【摘要】：目的:評估乳突切開術(shù)并一期行聽骨鏈重建的臨床療效。方法:對2008-01-2011-06期間在我科住院行乳突切開術(shù)并一期鈦人工聽骨植入手術(shù)并且有完整隨訪資料的患者139例進(jìn)行回顧分析,其中置入部分聽骨贗復(fù)物(PORP)者91例,置入全聽骨贗復(fù)物(TORP)者48例,隨訪時間為2~5年,純音測聽法(PTA)檢測患者術(shù)前及術(shù)后聽力,比較手術(shù)前后的氣導(dǎo)聽閾(0.5、1.0、2.0、4.0kHz四個頻率氣導(dǎo)之平均值)及氣骨導(dǎo)差(ABG),分析鈦人工聽骨在同期聽骨鏈重建術(shù)的聽力重建效果。術(shù)后ABG≤20dB為聽力提高有效。結(jié)果:PORP植入患者術(shù)前氣導(dǎo)平均聽閾為(53.97±11.32)dB,術(shù)后為(36.80±11.68)dB,平均降低(17.17±5.79)dB;術(shù)前ABG平均為(31.84±6.17)dB,術(shù)后為(15.13±7.22)dB,平均縮小(16.71±5.50)dB;TORP組患者術(shù)前氣導(dǎo)平均聽閾為(58.05±11.35)dB,術(shù)后為(44.53±13.15)dB,平均降低(13.52±7.81)dB;術(shù)前ABG平均為(35.67±5.73)dB,術(shù)后為(21.48±7.01)dB,平均縮小(14.18±7.53)dB;各組術(shù)前術(shù)后的差異均有統(tǒng)計學(xué)意義(P0.01)。PORP組術(shù)后ABG≤20dB者(術(shù)后聽力提高有效)共68例,有效率為74.73%;TORP組術(shù)后ABG≤20dB者共26例,有效率為54.13%;總有效率為68.63%,兩組之間的差異有統(tǒng)計學(xué)意義(P0.05)。結(jié)論:乳突切開術(shù)并同期鈦人工聽骨植入取得了良好的聽力效果,PORP比TORP的聽力改善效果好。
[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，
