Aim:The aim of the present study was to determine the causes and pattern of hearing loss in a tertiary hospital.Methods:This was a retrospective descriptive study of patients who were managed for hearing loss at Department of ENT, BRLSABVMMC Rajnandgaon (C.G.) over a 1‑year period from May 2018 to May 2019.2000 patients were included in the study.Results:There were 1200 (60%) males and 800 (40%) females. The mean age was 45.5 years with SD of ± 2.20. Majority of the patients 1140 (57%) reviewed were above 20 years of age. The most common cause of hearing loss was presbycusis (age related) 400 (20%) followed by ototoxicity 200 (10 %), congenital 200 (10%), meningitis 200 (10%), chronic suppurative otitis media (CSOM) 200 (10%), and noise‑induced hearing loss 160 (8%). Most of the patients 1300 (65%) had bilateral hearing loss while 700 (35%) had unilateral hearing loss. Sensorineural hearing loss was the most common 1560 (78%), followed by conductive 340 (17%) and mixed 100 (5%) hearing losses, respectively. Majority of the patients 1300 (65%) had mild to moderately severe with the remaining 700 (35%) having severe to profound hearing losses respectively. There was no statistically significant relationship between the ages of the patients and occurrence of Type B tympanogram (P > 0.05). Conclusion:This study concluded that sensorineural hearing loss was the commonest type among the patients with a complaint of the hearing loss.Age‑related hearing loss was the most common cause of hearing loss followed by ototoxicity in this study.Majority of the patients were adult male with bilateral mild to moderately severe sensorineural hearing loss.
