耳内镜下镫骨手术29例疗效分析

Results of endoscopic stapes surgery in 29 cases

目的评估耳内镜下镫骨手术的疗效。方法回顾性分析2020年12月~2023年5月行耳内镜下镫骨底板开窗+人工镫骨植入术的29例患者,术中确诊耳硬化症,收集患者的病史资料并进行汇总分析。结果在研究期间进行44例镫骨手术,其中29例符合纳入标准。所有手术均在耳内镜下进行,术后29例患者骨导听阈无显著性变化(P>0.05);术前气导听阈为(59.91±10.25)dB,术后为(38.92±11.37)dB,显著低于术前(P<0.05);术前气骨导差为(37.37±7.65)dB,术后为(18.71±8.38)dB,显著低于术前(P<0.05)。29例患者无感音神经性聋、面瘫等严重并发症发生,22例患者伴有不同程度眩晕,经对症治疗后缓解。结论耳内镜下镫骨手术是一种安全的手术方式,具有较低的围手术期及术后并发症风险,且能提高耳硬化症患者气导听力。

OBJECTIVE To evaluate the efficacy of otoendoscopic stapes surgery.METHODS From December 2020 to May 2023,a retrospective analysis was performed on 29 patients who underwent otoendoscopic stapes fenestration and artificial stapes implantation were diagnosed with otosclerosis during the operation.The medical history data of the patients were collected and analyzed.RESULTS In the period examined,44 stapes surgical procedures were performed and out of these 29 met the inclusion criteria.All patients were performed under otoendoscopy.There was no significant change in bone conduction threshold(P>0.05),but the average air conduction threshold improved from the preoperative(59.91±10.25)dB HL to(38.92±11.37)dB HL with air-bone gap reduced from the preoperative(37.37±7.65)dB HL to(18.71±8.38)dB HL(P<0.05).There were no serious complications such as sensorineural hearing loss and facial paralysis,but 22 patients were accompanied by varying degrees of vertigo,which were relieved after symptomatic treatment.CONCLUSION Endoscopic stapes surgery is a safe procedure with a low risk of peri-or postoperative complications,and can improve the air conduction hearing of otosclerosis patients.
