The sympathetic nerve block improves the blood flow in the innervated regions. For this region, the sympathetic nerve block has been performed in the neural and cerebral disorders. However, the cerebral blood flow regulation of the cranial cervical ganglion block in dogs have not been well defined and the correlation to the changes in the cerebral circulation and the changes in the electroencephalogram is not well defined in dogs yet. Therefore, we investigated the hypothesis that changes in the EEG could be affected by the changes in cerebral blood flow following the cranial cervical ganglion block in dogs. Twenty five beagle dogs were divided into 3 groups; group I(LCCGB, n=10) underwent left sided cranial cervical ganglion block using the 1% lidocaine, group II(L, n=10) injected the 1% lidocaine into the right or left sided digastricus muscle, group III(N/SCCGB, n=5, served as control) underwent the left sided cranial cervical ganglion block using saline. A statistical difference was not found between the control group and the LCCGB group in the 95% spectral edge frequency(SEF) and the median frequency(MF). In the relative band power, the $\delta$ frequency was decreased during 5-25 min, while the $\alpha$ frequency was increased during the same time(p<0.05). But the $\theta$ frequency and the $\beta$ frequency were not shown the significant changes compared with the control group during the same time(p<0.05). These results suggest that the left cranial cervical ganglion block does not induce the change of the cerebral blood flow and its effect is insignificant.

Dolichoectasia of the intracranial arteries is a rare condition characterized by elongated and tortuous arteries due to progressive destruction of the vessel walls. Although most patients present with cerebrovascular accidents, our patient presented with intractable facial pain along the distribution of the trigeminal nerve. Clinical examination revealed involvement of the 5th, 7th, and 8th cranial nerves, and subsequent MRI showed dolichoectasia of the left basilar artery. The patient experienced symptomatic relief after a trial of carbamazepine along with botulinum toxin injections.

The authors have effectively treated a case of true trigeminal neuralgia involving the 3rd branch of the 5th cranial nerve by mandibular nerve block with alcohol and Dilantin administration, and reached following results. 1. Alcohol injection has a definite value as the primary treatment of trigeminal neuralgia. 2. It is not yet to be clarified whether the effects of alcohol injection and Dilantin therapy reveal synergism. 3. Phenobarital was given as an adjuvant of Dilantin, but its effect on the painful paroxysms is questionable.

Moebius syndrome is a rare, congenital neurological disease involving facial paralysis and limitation of eye movements. It results from maldevelopment of the sixth and seventh cranial nerves. Dental features of this syndrome include micrognathia, microstomia, tongue deformity, cleft palate, hypoplasia of the teeth, and congenital missing teeth. A 7-year-old female with Moebius syndrome was referred from a local dental clinic for caries treatment. She presented with facial paralysis and microstomia. Oral findings included multiple caries with enamel hypoplasia, congenital missing teeth, and tongue deformity. Dental treatments including restorative and preventive procedures were performed. Oral findings and management aspects of Moebius syndrome for this case are discussed. Early evaluation and multidisciplinary care are needed for children with Moebius syndrome.

A group of 49 patients with neurogenic tumor in head and neck except intracranial tumor & Von-recklinghausen's disease was treated at the Department of Surgery. Presbyterian Medical Center during 12 years from January, 1980 to December, 1991. Of the 49 cases, 24 cases were neurilemmoma, 23 cases neurofibroma and 2 cases malignant schwannoma. The lateral cervical region was the commonest location of the neurogenic tumors, 24 cases (49%) arose from posterior triangle of neck and 12 cases from anterior triangle of neck. The origin of nerve was identified in 28 cases(57%). Cervical plexus(10 cases) and brachial plexus(7 cases) were most commonly affected. The most common site of neurogenic tumors arose from cranial nerve was anterior cervical triangle.

Intraoperative neuromonitoring (INM) is well known to be useful method to reduce intraoperative complications during the surgery of nervous system lesions. Evoked potentials are most commonly used among the electrophysiological tests. Brainstem auditory evoked potentials are for detecting the problems along the auditory pathways including the eighth cranial nerve and brainstem. Somatosensory evoked potentials are applied for preventing the spinal cord lesions. The INM is affected by many factors. In order to perform an optimal INM, the confounding factors including technical, anesthetical, and individual factors should be kept well under control. INM has frequent electrophysiologic changes during the surgery and it might be helpful to keep one's eyes on which monitoring modalities are reluctant to change during each operation. The skillful monitoring and timely interpretation of electrophysiologic changes can drive the patient to be undergone surgery, even in high surgical risk group.

Idiopathic facial nerve palsy, or Bell's palsy(BP) is an acute paralysis of the facial muscles innervated by the seventh cranial nerve. The cause and prognosis of recurrent BP are various. The frequency and heterogenicity of etiology suggest a predisposing factor or immune mechanisms. About 10% to 15% of patients with BP will suffer a recurrence, and less than 1.5% will have more than 4 episodes. We report four patients of chronic recurrent BPs.

Stabismus refers to a muscle imbalance that results in improper alignment of the visual axes of the two eyes. It may be divided into paralytic and nonparalytic strabismus. Paralytic strabismus is primarily a neurologic problem ; nonaralytic strabismus is more strictly an ophthalmologic problem. Characteristic clinical disturbances result from lesions of the third, fourth, and sixth cranial nerves. Lesions of the sixth nerve result in a paralysis of lateral or outward movement and a crossing of the visual axes. We present a case of paralytic strabismus in 24-year-old female who recovered by Oriental medicine, including acupuncture and herbal medicines.

Neurilemmomas are well-encapsulated, benign, slow-growing tumors originating from Schwann cells of the nerve sheath surrounding cranial, peripheral, or autonomic nerves. Intraoral neurilemmomas are relatively rare and have a wide variety of morphologic and radiologic features. This makes differential diagnosis difficult, and only histopathological features can lead to a definitive neurilemmoma diagnosis. In this report, we present the case of a 30-year-old woman whose chief complaint was a solitary, nodular mass on the right floor of the mouth. After computed tomography and magnetic resonance imaging, we performed an incisional biopsy that showed the typical characteristics of a neurilemmoma. The mass was removed completely through an intraoral surgical approach. Despite losing a portion of the lingual nerve, the patient did not complain of any specific discomfort. Wound healing was uneventful and there were no signs or symptoms of recurrence.

As benign tumor originating in Schwann cells of nerve sheath, Schwannoma can rise in any site involving cranial nerve, sympathetic nerves, peripheral nerves excepting optic nerves and olfactory nerves. Schwannoma rarely occurs in trachea, and although can appear in any part, most often seen in the lower third of the trachea. Here, we reported a case of intra-tracheal schwannoma misdiagnosed and treated as bronchial asthma, later identified and successfully excised through an external approach.
