OBJECTIVES/HYPOTHESIS: This study aimed to report our experience in the management of congenital laryngeal stenosis and to compare our series and results to published data in the literature. STUDY DESIGN: Retrospective case series. Tertiary referral center for rare pediatric head and neck malformations. METHODS: Medical charts of patients diagnosed with congenital laryngeal stenosis in our institution were reviewed over a 15-year period, from 1996 to 2011. Surgical treatment consisted of an endoscopic procedure, open laryngeal surgery (OLS), or a combination of both. RESULTS: Sixteen patients met the inclusion criteria for the study and were divided in two groups: the endoscopic laryngoplasty (EL) group, with patients who underwent the endoscopic procedure as first-line treatment, and the OLS group, whose patients underwent open laryngoplasty with cartilage graft as first-line treatment. Each group contained eight patients with grade II to IV congenital stenosis. All patients, except one in the EL group, achieved a good result (<50% residual stenosis) at the end of the follow-up. CONCLUSIONS: This case series suggests that EL, with incision of the subglottic laryngeal cartilages with cold steel instruments and balloon dilation, is a safe and effective treatment for congenital laryngeal stenosis grade II to IV. This procedure could be considered as an alternative option to OLS, even as a first-line procedure. An endoscopic procedure does not preclude the possibility for an open laryngeal procedure in case of failure. A prolonged follow-up is mandatory. LEVEL OF EVIDENCE: 4.
