Abstract
Abstract Chronic suppurative otitis media (CSOM) is defined as chronic otorrhea (i.e., lasting > 6-12 weeks) through a perforated tympanic membrane. It is generally associated with some degree of conductive hearing loss. However, recurrent ear infections due to perforated eardrum result in absorption of toxins and macromolecules into the cochlea leading to sensorineural hearing loss (SNHL). We planned to determine the frequency of sensorineural hearing loss in chronic suppurative otitis media. A descriptive cross-sectional study was conducted at Aga Kgan University Hospital, Karachi, from October 2013 to March 2014. Average threshold of speech frequencies was calculated via pure tone audiogram for both diseased and normal contralateral ear. A mean of >25db in diseased ear was labelled as positive case for SNHL. SNHL was reported in 64(52%) patients and the frequency was found to increase with increasing duration. Patients with CSOM should be counselled regarding the risk of developing SNHL if left untreated.
