Altered Contralateral Auditory Cortical Morphology in Unilateral Sudden Sensorineural Hearing Loss

Abstract

This study confirms that detectable decreased contralateral auditory cortical morphological changes have occurred in unilateral SSNHL patients within the acute period by voxel-based morphometry methods. The gray matter volumes of these brain areas also perform a negative correlation with the duration of the disease, which suggests a gradual brain structural impairment after the progression of the disease.
