Blink reflex could be a useful tool to differentiate facial synkinesis as one of complications of facial neuropathy, from volitional associated movements. We had performed applied blink reflex test for 23 patients with objective evidence of hemifacial weakness in which orbicularis oculi muscle(zygomatic branch) and mentalis muscle(mandibular branch) are electrophysiologically evaluated in response to supraorbital stimulation of trigeminal nerve. For an unaffected side of face there is no evidence of positive blink reflex from the mentalis muscle. We concluded that a positive blink reflex from mentalis muscle is almost always suggestive of chronic facial neuropathy even in clinical silence of facial synkinesis, or an aberrant reinnervation after peripheral facial neuropathy, and does not electrophysiologically correlate with the severity of facial palsy.

Recurrent Bell's palsy is a very rare case and have been reported that shows the incidence to be approximately 10 per cent in the Bell's palsy patents. It is generally accepted that facial paralysis caused by compression of the facial nerve by tumor develops slowly and has an unremitting course, however, reported cases have described the rare association of recurrent facial paralysis and intracranial tumor, and the same recovery rate. Usual symptoms of Bell's palsy include subacute facial palsy, hyperacusis on the affected side, postauricular pain on the affected side, altered sensation of taste, and partial trigeminal distribution hypesthesias. Complete resolution of symptoms is usually seen in 2-3months in $75-85\%$ of cases, with $25-35\%$ showing varying degrees of residual effects. We report a case of 4th ipsilateral recurrent Bell's palsy in a 14-year-old women, which was occurred in every winters. We treated her with acupuncture, moxibustion, herbal medication, carbon and silver spike point, and used House-Brackmnn grading system(HBGS) and the Fisch Detailed Evaluation of Facial Symmetry(DEFS) to assess the degree of paralysis in each part of face.

Although dysgeusia can occur as a consequence of stroke attacks, many physicians and patients tend to overlook it. A 50-year old woman complained of a 2-week history of abnormal sense of taste on the anterior two-thirds of right tongue. Blink reflex test demonstrated prolonged ipsilateral and contralateral R2 responses with the right supraorbital nerve stimulations, which suggest the lesion on the descending pathway. Brainstem magnetic resonance imaging (MRI) demonstrated abnormal findings in the right lower dorsal pons, anterior to 4th ventricle, lateral to inferior colliculus, and at the level of the pontomedullary junction, which was compatible with solitary tract nucleus and spinal trigeminal nucleus. Brainstem infarction should be considered in patients who have abnormal sense of taste. Additionally, blink reflex test may be helpful for the detection of central origin dysgeusia.

Objectives : The purpose of this study was to evaluate the clinical features of the epidermoid tumor of posterior fossa and to assess the surgical outcome. Methods : We reviewed the clinicoradiological records of 10 epidermoid tumor of posterior fossa, treated surgically at our hospital between 1991 and 1996. Results : The mean age of onset was 36 years old and mean duration of symptom was 5.2 years. Six were men and four were women. The location of tumors were cerebellopontine angle(CPA) 5 cases, cerebellum(Cbll)& 4th ventricle 3 cases, foramen magnum 1 case, and pineal region extended to Cbll and 4th ventricle 1 case. Common clinical features were trigeminal neuralgia in 3 cases, cerebellar signs 2 case, headache 2 cases, hemifacial spasm with deafness 1 case, cbll signs and multiple cranial nerve dysfunctions 1 case. One CPA epidermoid had no clinical symptom and sign associated with the tumor. The surgical approaches were suboccipital approach in 9 cases and one transcallosal approach to the tumor of pineal region. The extent of surgical removal was gross total resection in 5 cases and near total or subtotal resection in 5. Two patients with CPA tumor were complicated with facial paresis. One patient with tumor located in cerebellum extended into cisterna magna had postoperative vocal cord paresis. All complicated cases had severe adhesion of tumor capsule with brainstem or cranial nerve. The mean duration of follow up was 26 months. The overall outcome was improvement of symptoms and signs in 6 cases and stationary 4 cases. During follow up, imaging study was done in 7 patients and none of them had finding of tumor recurrence. Conclusion : We conclude that recurrence of tumor is rare in both total and subtotal resected cases, but long-term follow-up is required. Aggressive removal of tumor capsule that adhesed to brianstem or cranial nerve is avoided for preventing severe postoperative complication.

대상포진(Herpes Zoster:HZ)은 수두 대상포진 바이러스(Varicella Zoster virus)에 의해 야기된 속발성 또는 잠복성 감염이다. 증령에 따라 바이러스 특이적 면역 및 세포 매개 면역력이 감소하면서 바이러스가 재활성화되기 때문에, 대상포진은 주로 노년층에서 호발한다. 대상포진에 이환되면, 극심한 급성 통증이 발생하게 되고 수개월에 걸쳐서 회복하게 된다. 포진후신경통(Postherpetic neuralgia:PNH)은 대상포진의 대표적인 합병증의 하나로, 대상포진에 이환된 후 발생한 통증이 3개월 이상 회복되지 않을 때, 포진후신경통으로 진단할 수 있다. 임상적 증상으로는 주기적으로 찌르는 듯한 통증이 동반되는 타는 듯한 통증, 이질통이 발생할 수 있으며, 감각저하 또는 지각이상을 보일 수 있다. $Neurometer^{(R)}$(neuroselective sensory nerve conduction threshold: sNCT, Automated current perception threshold: CPT, neurotron incorporated. Baltimore, Maryland. 21209 U.S.A.)는 신경의 감각이상을 평가하는 데 유용하게 쓰이는 평가기구이다. 이번 증례는 포진후신경통을 주소로 내원한 환자의 치료 증례를 통해, 포진후신경통의 발생기전을 고찰해보고, 그 치료법에 대하여 알아보고, 또한 치료과정 중의 경과관찰 방법으로서 $Neurometer^{(R)}$를 이용하여, 감각이상의 평가 및 경과관찰시 지각이상에 대한 정량적인 평가를 시도하였다.

구강작열감증후군은 임상적 증상이나 검사실 소견없이 구강점막에 나타나는 작열감을 말하며 중년이후 폐경기 여성에게 높은 발생율을 보인다. 구강작열감증후군에서 보여지는 통증은 자발적이며 뚜렷한 악화요인을 보이고 있지 않다. 통증 유발과 관련해서 치과적 술식, 최근의 질환, 투약(항생제 요법)등을 포함하고 있으며, 작열감이 한 번 시작되면 수년간 지속된다. 대부분의 구강작열감 환자는 국소적 또는 전신적 요인을 가지고 있으며, 구강작열감증후군은 신경병리학적 활성화에서 기원되는 만성구강증상으로 고려할 수 있으며, 정신학적 원인에 대한 역할은 아직은 명확하지 않다. 구강작열감의 신경학적 측면에 대하여 연구가 증가하고 있고 이런 연구는 구강작열감에 중추신경계, 말초신경계가 관여함을 제시하고 있다. 그 중에 하나로 대두 되고 있는 것이 미각에서의 이상이 존재한다는 것이다. 구강작열감증후군에서 supertaster의 존재에 대해 언급하고 있으며, 이는 미각과 유해수용성 기전에 상호작용함을 제시하고 있다. 즉 중추신경계에서 미각과 구강 통증 감각이 연결되어 있고 이것은 구강작열감증후군에서 고삭신경, 설인신경수준에서 미각체계 변형에 의한 말초신경계와 중추신경계가 같이 상호 작용하여 구강작열감증후군을 발생시킴을 보여준다. 이에 본 저자는 만성구강통증으로 여겨지는 구강작열감증후군을 유발하는 요인과 병태 생리를 고찰하여 환자의 진단과 원인 지향적인 치료에 도움을 주고자 한다.

Purpose: Eczema herpeticum, caused by herpes simplex virus, is an infectious disease involving skin and internal organs. Varieties of physiologic, psychosocial, or environmental stress reactivate reservoir virus which exists in the trigeminal nerve ganglia. Authors report rare cases of nasal eczema herpeticum following corrective rhinoplasty. Methods: First case, 22-year-old female underwent corrective rhioplasty through an external approach in a local clinic. She developed progressive and painful erythema, nodules and vesicles on nose on the 9th day postoperatively. This unfamiliar lesion lead to a misdiagnosis as a bacterial infection, and had accelerated its progress to the trigeminal innervation of the nasal unit. Second case, a 23-year-old female underwent corrective rhinoplasty by external lateral osteotomy. Ten days after the surgery, disruption occurred on the external osteotomy site, and the ulceration gradually worsened. The surgeon misdiagnosed it as secondary bacterial infection and only an antibacterial agent was applied. Results: Both cases were healed effectively without any complication with proper wound dressing and antiviral therapy, and show no sequelae during an 8-month follow-up period. Conclusion: Eczema herpeticum is rare in the field of plastic surgery, but it should be kept in mind that secondary bacterial infections may lead to serious complications such as full-thickness skin loss. Thus, acknowledgement of the patient's past history regarding perioral or intraoral lesion may provide the surgeon with the possible expectancy of eczema herpeticum. Thus, if anyone develops eczema herpeticum, following facial plastic surgery, early diagnosis and immediate proper antiviral therapy will allow fast recovery without serious complications.

Background: Gabapentin is a novel anti-epileptic drug, which is used in clinical practice to treat epilepsy. This drug is also used as an analgesic in pain patients. The antinociceptive effect of this drug was assessed using the formalin test in the rat. Methods: In order to investigate the effects of gabapentin on the trigeminal nerve territory, we injected 0.5% formalin into the upper lip. Adult, male, Sprague-Dawley rats received a $50{\mu}l$ subcutaneous injection of 5% formalin into one vibrissal pad and the consequent, facial grooming behavior was monitored. Consistent with previous investigations using tile formalin model, animals exhibited biphasic nocifensive grooming (phase 1, 0-12 min; phase 2, 12-60 min). Results: The intraperitoneal administration gabapentin 5 minutes prior to the formalin injection led to a significant, dose-dependent reduction in grooming time during phase 2. In high doses, gabapentin also reduced the time of grooming during phase 1. Conclusions: The Intraperitoneal injection of gabapentin has an analgesic effect in the facial formalin rat model and this analgesic effect increases dose-dependently.
