ABSTRACT
OBJECTIVE:
Adult-onset laryngomalacia is a rare clinical entity that has been infrequently reported. This study aims to evaluate the clinical presentation, diagnosis, and management of adult-onset laryngomalacia through literature review and report of a case.METHODS:
PubMed and Google Scholar databases were queried for articles published from 1960 to 2019 including only patients aged 18 years and older. Included keywords were 'laryngomalacia', 'adult laryngomalacia', 'acquired laryngomalacia', 'idiopathic laryngomalacia', 'laryngeal obstruction', 'floppy epiglottis', 'floppy epiglottis', and 'epiglottis prolapse'. Data extracted from literature included clinical presentation, diagnostic workup, surgical management, and follow-up care. SOURCES PubMed and Google Scholar.RESULTS:
A total of 21 articles reported 41 cases of adult-onset laryngomalacia. Within these cases, 5 etiologies were identified neurologic (n = 14), exercise-induced (n = 9), post-operative (n = 7), idiopathic (n = 7), and age-related (n = 4) laryngomalacia. Anterior prolapse of arytenoids and aryepiglottic folds was the most common laryngoscopic finding (n = 21), followed by posterior epiglottic prolapse (n = 20). Management included supraglottoplasty (n = 14), epiglottidectomy (n = 8) or epiglottopexy (n = 2). Neurologic etiology required tracheotomy more often than the other etiologies (n = 5, 36% vs. 15%). Three patients were managed expectantly without surgical intervention and reported symptom resolution.CONCLUSION:
Adult laryngomalacia is a rare diagnosis comprising a spectrum of disease. This diagnosis may be overlooked, but association with neurologic injury or trauma should encourage consideration. In comparison to pediatric laryngomalacia, patients often require surgical intervention. Surgical decision is based on the direction of supraglottic collapse, where supraglottoplasty and partial epiglottidectomy are effective interventions. LEVEL OF EVIDENCE N/A.Palavras-chave
