BACKGROUND Chronic Otitis Media is a permanent abnormality of the pars tensa or flaccida, most likely a result of earlier acute otitis media, negative middle ear pressure or otitis media with effusion. METHODS In our study, we evaluated the hearing status by means of a Pure Tone Audiometry in patients with inactive mucosal chronic otitis media undergoing myringoplasty with a temporalis fascia underlay procedure. RESULTS At the end of the study, the mean improvement in the air bone gap was found to be 7 dB (36.16%) and the mean improvement in the air conduction threshold was found to be 10 dB (25.23%). It was noted that there is a significant hearing improvement. CONCLUSIONS A diseased ear which is diagnosed early and operated early produces better results than a long-standing diseased ear. Also, a long-standing disease produces more hearing loss because of reasons like bone erosion and mucosal change.
