A case of neurovascular compression of the /th and 8th cranial nerves was reported. The patient, a 53-year-old male, had a history of pulsating right tinnitus and paroxysmal dizziness with nausea and right facial spasms. For a long time, he was treated with SGB or injection of sodium bicarbonate, having been diagnosed as "Meniere's disease". In spite of these treatments, the attack of dizziness became more frequent, developing to the clustering state. Neurovascular compression of the 7th and 8th cranial nerves was confirmed when the enlarged and curved vertebral artery was found during air CT and VAG examina. tions. Therefore, Jannetta's operation (microvascular decompression) was performed by the neurosurgeons. During the operation a branch of PICA was found to be compressing both the 7th and 8th cranial nerves. After surgical treatment, pulsating tinnitus, dizziness and facial spasms disappeared, and hearing loss improved.
