【摘要】：目的探讨自体乳突骨皮质应用于开放式鼓室成形术的疗效。方法将40例慢性化脓性中耳炎患者随机分为实验组和对照组,每组20例,实验组在常规开放式鼓室成形术基础上以自体乳突骨皮质行上鼓室重建手术及乳突腔填充术,对照组则仅完成常规开放式鼓室成形术,随访1年,比较两组术后干耳及听力改善情况。结果术后1年实验组干耳率100%,高于对照组(70.0%,14/20),两组听力较术前明显改善(P0.01),但术后6个月时,实验组纯音听力提高值(23.42±90dB)高于对照组(8.43±0.04dB)。结论自体乳突骨皮质应用于开放式鼓室成形术中上鼓室重建及乳突腔填充治疗慢性化脓性中耳炎,术后干耳率高,听力提高效果好。
[Abstract]:Objective to investigate the effect of autologous mastoid bone cortex in open tympanoplasty. Methods 40 patients with chronic suppurative otitis media were randomly divided into experimental group (n = 20) and control group (n = 20). In the control group, only routine open tympanoplasty was completed, followed up for one year, and the improvement of dry ear and hearing was compared between the two groups. Results 1 year after operation, the dry ear rate of the experimental group was 100%, which was higher than that of the control group. The hearing of the two groups was significantly improved than that of the preoperation (P 0.01), but at 6 months after operation, the improvement of pure tone hearing in the experimental group was 23.42 卤90 dB, which was higher than that in the control group (8.43 卤0.04 dB). Conclusion the autologous mastoid bone cortex was used in the treatment of chronic suppurative otitis media with open tympanoplasty and mastoid cavity filling. The dry ear rate was high and the hearing was improved.
