Comparative Study of Management of Attico-antral CSOM by Conventional Mastoidectomy with Inside Out Technique

This prospective study was undertaken to compare the different aspects of inside out and conventional mastoidectomy techniques in attico-antral type of chronic suppurative otitis media. 100 cases of unsafe ear selected in this study were divided in 2 groups-(1) Group A-50 patients operated by conventional technique of canal wall down mastoidectomy. (2) Group B-50 patients operated by inside out technique of canal wall down mastoidectomy. The patients in our series were regularly followed to assess the condition of the postoperative cavity for three months. Post operative results were better by inside out as compared to conventional technique of mastoidectomy. Hearing and air-bone gap improvement was more in patients operated by inside out mastoidectomy. Less number of patients suffered with post operative residual disease like cholesteatoma, granulation, discharge and residual perforation as compared to conventional mastoidectomy.
