A case report demonstrates improved airway function through glosso-larynx correction in a severely symptomatic infant, suggesting a new treatment option.
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.
