# Successful Treatment of Severe Laryngomalacia Due to Posterior Collapse of the Epiglottis by Correction of Glosso-Larynx (CGL): A Case Report

## TL;DR

A new surgical procedure called CGL successfully treated severe laryngomalacia in an infant by improving airway stability and reducing respiratory symptoms.

## Contribution

CGL is presented as a novel, minimally invasive treatment option for severe laryngomalacia involving tongue-larynx dynamics.

## Key findings

- CGL improved airway stability and respiratory symptoms in an infant with severe laryngomalacia.
- The procedure enhanced feeding ability and overall clinical condition without complications.
- Endoscopic follow-up confirmed functional airway expansion with limited morbidity.

## Abstract

What are the implications of the main findings?
Addressing tongue–larynx dynamics may provide a novel therapeutic option for selected cases of severe laryngomalacia.CGL may offer an alternative minimally invasive approach in the management of pediatric upper airway obstruction.

Background: Laryngomalacia is the most common cause of inspiratory stridor in infancy. While most mild cases resolve spontaneously, severe cases may require surgical intervention. We report a case of severe laryngomalacia successfully treated with correction of glosso-larynx (CGL), a surgical procedure originally developed for ankyloglossia with deviation of the epiglottis and larynx (ADEL). Methods: A 2-month-old infant with severe symptoms was evaluated using objective anatomical and functional metrics. The patient underwent CGL under local anesthesia to release restrictive tension on the hyoid-larynx complex. Results: The patient showed rapid and sustained improvement in respiratory symptoms. At the one-month follow-up, endoscopic examination confirmed functional airway expansion with limited to no morbidity. Conclusions: This case demonstrates that CGL may represent a feasible and minimally invasive therapeutic option for selected cases of severe laryngomalacia, particularly those involving complex tongue–larynx dynamics.
