An association of sensorineural hearing loss in mucosal type of chronic suppurative otitis media

Background Chronic suppurative otitis media of mucosal variety is one of the most common cause of conductive hearing loss worldwide. Sensorinueral hearing loss is rare but well established complication of chronic suppurative otitis media of squamosal variety. We made an attempt to view the sensorineural hearing loss in mucosal type of chronic otitis media and keeping objectives and aims as follows occurrence of sensorinueral hearing loss in mucosal type of chronic suppurative otitis media; relation of sensorinueral component with age, gender and duration in mucosal type of chronic suppurative otitis media.

Methods A total of 105 cases of mucosal type of CSOM were studied retrospectively for the pattern of hearing impairement on the basis of pure tone audiogram in a Tertiary care hospital. Relation 0f sensorinueral hearing loss with with age, gender and duration in mucosal type of CSOM is compared and tabulated with various studies.

Results Out of total 105 cases of CSOM of mucosal variety 30 (28.57%) had sensorinueral hearing loss affecting 13 males and 17 females with males to females ratio of 1:1.3.Mean bone conduction thresholds in males at 1 kh, 2 kh and 4 kh is 30.38%, 38.46% and 46.15% respectively and Mean bone conduction thresholds in females at 1 kh, 2 kh and 4 kh is 30.88%, 35% and 44.41% respectively.

Conclusions Significant sensorinueral hearing loss was seen in our study. Age, gender and duration didn’t have any impact on degree of sensorinueral hearing loss.
