Ala vestibuloplasty gains attention in stenotic nares surgery
Bottom line
Clinician’s Brief has published a new surgical guide and companion podcast episode featuring Dr. Karen Tobias, professor of small animal soft tissue surgery at the University of Tennessee, focused on ala vestibuloplasty for dogs with stenotic nares. The article argues that traditional wedge or punch resections may widen the external nostril but can leave airflow through the nasal vestibule restricted, while ala vestibuloplasty addresses both the alar wing and the obstructive alar fold. That approach aligns with a growing body of literature suggesting the technique can produce a larger increase in airway size and airflow in brachycephalic patients with moderate to severe stenosis.

Why it matters: For veterinarians managing brachycephalic obstructive airway syndrome, the piece is a practical reminder that stenotic nares aren’t just an external opening problem. BOAS guidance from ACVS notes stenotic nares are a core component of the syndrome and are commonly corrected alongside other airway procedures, while recent reviews have highlighted how much airway resistance comes from the nose. For clinicians, that means procedure selection, case selection, perioperative monitoring, and client counseling all matter, especially when pet parents assume all “nare surgeries” deliver similar results.

What to watch: Expect continued interest in comparative outcome data, especially studies that clarify when ala vestibuloplasty should replace more traditional rhinoplasty techniques in dogs with BOAS. (onlinelibrary.wiley.com)

Clinician’s Brief is spotlighting ala vestibuloplasty as a technique to maximize airflow in dogs with stenotic nares, pairing a step-by-step surgical guide with a podcast conversation featuring Dr. Karen Tobias of the University of Tennessee. The central takeaway is that in many brachycephalic dogs, narrowing is not limited to the visible external nares. Obstructive tissue within the nasal vestibule, especially the alar fold, can also contribute substantially to airflow limitation, and Tobias’ guide frames ala vestibuloplasty as a way to address both sites of obstruction.

That message lands in a broader BOAS conversation that has been shifting from simple external nare widening toward more anatomy-specific airway surgery. ACVS describes stenotic nares as one of the hallmark lesions in brachycephalic syndrome, alongside elongated soft palate and everted laryngeal saccules, and notes that correction is often performed as part of multilevel airway management. A 2024 review in Veterinary Surgery went further, reporting that stenotic nares affect more than 75% of dogs presenting for BOAS surgery and that nasal airway resistance from stenotic nares and nasal cavity obstruction accounts for about 80% of the airway resistance these dogs experience.

The Clinician’s Brief guide emphasizes why that distinction matters surgically. Traditional wedge, punch, or Trader-style resections can enlarge the external opening, but the article says vestibular airflow may remain restricted when enlarged alar folds are present. In that setting, ala vestibuloplasty removes part of the alar wing and the alar fold to widen the nasal vestibule itself. Tobias also provides procedural details that make the article especially useful for surgeons, including anatomical landmarks, blade selection, hemostatic steps, and the need to check for residual obstructive tissue before recovery.

The evidence base is still developing, but it’s moving in the same direction. A 2023 silicone-model study published in Veterinary Surgery found ala vestibuloplasty produced the largest increase in cross-sectional airway area among three rhinoplasty techniques tested, leading the authors to suggest it can be considered for French bulldogs with moderately stenotic nares and evidence of nasal vestibular stenosis. A 2024 study reported that vestibuloplasty combined with either Trader’s technique or vertical wedge resection significantly increased the cross-sectional area of both the external nares and the nasal vestibules. Meanwhile, the 2024 BOAS surgery review noted that ala vestibuloplasty has often been incorporated into newer multilevel approaches, even though it has not yet been fully evaluated as a standalone clinical procedure in dogs.

There are also signs of growing specialty uptake. Cambridge’s Queen’s Veterinary School Hospital said in 2024 that, after research from its BOAS group showed ala vestibuloplasty created the largest increase in cross-sectional airway area compared with wedge resections, the hospital adopted it as the technique used in most BOAS surgery patients. That’s not a formal consensus statement, but it does suggest at least some referral centers see the procedure as more than a niche alternative. (hospital.vet.cam.ac.uk)
Why it matters: For veterinary professionals, this is less about a single podcast and more about a decision point in BOAS surgery. If internal vestibular obstruction is a major contributor to resistance, then a procedure chosen solely for cosmetic familiarity or speed may underperform in the dogs that need the most airway gain. The flip side is that brachycephalic airway surgery still carries meaningful perioperative risk. ACVS notes these pets require close postoperative monitoring because inflammation or bleeding can obstruct the airway, and some patients may need temporary tracheostomy support. That makes preoperative assessment, referral decisions, anesthetic planning, and realistic counseling for pet parents just as important as the technical choice of nare procedure. (acvs.org)
The feline literature adds another useful signal. Recent and emerging studies in brachycephalic cats have reported improved cardiopulmonary parameters and owner-perceived quality of life after ala vestibuloplasty, reinforcing the idea that nasal obstruction can have systemic consequences and that addressing it can produce measurable benefit. Those data can’t simply be extrapolated to dogs, but they strengthen the broader case that the nasal vestibule deserves more attention in brachycephalic airway workups. (pubmed.ncbi.nlm.nih.gov)
What to watch: The next step for the field is better comparative clinical outcomes in dogs, including which BOAS phenotypes benefit most, whether ala vestibuloplasty improves long-term function beyond traditional techniques, and how often it should be paired with other upper-airway procedures rather than treated as a standalone correction.
