[A case of paroxysmal tinnitus and nystagmus accompanied by facial spasm].
Trigeminal neuralgia and facial spasm are usually caused by cross vascular compression of the trigeminal root entry zone and facial nerve exit zone. A similar mechanism is believed to affect the acoustic nerve as well, giving rise to tinnitus and nystagmus. We present one case of paroxysmal tinnitus and nystagmus, accompanied by facial spasm, and discuss the mechanism and the significance of the neurotological examination.
