目的 探讨外植法鼓膜成形术的疗效。方法 采用外植法鼓膜成形术对 2 5 7例 (32 7耳 )慢性单纯型化脓性中耳炎病人行鼓膜成形术 ,术后 3个月必须按期到医院复查 ,平均随访时间 6 .6年。结果 鼓膜穿孔愈合318耳 ,再穿孔 9耳 ,愈合率为 97.2 5 % ,修补的鼓膜具有良好的外形 ,术后 3个月的定期复查对提高疗效至关重要。术后 0 .5kHz ,1kHz ,2kHz纯音的平均听阈降低 15～ 2 0dB者 12 5耳 ,听阈降低 2 1～ 30dB者 16 2耳 ,听阈降低 31dB以上者 2 5耳 ,无变化 15耳。结论 外植法鼓膜修补术是修补鼓膜穿孔较为理想的方法之一
Objective To investigate the curative effect of eardrum tympanoplasty. Methods Twenty - seven cases (32.7 ears) of chronic simple suppurative otitis media were treated with eardrum tympanoplasty by eardrum tympanoplasty. Three months after operation, they must go to hospital for follow - up. The average follow - up time was 6.6 years. Results The tympanic membrane perforation healed 318 ears, and then perforated 9 ears, the healing rate was 97.2 5%, repaired the tympanic membrane has a good shape, regular 3 months after the review is essential to improve the efficacy. The average hearing threshold at 0 .5kHz, 1kHz and 2kHz postoperatively decreased 15 ~ 20dB, 125 ears and 21 ~ 30dB hearing threshold decreased by 21 ~ 30dB, while hearing threshold decreased by 31dB or more. Conclusion The method of repairing tympanic membrane perforation is one of the ideal methods to repair tympanic membrane perforation
