Abstract
Chronic cases of retracted tympanic membranes are common conditions which present to the ENT OPD. They are due to a variety of middle ear pathologies and present with decreased hearing in a majority of cases. Pure tone audiometry and tympanometry are the two most common types of audiological evaluations performed in an ENT OPD. They can predict the ossicular chain status and the status of the middle ear as a result of their interpretations. In this study done on 25 patients with chronic retracted tympanic membranes, we established a statistically significant correlation between Grade of Retraction and hearing loss (p= 0.0389) and between tympanometry and pure tone audiometry (p=0.000402).
Keywords: Pure tone audiometry, Tympanometry, Retracted Tympanic Membrane.
