ABSTRACT
Auditory neuropathy spectrum disorder (ANSD) is a recently discovered hearing disorder. Across literature there are dearths of studies which documents for unilateral auditory neuropathy spectrum disorder (UANSD). The current study describes a 20 year old male presenting with a complaint of hearing difficulty since few years in adverse listening conditions. The subject had no family and medical history which can directly or indirectly have an impact on auditory system. Previous audiological evaluation reveals unilateral severe sensori-neural hearing loss. Radiological evaluation reveals no structural abnormalities. The objective of the current study is to reach the correct diagnose for the case observed with unique feature using test battery approach. Method of the current study involves an intensive diagnostic approach starting from case history, Otoscopic evaluation; Behavioral measures, physiological measures and electrophysiological measures. However the result of the current study is strongly indicating towards the classic condition of ANSD.
