A total of 346 children aged between 4 and 15 years attended presenting with complaints of impaired hearing. Among them 73 children with unilateral sensorineural deafness were included in the study. After a thorough ENT examination subjective tests like pure tone audiometry and behavioral observation audiometry and objective tests like impedance audiometry, Oto-acoustic emissions (OAE), and brainstem evoked response audiometry (BERA) were performed. RESULTS While identifying the possible etiological cause of USNHL, OAE revealed 56.16% REFER and 43.83% PASS results. Impedance audiometric results showed 71.22% as Type A Tympanogram. Pure tone audiometric results were mostly showed severe and profound hearing losses together accounting to 87.66%. BERA findings were mostly on severe and profound hearing loss (90.40%).
