Vestibular Impairment in Hemifacial Spasm Syndrome: A Case Report
Barona L (1), Krstulovic C (1), Bejarano B (2), Perez N (3).
A 52-year-old man presented with left hemifacial spasm (HFS). A magnetic resonance imaging scan showed compression of the left facial nerve at the cerebellopontine angle by a dolichoectatic basilar artery. The neurotological evaluation showed an otolithic deficit, with canalicular preservation and normal hearing.
The deficit improved after surgical decompression. No previous report has described the impairment of vestibular function in patients presenting with HFS.
