The herpes zoster infecting ophthalmic branch of trigeminal Nerve that is similar to migraine at first stage symptom has been treated with oriental medication at Dept. of Internal Medicine, Semyung University Oriental Hospital. The fIrst symptom of roster is burning pain, tingling or extreme sensitivity in one area of the skin, usually limited to one side of the body. This may be present for one to three days before a red rash appears at that site. There may also be a fever or headache. The rash soon turns into groups of blisters. The blisters start out clear but then pus or dark blood collects in the blisters before they crust over (scab) and begin to disappear. The pain may last longer. In this case, the severe pain was present for five days, the blisters and scabsdisappeared entirely on the seventeenth day, but postherpetic neuralgia, the most common complication and is observed most frequently in the ophthalmic branch of trigeminal nerve, was not prevented entirely. We have observed this case and report to help treatment on this disease at oriental medicine clinic.

The present study was undertaken to investigate the morphological characteristics of trigeminal nerve in the Korean native goat by macroscopic methods. Trigeminal nerve was originated from the lateral side of pons, and extended shortly forward to form trigeminal ganglion at the opening of oval foramen. Thereafter this nerve was divided into maxillary, mandibular and ophthalmic nerve. Ophthalmic nerve gave off the zygomaticotemporal branch, frontal nerve, frontal sinus branch, and was continued as the nasociliary nerve. Maxillary nerve gave rise to the zygomaticofacial branch, accessory zygomaticofacial branch, communicating branch with oculomotor nerve, pterygopalatine nerve, caudal superior alveolar branch, malar branch and was continued as the infraorbital nerve. Mandibular nerve was divided into the masseteric nerve, buccal nerve, lateral pterygoid nerve, medial pterygoid nerve, nerve to tensor tympani m., auriculotemporal nerve, and furnished the inferior alveolar nerve and lingual nerve as terminal branches. The course and distribution of the trigeminal nerve in the Korean native goat appeared to be similar to that in other small ruminants such as sheep and goat. But the main differences from other small ruminants were as follows : 1. There was no accessory branch of the major palatine nerve. 2. The caudal superior alveolar branch was directly branched from the maxillary nerve. 3. The communicating branch with oculomotor nerve was originated from maxillary nerve or common trunk with zygomaticofacial branch. 4. The malar branch arose from the maxillary nerve at the rostral to the origin of the caudal superior alveolar branch. 5. The inferior alveolar nerve originated in a common trunk with the lingual nerve. 6. The mylohyoid nerve arose at the origin of the inferior alveolar nerve. 7. The zygomaticotemporal branch was single fascicle, and gave off lacrimal nerve and cornual branch. 8. The base of horn was provided by the cornual branches of zygomaticotemporal branch and infratrochlear nerve of nasociliary nerve.

A 35-year-old man's vision had progressively deteriorated over a 3-month period. His left visual acuity was 5/20. Enhanced orbital computed tomographic (CT) scans revealed a fusiform dilatation of the ophthalmic artery in the left optic canal. Cerebral Angiography revealed a fusiform aneurysm on the left ophthalmic artery in the optic canal, measuring $6.2{\times}4.6\;mm$ in size. Four days after admission, visual acuity dropped to hand-motion. Endovascular treatment was chosen and a microcatheter was guided into the proximal segment of the ophthalmic artery. Using 4 detachable coils, parent artery occlusion was done. Three months after the intervention, the visual acuity in his left eye improved to 20/20. Dramatic recovery of visual acuity is exceptional with an ophthalmic artery trunk aneurysm. When an occlusion of the proximal ophthalmic artery is the only treatment option in such a situation, the endovascular occlusion of the proximal ophthalmic artery is quite feasible in the sense that it does not require any optic nerve manipulation.

The trigeminal nerve, one of the cranial nerves, innervates the maxillofacial area and has three branches: the ophthalmic, maxillary, and mandibular nerves. Paresthesia, due to damages to the inferior alveolar nerve and mental nerve (branches of the mandibular nerve), is quite frequent in dental implants and third molar extractions. As medical disputes are increasing, it is necessary to formulate an objective and reasonable disability evaluation. When evaluating the frequent rate of impairment for inferior alveolar nerve damage, it may be reasonable to follow the criteria for the rate of maxillofacial impairment of the American Association of Oral and Maxillofacial Surgeons (AAOMS) - the most scientific and reputable criteria based on the American Medical Association (AMA). Therefore, the Committee of Guides for Maxillofacial Impairment Ratings, in the Korean Association of Oral and Maxillofacial Surgeons (KAOMS), is trying to suggest more reasonable and realistic guidelines for evaluating impairments by reviewing the current evaluation criteria and those of AMA and AAOMS.

Trigeminal neuralgia is a condition characterized by excruciating paroxysms of pain in lips, gums, cheek, or chin, and very rarely, in the distribution of the ophthalmic division of the trigeminal nerve. There are many treatments of trigeminal neuralgia, such as, medical treatment, electrical stimulation, radiation therapy and ablative procedures. Infraorbital nerve block with pure ethyl alcohol is an ablation procedure for trigeminal neuralgia. We injected pure ethyl alcohol into the infraorbital foramen for pain control. The results were as follows; 1) The infraorbital nerve block with pure alcohol was an a simple and an effective method. 2) Complication, included a mild sensory deficit and mild edema over the infraorbital area.

Posterior superior alveolar nerve block (PSANB) is one of the most common and safe injection techniques in the field of dentistry. As with any other procedure, it also has inherent complications, of which ophthalmic complications are relatively rare. Transient diplopia following the administration of PSANB is rare and daunting for both the patient and the clinician. We present a case of transient diplopia in a 26-year-old female patient following administration of PSANB and review its probable pathophysiology and management and prevention.

Postoperative maxillary cyst (POMC) is relatively common complication among patients who underwent Caldwell-Luc surgery. Patients with POMC usually have no symptoms, although cyst extension can result in bone destruction or cystic infection with pain. The trigeminal nerve consists of the ophthalmic nerve, maxillary nerve, and mandibular nerve. Among these branches, the maxillary nerve runs to the lateral and frontal sides of the maxillary sinus wall. POMC can rarely lead to trigeminal neuropathy caused by cyst enlargement that compresses some branches of the trigeminal nerve. Recently, we experienced a case with trigeminal neuralgia due to POMC. The patient was successfully treated with inferior meatal antrostomy. We report this rare case with a literature review.

The fine structure of retinal tissue was studied to investigate on effect of Laser irridation on the ICR mouse with electron microscope. The results obtained were as follows: 1. At the normal groups, the most retinal layers were a complex structure, consisting of several specific cells and nerve fiver. 2. In the increasing time of Laser irridation, each cell layer of retina was not uniform of the structure and band. The visual cells were severely heterochromatin swelling of cytoplasm, irregular shape & heterochromatin of nuclear, and disappear of some cytoplasm. The nucleus and nerve fiber of retinal layer was a very irregular shape, formation of vesicle, not identify of each intercellular boundary. The pigment epithelial cells were not an uniform, a large vesicle formation of cytoplasm, and a condensation & very irregular shape of nucleus.

Trigeminocardiac reflex (TCR) is a well-known brainstem reflex that manifests as hypotension, bradycardia, dysrhythmia, and asystole when stimulation is applied to a branch of the trigeminal nerve. Most commonly associated with ophthalmic, orbital, and neurologic surgeries, mandibular division and oral cavity variants occur far less frequently. Here, we describe a case of asystolic TCR elicited by lingual nerve stimulation. This case highlights the role of specific anesthetic medications in modulating this phenomenon and reinforces the need for early recognition and clear communication in case of its occurrence. Anesthesia providers must consider discontinuing or avoiding certain medications when clinically appropriate, even during low TCR-risk procedures.

Objective : Although removal of the anterior clinoid process (ACP) is essential surgical technique, studies about quantitative measurements of the space broadening by the anterior clinoidectomy are rare. The purposes of this study are to investigate the dimension of the ACP, to quantify the improved exposure of the parasellar space after extradural anterior clinoidectomy and to measure the correlation of each structure around the paraclinoidal area. Methods : Eleven formalin-fixed Korean adult cadaveric heads were used and frontotemporal craniotomies were done bilaterally. The length of C6 segment of the internal carotid artery on its lateral and medial side and optic nerve length were checked before and after anterior clinoidectomy. The basal width and height of the ACP were measured. The relationships among the paraclinoidal structures were assessed. The origin and projection of the ophthalmic artery (OA) were investigated. Results : The mean values of intradural basal width and height of the ACP were 10.82 mm and 7.61 mm respectively. The mean length of the C6 lateral and medial side increased 49%. The mean length of optic nerve increased 97%. At the parasellar area, the lengths from the optic strut to the falciform liament, distal dural ring, origin of OA were 6.69 mm, 9.36 mm and 5.99 mm, respectively. The distance between CN III and IV was 11.06 mm. Conclusion : With the removal of ACP, exposure of the C6 segments and optic nerve can expand 49% and 97%, respectively. This technique should be among a surgeon's essential skills for treating lesions around the parasellar area.
