Objective : To compare laryngoscopically observed changes in the larynx during exercise in persons with exercise‐induced laryngomalacia (EIL) with changes in asymptomatic control subjects. Study Design : Clinical study using a standardized exercise protocol. Methods : Subjects exercised on an incremental ergometer: videotaped recordings of the larynx were obtained through the entire exercise; pulmonary function tests were completed before and/or immediately after the exercise. Results : Laryngeal lumen size decreases during exercise in subjects with EIL. Conclusion : Subjects with EIL had a significant decrease in laryngeal lumen size during exercise compared with asymptomatic control subjects.
