Comparative Analysis of Various Materials Used for Mastoid Cavity Obliteration in Canal Wall Down Mastoid Surgery.

To study the surgical result and efficacy of different methods of mastoid obliteration with cavity care. This prospective study included 60 patients who had cholesteatoma, conducted in the Department of Ear Nose and Throat (ENT), Institute of Medical Sciences, Banaras Hindu University, Varanasi from July 2015 to July 2017. The mastoid cavity was obliterated with either muscle flap/bone dust/hydroxyapatite. detailed history otoscopic examination was done pre-operatively and follow up were recorded at 1 month and 3 months in postoperative period. 60 patients were included, who underwent canal wall down mastoid surgery. each group muscle flap (group 1), bone dust (group 2) and hydroxyapatite (group 3) included 20 patients, age group 31-40 year with its maximum incidence of 43.3%, Preop PTA value were almost equal in all group but on comparison at 1 month in postoperative period significant improvement was present in group 1 versus 2(0.021) and group 2 versus 3(0.003) but not in group 1 versus 3. Although at 3 month there were significant improvement was present in all groups. The incidence of pain, discharge, giddiness and wax formation were markedly reduced and healing of cavities was early and better in obliterated cavities done by muscle flap and bone dust material as compared to hydroxyapatite cavities, at the end of 3 months. outcome and quality of life was better and almost equal in muscle flap and bone dust material group as compared to hydroxyapatite group.
