Transient unilateral hearing loss induced by electrocortical stimulation

A 32-year-old patient with seizures experienced decreased right-ear hearing during electrocortical stimulation mapping of the left lateral superior temporal gyrus. Audiometric testing under headphones confirmed a reversible, moderate unilateral hearing loss. Under binaural listening conditions, audi...

Beschreibung
Zusammenfassung:	A 32-year-old patient with seizures experienced decreased right-ear hearing during electrocortical stimulation mapping of the left lateral superior temporal gyrus. Audiometric testing under headphones confirmed a reversible, moderate unilateral hearing loss. Under binaural listening conditions, auditory comprehension was impaired at the same site, whereas word repetition, environmental sound recognition, naming, and spontaneous speech remained intact.
