hemifacial spasm/dental caries

The etiology of hemifacial spasm had long been obscure until 1962 when Gardner proved that this hyperdysfunction of the facial nerve was caused by mechanical compression of the facial nerve by vascular structures in the posterior cranial fossa. In 1977, Jannetta proposed a specific location at the

30 years ago Janetta proposed neurovascular compression as an etiology factor of trigeminal neuralgia. Neuroanatomical, neurophysiological studies and observations during neurosurgical operations seems to confirm Janetta's suggestions. The conception of neurovascular compression was accepted also as

Pulsatile tinnitus of nonvascular origin is rare. We herein present a case of pulsatile tinnitus complicated with Jannetta surgery due to a communication created between the drilled mastoid cells and epidural space. She was successfully cured by otological surgery where the mastoid tip was packed

A case of tentorial cavernous angioma is reported. A 61-year-old woman was admitted because of left auditory disturbance and left hemifacial spasm. CT scan and angiography, MRI revealed a dumb-bell typed tumor extended above and below the left tentorium cerebelli. Under the preoperative diagnosis of

We developed and tested a new, angled rigid endoscope as a tool for performing continuous visual monitoring during microsurgery. The shaft of the scope is angled 110 degrees at its midportion using a prism. We used the scope continuously in 30 cases including 15 pituitary tumours, 7 brain tumours, 7

Our objective is to present surgical techniques used for the prevention of cerebrospinal fluid leakage after microvascular decompression (MVD). From January 1996 to February 2006, microvascular decompression for hemifacial spasm or trigeminal neuralgia was performed in 678 consecutive patients. In

Intraoperative recordings obtained from electrodes placed on the scalp (vertex and earlobe or ear canal) in response to click stimulation were compared with recordings made directly from the auditory nerve in patients undergoing microvascular decompression (MVD) operations to relieve hemifacial

Cholesterol granulomas of the head are relatively rare. Isolated lesions of the cerebellopontine angle are even more uncommon. In this report, 17 cases of petrous apex cholesterol granulomas are presented and management is discussed. Symptoms at presentation included dizziness (14 patients),
