Abstract:

In managing patients by canal wall down mastoidectomy, we must ensure good ventilation of the depths of the mastoid cavity, which can be obtained only by a meatoplasty or a correct meatoconchoplasty. After a follow up period of six months duration for 20 cholesteato matous patients managed by C.W.D. mastoidectomy with either meatoplasty or meatochoncoplasty, A/V ratio has a signcant value in relation to the state of the mastoid cavity (dry or wet). Neither area of meatal ┬░perting( A) nor volume of the mastoid cavity (V) is signiftcant separately. Healing process reduces the area of meatoplasty or meatoconchoplasty by about 20%. No significant difference between healing ratio for meatoplasty and that for meatochoncoplasty. Meatoplasty or meatochoncoplasty opening tends to become more circular during healing. Simple scales and some suggestions for practical measuring of proper diameter for meatoplasty and meatochoncoplasty in order to achieve a dry cavity had been done.
