Various Tympanic membrane conditions are known to affect the stiffness and mass component of the ear differently affecting hearing level. Thus the present study was conducted to find out the correlation of tympanic membrane abnormalities with the audiometric and tympanometric findings.

Material & Methods: All the patients reporting to the E.N.T Deptt. in the age range of 11-70 years with ear problems were examined. Total 111 ears were taken in the study. Inclusion criteria: The patients with tympanic membrane abnormalities e.g myringitis, Myringosclerosis, tympanic membrane atrophy and retracted tympanic membrane, Granular TM were examined under microscope and audiometery and tympanometry was done.

Results: In the present study the most common Tympanic membrane abnormality seen was Retraction. Among which the Grade I retraction was the commonest. Second most common was Tympaosclerosis. It was noticed that among retraction, type A graph was commonest .In tympanosclerotic patch As ,atrophy Ad was commonest while in SOM Cases B type was commonest .There was significant correlation between hearing loss and Grade of retraction but no significant correlation was observed in Pure tone audiometry and typanometry.

Conclusion: In our study we observed that TM abnormality is not always associated with significant audiological findings.
