Case ReportsOcular neuromyotonia treated by microvascular decompression: usefulness of preoperative 3D imaging: case report.
Ocular neuromyotonia is a rare ocular motility disorder characterized by involuntary contraction of extraocular muscles resulting in paroxysmal diplopia. Although ocular neuromyotonia is reported as a rare complication after radiation therapy, there are a few cases of ocular neuromyotonia in the absence of irradiation. ⋯ The authors report a case of ocular neuromyotonia treated by microvascular decompression of the third cranial nerve, supporting the hypothesis that neurovascular compression may play a role in its pathogenesis. The usefulness of preoperative 3D imaging for microvascular decompression is also discussed.

Interactive virtual simulation using a 3D computer graphics model for microvascular decompression surgery.
The purpose of this paper is to report on the authors' advanced presurgical interactive virtual simulation technique using a 3D computer graphics model for microvascular decompression (MVD) surgery. ⋯ Our interactive virtual simulation using a 3D computer graphics model provided a realistic environment for performing virtual simulations prior to MVD surgery and enabled us to ascertain complex microsurgical anatomy.

A clinical analysis on microvascular decompression surgery in a series of 3000 cases.
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. ⋯ A prompt recognition of the conflict site leads to a successful MVD. To facilitate the approach, the craniotomy should be lateral enough to the sigmoid sinus. The whole intracranial nerve root should be examined and veins or arterioles should not be ignored. For TN, all the vessels contacting the nerve should be detached. For HFS, the exposure should be medial enough to the pontomedullary sulcus.

Microvascular decompression for hemifacial spasm: technical notes on pontomedullary sulcus decompression.
Hemifacial spasm usually results from compression of facial nerve by offending vessels. During microvascular decompression, offending vessels at pontomedullary sulcus are obscured by the lower cranial nerve roots, making exposure and surgery difficult. This study discusses the techniques for decompression of offending vessels in this area. ⋯ Microvascular decompression for hemifacial spasm can be performed with satisfying results if there is full exposure and protection of the perforating vessels, appropriate use of the spaces between cranial nerve roots, and attention paid to the characteristics of offending vessels.

Case ReportsHemimasticatory spasm treated with microvascular decompression of the trigeminal nerve.
Hemimasticatory spasm is a very rare disorder of the trigeminal nerve characterized by paroxysmal involuntary contraction of the jaw-closing muscles. The mechanisms leading to hemimasticatory spasm are still unclear. Recently, injection of botulinum toxin has become the treatment of choice due to its excellent results. We report a case of a successful treatment of hemimasticatory spasm via microvascular decompression of the motor branch of the trigeminal nerve.
