Trigeminal neuralgia is caused by compression of trigeminal nerve root and it leads to demyelination gradually. It was almost idiopathic and occurred unexpected. The upper cervical spinal cord contains the spinal trigeminal tract and nucleus. Fibers with cell bodies in the trigeminal ganglion enter in the upper pons and descend caudally to C2 level. We experienced a rare patient with facial pain, which was paroxysmal attack with severe pain after a clear event, cervical spinal injury (C2). So, this case reminds us of a possible cause of trigeminal neuralgia after a trauma of the head and neck.

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.

PURPOSE: To report a case of abducens nerve palsy after a percutaneous nerve blocking procedure for trigeminal neuralgia. CASE SUMMARY: A 35-year-old female complaining of stabbing pain in the right maxillary area 4 months in duration was diagnosed with trigeminal neuralgia at a pain clinic. The patient underwent a percutaneous trigeminal nerve blocking procedure using alcohol at the right maxillary nerve. After the procedure, the patient was referred to an ophthalmologic service for horizontal diplopia and abduction defect of her right eye. Her corrected visual acuity, intraocular pressure, pupillary response, anterior segment and fundus were normal bilaterally. The patient had right esotropia of 38 prism diopters in primary gaze (70 prism diopters in right gaze, 20 prism diopters in left gaze) with limited abduction of -3 in the right eye. She was diagnosed with abducens nerve palsy of the right eye. Three months after initial presentation, the patient had intermittent esotropia of 4 prism diopters at right gaze and orthophoria at the other diagnostic gazes; she presented no diplopia. CONCLUSIONS: In the present case study, abducens nerve palsy following a percutaneous trigeminal nerve blocking procedure resolved over 3 months. Because the abducens nerve is adjacent to the trigeminal nerve near the foramen ovale based on anatomical structure, when performing a percutaneous trigeminal blocking procedure, the surgeon should be aware that deep needle puncture could cause abducens nerve palsy.

Recently microvascular decompressive approach to the hyperactive type of low cranial nerves dysfunction has been popular procedures in neurosurgical operation. The neurosurgical teams at St. Paul's Hospital, Catholic Medical College operated on 11 patients employing this technique for 2 years. The patients were diagnosed as 9 patients with hemifacial spasm, one with trigeminal neuralgia, and one with glossopharyngeal neuralgia. The results were very encouraging of the 10 patients. But remaining one patient was failed with therapy. The authors would like to share with you their experiences employing the microvascular surgical technique, the results & the prognosis.

OBJECTIVE: Combined hyperative dysfunction syndrome (HDS) defined as the combination of HDSs such as trigeminal neuralgia (TN), hemifacial spasm (HFS) and glossopharyngeal neuralgia (GPN), which may or may not occur simultaneously on one or both sides. We reviewed patients with combined HDS and demonstrated their demographic characteristics by comparing them with those of patients with a single HDS. METHODS: Between October 1994 and February 2006, we retrospectively studied a series of 1,720 patients who suffered from HDS and found 51 patients with combined HDSs. We analyzed several independent variables in order to evaluate the prevalence and etiologic factors of combined HDS. RESULTS: The combined HDS group accounted for 51 of 1,720 (2.97%) patients with HDS; 27 cases of bilateral HFS, 10 cases of bilateral TN and 14 cases of HFS with TN. Their mean age was 52.1 years (range, 26-79 years). There were 5 men and 46 women. Seven patients had synchronous and 44 patients metachronous onset of HDSs. By comparison of combined and single HDS groups, we found that age and hypertension were closely associated with the prevalence of combined HDS (p < 0.05). CONCLUSION: This study revealed that combined HDS was very rare. Hypertension and age might be the most important causative factors to evoke combined HDS.

Tolosa-Hunt syndrome is a rare self-limiting disease that's characterized by painful ophthalmoplegia. It has a relapsing and remitting course, and the pain responds promptly to systemic corticosteroid therapy. Yet it is diagnosed by the exclusion of other major causes involving the superior orbital fissure or cavernous sinus, including trauma, neoplasm, aneurysm and inflammation. Further, the associated ophthalmoplegia may follow days to weeks after the onset of orbital or hemifacial pain. Hence, this condition is often misdiagnosed as atypical facial pain, and so improper management could result in unnecessary suffering of the patient. The following case describes a patient suffering with hemifacial pain associated with ipsilateral abducens nerve palsy, which was evident 2 weeks after the onset of pain, and this was misdiagnosed as trigeminal neuralgia and atypical facial pain.

Trigeminal neuralgia (TGN) is a relatively well-known disorder with characteristic brief attacks of shooting pain in the facial regions. Atypical signs like constant pain and/or sensory abnormalities can develop as the disease progresses. Some cases begin with atypical signs and later develop all the hallmarks of TGN. The atypical forms of TGN can be misdiagnosed as other pain disorders. We present a patient with facial pain who demonstrated a transformation in signs of glossopharyngeal neuralgia into typical trigeminal neuralgia. A 71 year-old man was referred for sharp episodic pain in his right side of the face and neck. The pain was mainly in the neck, which was worsened especially by swallowing. The condition was initially diagnosed as a glossopharyngenl neuralgia. While controlling the pain conservatively with a sympathetic blockade, the neck pain disappeared suddenly and lower jaw pain triggered by speaking and chewing became prominent, which are the characteristic signs of trigeminal neuralgia.

OBJECTIVE: The purpose of this study is to review the surgical results of 19 patients with idiopathic trigeminal neuralgia treated by percutaneous ballooning compression(PBC) of trigeminal gasserian ganglion under brief general anesthesia. METHODS: The mean patient age was 63.5 years(range, 27-78). The mean follow-up period was 24 months(range, 1-46). Three patients had already undergone radiofreqnency trigeminal rhizotomy and two patients had previously microvascular decompression. The balloon was inflated by injecting radio-contrast media 0.7-1cc in amount. The mean inflating time is 81 seconds(range, 60-90). RESULTS: During the procedure, brief intraoperative bradycardia and hypotension were noted in seven cases(36.7%). All patients had immediate relief of pain except 1 case. 18 cases(94.5%) of patients were satisfied or very satisfied with their pain relief. There were immediate, mild to moderate sensory complication of hypesthesia, dysesthesia or paraesthesia in all cases and the immediate motor complication-difficulty of mastication in 3 cases, transient 6th nerve palsy in 2 cases. The immediate motor and sensory complications disappeared or much improved after 3-4 months. CONCLUSION: It is the simple technique that can be performed effectively in a brief period of general anesthesia. This procedure might be one of attractive methods in the treatment of idiopathic trigeminal neuralgia.

Trigeminal neuropathy os characterized by unremitting facial pain, no evident trigger point and facial sensory change. According to Jannetta, in trigeminal neuropathy, the offending artery is not necessarily in contact with the root entry zone(REZ) but any site of the nerve. We have recently experienced a 48-year-old woman with symptoms and signs compatible with trigeminal neuropathy and explored the CP angle. SCA was crossing just anterior to the trigeminal root and one small arterial loop was lying on the pons close to the root entry zone(REZ) but neither of them was in diirect contact with the nerve. Teflon felt was inserted between the arteries and nerve and secured with silk and beriplast for fear that they should contact by changing position. Immediately after the operation the facial pain and pre-existing facial sensory change were completely gone.

Teflon(polytetrafluoroethylene) felt it utilized well as an implanted material for suboccipital microvascular decompression of hemifacial spasm, trigeminal neuralgia and glossopharyngeal neuralgia. Although the effect of Teflon has been studied widely, there are no studies about the effect on the cerebral vessels. The authors have examined the porribilities of the change of cat cerebral vessels and femoral vessels by direct contact the Teflon. There was no changes of vessel wall. Also the authors couldn't find any aneurismal changes of vessels wall. Teflon han only effect of foreign body reaction. This experiment shows that Teflon is relatively inert when used for microvascular decompression.
