Abstract

Purpose

The present study aims to review the outcomes of coblation supraglottoplasty performed for children with different types of laryngomalacia, and we discuss the factors affecting these outcomes.

Methods

We retrospectively reviewed the medical records of laryngomalacia patients admitted to the Otorhinolaryngology Department, Mansoura University, from 2010 to 2020. We examined the patient’s demography, symptoms, comorbidities, type of laryngomalacia, oxygen saturation, and final outcomes.

Results

Our study included 235 patients; 122 patients responded to medical therapy, while 113 underwent surgical management. There is a significant relation between the types and therapy they underwent (p ≤ 0.001). Larger percentage within type I underwent medical therapy. There is a statistically significant difference between the studied groups regarding age at surgery. On pairwise comparison, patients with type II had the lowest age significantly at the surgery when compared with each other individual group (p ≤ 0.001). On multivariate regression analysis, the presence of comorbid congenital heart disease, neurological comorbidities significantly increased the risk of failure of surgical intervention by 17.32 and 5.803 folds, respectively.

Conclusions

Coblation supraglottoplasty is effective and safe to treat severe laryngomalacia. Different morphological types of laryngomalacia require slight surgical variations of coblation supraglottoplasty. The presence of comorbid congenital heart disease, neurological comorbidities significantly increased the risk of failure of surgical intervention.
