Laryngomalacia is usually a benign condition which occurs soon after birth, and is resolved by 2 years of age. A 12-year-old female, with a history of nasal allergy, had complained of inspiratory stridor and cough. Laryngoscopy revealed a flaccidity of all the supraglottic structures. The arytenoids and aryepiglottic folds were fluttering during inspiration. The stridor was improved after resecting the excess tissue with a CO2 laser. A barking cough appeared about 10 days after the operation and placebos were effected to it. We suggest that she had a tendency to inspiratory laryngeal collapse and that her symptoms might have been triggered by allergic and/or psychological factors.

過去10年間に長崎大学耳鼻咽喉科を受診し, 蝸電図あるいは聴性脳幹反応Auditory Brainstem Response (ABR) を施行して詐聴と診断し得た82名について検討を行った。 昭和54-58年の前期5年間と昭和59-63年の後期5年間を比較すると, 症例数は約2倍, 当科にて蝸電図またはABRを行った全症例に対する比も約1.5倍と増加しており, 70歳以上の高齢者症例も増加していた。
