目的 :在传统乳突根治术的基础上 ,探讨保留部分外耳道后壁鼓室成形术的方法 ,以期提高化脓性中耳乳突炎病人的干耳率 ,提高听力的可能性。方法 :对 2 6例 (2 9耳 )化脓性中耳乳突炎患者进行乳突根治术 ,保留部分外耳道后上壁 ,一期重建中耳传音结构。结果 :2 6例 (2 9耳 )术后 8个月～ 2 4个月随访 ,术后干耳并听力提高达实用听力水平 (2 5d B以上 ) 2 6耳 ,治愈率达 89.7% ,复发 3耳 ,复发率为10 .3%。结论 :对于耳咽管功能良好的化脓性中耳乳突炎病人在彻底清除乳突中耳病变的同时 ,行保留部分外耳道后壁及鼓环的鼓室成形术 ,更接近中耳生理结构 ,即清除炎性病变 ,又提高听力 ,值得推广。
OBJECTIVE: To explore the method of preserving the posterior wall tympanoplasty of external auditory canal on the basis of traditional radical mastoidectomy in order to improve the dry ear rate and improve the hearing ability of patients with suppurative otitis media. Methods: Twenty-six cases (29 ears) of purulent otitis media were treated by radical mastoidectomy. Some upper extremities of the external auditory canal were reserved and the middle ear acoustic structures were reconstructed. Results: Twenty-six cases (29 ears) were followed up for 8 months to 24 months after operation. The postoperative dry ear and hearing increased up to practical hearing level (25 days or more) 26 ears, the cure rate was 89.7% 3 ears, the recurrence rate was 10.3%. Conclusion: For patients with purulent otitis media with otosympathetic suppository otitis media, tympanoplasty of the posterior wall of the external auditory canal and the tympanic ring may be performed more closely to the middle ear physiology, Sexually transmitted diseases, but also improve hearing, it is worth promoting.
