耳后双蒂肌骨膜瓣在大乳突腔填塞中的应用

目的探讨耳后双蒂肌骨膜瓣在乳突根治术中，填塞乳突腔对干耳及听力疗效的观察。方法对慢性中耳炎患者行乳突根治术、鼓室成形术和耳甲腔成形术78例（耳）中，进行耳后双蒂肌骨膜瓣填塞乳突腔。结果78例患者中，患耳干耳时间缩短至10～15天，58例听力较术前提高（17．2±4．9）dB。结论耳后双蒂肌骨膜瓣填塞对术后乳突腔的迅速上皮化、易干耳、重建外耳道后壁以及术后听力的提高具有一定的疗效。

Study of using postaural bipedicle musculoperiosteal flap in mastoid obliteration

OBJECTIVE To explore the dry ears and improving the auditory level of postaural bipedicle musculo-periosteal flap to obliterate the mastoid cavity. METHODS 78 cases （ears） of chronic otitis media were treated with radical mastoidectomy, open-ended tympanoplasty and conchaplasty, and received mastoid plombabge by postaural bipedicle musculo-periosteal flap. RESULTS In 78 cases （ears） , the time of dry ears were reduced to 10 or 15 days and the auditory level in 58 ears was impoved （17.2±4.9） dB after treatment. CONCLUSION The surgery with postaural bipedicle musculo-periosteal flap to plombabge the mastoid cavity can achieve the epithelization in the operation cavity more quickly, achieve a short duration to dry ear shortly and improve the auditory level.
