Brachycephalic Airway Surgery

The breathing effort required by an uncorrected brachycephalic airway is not a quirk or a personality trait — it is a medical condition that causes real distress and has serious long-term consequences:

• Chronic negative pressure from straining to breathe stretches and weakens the larynx (voice box) over time, eventually causing laryngeal collapse — a condition that is much harder to treat than the original anatomical defects
• The same pressure pulls everted saccules out of the laryngeal walls, adding another layer of obstruction
• Sleep-disordered breathing and exercise intolerance develop progressively
• Gastroesophageal reflux, regurgitation, and vomiting are commonly secondary to the swallowing of large amounts of air

Surgical correction performed before laryngeal collapse develops — ideally in dogs under two years of age — can substantially improve breathing quality, exercise tolerance, and long-term prognosis.

Surgery is performed under general anesthesia with special attention to airway management during anesthetic induction and recovery — the most vulnerable periods for brachycephalic patients. The components addressed include:

• Stenotic nares correction (alaplasty): wedges of tissue are removed from the nostril wings and the edges sutured, creating a wider nasal opening that substantially reduces airflow resistance
• Elongated soft palate resection (staphylectomy): the excess soft palate tissue is trimmed to the appropriate length so it no longer contacts the epiglottis and partially obstructs the airway with each breath — performed carefully with scissors or laser with suturing of the cut edge
• Everted laryngeal saccule removal: when saccules are everted, they are grasped and excised through the mouth; this step is performed if saccules are present and contributing to obstruction

All three components are typically addressed in the same anesthetic episode when indicated.

A thorough pre-operative evaluation ensures the safest possible anesthetic experience for these at-risk patients:

• Airway examination under sedation or anesthesia to directly assess the soft palate length, larynx, and saccule status
• Chest radiographs to screen for aspiration pneumonia, which occurs more frequently in brachycephalic pets
• Pre-anesthetic bloodwork
• Discussion of weight — overweight brachycephalic pets face significantly higher anesthetic risk, and even modest weight loss before surgery makes a meaningful difference
• Surgery scheduled in the cool part of the day and in cooler seasons when possible; these patients do not tolerate heat stress
• Food withheld the night before; water per the team's guidance

The post-operative period requires close monitoring because airway swelling peaks in the first 12 to 24 hours after surgery:

• Day of surgery: patients are kept intubated (breathing tube in place) until fully awake and then monitored in hospital until breathing is stable — most are discharged the same evening or the following morning
• Days 1–5: soft food only; small, frequent meals to reduce regurgitation risk; elevated food bowl position can help
• Weeks 1–3: restricted exercise — no running, excitement, or exposure to heat; leash walks only in cool weather
• E-collar if the pet paws at the nose incision
• Recheck at 10 to 14 days; many owners notice a marked improvement in breathing and sleep quality within the first week

Brachycephalic airway surgery carries specific risks tied to the pre-existing airway anatomy:

• Post-operative swelling: airway edema (swelling) in the first 24 hours is the primary risk; this is why close post-operative monitoring is standard — rarely, a temporary tracheostomy tube is placed to protect the airway during recovery
• Aspiration: regurgitation is common in brachycephalic breeds; anti-nausea medication and careful feeding practices minimize the risk of aspiration during recovery
• Laryngeal collapse: if laryngeal collapse is already present before surgery, the correction of nares and palate may not provide the expected benefit — the surgeon will discuss findings directly if this is identified during the procedure
• Incomplete resolution: most pets breathe substantially better after surgery, but the anatomy is not made normal — it is improved. Ongoing weight management and avoiding heat and extreme exercise remain lifelong commitments

For most young brachycephalic patients without advanced laryngeal changes, the surgery is transformative — owners frequently describe their pet as a different animal afterward.
