Abstract:
Exercise-induced laryngomalacia (EIL) is characterized by inspiratory stridor that is brought on by exercise (i.e. competitive sports) and fails to respond to treatment with bronchodilators (Smith et al., Ann Otol Rhinol Laryngol 1995;104:537-541). During exercise, (1) spirometric flow volume loops show evidence of variable extrathoracic obstruction, and (2) laryngoscopy shows inspiratory prolapse of supraglottic structures with partial glottic obstruction. Only five cases of probable EIL have been reported in the literature (Smith et al., Ann Otol Rhinol Laryngol 1995;104:537-541; Lakin et al., Chest 1984;86:499-501; Bittleman et al., Chest 1994;106:615-616; Bent et al., Ann Otol Rhinol Laryngol 1996;105:169-175; Chemery et al., Rev Mal Respir 2002;19:641-643). Here, a case of laryngomalacia induced by exercise in a previously asymptomatic 10-year-old athlete with a remote history of laryngomalacia in infancy is presented, and a review of previously reported cases is provided.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
