Outcome of laryngeal web resection with mucosal apposition for treatment of airway obstruction in dogs: 15 cases (1992--2006).

Abstract

OBJECTIVE: To evaluate long-term clinical outcome in dogs with upper airway obstruction treated with laryngeal web resection and mucosal apposition. DESIGN: Retrospective case series. ANIMALS: 15 client-owned dogs with laryngeal web formation. PROCEDURES: Medical records of dogs with laryngeal webs treated with a single procedure of web resection with mucosal apposition by use of a ventral laryngotomy were reviewed. Signalment, history, clinical signs, intraoperative complications, postoperative complications, and hospitalization time were recorded. Owners were interviewed 6 months to 6 years after surgery. RESULTS: Most dogs had a history of oral ventriculocordectomy. Duration of clinical signs ranged from 3 months to 3 years. The most common clinical sign reported was exercise intolerance. Postoperative complications were observed in 4 dogs. Follow-up information was available in 10 dogs, and clinical outcome was classified as excellent in 7 and good in 3. CONCLUSIONS AND CLINICAL RELEVANCE: A single surgical procedure of web resection with mucosal apposition for the treatment of laryngeal web formation in dogs resulted in low morbidity and was associated with a good to excellent outcome.
