Trigeminal sensory neuropathy is a clinical diagnosis in which the main feature is facial numbness limited to territory of one or more sensory branches of the trigeminal nerve. We describe a 46-year-old woman who presented with left facial numbness in the territories of maxillary nerve and mandibular nerve. MRI disclosed a lesion in left trigeminal nerve root entry zone. In Blink test stimulating infraorbital foramen, ipsilateral R1 was delayed compared with contralateral R1. Lesion in pons or medulla can present as trigeminal sensory neuropathy.

We have few assessment tool in physical therapy. Recently, there is increasingly a concern of electrophysiologic examinations. They includes electomyography; needle and surface, evoked potentials; somatosensory evoked potentials; brainstem auditory evoked potentials; visual evoked potentials, nerve conduction velocity, blink reflex, H-reflex, and F-wave. The purpose of this study is understanding of electrophysiologic examinations. So we hope many physical therapist to use electrophysiologic examinations in research.

Hemifacial spasm (HFS) may develop after Bell's palsy (BP). But it was not reported that contralateral HFS occurred simultaneously in acute BP. A 25-year-old woman admitted with left HFS occurred simultaneously in acute right BP for 6 days. Past, family, and social history were unremarkable. Nerve conduction studies (NCS) and blink reflex (BR) test showed bilateral facial neuropathies. Brain MRI and cerebral angiography were normal. The symptoms and signs of HFS and BP were improved slowly after acyclovir and prednisolone therapy. Follow-up serial NCS and BR also showed a rapid improvement.

A 25-years-old woman with mandibular prognathism underwent a mandibular setback by way of mandibular sagittal split ramus osteotomy (MSSRO). After 2 days of operation, she developed difficulty of closing her right eye. The blink reflex test and motor nerve conduction study of the right orbicularis oris muscle were revealed right facial neuropathy of unknown origin and House-Brackmann facial nerve grading system (HBFNGS) grade V. For treatment, we initially prescribed oral prednisolone and nimodipine including physical therapy. The samples consisted of 11 facial nerve palsy patients caused by MSSRO and were analysed about onset of facial nerve palsy, postoperative HBFNGS, final HBFNGS, treatment method and recovery time. At 10 weeks of treatment of nimodipine, she had completely regained normal function (HBFNGS grade I) of the right facial nerve. The clinical results lead to assume a fast recovery of facial nerve function by the nimodipine medication, whereas average time of recovery is 16.32 weeks in references. Despite of the limited one patient treated, the result was very promising with respect to a faster recovery of the facial nerve function. Considering the use of nimodipine treatment for peripheral facial nerve palsy following a surgical approach with an anatomically preserved nerve can be recommended.

Miller Fisher syndrome(MFS) has been the focus of conflicting opinions regarding the peripheral versus the central nature of the site of major neural injury. We present our electrophysiological findings in one case of MFS to help clarify the pattern of peripheral nerve injury in this syndrome. A 45-year-old man visited our hospital due to sudden diplopia. Initial examination revealed internuclear opthalmoplegia. The next day, his symptoms rapidly aggravated to complete external ophthalmoplegia, ataxia, and areflexia with hand and foot numbness. Serial electrophysiological studies were performed. The results of brainstem evoked potential(BAEP) and blink reflex were normal in the serial studies. Motor and sensory nerve conduction study(NCS) were normal findings in second hospital day, but ulnar sensory nerve shows no sensory nerve action potential(SNAP) and sural sensory conduction velocity was delayed in 7th hospital day. Our patient's clinical presentation began to improve on 15th hospital day, and his electrophysiologic study showed improvement on 29th hospital day. We believe that all the manifestations of MFS can be explained by the involvement of peripheral nerves without brainstem or cerebellar lesion with the serial electrophysiological studies.

Background : Bell's palsy(BP) is defined as an idiopathic peripheral facial paralysis of sudden onset and account more than 50% of facial paralysis. It's etiology is unclear, but herpes simplex virus type-1(HSV-1) has been the most suspicious causative agent of BP that ever been studied. We evaluated the effect of add-on acyclovir in acute stage of BP. Methods : Subject consisted of 35 patients who developed acute idiopathic unilateral facial nerve palsy(16 men and 19 women with age 9-78 years old). The treatments were started within 10 days after onset of BP. Facial nerve function was assessed by the House-Brackman facial nerve grading scale and facial nerve conduction study including blink reflex. Follow-up evaluation were made 2 month after onset. Twenty of 35 patients were treated with combined therapy of acyclovir and prednisone. As a control group, 15 patients were treated with prednisone only. We compared the improvement of neurologic defects at recovery phase. Results : Compared with two groups, difference in grading scale at recovery phase is statistically significant(p<0.01). So, acyclovir-prednisone group showed a significant improvement in grading scale at recovery phase compared with prednisone group. Conclusion : We identified the benefits of add-on acyclovir in the acute stage of BP.

Background: Miller-Fisher syndrome (MFS) is characterized by the clinical triad of ophthalmoplegia, ataxia, and areflexia, and is considered a variant form of Guillain-Barre syndrome. Although some cases of delayed-onset facial palsy in MFS have been reported, the characteristics of this facial palsy are poorly described in the literature. Methods: Between 2007 and 2010, six patients with MFS were seen at our hospital. Delayed facial palsy, defined as a facial palsy that developed while the other symptoms of MFS began to improve following intravenous immunoglobulin treatment, was confirmed in four patients. The clinical and electrophysiological characteristics of delayed facial palsy in MFS, as observed in these patients, are described here. Results: Four patients with delayed-onset facial palsy were included. Delayed facial palsy developed 8-16 days after initial symptom onset (5-9 days after treatment). Unilateral facial palsy occurred in three patients and asymmetric facial diplegia in one patient. The House-Brackmann score of facial palsy was grade III in one patient, IV in two patients, and V in one patient. None of the patients complained of posterior auricular pain. Facial nerve conduction studies revealed normal amplitude in all four patients. The blink reflex showed abnormal prolongation in two patients and the absence of action potential formation in two patients. Facial palsy resolved completely in all four patients within 3 months. Conclusions: Delayed facial palsy is a frequent symptom in MFS and resolves completely without additional treatment. Thus, standard treatment and patient reassurance are sufficient in most cases.

A 4-year-old Thoroughbred gelding was referred to Chonbuk National University Animal Medical Center with inability to blink and drooping lower lip on the right side after traumatic accident. Through clinical examination, the horse was diagnosed as right-sided facial nerve paralysis. Acupuncture treatment was performed to treat the facial nerve paralysis. The selected acupoints were ST3, ST5, ST7, ST9, SI17, CV24 and Yintang. At the end of the $2^{nd}$ weeks of electroacupuncture treatment, the palpebral reflex was normally recovered. One month after the therapy, symmetry of the face was completely accomplished without the drooping lower lip. This case shows that electroacupuncture should be considered as an effective therapy for the traumatic facial nerve paralysis in horse.

Background: Bell's palsy (BP) is a self-limited rapid onset facial palsy that is non-life-threatening and has a generally favorable prognosis. Facial paralysis can be caused by numerous conditions, all of which should be excluded before the diagnosis of BP is reached. The etiopathogenesis and clinical course of BP are uncertain. So we analyzed the epidemiology and clinical course of BP patients. Methods: The subjects include 100 cases of BP examined during the period of 18 months. Careful clinical history, neurologic examinations, laboratory tests, electrophysiologic studies, and brain imaging were performed. Follow-up examinations were done once a week during the first month and subsequently once a month until normal function was restored or for up to 3 months. Facial nerve function was assessed by House-Brackman (HB) facial nerve grading scale and electrophysiologic studies. Results: Except 13 recurrent BP patients, we analyzed 87 BP patients. Forty-four (50.6%) were men and 43(49.4%) were women and the mean age was 51.0(${\pm}16.6$) years. Three (3.4%) patients showed a familial tendency. The initial examination within 1 week after attack revealed 35.2% was below HB grade 4 and 64.8% was above grade 3. The associated symptoms are as follows; postauricular pain, increase tear flow, taste change, hyperacusis and drooling. The initial facial nerve conduction study and blink reflex within 1 week after attack showed abnormal findings in 12.6% and 100%, respectively. Brain MRI was performed in 59(67.8%) patients and showed abnormal enhancement of affected nerve in 57(96.6%). Follow-up examination showed that 78.2% of the patients partially improved within 4 weeks and completely improved within 3 months. Finally 80.5% of the total patients obtained normal function in 3 months. Conclusions: We report epidemiologic, clinical, electrophysiologic and radiologic characteristics of BP patients.
