【摘要】：目的:评估乳突切开术并一期行听骨链重建的临床疗效。方法:对2008-01-2011-06期间在我科住院行乳突切开术并一期钛人工听骨植入手术并且有完整随访资料的患者139例进行回顾分析,其中置入部分听骨赝复物(PORP)者91例,置入全听骨赝复物(TORP)者48例,随访时间为2~5年,纯音测听法(PTA)检测患者术前及术后听力,比较手术前后的气导听阈(0.5、1.0、2.0、4.0kHz四个频率气导之平均值)及气骨导差(ABG),分析钛人工听骨在同期听骨链重建术的听力重建效果。术后ABG≤20dB为听力提高有效。结果:PORP植入患者术前气导平均听阈为(53.97±11.32)dB,术后为(36.80±11.68)dB,平均降低(17.17±5.79)dB;术前ABG平均为(31.84±6.17)dB,术后为(15.13±7.22)dB,平均缩小(16.71±5.50)dB;TORP组患者术前气导平均听阈为(58.05±11.35)dB,术后为(44.53±13.15)dB,平均降低(13.52±7.81)dB;术前ABG平均为(35.67±5.73)dB,术后为(21.48±7.01)dB,平均缩小(14.18±7.53)dB;各组术前术后的差异均有统计学意义(P0.01)。PORP组术后ABG≤20dB者(术后听力提高有效)共68例,有效率为74.73%;TORP组术后ABG≤20dB者共26例,有效率为54.13%;总有效率为68.63%,两组之间的差异有统计学意义(P0.05)。结论:乳突切开术并同期钛人工听骨植入取得了良好的听力效果,PORP比TORP的听力改善效果好。
[Abstract]:Objective: to evaluate the clinical effect of mastoidectomy and ossicular chain reconstruction. A retrospective analysis was made of 139 patients who underwent mastoidectomy and one-stage titanium ossicular implantation in our department during the period from 2008-01-2011-06 and had complete follow-up data. There were 91 cases with partial ossicular prosthesis (PORP) and 48 cases with total ossicular prosthesis (TORP). The follow-up time was 2 ~ 5 years. Pure tone audiometry (PTAA) was used to detect the patients' hearing before and after operation, and to compare the air conduction threshold before and after operation. 4.0kHz mean value of air conduction at four frequencies) and air-bone conductance difference (ABG). Objective: to analyze the effect of titanium artificial ossicular reconstruction in simultaneous ossicular chain reconstruction. ABG 鈮，
