Abstract

A canal wall down mastoidectomy (CWDM) is an effective technique for eradication of chronic suppurative otitis media (atticoantral disease) or cholesteatomas. A retrospective study was conducted at R.D. Gardi Medical college between 2015 and 2017 to evaluate the outcome of CWDM for patients with atticoantral type of CSOM. All new cases of MRM/RM which fulfilled the selection criteria were reviewed. The main outcome measures were the hearing outcome and status of dry ear postoperatively. 60 patients of CWDM (32 male, 28 female) were included for analysis. All patients in our study were between 7 and 52 years with mean age 28.38 years. The ossicular chain was eroded in all the cases. Improvement in Air–Bone–Gap was seen in 11 (18.33%), no change in 38 (63.33%) and 11 (18.33%) had deteriorated. In post operative outcome study of our 60 patients, 76.66% of the patients had dry healed cavity and non healed cavity was found to be in 23.33% of the patients. On analysis of data and comparison with other studies it was found that there are three important factors which influence hearing results and the outcome of surgery—status of ossicular chain, presence or absence of cholesteatoma, recurrence or residual disease.
