A mastoid cavity resulting from a canal wall down can result in major morbidity for patients due to chronic otorhea and infection, difficulty with hearing aids and vertigo with temperature changes. Mastoid obliteration recreates the normal anatomy to certain extent avoid such morbidity. Few have the studied the quality of life benefited by this procedure. Open cavity mastiodectomy techniques applied for chronic suppurative otitis media with attico antral disease cause some cavity problems, these pts complaints of vertigo in cold weather and during swimming, other problems are difficulty in wearing hearing aids, frequent fungal infections and exuberant wax, and wide meatoplasty which is non aesthetic .and these pts need lifelong otological care for debris that accumulates due to insufficient self cleaning mechanism of mastiodectomy cavities, various obliteration techniques have been recommended to eliminate open cavity problem. Aim & objectives To study surgical results of mastoid cavity obliteration, efficacy of different methods of mastoid obliteration cavity problems and need of cavity care. Materials and methods Retrospective study was carried out in a tertiary care center involving 100 pts from 2015 June – May 2016 having csom with attico antral type of disease who underwent MRM with the cavity obliterated with fibro fatty tissues , cartilage or periosteal flaps . The indication for MRM were patients with extensive cholesteatoma ,with extra cranial complications ,patients with poor compliance for follow up, patients presented with tubo tympanic type, of csom and those with sensorineural hearing loss and intracranial complications were excluded from the study. A detailed history and through ENT examination was done in all patients. Microscopic examination of the affected ears was done to confirm the findings . The lateral oblique view of both mastoids were taken ,HRCT temporal bone was done in these cases where clinical diagnosis is not clear pure tone audiometry and tuning fork tests were done preoperatively and informed written consent was obtained . Results and conclusion In our study the minimum age of the pt was 10 years and maximum age was 55 yrs. Maximum no of pts i.e. 35% in the age group 11-20 yrs followed by 34% in the age group of 21-30 yrs . out of 100 pts male 65 females 35 the male to female ratio1.35;1 65% of the patents belong to rural area 35% belongs to urban area. 100% patients presented with ear discharge ,94% pts presented with hearig loss ,3% of cases presented with facial palsy cholesteatoma was found in all 100 cases , postero superior perforations found in 70% in 30 ears while 20% pts had attic perforation ,30 ears were found to have discharge at 3 months followup 18 ears became dry after medical treatment . At the end of 1 year, well healed cavity with intact graft was seen in 100 cases and 8 cases were advised revision surgery Incidence of discharge, debris,giddiness pain ware reduced in oblitetarating cavities healing was better in obliterating cavity . cavity oblitearing with fibrofatty tissues and flap had better and early epithelisation as compared to cartilage .
