目的探讨耳内镜在鼓膜修补术中的应用价值及耳内镜下鼓膜修补术的疗效。方法选用0°直径2.7mm耳内镜及Olympus内镜摄像、显像系统,对23例慢性单纯型中耳炎及外伤性鼓膜穿孔患者,在耳内镜直视下应用自体颞肌筋膜以内植法经穿孔将筋膜植入、铺平,行鼓膜修补术。结果 23例患者随访6个月以上,治愈21例,占91.3%;有效1例,占4.3%;无效1例,占4.3%。半年后听力测试语言频率气骨导差在0～15 dB之间,均值缩小约为8dB。语言频率提高(20±5.1)dBHL者13例,(15±4.8)dBHL者7例,(10±3.2)dBHL者2例,1例听力无变化。结论耳内镜下鼓膜修补术疗效满意,是一种安全可靠、操作及要求较为简单的手术方式,临床有较高的应用价值。
Objective To investigate the value of endoscopic surgery in tympanic membrane repair and the effect of tympanic membrane repair under endoscopic surgery. Methods 0 ° diameter 2.7mm endoscope and Olympus endoscopic imaging and imaging system were selected. Twenty-three patients with chronic simple otitis media and traumatic tympanic membrane perforation were enrolled in this study. The perforation will be fascia implantation, paving, tympanic membrane repair. Results 23 patients were followed up for 6 months or more, 21 cases were cured, accounting for 91.3%; 1 was effective, accounting for 4.3%; 1 was ineffective, accounting for 4.3%. Six months after the hearing test, the frequency of air-bone conduction difference between 0 ~ 15 dB, the average reduction of about 8dB. There were 13 cases with speech enhancement of (20 ± 5.1) dBHL, 7 cases (15 ± 4.8) dBHL, and 2 cases (10 ± 3.2) dBHL with no change in hearing. Conclusions Eardrum repair of tympanic membrane is satisfactory, which is safe, reliable and easy to operate and requires. It has high clinical value.
