摘要
目的:评价钛质听小骨假体在完壁式乳突根治鼓室成形术(ICWT)后的疗效。方法:对31例使用钛质听小骨假体进行ICWT的患者进行评估,按听骨类型分为部分听骨赝复物(PORP)组和全听骨赝复物(TORP)组,对2组患者术后1年的听力情况和并发症发生率进行分析。结果:手术总有效率为(气骨导差≤20dB)87.1%,术后平均增益PROP组为(19.38±10.08)dB,TORP组为(15.15±10.15)dB;术后气骨导差PROP组为(12.29±4.40)dB,TORP组为(15.48±6.26)dB;2组术后气骨导差及气导增益表现均差异无统计学意义,但在低频区(0.5kHz)气骨导差存在统计学差异;未见听骨排出发生。结论:钛质听小骨在ICWT能够取得满意的听力结果,成功率高于其他综合文献的报告。但2种类型听骨比较差异无统计学意义,术后并发症发生率低,有待长期的随访。
Objective：To evaluate the effects of intact canal wall tympanoplasty with mastoidectomy（ICWT）with titanium ossicular prostheses.Method：A retrospective review was performed on 31 patients who underwent ICWT from 2008 to 2011.Patients＇ postoperative hearing results and complication rates were evaluated based on different types of ossicular prosthesis： partial ossicular replacement prosthesis（PORP）,total ossicular replacement prosthesis（TORP）.Result：The total effectiveness was 87.1%.No prosthesis was extruded.There was no significant difference in postoperative hearing results（average postoperative gain and ABG） between the two prostheses.In the low frequency（0.5 kHz）,singnificant difference in ABG was found.Conclusion：No significant difference in postoperative hearing results was found between PORP and TORP,which could be useful materials for tympanoplasty and obviously improve the hearing of otitis media patients after operation.As for the low incidence of postoperative complications in our short-term study,long-term follow-up visit is necessary.
