This study aimed to evaluate pain assessment strategies and factors associated with outcomes after microvascular decompression for the treatment of primary trigeminal neuralgia in adults. We conducted a systematic review and meta-analysis of English, Spanish, and French literature. We searched three databases, PubMed, Ovid, and EBSCO, from 2010 to 2022 and selected studies including patients with primary trigeminal neuralgia, clear pain assessment, and pain outcomes. Population means and standard deviations were calculated. Studies that included factors associated with postoperative outcomes were included in the meta-analysis. A total of 995 studies involving 5673 patients with primary trigeminal neuralgia following microvascular decompression were included. Patients with arteries compressing the trigeminal nerve demonstrated optimal outcomes following microvascular decompression (odds ratio [OR]= 0.39; 95% confidence interval [CI] = 0.19-0.80; X² = 46.31; Dof = 15; I² = 68%; P = < 0.0001). Conversely, when comparing arterial vs venous compression of the trigeminal nerve (OR = 2.72; 95% CI = 1.16-6.38; X² = 23.23; Dof = 10; I² = 57%; P = 0.01), venous compression demonstrated poor outcomes after microvascular decompression. Additionally, when comparing single-vessel vs multiple-vessel compression (OR = 2.72; 95% CI = 1.18-6.25; X² = 21.17; Dof = 9; I² = 57%; P = 0.01), patients demonstrated unfavorable outcomes after microvascular decompression. This systematic review and meta-analysis evaluated factors associated with outcomes following microvascular decompression (MVD) for primary trigeminal neuralgia (PTN). Although MVD is an optimal treatment strategy for PTN, a gap exists in interpreting the results when considering the lack of evidence for most pain assessment strategies.

Objective : We retrospectively investigated the long-term results of percutaneous radiofrequency thermocoagulation (RFT) using fluoroscopic image-guidance for treatment of trigeminal neuralgia. Methods : A total of 38 patients diagnosed and treated with RFT as an idiopathic trigeminal neuralgia were investigated. To minimize the risks related to conventional technique based on cutaneous landmarks, and to eliminate the need to frequent reposition of cannula, we adopted a technique of image-guided fluoroscopic cannulation of the foramen ovale. To minimize sensory complication following thermal lesion, our target response was a generation of a lesion with mild to moderate hypalgesia rather than dense hypalgesia. Results : The immediate pain-relief was achieved in all patients underwent RFT. With mean duration of follow-up of 38.2 months (range,12-72), 11 (28.9%) experienced recurrence of pain. The mean timing of recurrence was 26.1 months (range,12-46). A 42.7% recurrence rate was estimated by Kaplan-Meier analysis for the 38 patients at 46 months; 20.2% within 2 years, 29.1% within 3 years. In the long-term, 27 patients (71%) and 6 patients (15.8%) showed Barrow Neurological Institute (BNI) score I and BNI score II responses. Three (7.9%) patients was assessed as BNI score III, 2 patients (5.3%) showed BNI score IV response. As a complication, troublesome dysesthesia occurred in 3 of 38 patients (7.9%), however, there was no permanent cranial nerve palsy or morbidity. Conclusion : These results indicates that RFT under fluoroscopic image-guided cannulation of foramen ovale is a safe, effective, and reliable means of treating trigeminal neuralgia.

Objective: This study reports the efficacy of using integrative Korean medicine treatments for a patient with facial paralysis and accompanying trigeminal neuralgia. Methods: A 45-year-old male patient with left side facial palsy and facial pain due to Bell's palsy with trigeminal neuralgia was treated with herbal medicine, acupuncture, pharmacopuncture, and cupping for 18 days. The treatment effect was evaluated by measuring the scores for the numerical rating scale (NRS) of facial pain, the House-Brackmann scale, and the Yanagihara scale. Results: After the hospital treatment, the patient's facial pain NRS score was decreased, and the House-Brackmann scale and Yanagihara scale scores improved after the administration of the Korean medicine treatments. Conclusions: The integrative Korean medicine treatments appeared to be effective in treating facial nerve palsy and associated trigeminal neuralgia.

The authors have effectively treated a case of true trigeminal neuralgia involving the 3rd branch of the 5th cranial nerve by mandibular nerve block with alcohol and Dilantin administration, and reached following results. 1. Alcohol injection has a definite value as the primary treatment of trigeminal neuralgia. 2. It is not yet to be clarified whether the effects of alcohol injection and Dilantin therapy reveal synergism. 3. Phenobarital was given as an adjuvant of Dilantin, but its effect on the painful paroxysms is questionable.

Microvascular decompression is the gold standard for the treatment of trigeminal neuralgia (TN). However, percutaneous techniques still play a role in treating patients with TN and offer several important advantages and efficiency in obtaining immediate pain relief, which is also durable in a less invasive and safe manner. Patients' preference for a less invasive method can influence the procedure they will undergo. Neurovascular conflict is not always a prerequisite for patients with TN. In addition, recurrence and failure of the previous procedure can influence the decision to follow the treatment. Therefore, indications for percutaneous procedures for TN persist when patients experience idiopathic and episodic sharp shooting pain. In this review, we provide an overview of percutaneous procedures for TN and its outcome and complication.

This report describes a case of dizziness in a patient with trigeminal neuralgia that was caused by a vestibular schwannoma. A 60-year-old man with a history of pain on his left cheek, chin, molar and tongue for 5 months was diagnosed as suffering with trigeminal neuralgia of the left mandibular nerve, and this was caused by a left vestibular schwannoma. The diagnosis of the tumor was confirmed with magnetic resonance imaging (MRI), and so gamma knife surgery was performed 1 month later. At that time, the patient had been referred to the pain clinic due to allodynia on the tongue and gingival, and hypesthesia was also present on the left half of the face. Trigeminal nerve block with dehydrogenated alcohol and stellate ganglion block with 1% mepivacaine were performed and oral medication with diphenylhydantoin was started. The symptoms were alleviated after nerve block and oral medication. Dizziness, blurred vision and ataxia then developed from the 13th hospital day. We considered the symptoms as a side effect of diphenylhydantoin and we reduced the dose of diphenylhydantoin. However, the symptoms grew worse. Another brain MRI showed a slight increase of the tumor size and a mass effect with displacement of the adjacent organs, and hydrocephalus was also noted. This case shows the importance of considering the secondary symptoms that are due to brain tumor while treating trigeminal neuralgia. The changes of the brain tumors should also be considered along with the presence of new side effects.

Objective : We assessed the surgical results of percutaneous balloon compression in 50 patients with idiopathic trigeminal neuralgia. Methods : Fifty patients with follow-up period of more than 12 months were retrospectively analyzed. The mean follow-up period was 42 months (range, 12-82). The mean age was 65.8 years (range, 27-83). Seventeen patients (34%) had other previous surgical procedures. The balloon was inflated by injecting radio-contrast media under brief general anesthesia according to Mullan’s technique. The mean inflating time was 88 seconds (range, 60-120). The whole procedure took about 20 minutes. Results : We reported excellent and good results in 70% of the cases, poor in 6% as annoying dysesthesia, recurrence in 16%, and 8% failure due to technical deficiencies. Forty-six patients (92%) were initially relieved of their pain. There were permanent motor weakness of the masseter muscle in 4% of patients and transitory diplopia in 8%. Neither anesthesia dolorosa nor keratitis occurred. Almost all patients (92%) were discharged postoperatively within two days. Conclusion : These results indicate that balloon compression would be an effective method with acceptable morbidity, technically, It can be performed rapidly and simply in the treatment of idiopathic trigeminal neuralgia.
