Neurilemmoma is a relatively rare benign tumor which may be derived from nerve sheath of the peripheral, sympathetic and cranial nerve except the optic nerve and olfactory nerve. And it is a characteristically solitary and well-encapsulated mass. About 25% of neurilemmoma occurs in the head and neck region and the acoustic nerve is most frequently involved, but neurilemmoma of the larynx is rare. Recently, we experienced a case of neurilemmoma occurred in the right aryepiglottic fold of the larynx. The tumor was successfully removed by transoral approach under direct laryngoscope. So we report this case with literature review.

We have studied the effect and application of CST which is the function and disease of the autonomic nerve system based on recovery of flexibleness of the autonomic nerve. CST purpose to keep sustenance of human body by recovering joints have limitation of mobility and controlling autonomic nerve system by diminution tense of the sympathetic nerve. CST makes well flowing of CSF by pressure the fourth ventricle of the brain or relaxation of soft tissues of the base of a cranial bone. There is no result of studies about CST in Korea yet. It will bring a benefit if it prove the effect of CST in countries depend on drugs way high such as Korea. It needs positive approach and definite research for the improvement.

Objective : Several conservative treatments have been tried in peripheral facial nerve paralysis, because 80% of patients recover spontaneously. Surgical decompression may be helpful to the residual, medically intractable patients. We present here our experiences of facial nerve decompression via middle fossa approach, which seems to be one of good surgical therapeutic options for medically refractory peripheral facial nerve paralysis. Method : Three cases of medically intractable peripheral type facial paralysis were microscopically operated via middle cranial fossa approach to decompress the labyrinthine segment of the facial nerve and geniculate ganglion by searching landmarks of middle meningeal artery, greater superficial petrosal nerve and facial hiatus. Results : After operation, two cases of Bell's palsy improved substantially and one case of post-traumatic facial paralysis improved partially. Conclusion : This report is presented to describe the surgical facial nerve decompression via middle fossa for early control of peripheral type facial paralysis. Surgical decompression of edematous peripherally paralysed facial nerve could be preferred to conservative treatment in some patients although more surgical experience should be required.

Objective : Pituitary apoplexy (PA) is described as a clinical syndrome characterized by sudden headache, vomiting, visual impairment, and meningismus caused by rapid enlargement of a pituitary adenoma, We retrospectively analyzed the clinical presentation and surgical outcome in PA presenting with cranial neuropathy. Methods : Twelve cases (33%) of PA were retrospectively reviewed among 359 patients diagnosed with pituitary adenoma, The study included 6 males and 6 females, Mean age of patients was 49,0 years, with a range of 16 to 74 years, Follow-up duration ranged from 3 to 20 months, with an average of 12 months, All patients were submitted to surgery, using the transsphenoidal approach (TSA). Results : Symptoms included abrupt headache (11/12), decreased visual acuity (12/12), visual field defect (11/12), and cranial nerve palsy of the third (5/12) and sixth (2/12) Mean height of the mass was 29.0 mm (range 15-46) Duration between the ictus and operation ranged from 1 to 15 days (mean 7.0) The symptom duration before operation and the recovery period of cranial neuropathy correlated significantly (p = 0.0286) TSA resulted in improvement of decreased visual acuity in 91.6%, visual field defect in 54.5%, and cranial neuropathy in 100% at 3 months after surgery. Conclusion : PA is a rare event, complicating 3.3% in our series, Even in blindness following pituitary apoplexy cases, improvement of cranial neuropathy is possible if adequate management is initiated in time, Surgical decompression must be considered as soon as possible in cases with severe visual impairment or cranial neuropathy.

Oculomotor nerve palsy presents itself with sudden onset unilateral ptosis and inability to turn the eye upward, downward, or inward, which causes visual disturbances. Strabismus caused oculomotor nerve palsy refers to muscle imbalance that results in improper alignment of the visual axes of the two eyes It may be divided into paralytic and non paralytic strabismus. paralytic strabismus is primarily a neurologic problem. Characteristic clinical disturbances result from lesions of the third, fourth, and sixth cranial nerves. Lesions of the third nerve result in a paralysis of lateral or outward movement and a crossing of the visual axes. Objective: This study was designed to evaluate the effects of oriental medicine therapy on a peripheral oculomotor nerve palsy. Methods & Result: The clinical data was analyzed on a patient with oculomotor nerve palsy whose main symptoms were right side ptosis and inability to turn the eye inward. The patient was treated by the electroacupucture(4Hz frequency, intensity was adjusted so that localized muscle contractions could be seen). As the result, symptoms are improved remarkably. Conclusion: The patient showed right eye ptosis and unilateral deviation of the right eye ball in neutral position. After acupuncture treatment and electroacupuncture treatment, the ptosis and deviation of the patient's right eye was recovered six weeks after the onset. The study suggests that oriental medicine therapy is significantly effective on the treatment of peripheral oculomotor nerve palsy.

Background: The compression of 7th cranial nerve by arteries is one of the various causes of hemifacial spasm (HFS). A few previous studies were revealed the relation between the compression of 7th cranial nerve and common trunk anomaly. We evaluated the common trunk anomalies in patients with HFS using MRI and MRA. Methods: From January 2001 to December 2005, 41 consecutive patients (9 men, mean age $54.5{\pm}12.6$) with HFS underwent MRI and MRA. T2 axial images and time-of-flight angiographies were reviewed for identification of the compression at root exit zone by two neuroradiologists and one neurologist. Results: Thirty-seven patients showed neurovascular compression on the lesion side. Twenty patients of them were shown the compression of 7th cranial nerve by anterior inferior cerebellar artery (AICA), and seventeen patients of them were shown the compression by posterior inferior cerebellar artery (PICA). Twenty-four patients of the thirty-seven patients had common trunk anomaly. In control, twelve of twenty-one subjects had common trunk anomaly, that the frequencies of common trunk anomaly of two groups were 58.8% in HFS and 57.1% in controls. In the twenty-four patients with common trunk anomaly, eighteen patients had dominant-AICA, and six patients had dominant-PICA. The rate of nerve compression by common trunk anomaly in the HFS with unilateral common trunk, dominant-AICA was 76.5% and dominant-PICA was 100%. Conclusions: This study also revealed that AICA was most common compressive artery. There was no difference between the HFS groups and control groups in frequency of common trunk anomaly. Thus, we could not demonstrate the relationship between common trunk anomaly and HFS.

Neurilemmomas are uncommon benign tumors originating from the schwann cells of various cranial nerves, spinal nerves, and autonomic nerves. About 25% of the disease is found in the head and neck region and the most common single site of origin is known to be the acoustic nerve. However neurilemmomas of the peripheral segment of the lingual nerve are extremely rare neoplasms. We recendy experienced a case of a benign neurilemmoma of the lingual nerve and this case may be the second to be reported in the literature.

Isolated hypoglossal nerve palsy is a rare clinical condition and it causes deviation of the tongue and dysarthria. A 50-year-old female presented with tongue deviation to the left and mild dysarthria. She had no remarkable past medical history except several recent upper respiratory infections. On examination, the other cranial nerves were intact and she had no focal neurological signs. The findings of MRI and MR angiography were normal. Cerebrospinal fluid analysis revealed only mild elevation of protein. We diagnosed her as suffering with idiopathic isolated hypoglossal nerver palsy and we administered steroid therapy. The dysarthria was improved, but the tongue deviation still remained at 50 days after onset. We report here on a rare case of idiopathic isolated hypoglossal nerve palsy.

Upon review, it is noted that recurrent painful ophthalmoplegic neuropathy (RPON) is a rare neurological syndrome characterized by recurrent unilateral headaches and painful ophthalmoplegia of the ipsilateral oculomotor nerve. As seen on brain MRI, thickening and enhancement of the oculomotor cranial nerve can be observed in these cases. We experienced a case of RPON in an adult patient who showed thickening and enhancement of the oculomotor nerve on gadolinium-enhanced 3D-FLAIR image. The authors report a case of RPON with a review of the literature.

Objective : Cerebral aneurysms which cause oculomotor nerve [cranial nerve (CN) III] palsy, are frequently found with a daughter sac of the aneurysm dome. We assumed that CN III might be compressed by the daughter sac and it would be more helpful not to fill the daughter sac with coils than vice versa during endosaccular embolization for recovering from CN III palsy, because it may give a greater chance for the daughter sac to shrink by itself later. We reviewed the initial results of our experiences of such cases. Methods : Among 9 aneurysms accompanied by CN III palsy, 7 (6 unruptured, 1 ruptured) showed a daughter sac. We tried to fill the main dome completely and spare the daughter sac from coil filling to increase the possibility of decompression. We evaluated the short-term effectiveness of this concept using medical records and angiograms. Results : After initial embolization, all of CN III palsy caused by unruptured aneurysms (6/6) resolved completely after various periods (3-90 days) of time. No adverse effects were noted during and after the procedures except for one case of harmless coil stretching during coil filling using double microcatheter. Conclusion : During the coil embolization of the cerebral aneurysm causing CN III palsy, sparing the daughter sac from coil packing while tightly packing the main dome, can be helpful in increasing the effectiveness of decompression. However, a long-term follow-up will be required.
