摘要(Abstract):

目的探讨骨粉填塞用于开放式改良乳突根治术的可行性和临床疗效。方法回顾性分析北京协和医院2013年10月至2014年2月收治的12例因慢性化脓性中耳炎行开放式改良乳突根治术并采用骨粉行乳突腔填塞患者的临床资料。观察术后鼓膜和乳突腔形态,并对术腔完全上皮化时间和术后听力改善情况进行统计学分析。结果 12例患者均干耳;手术后鼓膜形态接近正常,乳突腔体积明显缩小;完全上皮化时间平均29.9 d。8例行人工听骨听力重建患者平均听力提高(11.7±1.8)dB,听力重建效果好。结论开放式改良乳突根治术术腔采用骨粉填塞法简便易行,术腔表面光滑,愈合时间缩短,鼓膜形态良好,听力重建效果佳。
Objective To investigate the clinical outcome of bone pate for mastoid obliteration after canal wall down mastoidectomy. Methods The clinical data of 12 patients who had undergone canal wall down mastoidectomy followed by bone pate obliteration in Peking Union Medical College Hospital from October 2013 to February 2014 were retrospectively analyzed. The post-operative morphologies of tympanic membranes and mastoid cavities were observed,and the complete reepithelialization time and improvement of hearing were analyzed.Results The mastoid cavities were completely reepithelialized in all 12 patients. The morphologies of tympanic membranes were nearly normal. The volumes of mastoid cavities were significantly reduced. The mean time of complete reepithelialization was 29. 9 days. The air-bone gap value increased by( 11. 7 ± 1. 8) dB after the operation in 8 patients who had undergone hearing reconstruction. Conclusions Mastoid obliteration with bone pate after canal wall down mastoidectomy is a simple and convenient procedure that can easily make the mastoid cavity be well-shaped and reepithelialized,shorten the healing time,and achieve good hearing outcome.
