【摘要】：目的探索先天性中外耳畸形患者耳道再造与鼓室成形术后听力改善情况,为此类患者方案选择提供参考。方法回顾性分析2006年6月~2012年12月我们进行外耳道再造与鼓室成形患者中有术前术后听力的41例(41耳)的情况。结果手术采用听骨链松解41.5%(17/41),Porp植入46.3%(19/41),Torp植入7.3%(3/41),内耳开窗4.9%(2/41)。术前术后0.5k、1k、2k、4k平均气导听阈值分别为(58 d B/53d B),(64 d B/52d B),(73 d B/73d B),(62 d B/46d B).结论听骨链松解与Torp植入术后听力改善不明显,Porp植入和内耳开窗术后听力有明显改善,但未能达到正常听阈水平。
[Abstract]:Objective to explore the hearing improvement after auditory canal reconstruction and tympanoplasty in patients with congenital external ear malformation. Methods from June 2006 to December 2012, 41 cases (41 ears) with pre-and post-operative hearing were retrospectively analyzed in our patients with external auditory canal reconstruction and tympanoplasty. Results the ossicular chain loosening was performed in 41.5% (17 / 41), Porp) of the patients (46.3%) (19 / 41), Torp) in 7.3% (3 / 41), and the inner ear was opened in 4.9% (2 / 41). The mean threshold values of air conduction were (58 d B), (53 d B), (64 d B d 52 d B), (73 d B), (62 d B D 46 d B).) before and after operation 0.5 k, 1 k, 2 k and 4 k, respectively. Conclusion there is no significant improvement in hearing after ossicular chain relaxation and Torp implantation, but there is significant improvement in hearing after Porp implantation and window opening in the inner ear, but the level of normal hearing threshold is not reached.
