Speech Perception Impairment Follow Complete Recovery of Sudden Sensorineural Hearing Loss

At present, few research on the auditory perception function and possible neural mechanisms of unilateral sudden hearing loss patients with complete or partial recovery of peripheral hearing.This project evaluate the speech perception function in noise of unilateral sudden hearing loss patients with with complete and partial hearing recovery by cognitive behavioral experiments, event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI), and longitudinal follow-up to explore its underlying neural mechanisms.

Inclusion Criteria:18-65 years old;patients with unilateral idiopathic sudden sensorineural hearing loss (at least three adjacent frequencies of hearing loss ≥ 30 dB );the first onset;Contralateral hearing is normal; 5) Hearing is cured after treatmentExclusion Criteria:Sudden deafness with possible definite etiology, such as Meniere's disease, large vestibular aqueduct syndrome, trauma, retrocochlear tumor, etc.;Severe underlying diseases, heart disease, blood disease, pregnancy, breastfeeding, etc.;Suffering from other central diseases that may affect speech perception disorders, such as Alzheimer's disease, etc.;Those who cannot cooperate with the whole study inspection;Those who do not agree to be enrolled or refuse to sign the informed consent form;Those who are using may affect the Medications or treatments for speech perception disorders.
