Chronic suppurative otitis media is the commonest cause of hearing loss. The deafness caused by chronic suppurative otitis media of safe type was usually considered to be purely of conductive type. With this background present study was planned to study safe and unsafe CSOM with sensori neural hearing loss with Pathophysiological study.One hundred patients of chronic suppurative otitis media with sensori neural hearing loss, either alone or more commonly, with mixed loss were studied in this series. The patients were carefully selected after proper history and careful examination to exclude the above mentioned criteria to rule out the other possible causes of sensori neural loss. Type of pathology in each of these ears was the main factor taken into consideration. Age group and duration of illness were also considered.In our study, 14% cases of unsafe chronic suppurative otitis media were found to be associated with labyrinthine fistula. This proved to be the commonest cause of sensori neural component in unsafe chronic suppurative otitis media followed by granulation over oval window (8%) and cholesteatoma extending to round window in 4 % of cases.In our study, 14% cases of unsafe chronic suppurative otitis media were found to be associated with labyrinthine fistula. This proved to be the commonest cause of sensori neural component in unsafe chronic suppurative otitis media.
