Microdebrider-Assisted Supraglottoplasty for Laryngomalacia
Objective To describe our series in the surgical treatment of laryngomalacia using a microdebrider. Methods A retrospective review of patients undergoing supraglottoplasty for laryngomalacia at a tertiary children's hospital between October 2004 and February 2008 was performed. Patients with complex co-morbidities and those undergoing alternative methods for supraglottoplasty were excluded. Patient charts and operative reports were reviewed to assess demographic characteristics, co-morbidities, procedural times, hospitalizations, intra-operative and post-operative complications, and post-operative outcome. Main outcome measures included complications, pain, resolution of stridor, presence of aspiration, and need for revision surgery. Results 27 patients underwent microdebrider-assisted supraglottoplasty. Mean age at diagnosis was 109 days; mean age at time of the procedure was 187 days. 18 Eighteen patients (67%) had gastro-esophageal reflux at the time the laryngomalacia was diagnosed. Average operative time was 35.7 minutes (std. dev. 12.9, range 11–65 minutes). No intra-operative complications or device problems were noted. Only 2 patients remained intubated at the conclusion of the procedure; no patient required tracheotomy or revision supraglottoplasty. One patient had post-operative aspiration, which later resolved. One patient was readmitted for stridor one month following her procedure. There was no pain from the procedure, as all patients immediately resumed a diet. All patients had eventual resolution of stridor. Conclusions This is the largest series of patients that underwent microdebrider-assisted supraglottoplasty for laryngomalacia. This procedure is safe, without pain, and effective in patients with laryngomalacia. Microdebrider- assisted supraglottoplasty is the method of choice for supraglottoplasty in our institution.
