【摘要】：目的研究鈦質(zhì)人工聽骨植入在一期鼓室成形術(shù)中的療效。方法對3 1例用鈦質(zhì)人工聽骨行一期鼓室成形術(shù)的患者,隨訪3-6個月。通過計算術(shù)前術(shù)后純音測聽得出氣骨導(dǎo)閾值的平均值,比較手術(shù)后氣導(dǎo)的恢復(fù)情況和手術(shù)前后的氣骨導(dǎo)差。結(jié)果 3 1例患者術(shù)后鼓膜愈合良好,未見人工聽骨排異反應(yīng),及聽骨脫出,有1例在術(shù)后2個月時發(fā)生感染。31耳術(shù)前氣導(dǎo)聽力30.00~88.75dB,平均為(59.27±15.67)dB,術(shù)后氣導(dǎo)平均聽力為(43.10±14.64)dB,與術(shù)前相比,差異有統(tǒng)計學(xué)意義(P0.05)。術(shù)前骨導(dǎo)聽力為10.00~43.75dB,平均為(23.06±9.18)dB,術(shù)后骨導(dǎo)平均聽力為(22.82±7.49)dB,與術(shù)前相比,差異無統(tǒng)計學(xué)意義(P0.05)。術(shù)前氣骨導(dǎo)差(ABG)為11.25~62..5dB,平均為(36.21±11.88)dB,術(shù)后ABG平均為(19.40±12.92)dB,二者比較,差異有統(tǒng)計學(xué)意義(p0.05)。術(shù)后ABG≤20dB且ABG較術(shù)前縮小15dB為聽力提高有效,共有13耳,有效率為41.94%(13/31)。結(jié)論鈦質(zhì)人工聽骨植入在一期鼓室成形術(shù)中可以取得滿意的聽力效果,術(shù)后并發(fā)癥少,排除率低,在有聽骨鏈破壞行Ⅰ期鼓室成形術(shù)中值得推廣應(yīng)用。
[Abstract]:Objective to study the effect of titanium artificial ossicular implantation in one-stage tympanoplasty. Methods 31 cases of primary tympanoplasty with titanium artificial ossicle were followed up for 3-6 months. The mean value of air-bone conduction threshold was obtained by preoperation and postoperative pure tone audiometry, and the recovery of air conduction and the difference of air-bone conductance before and after operation were compared. Results the tympanic membrane healed well in 31 patients after operation, and there was no artificial ossicular rejection and ossicular prolapse. There was infection in 1 case 2 months after operation. 31 ears had air conduction hearing 30.008. 75 dB before operation, with an average of (59. 27 鹵15. 67) dB,. The average hearing conduction after operation was (43.10 鹵14.64) dB, which was significantly higher than that before operation (P0.05). Preoperative bone conduction hearing was 43.75 dB with an average of (23.06 鹵9.18) dB, and the average hearing conduction was (22.82 鹵7.49) dB,. There was no significant difference between the two groups (P0.05). The preoperative difference of air-bone conductance (ABG) was 11.25 鹵62..5dB, the average ABG was (36.21 鹵11.88) dB, the average ABG was (19.40 鹵12.92) dB, the difference was statistically significant (p0.05). After operation, ABG 鈮，
