【摘要】：目的研究钛质人工听骨植入在一期鼓室成形术中的疗效。方法对3 1例用钛质人工听骨行一期鼓室成形术的患者,随访3-6个月。通过计算术前术后纯音测听得出气骨导阈值的平均值,比较手术后气导的恢复情况和手术前后的气骨导差。结果 3 1例患者术后鼓膜愈合良好,未见人工听骨排异反应,及听骨脱出,有1例在术后2个月时发生感染。31耳术前气导听力30.00~88.75dB,平均为(59.27±15.67)dB,术后气导平均听力为(43.10±14.64)dB,与术前相比,差异有统计学意义(P0.05)。术前骨导听力为10.00~43.75dB,平均为(23.06±9.18)dB,术后骨导平均听力为(22.82±7.49)dB,与术前相比,差异无统计学意义(P0.05)。术前气骨导差(ABG)为11.25~62..5dB,平均为(36.21±11.88)dB,术后ABG平均为(19.40±12.92)dB,二者比较,差异有统计学意义(p0.05)。术后ABG≤20dB且ABG较术前缩小15dB为听力提高有效,共有13耳,有效率为41.94%(13/31)。结论钛质人工听骨植入在一期鼓室成形术中可以取得满意的听力效果,术后并发症少,排除率低,在有听骨链破坏行Ⅰ期鼓室成形术中值得推广应用。
[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 卤15. 67) dB,. The average hearing conduction after operation was (43.10 卤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 卤9.18) dB, and the average hearing conduction was (22.82 卤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 卤62..5dB, the average ABG was (36.21 卤11.88) dB, the average ABG was (19.40 卤12.92) dB, the difference was statistically significant (p0.05). After operation, ABG 鈮，
