    Abstract:
    OBJECTIVE: To report the long-term outcome of permanent tracheostomy for the management of severe laryngeal collapse secondary to brachycephalic airway obstructive syndrome. STUDY DESIGN: Retrospective case series. ANIMALS: Fifteen brachycephalic dogs with severe laryngeal collapse treated with permanent tracheostomy. METHODS: Follow-up data were obtained from medical records or via telephone conversation with the owners. The Kaplan-Meier estimator was used to calculate median survival time. Death was classified as related or unrelated to tracheostomy surgery. Complications were classified as major when they were life-threatening or required revision surgery. Owners were asked to classify the postoperative quality of life as improved, unchanged, or worse and the management of the stoma as simple or demanding. RESULTS: The median survival time was 100 days. Major complications were diagnosed in 12 of 15 (80%) dogs, resulting in death in 8 (median survival time 15 days) and revision surgery in 4 dogs. Seven of 15 (47%) dogs died of unrelated causes or were alive at the end of the study (median survival time 1982 days). The postoperative quality of life of 9 dogs was judged as markedly improved. Stoma management was defined as simple in 8 dogs and demanding in 4. CONCLUSION: Permanent tracheostomy was associated with a high risk of complications and postoperative death in brachycephalic dogs. However, long-term survival (exceeding 5 years) with a good quality of life was documented in 5 of 15 dogs. CLINICAL SIGNIFICANCE: Permanent tracheostomy is a suitable salvage option in brachycephalic dogs with severe laryngeal collapse that did not improve following more conservative surgeries.
