a laryngeal tie-forward procedure depending on the indication. The laryngotomy incision is made through the midline of the thyroid cartilage and the cricothyroid membrane, providing access to the laryngeal lumen. The incision is closed with simple interrupted sutures placed through the cartilage and the overlying soft tissues.

Postoperative Airway Management After Nasal and Laryngeal Surgery

The immediate postoperative period is the highest risk phase for airway compromise. Swelling of the nasal mucosa, laryngeal edema, and hemorrhage can all obstruct the airway. The patient should be monitored continuously for the first 12 to 24 hours in an intensive care setting. Pulse oximetry and capnography provide continuous assessment of oxygenation and ventilation. A decline in SpO2 below 94 percent or a rise in end-tidal CO2 above 45 mm Hg warrants immediate intervention.

The patient is positioned in sternal recumbency with the head elevated to reduce dependent edema. Cool, humidified oxygen is administered by mask or nasal cannula. The nares are kept clear of blood and secretions with gentle suction. The patient should not be allowed to become excited or to struggle, as this increases venous pressure and exacerbates hemorrhage.

For laryngeal surgery, a temporary tracheostomy tube may be placed at the time of surgery if the airway is considered at risk. The tube is maintained until the laryngeal swelling has resolved, typically 24 to 72 hours. The tube is then removed and the stoma is allowed to heal by second intention. The decision to place a tracheostomy tube is made preoperatively based on the anticipated degree of swelling and the patient's baseline respiratory status.

The patient is fed a soft diet for 5 to 7 days after laryngeal surgery to reduce movement of the larynx during swallowing. Water is offered freely. Coughing and sneezing are expected after nasal surgery and should not be suppressed unless they are persistent or productive of large volumes of blood. The patient is re-examined at 2 weeks and again at 6 to 8 weeks postoperatively to assess healing and to confirm that the surgical goal has been achieved. Repeat imaging is performed if there is any concern about incomplete resection or recurrence. The American College of Veterinary Surgeons animal health resources provide additional guidance on expected outcomes and postoperative monitoring for these procedures.

Documentation and Surgical Reporting

The surgical record should include the preoperative imaging findings, the approach used, the findings at surgery, and the extent of resection or debulking. Photographs of the surgical field and of the resected tissue are valuable for the medical record and for client communication. The tissue is submitted for histopathology in all cases where neoplasia is suspected, as the histologic diagnosis determines the need for adjuvant therapy. The MSD Veterinary Manual professional edition provides a framework for interpreting histopathologic findings and planning follow-up care. The record should also note any intraoperative complications, the estimated blood loss, and the postoperative airway management plan.

Recognized Complications and Early Detection

Hemorrhage is the most immediate intraoperative complication in nasal surgery. The dorsal and lateral rhinotomy approaches transect branches of the sphenopalatine and ethmoidal arteries, and venous bleeding from the dorsal nasal venous plexus can be brisk. Early detection relies on continuous communication between surgeon and anesthetist. A falling mean arterial pressure with rising heart rate in the face of visible bleeding warrants immediate packing and reassessment of exposure. The endoscopic sheep model of endonasal vascular injury demonstrates that mean arterial pressure can fall from 65.7 to 39.1 mm Hg within minutes of carotid injury, with survival times under one hour without effective control, which underscores how rapidly blood loss can become critical in confined nasal fields.

Postoperative hemorrhage is detected by serosanguinous nasal discharge, frequent swallowing, or frank blood at the nares. Mild oozing is managed with head elevation and cold compresses. Persistent bleeding requires re-anesthesia and packing removal to identify the source. In cats, the nasal cavity is proportionally smaller and more vascular per unit volume than in dogs, so even minor trauma can produce significant blood loss.

Subcutaneous emphysema and pneumomediastinum occur when the nasal or frontal sinus cavity is closed without adequate drainage or when the patient sneezes forcefully against a sealed incision. Detection is by palpation of crepitus over the dorsum or cervical region, often within 12 to 24 hours postoperatively. Thoracic auscultation and, if uncertain, thoracic radiography confirm extension.

Oro-nasal fistula formation is a late complication of lateral rhinotomy when the incision violates the palatine mucosa. Detection is by observation of food material exiting the nares during eating or by direct oral examination under sedation. The discriminating feature is timing: fistulae present days to weeks after surgery, whereas persistent nasal discharge from sinusitis presents earlier.

Common Errors and Corrective Actions

The most frequent error in dorsal rhinotomy is placing the bone flap too far rostrally or caudally. A flap positioned rostral to the canine tooth roots fails to expose the caudal nasal cavity and ethmoid region, while a flap too caudal risks entering the frontal sinus without adequate nasal access. Corrective action is to confirm the planned osteotomy margins against preoperative imaging and to use the nasofrontal suture line as the caudal boundary.

A second error is failure to preserve the nasal septum during tumor debulking or biopsy. The septum provides structural support and a surgical landmark. Aggressive septal resection leads to midface collapse and chronic nasal stenosis. The corrective action is to limit septal excision to the visibly diseased portion and to document the extent of resection in the surgical report.

In laryngeal surgery, the most common error is inadequate exposure of the arytenoid cartilages. The surgeon who relies solely on the mouth gag without a laryngoscope or headlamp will struggle to visualize the corniculate processes. The corrective action is to use a self-retaining laryngoscope or to have an assistant retract the soft palate dorsally with a spay hook.

Students frequently misidentify the vocal folds as the arytenoid cartilages when performing unilateral arytenoid lateralisation. The vocal folds are pale, thin bands, the arytenoid cartilages are firm, rounded prominences dorsal to the folds. The discriminating check is to palpate the corniculate process with a probe before placing the suture.

Limitations of Current Evidence

The evidence base for nasal and laryngeal surgical approaches in dogs and cats is largely derived from case series and expert opinion instead of randomised controlled trials. The American College of Veterinary Surgeons provides specialist summaries of expected outcomes and postoperative management, but these are consensus-based instead of evidence-graded. The MSD Veterinary Manual similarly offers practical guidance without systematic review of comparative outcomes.

Expert opinion differs on three points. First, whether dorsal rhinotomy or lateral rhinotomy provides superior access to the caudal nasal cavity. Some surgeons favour dorsal for bilateral disease, others prefer lateral for unilateral disease with less morbidity. Second, whether the bone flap should be replaced and fixed or discarded. Replacement preserves cosmesis but risks sequestration, discard simplifies closure but leaves a permanent dorsal nasal defect. Third, whether prophylactic tracheostomy is indicated after bilateral arytenoid lateralisation. Some authorities recommend it routinely, others reserve it for cases with preoperative laryngeal collapse.

The human literature on endonasal approaches and saddle nose reconstruction demonstrates that graft resorption and aesthetic outcomes vary by graft material, with calvarial bone showing the most favourable long-term results. Whether these findings translate to veterinary patients is uncertain, as dogs and cats have different nasal airflow dynamics and healing responses. Similarly, the anthropometric principles used in human craniofacial cleft repair have limited direct application to veterinary nasal surgery, where the dorsal nasal plane differs substantially from the human nose.

Referral, Consultation, and Reporting

Referral to a veterinary surgical specialist is warranted when the lesion extends beyond the nasal cavity into the cribriform plate, orbit, or cranial vault, when the patient has coagulopathy, or when the surgeon has not performed the procedure recently. Specialist consultation is also appropriate for revision surgery after failed rhinotomy or laryngoplasty.

Laboratory involvement is indicated when histopathology of resected tissue is required, when coagulopathy is suspected preoperatively, or when culture and sensitivity of sinus contents will guide antimicrobial therapy. Regulatory reporting is rarely required for routine nasal or laryngeal surgery. However, if a patient is suspected of having a notifiable disease, such as aspergillosis in a region where it is reportable, or if a surgical complication results in death and the owner requests investigation, the attending veterinarian should consult the relevant animal health authority. The World Organization for Animal Health maintains terrestrial animal health standards that define reporting obligations for listed diseases, and veterinarians should confirm their local requirements.

Frequently Asked Questions

How Do I Decide Between Dorsal Rhinotomy and Less Invasive Nasal Approaches When Advanced Imaging Is Unavailable?

Without computed tomography, base the decision on lesion location inferred from conscious oral examination, skull radiography, and dental assessment. Bilateral disease, disease caudal to the third premolar, or involvement of the frontal sinus favours a dorsal rhinotomy. Unilateral rostral disease may be approached via lateral rhinotomy. When imaging is limited, extend the exposure generously because incomplete visualization is the most common reason for incomplete resection. The American College of Veterinary Surgeons small animal resources describe case selection and expected outcomes for each approach. If the lesion extends into the cribriform plate region, warn the owner that complete excision is unlikely and that adjunctive therapy will be required.

What Equipment Substitutions Are Acceptable When a Full Instrument Set Is Not Available?

An oscillating saw is preferred for bone flaps, but a high-speed bur with a fine cutting bit creates an acceptable osteotomy if used with continuous saline irrigation to prevent thermal necrosis. Osteotomes are a poor substitute because they propagate fractures unpredictably through the thin canine nasal bones. For laryngeal surgery, a standard spay hook retracts the larynx effectively when specialised laryngeal retractors are absent. Headlamp illumination is strongly recommended, if unavailable, a fiber-optic light source held by an assistant is the minimum acceptable alternative. Stay sutures placed through the thyroid cartilage replace self-retaining retractors. The MSD Veterinary Manual professional edition provides background on standard surgical instrumentation expectations, and deviations from ideal equipment should be documented in the surgical record.

How Does the Surgical Approach Differ in Brachycephalic Compared With Dolichocephalic Breeds?

Brachycephalic dogs have shortened nasal bones, a domed frontal sinus, and often concurrent stenotic nares that complicate postoperative airflow. The nasal cavity is relatively deeper dorsoventrally, so a dorsal rhinotomy flap must be positioned more rostrally and the osteotomy margins checked against preoperative skull dimensions. Turbinate architecture is compressed, increasing the risk of inadvertent penetration of the cribriform plate during curettage. In dolichocephalic breeds, the elongated nasal cavity may require extending the rhinotomy caudally to the frontonasal suture line. Feline skulls are smaller and the nasal bones thinner, so a high-speed bur with a fine bit is safer than an oscillating saw. The WOAH terrestrial animal health standards do not address breed-specific technique, but they reinforce that anatomic variation should be anticipated and documented.

What Should I Document in the Surgical Record Beyond the Standard Operative Notes?

Record the exact osteotomy boundaries, the number and location of bone flaps, whether turbinates were excised or only reflected, and the method of nasal packing if used. Note the volume of saline used for irrigation, because excessive irrigation can cause hypothermia in small patients. For laryngeal procedures, document the degree of arytenoid abduction achieved, the suture material and needle type used for arytenoid lateralisation, and the number of suture throws. Photographs taken before closure are valuable for postoperative comparison and for referral if revision is needed. Record any intraoperative complication, including hemorrhage estimates and the response to packing. The American Veterinary Medical Association practice resources provide general guidance on medical record content, and specific surgical details should follow the standards expected by your local regulatory body.

How Do I Manage the Patient When Postoperative Airway Obstruction Develops Despite a Patent Surgical Airway?

First, confirm patency of the nasal passages by passing a soft catheter or by observing condensation on a cold spatula held at the nares. If obstruction is present, remove visible blood clots with gentle suction and reapply topical vasoconstrictors if previously used. For laryngeal patients, assess for arytenoid edema and consider a single dose of an anti-inflammatory agent, but consult a current formulary for dosing. If obstruction persists despite these measures, place a temporary tracheostomy tube. The decision to place a tracheostomy should be made early instead of after progressive respiratory fatigue. The American College of Veterinary Surgeons small animal resources describe postoperative monitoring expectations after upper airway surgery, and patients should be observed continuously until they are fully awake and breathing comfortably.

How Should I Explain the Risks and Expected Outcomes to an Owner Who Is Hesitant About Surgery?

Use plain language that distinguishes between the surgical procedure and the underlying disease. Explain that the approach provides access, not cure, and that the outcome depends on the nature of the lesion found at surgery. Describe the possibility of recurrence, the need for postoperative monitoring, and the expected recovery timeline, including temporary nasal discharge or voice change. Provide written instructions for home care, including activity restriction and signs that warrant immediate recheck. The MSD Veterinary Manual professional edition offers owner-level summaries of common surgical conditions that can support your explanation. If the owner declines surgery, document the discussion and offer medical management options, but be explicit that delayed surgery may allow disease progression that makes a later approach more difficult.
