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

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.
