耳甲腔软骨移植修复乙状窦骨壁缺损致搏动性耳鸣的疗效分析

Effect analysis pulsing tinnitus induced by the defect of sigmoid sinus bone wall on ear cartilage transplantation

摘要:

目的 观察使用耳甲腔软骨修复乙状窦骨壁缺损致搏动性耳鸣的疗效。方法 对7例乙状窦骨壁缺损导致的搏动性耳鸣患者行乙状窦骨壁缺损修复及乙状窦缩窄术，首先显露乙状窦骨壁缺损处，将耳甲腔软骨嵌入缺损处进行修复，其中4例患者经乳突入路手术，3例患者经乙状窦后入路手术。结果 7例患者均手术顺利，所有患者手术当天耳鸣消失，无头痛、呕吐、发热、眩晕、听力下降及耳廓畸形等并发症，随访4～36个月，6例痊愈，1例显效。结论 使用耳甲腔软骨修复乙状窦骨壁缺损导致的搏动性耳鸣操作简便、取材方便，无需增加手术切口、创伤小，术后无耳廓畸形、疗效好，耳软骨可塑性强、自体组织无排异反应、易成活，值得临床推广应用。

Abstract:

Objective To observe the effect of repairing pulsing tinnitus caused by bone wall defect of sigmoid sinus with ear cartilage.Methods Seven patients with pulsing tinnitus caused by bone wall defect of sigmoid sinus underwent bone wall defect repair and sigmoid sinus constriction. First, the bone wall defect of the sigmoid sinus was exposed, and the cartilage of the auriculae cavity was inserted into the defect for repair. Four patients underwent mastoid approach and 3 cases underwent retrosigmoid approach.Results All the 7 patients were successfully operated. In all patients, tinnitus disappeared on the day of surgery,and there were no complications such as headache, vomiting, fever, vertigo, hearing loss and auricle deformity, etc. After 4 to 36 months of follow-up, 6 cases were cured and 1 case had obvious effect.Conclusion The use of ear cartilage to repair pulsing tinnitus caused by bone wall defect of sigmoid sinus is easy to operate, convenient to obtain materials, no need to increase surgical incision, small trauma, no postoperative auricle malformation, strong plasticity of ear cartilage, no rejection of autologous tissue, easy to survive.It is worthy of clinical application.
