Supraglottoplasty in Neonates under One Month of Age

Abstract

Objectives: Examine outcomes of patients 1 month of age or less who received supraglottoplasty. Demonstrate the feasibility and safety of supraglottoplasty in neonates <1 month of age. Methods: Charts were reviewed from 2015-2017. Patients with previously identified laryngomalacia requiring surgical intervention and age 1 month or less were identified. We collected data on age, gender, surgical technique, other airway lesions, time to extubation and discharge, and comorbidities. Results: Six patients met the inclusion criteria of which four were male and two were female. Average age at time of surgery was 19.5 days. All patients had diagnosis of laryngomalacia made on flexible or direct laryngoscopy with increased work of breathing, reports of cyanotic episodes, or oxygen desaturations. All had feeding difficulties, and three had signs and history consistent with gastroesophageal reflux. Two patients underwent supraglottoplasty by CO2 laser treatment alone, one patient received cold steel treatment alone, and the remaining three patients received cold steel with supplemental microdebrider treatment. Out of six patients, five were extubated within 5 days of their procedure. The average time to extubation was 1.8 days. The average time to discharge was 24.25 days following surgery. Two patients required revisions. Conclusions: Supraglottoplasty in children younger than 1 month of age is rare. Despite the rare occurrence, it appears to be feasible early in life in treating laryngomalacia. Neonates with respiratory failure, apneas, and cyanosis, or difficulty feeding due to laryngomalacia should be evaluated and treated with supraglottoplasty.

Disposition to pediatric intensive care unit post supraglottoplasty repair: A systematic review

“…Younger age was observed in patients admitted to the PICU in the studies included in our review, but not found to be statistically significant. However, in two studies specifically investigating young patients undergoing supraglottoplasty (less than 2 months), age was found to be associated with a more difficult post-operative course, including prolonged intubation, which corresponds with the observations made in our studies [23,25].…”
