متن کاملAmplification Options in Children with Auditory Neuropathy Spectrum Disorder
Auditory neuropathy spectrum disorder (ANSD) is a specific form of hearing loss characterized by the presence of normal or near-normal Otoacoustic Emissions (OAEs) but the absence of normal middle ear muscle reflex and severely abnormal or completely absent auditory brainstem response (ABRs). Amplification is considered a dilemma in such disorder with a lot of debates. This article will review ...
