Clinical Outcomes in Partial Cricotracheal Resection and Anastomosis in Subglottic and Upper Tracheal Stenosis: A 10-year Institutional Study

Ab s t r Ac t Aim and objective: The study aimed to review the clinical and surgical outcomes of partial cricotracheal resection (PCTR) and anastomosis in the management of laryngotracheal stenosis (LTS). Materials and methods: The study used a retrospective analysis of adult patients managed in a University Hospital who underwent PCTR and anastomosis from 2007 to 2017. Results: During the 10 years, 53 patients were diagnosed with cricotracheal or tracheal stenosis. Prolonged orotracheal intubation and blunt trauma were the leading causes of upper LTS. The stenosis were classified as per Myer-Cotton classification. Thirty-seven were chosen for surgical intervention. Of the patients who underwent surgical intervention, PCTR was done in 33, resection and anastomosis in 3 and 1 underwent balloon dilatation. Tube displacement and surgical emphysema were the most common complication seen postoperatively. Ninety-seven percent of the patients who underwent surgery were successfully decannulated. Conclusion: Partial cricotracheal resection is an established surgical procedure with low morbidity and mortality. Risk factors for increased morbidity include diabetes mellitus (DM), lengthy resection, and children. Rib autograft was found to be ideal for reconstruction. Prompt observation and intervention of morbidity is the key to good clinical outcomes.
