Dogs were included if they were treated with ala-vestibuloplasty and H-pharyngoplasty with a CO2<\/jats:sub> laser. Signalment, physical examination findings, grades at admission of clinical signs associated with respiratory and digestive systems, diagnostic test results, postoperative treatments, and short-term follow-up results were extracted from medical records. Long-term follow-up of > 12 months was evaluated via questionnaire. Generalized ordered logistic regression was used for bivariable and multivariable analyses.<\/jats:p>\n<\/jats:sec>\n\nRESULTS<\/jats:title>\nOverall mortality rate was 2.6%. Median duration of follow-up was 36 months (12 to 91 months), and 341 (80.6%) dog owners completed the questionnaire. Major complications included respiratory distress (2.1%), heatstroke (0.5%), and bronchopneumonia (0.5%). No dogs required revision surgery. Improvement in signs associated with the respiratory and digestive systems was reported in 72% and 34% of the dogs, respectively, and owners\u2019 satisfaction was high (97.1%). Risk of death increased by 29.8% (95% CI, 11.8% to 50.7%) for every 1-year increase in age.<\/jats:p>\n<\/jats:sec>\n\nCONCLUSION AND CLINICAL RELEVANCE<\/jats:title>\nH-pharyngoplasty was possible in all dogs with BOAS, including those previously treated with conventional surgery and was associated with low morbidity and improved respiratory and digestive signs. H-pharyngoplasty combined with ala-vestibuloplasty may be an alternative treatment for even the most severely affected dogs.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.20.09.0534","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T21:26:38Z","timestamp":1639603598000},"page":"S65-S73","source":"Crossref","is-referenced-by-count":13,"title":["Complications, prognostic factors, and long-term outcomes for dogs with brachycephalic obstructive airway syndrome that underwent H-pharyngoplasty and ala-vestibuloplasty: 423 cases (2011\u20132017)"],"prefix":"10.2460","volume":"260","author":[{"given":"Julien P.R.","family":"Carabalona","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"Le Boedec","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cyrill M.","family":"Poncet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"B1","series-title":"Vet Surg","first-page":"271","article-title":"Outcomes and prognostic factors of surgical treatments for brachycephalic obstructive airway syndrome in 3 breeds","volume":"46","year":"2017","unstructured":"Liu NC, Oechtering GU, Adams VJ, et al.
