目的:探讨锤骨-前庭桥接技术在治疗并发锤砧传声功能障碍的以耳硬化为主体的镫骨病变患者中的可行性、安全性及有效性。方法:对2005年3月~2007年3月78例镫骨手术中采用锤骨-前庭桥接技术的锤镫手术6例进行回顾性分析,就手术步骤、术中发现及术后眩晕加以讨论,并比较手术前后的纯音测听结果。结果:6例均存在镫骨底板固定,其中2例并发可能炎症参与的锤砧、砧镫关节变形、僵硬、固定,1例并发锤砧关节周围局灶性鼓室硬化,另2例并发锤骨前上韧带固定,最后1例为手术操作意外导致锤砧关节脱位。6例术后均无明显眩晕,0.5、1.0、2.0及4.0 kHz频率范围的平均气骨导差均<10 dB,未发现4.0 kHz切迹。随访3个月~2年。结论:以锤骨-前庭桥接技术为基础的锤镫手术对于不同原因所致的并发锤砧传声功能障碍的耳硬化是一种安全、有效的治疗方法。
Objective: To investigate the feasibility, safety and efficacy of masticatory-vestibular bridging in the treatment of otosclerosis patients with otosclerosis as the main dysfunction of sound transmission. Methods: A retrospective analysis was performed on 6 cases of hammerhead operation using bone-vestibular bridging technique in 78 cases of tarsal surgery from March 2005 to March 2007. The surgical procedures, intraoperative findings and postoperative vertigo were discussed. And compared before and after the pure tone audiometry results. Results: There were 6 cases of stapes fixation, including 2 cases of anvil, anvil and ankle joint deformity, stiff and fixed, one case complicated with tympanosclerosis around the anvil and the other two cases complicated with mallet Anterior ligament fixation, the last one case of surgical anomalies lead to ankle joint dislocation. No postoperative vertigo was found in all 6 cases. Mean airway conduction errors were all <10 dB at 0.5, 1.0, 2.0 and 4.0 kHz, and no notch at 4.0 kHz was found. Follow-up 3 months to 2 years. CONCLUSION: Hammer-bladder surgery based on mastic-vestibular bridging technique is a safe and effective method for the treatment of otosclerosis caused by different causes of anacoustic aneurysm dysfunction.
