INTRACRANIAL NEURECTOMY OF THE SUPERIOR AND INFERIOR MAXILLARY NERVES FOR TIC DOULOUREUX

The differential diagnosis and treatment of tic douloureux.

Electromagnetic Induction Aberration: The Possible Mechanism of Tic Douloureux

A theory based on the principles of electromagnetic induction aberration is presented as the possible mechanism of classic trigeminal neuralgia, tic douloureux. The anatomy of the dorsal root entry zone of the trigeminal nerve at the pons in the proximity of the superior cerebellar artery presents a scenario conducive to the phenomenon of electromagnetic induction. When the action potentials tr...

Dolichoectasia of vertebrobasilar system: a rare cause of tic douloureux.

The usual outcome of rudimentary horn pregnancy is rupture in second trimester in 90% of cases.[1] Early diagnosis of this rare form of pregnancy prior to rupture is essential for successful management in order to prevent maternal morbidity and mortality.[2] Though uterine anomalies can be suspected on bimanual or ultrasonographic examination,[2,3] these can be diagnosed in only 14% cases befor...

Effects of intracranial trochlear neurectomy on the structure of the primate superior oblique muscle.

PURPOSE. Although cyclovertical strabismus in humans is frequently attributed to superior oblique (SO) palsy, anatomic effects of SO denervation have not been studied. Magnetic resonance imaging (MRI) and orbital histology was used to study the effects of acute trochlear (CN4) denervation on the monkey SO. METHODS. Five juvenile macaque monkeys were perfused with formalin for 5 weeks: 15 months...

Neurovascular decompression with selective partial rhizotomy of the trigeminal nerve for tic douloureux.

Fourteen patients with classic tic douloureux were treated with neurovascular decorapression of the trigeminal nerve at its zone of entry into the pons. In addition, selective rhizotomy of the portio major was performed in each patient. This combined procedure gave excellent relief of pain with no recurrences in a 23-month postoperative period. Technical observations and postoperative complicat...
