Exercise-induced laryngeal obstruction (EILO) consists of exertion-induced laryngeal adduction that constricts the airway and causes dyspnea. Respiratory retraining (i.e., therapy) with a speech-language pathologist (SLP) is the primary treatment for EILO, yet there is limited work describing typical treatment course in adolescents.
What are some clinical procedures and considerations for treating EILO in an adolescent?
This study describes a clinical case of EILO in a 13-year-old female. Case history, self-reported outcomes, and laryngeal imaging findings are reported with reference to current EILO literature.
A 13-year-old female presented to the clinic with a 2-year history of episodic dyspnea. Symptoms included inhalation difficulty, throat tightness, and biphasic stridor. Symptoms were triggered by physical exertion, the scents of cleaners, and high humidity. Symptom onset following trigger exposure was rapid and resolved quickly upon exercise cessation or trigger removal. Symptoms prevented participation in athletic activities and caused emotional distress. Laryngeal imaging revealed arytenoid twitching and paradoxical vocal fold motion upon inhalation. Laryngeal adduction upon inhalation ranged from partial to complete. Respiratory retraining with an SLP was recommended. Following three treatment sessions, the patient demonstrated proficiency with rescue breathing techniques and reported improved EILO symptoms. Posttherapy Dyspnea Index score reflected a 14-point improvement when compared with baseline. Diagnostic procedures, treatment course, and implications are discussed in detail.
This case supports previous study and describes both the nature of EILO and the implications for clinical practice.
运动性喉梗阻（EILO）表现为运动诱发的喉部内收，导致气道狭窄并引起呼吸困难。言语治疗师（SLP）进行的呼吸再训练（即治疗）是EILO的主要治疗方法，但描述青少年典型治疗过程的研究较少。
治疗青少年EILO有哪些临床程序和注意事项？
本研究描述了一名13岁女性EILO的临床病例。参考当前EILO文献报告了病例史、自我报告的结果和喉部影像学检查结果。
一名13岁女性因发作性呼吸困难2年就诊。症状包括吸气困难、喉咙发紧和双相喘鸣。症状由体力活动、清洁剂气味和高湿度引发。接触诱因后症状迅速发作，停止运动或去除诱因后症状迅速缓解。症状妨碍了体育活动的参与并导致情绪困扰。喉部影像学检查显示吸气时杓状软骨抽搐和矛盾性声带运动。吸气时喉部内收程度从部分到完全不等。建议由言语治疗师进行呼吸再训练。经过三次治疗后，患者熟练掌握了急救呼吸技术，并报告EILO症状有所改善。与基线相比，治疗后呼吸困难指数评分提高了14分。详细讨论了诊断程序、治疗过程及意义。
本病例支持先前的研究，并描述了EILO的性质及其对临床实践的意义。
