Objectives: Laryngomalacia is the dynamic collapse of supraglottic structures during inspiration, leading to a variable degree of airway obstruction. Clinical symptoms appear in the first months of life and are usually mild and resolve by the age of 12-18 months. In severe cases, surgical intervention may be considered. The goal of the study was to review the clinical outcome of pediatric patients who underwent supraglottoplasty for laryngomalacia.
Material and methods: Clinical and demographic data were retrieved from medical records of children diagnosed with laryngomalacia by laryngo-bronchoscopy between 2013 and 2019. Indications, outcome and long-term follow-up were collected from children undergoing surgery.
Results: During the study period, 115 children were diagnosed with laryngomalacia. The median age at diagnosis was 3 months. Synchronous airway lesions were diagnosed in 20% of patients. Ten (8.7%) children underwent surgical treatment because of significant respiratory symptoms and/or failure to thrive. Three of them had comorbidities. All otherwise healthy children had significant respiratory and nutritional improvement after surgery while those with comorbidities had less successful outcomes.
Conclusion: We conclude that in severe cases of laryngomalacia, supraglottoplasty has an important role to play in management. In children with comorbidities, the surgical results may be less successful. Therefore, we recommend that the decision to operate should be individualized, ensuring full disclosure to the family regarding the probable benefit along with the limitations of surgery.
