ABSTRACT

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.
