Background: Moderate laryngomalacia lies in the grey zone where the parents and treating team might hesitate to decide the treatment plan for the child. Neurodevelopmental assessment of the child was neither assessed nor incorporated in surgical decision-making in the past., Objectives: To evaluate the neurodevelopmental outcome of moderate laryngomalacia treatment strategies (surgery versus conservative)., Methods: We conducted an observational multicentric cohort study. We compared two groups of patients according to their moderate laryngomalacia treatment strategy: surgical treatment and no treatment. The neurodevelopmental outcome was assessed by Griffiths-III developmental scales., Results: A total of 150 children were diagnosed with moderate laryngomalacia of which 56 were successfully treated with surgery and 94 improved without intervention. The median Griffiths-III developmental quotients (DQs) of subscales A, B, C, E, and general development were significantly higher in the surgically treated group compared to conservatively treated ones., Conclusion: Untreated moderate laryngomalacia cases have worse neurodevelopmental outcomes than surgically treated cases., Competing Interests: Declaration of competing interest There is no conflict of interest., (Copyright © 2024 Elsevier B.V.

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., (© 2021.
