本文旨在明确听力、鼓室功能测试能否区分三种有渗出液的中耳炎(粘液性、化脓性、浆液性中耳炎)及临床表现明显而无渗出液的中耳炎。作者对129例12岁以下、中耳渗出持续3个月以上的患儿进行了研究。对其处置包括鼓膜穿刺和鼓膜切开置管术,术前一周内测试患儿的纯音听力和鼓室功能曲线。气骨导纯音阈取250～4000赫的平均值,以气导阈、骨导阈及气骨导差对四
This paper aims to clarify hearing, tympanometry can distinguish between three kinds of exudate otitis media (mucinous, purulent, serous otitis media) and clinical manifestations of effusion without otitis media. The authors studied 129 children under 12 years of age with middle ear exudation for more than 3 months. Its treatment includes tympanic membrane puncture and tympanotomy incision catheterization test within one week before the pure tone hearing and tympanic function curve. Gracilaria pure tone threshold 250 to 4000 Hz average, with air conduction threshold, bone conduction threshold and air conduction difference to the four
