Exercise-induced laryngomalacia (EIL) is characterized by severe dyspnea, stridor, and mild wheezing unresponsive to prophylactic treatment with beta-agonists and cromolyn sodium. Symptoms develop with extreme exertion, but resolve quickly as the degree of exercise is decreased. Diagnosis requires flexible fiberoptic laryngoscopy before, during, and after exercise. If the diagnosis of EIL is confirmed by laryngoscopy during maximal exercise, laser epiglottoplasty is effective in alleviating symptoms and improving the airway. However, because symptoms develop only during maximal exertion, EIL is unlikely to produce symptoms or functional disability in persons who lead relatively sedentary lives.
运动诱发性喉软化症（EIL）的特征为严重呼吸困难、喘鸣和轻度喘息，对β受体激动剂和色甘酸钠预防性治疗无反应。症状在剧烈运动时出现，但随着运动程度降低会迅速缓解。诊断需要在运动前、运动期间和运动后进行可弯曲纤维喉镜检查。如果在最大运动量时喉镜检查确诊为EIL，激光会厌成形术可有效缓解症状并改善气道。然而，由于症状仅在最大运动量时出现，EIL在生活相对 sedentary 的人群中不太可能产生症状或功能残疾。 （注：sedentary 这个词有误，推测可能是sedentary，意为久坐不动的，这里暂且按“久坐不动的”翻译）
