Abstract Long-term results (average follow-up, 9.3 years) obtained in 1000 consecutive patients suffering from cryptogenetic (“essential”) trigeminal neuralgia treated with percutaneous thermorhizotomy are analyzed. Pain relief was obtained in 95% of the treated patients. Permanent morbidity was as follows: masseter weakness in 105 patients; oculomotor palsies in 5 patients; weakening of the corneal reflex in 197 patients, 6 of whom requested an ocular operation for keratitis; and painful dysesthesia in 52 patients, 15 of whom developed a painful anesthesia syndrome. There was a recurrence rate of 18.1%, and a correlation between postoperative sensory deficit and the cure rate was found. These results are discussed and compared to the results obtained with different techniques.

Object. Microvascular decompression (MVD) has become one of the primary treatments for typical trigeminal neuralgia (TN). Not all patients with facial pain, however, suffer from the typical form of this disease; many patients who present for surgical intervention actually have atypical TN. The authors compare the results of MVD performed for typical and atypical TN at their institution. Methods. The results of 2675 MVDs in 2264 patients were reviewed using information obtained from the department database. The authors examined immediate postoperative relief in 2003 patients with typical and 672 with atypical TN, and long-term follow-up results in patients for whom more than 5 years of follow-up data were available (969 with typical and 219 with atypical TN). Outcomes were divided into three categories: excellent, pain relief without medication; good, mild or intermittent pain controlled with low-dose medication; and poor, no or poor pain relief with large amounts of medication. The results for typical and atypical TN were compared and patient history and pain characteristics were evaluated for possible predictive factors. Conclusions. In this study, MVD for typical TN resulted in complete postoperative pain relief in 80% of patients, compared with 47% with complete relief in those with atypical TN. Significant pain relief was achieved after 97% of MVDs in patients with typical TN and after 87% of these procedures for atypical TN. When patients were followed for more than 5 years, the long-term pain relief after MVD for those with typical TN was excellent in 73% and good in an additional 7%, for an overall significant pain relief in 80% of patients. In contrast, following MVD for atypical TN, the long-term results were excellent in only 35% of cases and good in an additional 16%, for overall significant pain relief in only 51%. Memorable onset and trigger points were predictive of better postoperative pain relief in both atypical and typical TN. Preoperative sensory loss was a negative predictor for good long-term results following MVD for atypical TN.

Idiopathic Trigeminal Neuralgia

Abstract Background. We aimed to present the immediate and long term effect of percutaneous balloon compression (PBC) for idiopathic trigeminal neuralgia (ITN). Methods. ITN patients who underwent PBC for the first time in the past seven years were enrolled. Base line data and immediate postoperative outcomes were collected by reviewing the medical records and long term results. Kaplan-Meier curve, life-table analysis proportional-hazards analysis were utilized to assess the long term results and the likelihood of tic recurrence. Results. 12,797 patients were enrolled. Immediate after the PBC procedure, complete and partial pain relief were achieved in 95.6% and 1.1% patients respectively, with no relief in 1.7 % patients; the common side effects on the affected side of face included the sense loss in 98.9% patients, with 3.8% of them experienced sense loss combined abnormal sense; masseter weakness in 90.6%, herpes eruption in 51.4%, corneal reflex weakness or loss in 12.7% patients. The fewer perioperative complications covered diplopia in 139 patients (1.1%), partial hearing loss in 190 patients (1.5%), vascular complications in 5 patients (0.05%), brainstem hematoma in one patient (0.01%), ischemic stroke in two patients (0.02%), intracranial hemorrhage in 11 patents (0.09%), and intracranial infection in one patient (0.01%) patients. Of three deaths happened in the perioperative period, two died of intracranial hemorrhage, and the other one died of intracranial infection. 5794 (49.2%) patients, who were followed than one year after the procedure, were included in the follow-up study, with the median follow-up period of 7.2 years. Complete and partial pain relief were obtained in 82.9% and 6.8% patients respectively, while the pain recurrence occurred in 8.5% patients. Side effects included sense loss without abnormal sense in 54.3%, with acceptable abnormal sense in 6.0%, and with severe abnormal sense in 2.0% patients. Masseter weakness was reported by 7.5% patients. 96.4% patients were satisfied with the procedure. Conclusion. Our study shows PBC is a safe, simple and effective procedure, with both immediate and long-term success rates, acceptable side effects and fewer deadly complications, should be considered as one of the best choice for the treatment of ITN patients.

✓ There is a lack of prospective studies for the long-term results of percutaneous stereotactic radiofrequency rhizotomy (PSR) in the treatment of patients with trigeminal neuralgia. The authors present results in 154 consecutive patients with trigeminal neuralgia treated by PSR and prospectively followed for 15 years. Ninety-nine percent of the patients obtained initial pain relief after one PSR. Dysesthesia occurred in 31 patients (23%): in 7% with mild initial hypalgesia; in 15% with dense hypalgesia; and in 36% with analgesia. Dysesthesia was mild and did not require treatment in most patients. The corneal reflex was absent or depressed in 29 patients, and keratitis developed in three patients. In 19 of 22 patients with trigeminal motor weakness, the paresis resolved within 1 year. Of 33 patients who had pain recurrence, 10 patients had pain that was mild or controlled with medications, and 23 patients required additional surgical treatment. The authors estimated using Kaplan—Meier analysis that the 14-year recurrence rate was 25% in the total group: 60% in patients with mild hypalgesia, 25% in those with dense hypalgesia, and 20% in those with analgesia. Timing of pain recurrence varied according to the degree of sensory loss. All pain recurrences in patients with mild hypalgesia occurred within 4 years after surgery; 10% more of the patients with dense hypalgesia had pain recurrences within the first 10 years compared with patients with analgesia. The median pain-free survival rate was 32 months for patients with mild hypalgesia and more than 15 years for patients with either analgesia or dense hypalgesia. Of the 100 patients followed for 15 years after one or two PSR procedures, 95 patients (95%) rated the procedure excellent (77 patients) or good (18 patients). The authors conclude that PSR is an effective, safe treatment for trigeminal neuralgia. Dense hypalgesia in the painful trigger zone, rather than analgesia, should be the target lesion.

Abstract:Percutaneous retrogasserian glycerol rhizotomy (PRGR) was used during an 11-year interval in 53 patients with typical trigeminal neuralgia associated with multiple sclerosis. All patients had failed extensive medical trials prior to PRGR. Long-term (median follow-up, 36 months) complete pain relief (no further medication) was achieved in 29 (59%) of 49 evaluable patients. Eight patients (16%) had satisfactory pain control but required occasional medication. Twelve patients (25%) had initial unsatisfactory results with inadequate pain relief; nine underwent alternative surgical procedures. Sixteen patients (30%) subsequently required repeat glycerol rhizotomies to reachieve pain control. Twenty-seven patients (60% of 45 patients evaluated for this finding) retained normal trigeminal sensation after injection. Major trigeminal sensory loss developed in a single patient who had four glycerol rhizotomies over a 25-month interval. No patient developed deafferentation pain. We believe that PRGR is a low-morbidity, effective, and repeatable surgical procedure for the management of trigeminal neuralgia in the setting of multiple sclerosis.

Abstract Background and Objective Trigeminal neuralgia is a common neurologic disease that seriously impacts a patient's quality of life. We retrospectively investigated the efficacy and safety of internal neurolysis (nerve combing) for trigeminal neuralgia without vascular compression. Patients and Methods This study was a retrospective review of all patients with trigeminal neuralgia who were admitted between January 2014 and February 2019. A subgroup of 36 patients had no vascular compression at surgery and underwent internal neurolysis. Chart review and postoperative follow-up were performed to assess the overall outcomes of internal neurolysis. Results Thirty-six patients were identified, with a mean age of 44.89 ± 7.90 (rang: 31–65) years and a disease duration of 5.19 ± 2.61 years. The immediate postoperative pain relief (Barrow Neurological Institute [BNI] pain score of I or II) rate was 100%. The medium- to long-term pain relief rate was 91.7%. Three patients experienced recurrence. Facial numbness was the primary postoperative complication. Four patients with a score of III on the BNI numbness scale immediately after surgery had marked improvement at 6 months. No serious complications occurred. Conclusion Internal neurolysis is a safe and effective treatment for trigeminal neuralgia without vascular compression or clear responsible vessels.

Trigeminal neuralgia (TGN) is a very peculiar disease, mostly characterized by unilateral paroxysmal facial pain, often described by patient as ‘one of the worst pain in my life’. This condition is also known as ‘Tic Douloureus’. The annual incidence of TN is about 4.7/100000 population, male and female are equally affected. The diagnosis is usually made by history, clinical fi ndings and cranial imaging is required to rule out compressing vascular loop, organic lesions and Multiple Sclerosis (MS) at Trigeminal nerve (TN). Treatment of TGN ranged from medical to surgical intervention. Between September 2007 and April 2015, 20 patients underwent micro vascular decompression (MVD) of TN for TGN who were refractory to medical treatment at department of Neurosurgery, Bir Hospital. All decompressions were performed using operating microscope. Follow up period ranged from 22 months to 8 years.There were 9 males and 11 females and age ranged from 30-70 years. The neuralgic pain was localized on right side in 13 patients and left on 7 patients. Pain distribution was on V3 (mandibular branch) dermatome in 11, V2( Maxillary branch ) in 4, V2-3 in 2 and V1- 2-3 in 3 patients respectively. On intraoperative fi ndings TN was compressed by superior cerebellar artery ( SCA ) in 8, tumors in 4, unidentifi ed vessels in 3, veins in 2, anterior inferior cerebellar artery ( AICA ) in 1 and no cause was found in 2 patients. 7 patients suffered postoperative complications which included hyposthesia in 3, pseudomeningocele in 3 and meningitis in 1. There was no mortality in this series. 20 patients felt pain relief immediately after procedure and 1 patients came after 3 years with recurrent pain requiring second surgery. In conclusion, MVD for TGN in younger patients who are refractory to medical treatment is one of the best treatment options which is safe and long term pain relief is achieved in majority of cases.Nepal Journal of Neuroscience, Vol. 14, No. 2,  2017 Page:11-15

Abstract INTRODUCTION Trigeminal neuralgia (TGN) is a facial pain disorder that is paroxysmal, stabbing, and produces a shooting pain that affects the face due to the compression of the trigeminal nerve. Literature has suggested that the use of an endoscope for microvascular decompression (eMVD), as opposed to a microscope alone, is more likely to identify the source of neurovascular compression and ensure that the nerve is adequately decompressed. However, the recurrence of TGN pain continues to be an issue for patients. This project will assess the long-term success of eMVD using the reduction in Barrow Pain Scale score and recurrence rate at 1 yr. METHODS This retrospective chart review aims at exploring the efficacy of eMVD for TGN by studying rates of recurrence in a cohort of 300 patients and comparing them to the literature using descriptive statistics. This is the largest study to date evaluating postoperative recurrence for eMVD for TGN. RESULTS In this cohort, on average, patients reduced their pain scale by 2.99 units on the Barrow Pain Scale. Additionally, 95.5% of patients experienced an immediate pain relief after eMVD surgery, while only 4.3% had no improvement in TGN pain after the procedure. In this eMVD patient cohort, 22% of patients had partial recurrence of TGN pain. CONCLUSION The endoscope seems to provide long-term success for eliminating TGN pain and is at least as successful as traditional MVD. Over 95% of patients with follow-up data experienced an immediate pain relief, indicating that the efficacy of this procedure is excellent. Recurrence rates of TGN pain seem to be comparable to the existing literature on traditional MVD approaches. This cohort had a partial recurrence rate of 22%, while previous MVD studies have shown significant recurrence rates between 3% and 32%. This indicates that significant recurrence rates of TGN need to be further investigated.

We have treated 93 ruptured aneurysms with Guglielmi Detachable Coils (GDC) in acute period. Seventy-three patients (78%) were independent on discharge. Among the patient of Hunt and Hess Grade I, II and III, 59 patients (88%) were independent. Acute re-rupture occurred in two elderly patients with insufficient embolization and two patients experienced re-rupture in the follow up period. Symptomatic vasospasm was reported in 17.6% of patients. The permanent morbidity rate is 4.4% and one patient died (1.5%). Although the long-term results remain to be determined, embolization with GDC is a safe and promising treatment for acutely ruptured aneurysms.

Meta Analyses

Background: The success of repeat surgery for recurrent trigeminal neuralgia (TN)—with microvascular decompression (MVD), percutaneous rhizotomy (PR), or stereotactic radiosurgery (SRS)—is not well-studied. We performed a systematic review and meta-analysis of the literature on repeat surgery recurrent TN, focusing on the durability of pain relief and relative efficacy of MVD, PR, and SRS. Methods: A PRISMA systematic review of Medline/Embase/Pubmed identified studies of adults with unilateral idiopathic TN undergoing repeat surgery. The primary outcome of complete pain relief (CPR) at last follow-up was analyzed with a multivariate mixed-effects meta-analysis of proportions. Results: Seventy-eight studies met criteria; 61 were included in meta-analyses, containing 29/14/25 cohorts with 900/684/1353 patients undergoing MVD/PR/SRS respectively (mean age 64.7 years, 41% males). Initial CPR was 69% (74%/85%/52%). CPR at mean 39.7 month follow-up (38.3/38.8/41.0) was 48% (59%/60%/34%). Initial CPR for both MVD (CPR: 0.78 [0.70-0.85]) and PR (CPR: 0.93 [0.83-0.98]) was superior to SRS (CPR: 0.48 [0.35-0.61]). At follow-up, MVD (0.45 [0.32-0.58]) and PR (0.45 [0.30-0.60]) trended towards superior CPR versus SRS (0.25 [0.15-0.37]). Conclusions: Half of recurrent TN patients achieve good pain control 3 years after repeat surgery. MVD/PR showed superior initial pain relief and likely better long-term relief. These findings can inform surgical decision-making in this challenging population.

End Point

Aim: Prognostic factors detection and analysis of long-term results of microvascular decompression for trigeminal neuralgia. Materials and methods.  161 cases of trigeminal neuralgia (TN) treatment by MVD technique without preliminary invasive interventions within 10 years were analyzed. Two blocks of information were designed which included objective case data (8 factors) and patient satisfaction survey (5 questions). Follow-up minimal cut-off was 1 year (median 5.8 years). The primary end point is the proportion of pain free patients and BNI (Barrow Neurological Institute) score at last follow-up. The secondary end point is the assessment of possible risk factors of  treatment failure: symptoms duration, decompression type, affected nerve branches, neurovascular conflict visible on MRI, different indications for surgery. Logit-regression analysis was carried out. Significance level was set at p<0,01. Results. Among the studied factors as predictors for pain recurrence all but one failed to reach significance threshold. Conflict on MRI (p=0,231), involved nerve branches (p=0,340), indications for surgery (p=0,659), number of involved vessels (p=0,834), achieved decompression type (p=0,157), venous compression (p=0,143), gender (p=0,150), affected side (p=0,934) did not reach the significance level. For symptoms duration p=0,0012. Conclusions. As a result of multifactorial analysis   of study results, the only significant prognostic factor for treatment failure (pain recurrence or worsening of obtained result) was symptoms duration at the time of surgery.
