OBJECTIVES Despite the vascular compression of the seventh cranial nerve has been verified by the microvascular decompression surgery as the cause of hemifacial spasm (HFS), the mechanism of the disease is still unknown. We believe that the autonomic nervous system in adventitia of the offending artery may contribute to the HFS. To prove our hypothesis, we(More)
Due to its anatomical features, the vertebrobasilar artery complex (VBA) seldom contributes to the neurovascular conflict in patient with trigeminal neuralgia (TN). However, once it offends the trigeminal root, this large artery is really difficult to manipulate during microvascular decompression (MVD) surgery. Therefore, the surgical strategy for such(More)
Hemimasticatory spasm is a rare disorder characterized by paroxysmal involuntary contraction of the jaw-closing muscles. As the ideology and pathogenesis of the disease are still unclear, there has been no treatment that could give rise to a good outcome so far. Herein, we tried to use surgical management to cure the disease. Six patients with the disease(More)
OBJECTIVE Despite the microvascular decompression (MVD) has become a definitive treatment for trigeminal neuralgia (TN) and hemifacial spasm (HFS), not all of the patients have been cured completely so far and this sort of operation is still with risk because of the critical operative area. In order to refine this surgery, we investigated thousands MVDs. (More)
OBJECTIVE Although microvascular decompression (MVD) has been accepted as effective therapy for hemifacial spasm, failed surgery has been reported frequently. For a sophisticated neurosurgeon, an apparent offending artery is seldom missed. However, it is still an embarrassed situation when the neurovascular conflict site could not be approached. METHODS(More)
Although the infratentorial superior-lateral cerebellar approach has been traditionally chosen for exposure of the V cranial nerve root in the process of microvascular decompression for treatment of trigeminal neuralgia, those petrosal veins often block this surgical corridor. To detour these petrosal veins, we require a new approach. We provide a(More)
Although neurovascular confliction was believed to be the cause of hemifacial spasm (HFS), the mechanism of the disorder remains unclear to date. Current theories, merely focusing on the facial nerve, have failed to explain the clinical phenomenon of immediate relief following a successful microvascular decompression surgery (MVD). With the experience of(More)
Hemimasticatory spasm is a rare disease; with little knowledge of the pathogenesis, it has still been intractable today. We presented a 56-year-old woman with involuntary painful spasm in her left masseter muscle for 11 years. The patient was successfully treated with microvascular decompression surgery. An offending superior cerebellar artery was found to(More)
Painful tic convulsif is referred to as the concurrent trigeminal neuralgia and hemifacial spasm. However, painful tic convulsif after ipsilateral Bell palsy has never been reported before. We report a case of a 77-year-old woman with coexistent trigeminal neuralgia and hemifacial spasm who had experienced Bell palsy half a year ago. The patient underwent(More)
