OBJECTIVE: Cricotracheal resection (CTR) and laryngotracheoplasty (LTP) are open surgical treatments for severe subglottic stenosis. This study aims to compare the applications and outcomes of these techniques.

METHOD: Patients with subglottic stenosis at a tertiary academic institution from 2000 to 2012 were identified by diagnosis codes. Patients who underwent LTP or CTR were included. Records were reviewed for treatment data and outcomes. Patients with a history of head and neck malignancy or stenosis without cricoid involvement were excluded.

RESULT: Sixty-one and 20 patients underwent LTP and CTR, respectively. When comparing patients receiving LTP and CTR, there was a significant difference in stenosis etiology (P=.014). The groups were similar in Cotton-Myer grade (P=.102). At last follow-up, 80.3% of LTP patients and 90.0% of CTR patients were decannulated. On multivariate analysis, there was a significant association between stenosis grade and decannulation in the LTP group (P=.01). Decannulation was not associated with stenosis grade in the CTR group. In both groups, there was no significant association between decannulation and sex, stenosis etiology, or stenosis length.

CONCLUSION: Cricotracheal resection and LTP have both shown excellent long-term decannulation rates. Etiology and stenosis grade are likely to be determining factors when recommending specific surgical interventions for subglottic stenosis.
