Destruction of the gasserian ganglion can be carried out by creating a radiofrequency lesion under biplanar fluoroscopic guidance. This procedure is reserved for patients who have failed various interventions for intractable trigeminal neuralgia including retro-gasserian injection of glycerol and whose physical status otherwise precludes more invasive neuro-surgical treatments such as microvascular decompression. Radiofrequency thermocoagulation of the gasserian ganglion provides a safe method of achieving long-standing relief from trigeminal neuralgia with low risk. This technique is currently emerging worldwide as the surgical treatment of choice for trigeminal neuralgia. Recently we performed a successful radiofrequency gasserian ganglionotomy, without any complication, under fluoroscopic guidance. The procedure was successful and complete pain relief was achieved for a patient who already had treatments of various interventions including microvascular decompression but never experienced pain relief.

Background : There are several treatment of trigeminal neuralgia including Gasserian Ganglion Block. This paper retrospectively analyze the efficacy of Gasserian Ganglion Block as main treatment of trigeminal neuralgia. Methods : We studied 55 patients for followings; sex, age, duration from onset to visit, consulted mediator, causes, characteristics of pain, affected area, types of block, kinds and volume of used neurolytic agents, duration from first block to repeat block, types of repeat block, complications, if surgery was necessary after block. Results : Characteristic items of trigeminal neuralgia are similar with other studies. Mean duration of pain relief was 23 months. The duration was shortened in the repeat block. There were no significant complication. Conclusion : Considering Gasserian Ganglion Block as main treatment of trigeminal neuralgia is an effective and safe method. Therefore we would like to recommend the need to increase public awareness of trigeminal neuralgia and its possible treatment in pain clinics through mass commanication.

Various anesthetic techniques have been utilized for maxillo-mandibular fixation. We report the case of a patient with bilateral condylar and zygomatic arch fractures who had severe pulmonary dysfunction. The patient was administered bilateral image-guided Gasserian ganglion block through the foramen ovale to achieve surgical anesthesia. The technical details, advantages, and disadvantages of this rather unusual technique are discussed. The procedure could be a feasible technique when performed meticulously in cases where other approaches are deemed difficult.

When medical therapy fail to relieve pain at tolerable level for patients confirmed with trigeminal neuralgia, presence of mass lesion excluded, surgery is indicated. Innumerable surgical strategies have been attempted for the treatment of trigeminal neuralgia but only four have proven appropriate: (1)stereotactic radiofrequency gasserian ganglionotomy, (2) percutaneous glycerol gangliolysis, (3) percutaneous microcompression, (4) microvascular decompression. Radiofrequency thermocoagulation of the gasserian ganglion stems from the efforts of Sweet. This technique is the surgical treatment of choice around the world for surgical treatment for trigeminal neuralgia. Since 1986, over 14,000 cases have been reported utilizing this technique. To improve the treatment method further, an electrode with a flexible curved tip has been developed for easier and more precise electrode placement and lesion production during the thermocoagulation of gasserian ganglion. This operation was performed recently on three patients at Hallym University Hospital. using a curved tip electrode. Complete relief of pain was achieved for all patient. However, some complications were noted.

Most neoplasm of the floor of the mouth are squamous cell carcinoma. They originate from anterior midline floor of the mouth and penetrate into the sublingual gland. Invasion of the mandible is a late manifestation. Lymphatic spread is the submaxillary and subdigastric nodes and advanced lesions of them produce severe pain, The initial step in managing patients with cancer pain is the oncology therapy in the form of radiotherapy, surgery, or chemotherapy, alone or combined. When oncologic therapy is ineffective, the pain must be treated by systemic analgesic, psychologic, neurostimulating, regional analgesic,and meuroablative techniques. We successfully treated with gasserian ganglion block on the left side and mandibular nerve block on the right side with pure alcohol in the patient having severe submandibular, lower lip and tongue pain.

Radiofrequency thermocoagulation of the gasserian ganglion is a safe procedure that can be controlled well and provides satisfactory pain relief from trigeminal neuralgia with low risk. Here the authors report a case of radiofrequency thermocoagulation performed on a recurred trigeminal neuralgia patient, with particular attention to the V3 area. The patient was treated with microvascular decompression 7 years previous, which lead to untolerable side effects from carbamazepine medication. Following the paresthesia and masseter muscle contracture test at 50 Hz-0.06 volt and 2 Hz-0.5 volt respectively, RF lesionings were performed for 60 sec at $60^{\circ}C$ and 70 sec at $70^{\circ}C$. One week after the procedure, the pain was reduced with a mild hypoesthesia in the V2 area. After 6 months, the pain recurred. Therefore, we performed the same procedure again. After 8-months of follow-up, there has been no pain or complications.

The authors report the result achieved in the treatment of trigeminal neuralgia patient, especially V2 involved patient, using radiofrequency (RF) thermocoagulation of Gasserian ganglion. A 62-year old female patient had severe burning pain on right cheek usually initiating from upper molar teeth area for 10 years. She was treated with microvascular decompression operation 10 years ago. However, there was no pain relief by operation. She wanted non-surgical treatment. Therefore, we recommended RF thermocoagulation therapy. After 2 times of RF thermocoagulation, there was excellent pain relief without complications. And, for 6months follow-up, there were no pain, and no evidences of complication and recurrence.

Although the vast majority (about 70%) of patients with cancer will have pain directly related to neoplastic invasion into pain-sensitive bone and soft tissue structures,as many as 20% of the adults will have pain caused directly by cancer therapy. Treatment related pain problems are important for several reasons; their appearance may be confused with more omnious pain syndromes associated with tumor recurrence or progression that may be directly lead to death of the patient; when severe, compliance with recommandations for further therapy may be adversely affected. Now, we report a case of postsurgical pain syndrome after radical neck dissection in a patient with tonsilar cancer. The pain after radical neck dissection result from injury to the cervical plexus,cranial nerve,and cervical sympathetics. In our case, we ruled out soft tissue infection and tumor recurrence,and successfully treated with gasserian ganglion block with pure alcohol in the patient having neuropathic pain in the mandible and preauricular region after radical neck dissection.

Ramsay-Hunt syndrome is a viral disease associated with peripheral facial nerve paralysis accompany by erythematous vesicular rashs on the ear(zoster oticus) or in the mouth. Based on clinical presentations that indicated involvement of more than one ganglion, the gasserian, geniculate, petrous, accessory, jugular and second and third dorsal root ganglia comprised a chain in which inflammation of a single ganglion could extend to nearby ganglia. A 71-year-old man presented with left. peripheral facial palsy with otalgia, vesicular eruption in $V_2$, $V_3$, C2, C3 dermatome, tinnitus, and hearing loss.

선양낭포암의 두개내 침습은 매우 드물게 보고되어 있고 구개 선양낭포암이 두개내로 침습된 경우는 국내에서 보고된 바 없다. 침습 기전으로는 직접적인 침습, 신경주위 전이, 혈행성 전이 등 세 가지 경로가 알려져 있다. 본 증례는 35세 여자 환자로 우측 구개 선양낭포암으로 수술과 방사선치료를 받고 3년 10개월 후에 우측 삼차 신경의 안신경가지와 상악 신경가지 부위에 감각이상을 호소하였으나 CT상 재발소견이 보이지 않았다. 이후 우측 안검하수증과 안구마비 증세가 차례대로 발생되어 2차 수술을 받았으며, 종양이 삼차 신경을 따라 두개내 갓세르 반월신경절(Gasserian ganglion)을 거쳐 해면 정맥동과 안와내로 침습됨을 시사했다. 또한 7년 6개월 후에 측두골과 접형골 및 접형동을 통해 우측 측두엽으로 직접 침습된 소견이 발견되어 3차 수술을 받았다. 그 후 폐 전이가 진단된 상태로서, 일차 수술후 9년 5개월동안 생존하여 있다.
