粘连性中耳炎是一种非化脓性中耳炎,以鼓室粘连和纤维化为其主要特征。由于咽鼓管功能障碍,鼓室腔隙逐渐消失,听力下降;钙化、脂肪变性和瘢痕组织亦妨碍鼓膜及听小骨的活动。作者对接受鼓室成形术治疗的55例粘连性中耳炎患者进行随访,平均随访时间为7.3年。手术过程为:分离鼓室粘连,清除病变后使用硅橡胶覆盖鼓岬,其范围自咽鼓管至卵圆窗。听骨链若有破坏,则用自身听骨或乳突骨修复。有些病例作鼓膜导管引流,还有32耳同时行单纯乳突切除术。术后,鼓膜完整活动者19耳(34%);鼓膜继续粘连30耳(55%);鼓膜穿孔6耳(11%),其中5耳干燥,1耳流脓;全聋1耳;继发胆瘤1耳。骨气导差平均提高3.6 dB;13耳(24%)
Adhesive otitis media is a non-suppurative otitis media, with tympanic adhesions and fibrosis as its main features. Due to eustachian tube dysfunction, the tympanic cavity gradually disappeared, hearing loss; calcification, steatosis and scar tissue also hinder the tympanic membrane and ossicle activity. The authors followed up 55 patients with otitis media with tympanoplasty who were followed up for an average of 7.3 years. Surgical procedures for the separation of tympanic adhesions, removal of lesions using silicone rubber covered promontory promontory, ranging from the eustachian tube to the oval window. If the damage to the ossicular chain, use their own bone or mastoid bone repair. In some cases tympanic membrane drainage, there are 32 ears at the same time simple mastoid resection. After operation, 19 (34%) of the total eardrums were active; the eardrum continued to attach to 30 ears (55%); the tympanic membrane had 6 ears (11%) with 5 ears dry and 1 ear abscess; Cholelithiasis 1 ear. Osseous conduction improved by an average of 3.6 dB; 13 ears (24%)
