Abstract
Chronic suppurative otitis media (CSOM) is defined as chronic ear discharge (i.e. lasting > 6-12 weeks) through a tympanic membrane perforation. It is generally associated with some degree of conductive hearing loss because of perforated tympanic membrane or ossicular destruction. However, recurrent ear infections due to perforated eardrum may result in absorption of toxins and macromolecules in the cochlea leading to sensorineural hearing loss (SNHL). This study was done to evaluate the frequency of SNHL in CSOM. Average threshold of speech frequencies was calculated via pure tone audiogram. The frequency was found to increase with increasing duration of the disease. Patients with CSOM should be counselled regarding the risk of developing SNHL if left untreated.
