摘　　要：目的比较自体骨及钛金属两种听力重建材料在开放式鼓室成形术后的听力改善状况。方法对2007年10月～2010年5月接受开放式鼓室成形术的21例(21耳)进行回顾性分析,根据听骨链重建材料分为自体骨组和金属钛组,听力统计以0.5,1,2,4 kHz的平均气骨导差值计算。结果自体骨组术后平均气骨导差和术前比较无明显统计学差异,金属钛组术后平均气骨导差较术前缩小(27.5±7.25)dB,两组比较差异有统计学意义。结论在开放式鼓室成形术中,使用金属钛重建听力链的听力改善较自体骨好。Objective To compare the hearing improvement in canal wall down tympanoplasty with autologous bone or titanium prostheses.Methods The data of 21 cases underwent canal wall down tympanoplasty since October 2007 to May 2010 was retrospectively analysed.The patients were divided into 2 groups： autologous bone group and titanium prostheses group.The average postoperative air-bone gaps（A-BG） of four frequencies： 0.5,1,2,4 kHz were measured.Results There was no significant hearing improvement in autologous bone group.The postoperative A-BG in titanium prostheses group significantly reduced by 27.5±7.25 dB.Conclusions The hearing improvement in canal wall down tympanoplasty with titanium prostheses was better than with autologous bone.
