Subarachnoid hemorrhage secondary to rupture of an aneurysm is a severe condition, associated with a high rate of morbidity and mortality. There are few cases in the literature of rupture of an aneurysm of the persistent trigeminal artery. This is the case of a 62-year-old female who has suffered multiple ruptures of aneurysms, in different decades of her life, with the development of de novo aneurysm, been this the presented case, a rupture of aneurysm of the persistent trigeminal artery. This patient has survival to these conditions and remain without important morbidity. The case manifested with a clinical picture of third and seventh cranial nerve deficit, which this last one, there are not previous publications of cases with this deficit. This aneurysm was embolized with coils, and the postoperative condition was satisfactory, been discharged at 4 postoperative days.

Objectives : To understand spatial cause hypothesis of idiopathic trigeminal neuralgia, the body truncus area was divided into intracranial, thoracic and pelvic cavity and was illustrated, the subjective pain degrees of idiopathic trigeminal neuralgia were compared with the illustraion of three cavity. Methods : The frontal view of pictures of idiopathic trigeminal neuralgia subject truncus area were illustrated into three circles which was treated with conservative methods like the pelvic correction, cervical correction, FCST, posture training without drugs and acupuncture. The spatial analysis of three circle vertical centerlines were compared with the pain degrees. Results : The vertical centerlines of three circles were agreed with the body gravity centerline depending on the treatment progresses. namely, as the parts of truncus were matched to the body gravity centerline, the degrees of pain were decreased. Conclusions : The vascular pressure on the trigeminal nerve which was causing the idiopathic trigeminal neuralgia might be induced by the spatial misalignment of truncus area because the spatial misalignment of it can press to move vascular into trigeminal nerve partially. Further study will be progressed.

Neurogenic muscular atrophy is muscle wasting and weakness caused by trauma or disease of the nerve that innervates the muscle. We describe a case of unilateral trigeminal neuropathy and neurogenic muscular atrophy of the masticatory muscle caused by a tumor in the foramen ovale. A 59-year-old man visited our clinic complaining of difficulty in right-sided mastication. There were no evident clinical signs and symptoms of temporomandibular disorder. However, severe atrophy of the right masseter and temporalis muscles and hypesthesia of the right side mandibular nerve area were confirmed. Through T1 and T2 signals on magnetic resonance imaging (MRI), a mass suspected of a neurogenic tumor was observed in the foramen ovale and cavernous sinus. Severe atrophy of all masticatory muscles on the right side was observed. This rare case shows trigeminal neuropathy caused by a tumor around the foramen ovale and atrophy of the ipsilateral masticatory muscles. For an accurate diagnosis, it is essential to identify the underlying cause of muscle atrophy with neurologic symptoms present. This can be done through a more detailed clinical examination, including sensory testing and brain MRI, and consider a referral to neurology or neurosurgery for the differential diagnosis of the intracranial disorder.

This study evaluated a case of trigeminal nerve stimulation during acupotomy at a site 5 pun left of GV16. The study participant was a 52-year-old male suffering from upper neck pain and numbness, which was managed by acupotomy at a site 5 pun left of GV16. During acupotomy, the patient experienced unexpected numbness and stiffness of the left zygomatic bone. This area corresponds to the distribution of the maxillary nerve, which is the second branch of the trigeminal nerve. After approximately one month, symptoms of numbness and stiffness disappeared without rendering medical treatment. These side effects are presumed to be associated with the trigeminocervical complex and stimulation of the trigeminal nucleus within the spinal cord. Thus, during the acupotomy of the upper neck, especially at GV16, the needles should be inserted slowly, and the patient's response should also be monitored.

Trigeminal nerve functions movement and sensation on orofacial region. Therefore, it is very important in dental clinic. Neurons with their cell bodies in trigeminal ganglion of trigeminal nerve root are primary sensory neurons and playa role of tactile sense, pressure, vibration and pain of orofacial area. Transmission of these senses depends on ion channels, we know that trigeminal ganglion neuron exists many kind of ion channels. Methods of definition on ion channel are several, but in this study we use immunostaining for detection of ion channels.(omitted)

This study was carried out to investigate the pathogenesis of canine herpesvirus(CHV) infection in dogs. The 17 puppies, one day old, delivered from CHV seronegative 3 dams were divided into two groups. The 13 puppies were inoculated intranasally with 1ml of CHV-KK inoculum($5{\times}10^{5.6}TCID_{50}/ml$) and 4 puppies were served as control. And then the puppies were sacrificed at 2, 4, 6 and 7 days after the treatment, and collected blood, nasal mucosa, trigeminal nerve, trigeminal ganglion, bone marrow, eye, brain and other major organs. These organs were examined histopathologically and electron microscopically. The platelets of puppies infected with CHV were dramatically decreased because of the damages of vascular endothelial cells. Histopathologically, necrotizing vasculitis and neuritis were proceeded the generalized focal necrosis of all organs. Necrotic changes in trigeminal ganglion, trigeminal nerve and ventroposteriomedial nucleus of thalamus were observed in 4 puppies infected with CHV. Herpesviral particles, various forms of maturation, were observed in endothelial cells of the alveolar capillary and hepatic sinusoid with electron microscopy. These results suggest that the generalized focal necrcsis of all organs including brain and eyes in canine herpesvirus infection were resulted from generalized vasculitis, and also the hemonecrotizing meningoencephalitis was related to the necrosis of trigeminal nerve pathway.

The aim of the present study was to examine the effects of preemptive analgesia on the development of trigeminal neuropathic pain. For this purpose, mechanical allodynia was evaluated in male Sprague-Dawley rats using chronic constriction injury of the infraorbital nerve (CCI-ION) and perineural application of 2% QX-314 to the infraorbital nerve. CCI-ION produced severe mechanical allodynia, which was maintained until postoperative day (POD) 30. An immediate single application of 2% QX-314 to the infraorbital nerve following CCI-ION significantly reduced neuropathic mechanical allodynia. Immediate double application of QX-314 produced a greater attenuation of mechanical allodynia than a single application of QX-314. Immediate double application of 2% QX-314 reduced the CCI-ION-induced upregulation of GFAP and p-p38 expression in the trigeminal ganglion. The upregulated p-p38 expression was co-localized with NeuN, a neuronal cell marker. We also investigated the role of voltage-gated sodium channels (Navs) in the antinociception produced by preemptive application of QX-314 through analysis of the changes in Nav expression in the trigeminal ganglion following CCI-ION. Preemptive application of QX-314 significantly reduced the upregulation of Nav1.3, 1.7, and 1.9 produced by CCI-ION. These results suggest that long-lasting blockade of the transmission of pain signaling inhibits the development of neuropathic pain through the regulation of Nav isoform expression in the trigeminal ganglion. Importantly, these results provide a potential preemptive therapeutic strategy for the treatment of neuropathic pain after nerve injury.

Objective : The purpose of this study is to evaluate the clinical characteristics and surgical outcome of cerebellopontine angle (CPA) epidermoids presenting with trigeminal neuralgia. Methods : Between 1996 and 2004, 10 patients with typical symptoms of trigeminal neuralgia were found to have cerebellopontine angle epidermoids and treated surgically at our hospital. We retrospectively analyzed the clinico-radiological records of the patients. Results : Total resection was done in 6 patients (60%). Surgical removal of tumor and microvascular decompression of the trigeminal nerve were performed simultaneously in one case. One patient died due to postoperative aseptic meningitis. The others showed total relief from pain. During follow-up, no patients experienced recurrence of their trigeminal neuralgia (TN). Conclusion : The clinical features of TN from CPA epidermoids are characterized by symptom onset at a younger age compared to TN from vascular causes. In addition to removal of the tumor, the possibility of vascular compression at the root entry zone of the trigeminal nerve should be kept in mind. If it exists, a microvascular decompression (MVD) should be performed. Recurrence of tumor is rare in both total and subtotal removal cases, but long-term follow-up is required.

Background: Damages of trigeminal nerve, particularly inferior alveolar nerve and lingual nerve, could occur following dental procedures. In some cases, nerve damage may happen as a complication of the local anesthetic injection itself and not of the surgical procedure. Methods: From September 2006 to August 2010, 5 cases of inferior alveolar nerve and lingual nerve damages, which were assumed to happen solely due to local anesthesia, were reviewed. All cases were referred to Division of Oral and Maxillofacial Surgery, Department of Dentistry, Hanyang University Medical Center for legal authentication in the process of criminal procedure. Results: In all five cases, patients complained of altered sensation occurred in the distribution of the inferior alveolar or lingual nerve following block anesthesia. The local anesthetics were 2% lidocaine with 1 : 100,000 epinephrine and the amount of local anesthetics, which were used during injection, were varied. Most of patients experienced the electric stimulation during injection. Recovery was poor and professional supportive care was mostly absent. Conclusions: Dental practitioners should consider that the surgical procedure caused the trigeminal nerve damage, however, dental local anesthesia for inferior alveolar nerve and lingual nerve could be one of the causes for damages. The various mechanisms for nerve damages by local anesthesia are thoroughly discussed.
