Abstract
Primary jugular foramen JF tumor such as glomus jugular tumor or JF schwannoma may manifest as a lower cranial nerve deficit in addition it can be accompanied by deafness or vertigo if it affects the cranial nerve CN VIII Recently we encountered JF schwannoma 1 and glomus jugulare tumor 1 Both cases invaded the adjacent cerebellopontine angle leading to cochleovestibular deficits prior to the operation After surgery recovery of the audiovestibular function including hearing auditory brainstem response and caloric response was anticipated in both patients Therefore cochleovestibular deficits in JF tumors can be attributed to compression neuropathy rather than tumor infiltration
