作者们对7～16岁鼓膜穿孔已干耳三个月以上的患儿99例(男54,女55)计114耳采取耳后径路及颞筋膜移植修复鼓膜,有9例并作听骨链成形术。随访1年后,按年龄分组的手术成功率为67～100%,平均为81%。一侧穿孔的成功率为87%,两侧穿孔的成功率为64%,两者有显著差异(P<0.01)。失败病例多在术后6个月内,年岁小的较多。随访三年后,成功率降至72%(40～100%),而14～16岁患儿的有效率没有下降,表明成功率的稳定性增加与年龄有关。语频听力
The authors evaluated the tympanic membrane in 99 cases (54 males and 55 females) of 114 children aged 7 to 16 years who had perforation of the tympanic membrane of the tympanic membrane for more than three months and received retro-orotomy and temporal fascia transplantation. Nine patients Chain angioplasty. One year after follow-up, the success rate of surgery grouped by age was 67-100% with an average of 81%. The success rate of perforation on one side was 87%, and the success rate of perforation on both sides was 64% (P <0.01). Failures in more cases within 6 months after surgery, younger age more. After three years of follow-up, the success rate dropped to 72% (40-100%), while the effectiveness of children aged 14 to 16 years did not decrease, indicating that the stability of the success rate increases with age.
