reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. almost all cases of trigeminal neuralgia (tng) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (hfs) (nine out of 10 c...

PURPOSE To assess the most effective magnetic resonance imaging (MRI) sequence for the visualization of the 9th, 10th, and 11th cranial nerves (glossopharyngeal, vagus, and accessory nerves, respectively) in their intraforaminal/canalicular courses. MATERIALS AND METHODS Balanced fast-field echo (b-FFE), 3D-T2W DRIVE, T2W 2D TSE and post-contrast T1W MRI sequences were all applied and we trie...

PURPOSE To study the innervation of the aqueous outflow channels and scleral spur by autonomic nerves containing substance P. METHODS The experiments were conducted on guinea pigs. Immunohistochemical techniques and capsaicin-ablation of the sensory nerves were used to investigate nerves containing substance P at the light and electron microscopic level. RESULTS Nerves containing substance ...

Tooth pulpal nerves include sympathetic and sensory nerves that originate from trigeminal ganglion .From the terminal of these sensory nerves neuropeptides are secreted that are neuromodulators and neurotransmitters. One of them is CGRP (Calcitonin gene-related protein) which has a vasodilatory effect on pulpal vessels. Near abscess and moderate injuries, this neuropeptide can lead to neural fi...
