To preserve and improvement of hearing, prevent discharge and recurrence, now a days canal wall down mastoidectomy with reconstruction such as type III tympanoplasty under magnification is a modern advancement in otology.

Objectives: To find out hearing status before mastoidectomy and hearing status after canal wall down mastoidectomy with and without reconstruction.

Methods: Prospectove study done on 3 tertiaty hospitals in Dhaka. Number of patients were 40 who underwent for modified radical mstoidectomy, 20 were with reconstruction and 20 without reconstruction (Type 3 Tympanoplasty)

Results: hearing was deteriorated in most of the cases (60%) of MRM without tympanoplasty. Air Bone (AB) Gap Increased 3.65dB after CWD without reconstruction. Closer of AB gap (9.77 dB) occurred after CWD with reconstruction.
