Among the distal anterior inferior cerebellar artery (AICA) aneurysms, a unique aneurysm at the meatal loop inside the internal auditory meatus is extremely rare. The authors report a case of surgically treated total intrameatal AICA aneurysm. A 62-year-old female patient presenting with sudden bursting headache and neck pain was transferred to our department. Computed tomography and digital subtraction angiography showed subarachnoid hemorrhage at the basal, prepontine cistern and an aneurysm of the distal anterior inferior cerebellar artery inside the internal auditory meatus. Surgery was performed by retrosigmoid craniotomy with unroofing of the internal auditory meatus. The aneurysm was identified between the seventh and eighth cranial nerve in the meatus and was removed from the canal and clipped with a small straight Sugita clip. After operation the patient experienced transient facial paresis and tinnitus but improved during follow up.

Sudden headache onset may rarely be caused by spontaneous intracranial hypotension (SIH). Other associated symptoms in patients with SIH are nausea, vomiting, vertigo, hearing alteration, and visual disturbance. This case report describes a 43-year-old female diagnosed with SIH who developed diplopia after resolution of an abrupt-onset headache, which was managed with conservative treatments, including bed rest and hydration. She was also diagnosed with secondary right sixth cranial nerve palsy. Although conservative management relieved her headache, the diplopia was not fully relieved. Application of an autologous epidural blood patch successfully relieved her diplopia, even after 14 days from the onset of visual impairment.

Neurilemmoma is a benign tumor of the nerve sheath that arises on cranial and spinal nerve roots as well as along the course of peripheral nerves. A case of a neurilemmoma that arose in the left infratemporal fossa of a 29-year-old male was presented. Plain radiographs, enhanced computed tomography scan, and magnetic resonance imaging demonstrated a large, well-circumscribed, heterogeneously enhanced mass with extension into the pterygopalatine fossa. Displaced by the large mass, bowing-in of the posterior maxillary antral wall was noted and a provisional diagnosis of a benign soft tissue tumor was made. The mass was completely excised and a diagnosis of neurilemmoma was confirmed.

Ramsay Hunt syndrome is a viral associated disease with severe otalgia, vertigo, fever, herpetic eruptions on either side of the external auditory meatus and cavum concha, ipsilateral facial nerve palsy and cochleovestibular dysfunction. This syndrome may be the most common cause of unilateral facial paralysis and involvement of both the vestibular and cochlear branch of 8th cranial nerve. And loss of taste sensation may be developed in same involement site. This syndrome affects adults in most cases, and a samll number of children with herpes zoster oticus have been reported. And concomittantly CNS invlovement of this snydrome is very rare. We experienced a 7 years old aged patient of Ramsay Hunt syndrome who had evidence of aseptic meningitis, and this patient showed well reponses with Acyclovir and symptomatic therapy. So, we report this case with brief review of related literatures.

Objective : To determine the feasibility of translabyrinthine approach in the vestibular schwannoma patients, the authors reviewed eighteen consecutive cases, focusing at their functional outcome and operative complications. Materials and Method : To evaluate the functional outcome, we reviewed preoperative radiological findings such as size of tumors and location of jugular bulb as well as the preoperative neurological status including audiometric analysis and cranial nerve function in 18 patients, diagnosed as vestibular schwannoma. Also the surgical outcome was evaluated according to the functional preservation of facial nerve and incidence of the surgical complication as well as the extent of surgical resection. Results : The age of patients ranged from 21 to 62 years, with a mean of 50 years. Of 18 patients operated in our center by the translabyrinthine approach, wide exposure with total removal of the mass was possible in 16 cases (88.8%). The facial nerve was anatomically preserved in 88.8%. At six-month follow-up, facial nerve function was good(Grade I-II) in 15 patients(83%) and acceptable(I-IV) in all patients. Although the jugular bulb was highly placed is five patients, gross total resection was possible without facial nerve injury in all patients by the translabyrinthine approach. One patient experienced CSF leakage after surgery, but there was no patient with disabling deficit. Conclusion : Use of the translabyrinthine approach for removal of vestibular schwannomas resulted in good anatomical and functional preservation of the facial nerve, with minimal incidence of morbidity and no mortality. In cases of high jugular bulb impacted into mastoid bone, total removal was possible by displacing the jugular bulb with Surgicel cellulose and placement of bone wax.

Objective: Facial nerve palsy is caused by damage to the seventh cranial nerve. It is the main symptom of facial muscle paralysis on the affected side. If the patient cannot receive proper treatment, severe permanent impairments, both physical and mental, may result, so this disease must be treated appropriately. In this study, a patient with facial nerve palsy was admitted to a Korean medicine hospital for treatment. This case study reports on the patient's progress and the effects of the treatment. Methods: We treated the patient with herbal medicines, acupuncture, herbal acupuncture therapy, and physical therapy. The House-Brackmann Grading System and a weighted regional grading system were used to assess symptom changes. Results: The patient with facial nerve palsy was hospitalized for 50 days and recovered from symptoms without significant problems in the face or to motor function. Conclusion: This case report demonstrates the possibility of treating facial nerve palsy using Korean medicine.

Purpose: Herpes zoster is a common dermatologic disease characterized by unilateral pain and vesicular lesions over the unilateral sensory dermatomes being caused by the reactivation of Varicella zoster virus and its incidence seems to be increasing recently. In case of involving the ganglion of the fifth cranial nerve(trigeminal nerve), it can descend down the affected nerve into skin, then producing an eruption in the dermatome. Among the patients, about 40 - 50% had associated conditions such as diabetes mellitus, hypertension, pulmonary tuberculosis, liver diseases, peptic ulcer, hypothyroidism, pharyngitis but rare facial trauma. Methods: Retrospective study was done for 3 cases of Herpes zoster from May 2000 to May 2007, which had been treated with acyclovir and steroid. Results: The clinical course was uneventful. Follow-up length was about 3 months. After treatment, the patients became stable and there was no complications. Conclusion: Herpes zoster was commonly associated with systemic disorders and the treatment duration was prolonged in associated diseases. But herpes zoster occurring specifically at the site of previously traumatized facial skin has not yet been reported. We experienced the treatment of herpes zoster developing within recent operative facial scar and three cases are presented with the review of literatures. Finally, facial trauma might be a risk factor for herpes zoster in traumatized patients.

Objectives : Bell's palsy in an acute peripheral facial nerve paralysis that usually affects only one side of the face. The seventh cranial nerve carries predominantly motor fibers, but also supplies some autonomic innervation, sensation to park of the ear, and taste to the anterior two thirds of the tongue. The aim of this study is to provide evidence of differences between facial skin temperature of the paralyzed side and normal side in Bell's palsy patients. Methods : the author studied 68 patients with Bell's palsy whose facial nerve function had been documented by the House-Brackmann grading system. We measured skin temperature of the forehead, zygoma, lower lip, temple and lower jaw area of the paralyzed side and those of the normal side. Results : there were significant facial skin temperature differences between the forehead area of paralyzed side and that of normal side of GrII(P<0.05) and III(P<0.05). The result also showed that the facial skin temperature difference according to the aflection period vanished when air temperature was calibrated (F=1.700, P=0.178). Conclusions : Thermography is a useful diagnostic tool in Bell's palsy if the air temperature is low enough to cool the facial skin temperature and the forehead area is evaluated as the sampling zone.

Background and purpose: Bell‘s Palsy is a condition that causes the facial muscles to weaken or become paralyzed. It's caused by trauma to the 7th cranial nerve, and is not permanent. The aim of this study is to be convinced of differences between facial electrodermal activities of paralyzed side and those of normal side in acute stage of Bell's Palsy patients Methods: Electrodermal activity (EDA) was performed within 1 week after the onset of facial palsy and facial nerve electromyography (EMG) at 2 weeks after the onset. The recovery of facial nerve function was documented by House and Brackmann grading. All the patients were followed up weekly until recovery or up to 6 weeks. Results: There was significant differences (conductivity A: t=3.319, p=0.002; conductivity C: t=2.699, p=0.010) between facial electrodermal conductivities of paralyzed side and those of normal side in acute stage of Bell's Palsy patients (N=45). And the result showed that logarithmic scale of electrodermal conductivity A value ratio obviousely decreased with logarithmic scale of EMG zygomatic branch amplitude ratio (r=-0.472, p=0.143); logarithmic scale of capacitance B, logarithmic scale of EMG temporal branch amplitude ratio (r=-0.422, p=0.133); logarithmic scale of conductivity C, logarithmic scale of EMG buccal branch amplitude ratio (r=-0.545, p=0.083) (N=12). Conclusion: Electrodermal conductivities increased in paralyzed facial side in acute stage of Bell's Palsy patients.

Technological advances of mankind, through the development of electrical and communication technologies, have resulted in the exposure to artificial electromagnetic fields (EMF). Technological growth is expected to continue; as such, the amount of EMF exposure will continue to increase steadily. In particular, the use-time of smart phones, that have become a necessity for modern people, is steadily increasing. Social concerns and interest in the impact on the cranial nervous system are increased when considering the area where the mobile phone is used. However, before discussing possible effects of radiofrequency-electromagnetic field (RF-EMF) on the human body, several factors must be investigated about the influence of EMFs at the level of research using in vitro or animal models. Scientific studies on the mechanism of biological effects are also required. It has been found that RF-EMF can induce changes in central nervous system nerve cells, including neuronal cell apoptosis, changes in the function of the nerve myelin and ion channels; furthermore, RF-EMF act as a stress source in living creatures. The possible biological effects of RF-EMF exposure have not yet been proven, and there are insufficient data on biological hazards to provide a clear answer to possible health risks. Therefore, it is necessary to study the biological response to RF-EMF in consideration of the comprehensive exposure with regard to the use of various devices by individuals. In this review, we summarize the possible biological effects of RF-EMF exposure.
