晚期慢性粘连性中耳炎常伴听力严重损害。许多学者对慢性粘连性中耳炎的发病机制、病理、临床表现和治疗进行了广泛的研究,报告最多的是中耳完全塌陷,有些病例合并胆脂瘤和听骨链中断。本文粘连性中耳炎是指鼓膜完整但变得十分菲薄,部分或全部粘连于中耳内壁,鼓膜活动完全或部分消失。部分粘连的病例,中耳内可能有积液。本文的目的是阐明在不可逆的粘连病变形成之前,能否进行有效的耳科手术治疗。 20例儿童,男9女11,年龄4～15岁,手术21耳。16例以前插过通气管。手术经外耳道进行,造成鼓膜外耳道皮瓣,检查中耳粘膜状态、中耳积液、听骨链的连续性和活动性,此后将硅橡胶
Late chronic adhesive otitis media often accompanied by severe hearing impairment. Many scholars have studied the pathogenesis, pathology, clinical manifestation and treatment of chronic adhesive otitis media. The most reported are the complete collapse of the middle ear, and some cases with cholesteatoma and ossicular chain disruption. Adhesive otitis media in this article refers to the integrity of the tympanic membrane but become very meager, some or all of the adhesion in the middle ear wall, tympanic membrane activity completely or partially disappear. Some cases of adhesion, the middle ear may have fluid. The purpose of this article is to elucidate whether effective otological surgery can be performed before irreversible adhesions develop. 20 cases of children, 9 men and 11 women, aged 4 to 15 years old, surgery 21 ears. Sixteen patients had previously inserted the ventilation tube. Surgical operation of the external auditory canal, resulting in tympanic membrane outer ear flap, check the mucosal status of the middle ear, middle ear effusion, continuity and mobility of the ossicular chain, then silicone rubber
