A Study of Correlation Between Sensorineural Hearing Loss and Duration of Chronic Otitis Media

Dr. Somashekara K. G. , Dr. Apurva Anil Jarandikar

Abstract :

The diagnosis of chronic otitis media (COM) implies 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. It results in some degree of conductive heå loss because of perforated tympanic memane with or without ossicular destruction. However, recurrent ear infections due to perforated tympanic memane may result in absorption of toxins and macromolecules in the cochlea leading to sensorineural heå loss (SNHL). This study was done to evaluate the correlation between the SNHL and duration of COM. Average threshold of speech frequencies was calculated using pure tone audiogram. The sensorineural heå loss was found to be increased with increasing duration of the disease. Counselling of patients with regards to the risk of SNHL is needed.
