Trigeminal neuralgia (TN), also known as tic douloureux, is a neuropathic pain syndrome characterized by paroxysmal, triggered, trigeminally distributed pain. It affects more women than men (3:1 ratio), and is more common in the elderly. The anti-epileptic drug carbamazepine (Tegretol) is the drug of choice for the management of TN. Tegretol, at a dose of 600 to 1,200 mg per day, has been demonstrated to inhibit or shorten the duration of attacks. Phenytoin (Dilantin), is also effective in treating TN, but less so than carbamazepine. For patients who can not tolerate carbamazepine because of its adverse side effects (poor liver function, confusion, ataxia, drowsiness, and allergic responses), baclofen and other anti-convulsant drugs such as clonazepam (Klonopin) may be useful. If pharmacotherapy fails, surgical intervention may be necessary.
Surgical treatment can be divided into 2 categories: (i) percutaneous, and (ii) open. The former approaches include radiofrequency rhizolysis, glycerol injection, and balloon compression techniques. The principal open approach is microvascular decompression, which entails posterior fossa craniotomy and has a small incidence of serious neurological morbidity. In general, elderly or medically debilitated patients, patients with multiple sclerosis, or individuals who have failed to attain pain relief from the open approach are encouraged to use the percutaneous approaches, while the open approach is recommended for younger and healthier subjects.
The gamma knife, one type of stereotactic radiosurgery, is also used as a means of treating patients with TN. It was developed in the 1950's by Larsson and Leksell, and is primarily used as a non-invasive alternative treatment for certain types of brain lesions such as intra-cranial arteriovenous malformations and brain tumors. When the gamma knife is used to treat TN, the beams are focused on the root of the trigeminal nerve. The stereotactic coordinates of the target site are often determined by computed tomography and/or magnetic resonance imaging. Patients undergoing gamma knife radiosurgery are usually given local anesthesia with a mild sedative.
Pulsed radiofrequency (PRF) treatment entails the application of short bursts of RF energy to nervous tissue. It is a minimally destructive procedure that may serve as an alternative to traditional RF heat lesion. In a review on PRF treatment, Gallagher (2006) stated that "we should cautiously prescribe this promising intervention following clinical algorithms that are based upon the best clinical evidence available. However, it is critically important to avoid the mistake of creating a "carte blanche" environment for those practitioners who would abuse the privilege and opportunity presented by this new technology, besmirching our credibility and ultimately impeding the opportunity to use this treatment to the benefit of the public. Ultimately, evidence, not reimbursement, should determine whether PRF finds a place in our clinical toolbox".
Cahana et al (2006) stated that PRF, a non- or minimally-neurodestructive technique, has been used as alternative to radiofrequency heat lesions. Clinical advantages and mechanisms of PRF remain unclear. These investigators reviewed current clinical and laboratory data on PRF. The final analysis yielded 58 reports on the clinical use of PRF in different applications: 33 full publications and 25 abstracts. They also retrieved 6 basic science reports, 5 full publications, and 1 abstract. The authors concluded that the accumulation of these data showed that the use of PRF generates an increasing interest of pain physicians for the management of a variety of pain syndromes. Although the mechanism of action has not been completely elucidated, laboratory reports suggested a genuine neurobiological phenomenon altering the pain signaling, which some researchers have described as neuromodulatory. No side effects related to PRF were reported to date. They stated that further research in the clinical and biological effects of this technique is justified.
In the only controlled clinical trial of PRF for TN published to date, Erdine et al (2007) concluded that PRF is not an effective treatment for TN. Erdine et al (2007) reported on a prospective, randomized, double-blinded study to compare PRF to conventional radiofrequency (CRF) in the treatment of idiopathic TN. A total of 40 patients with idiopathic TN were randomly assigned to PRF or CRF. Visual Analog Scale (VAS) scores decreased significantly (p < 0.001) and Patient Satisfaction Scale (PSS) scores improved significantly (p < 0.001) after the procedure in subjects assigned to CRF. The VAS score decreased in only 2 of 20 patients from the PRF group and pain recurred 3 months after the procedure. The investigators reported that, at the end of 3 months, they performed CRF in patients assigned to PRF, because all patients in this group still had intractable pain.
Cheshire (2007) staetd that many treatments have been developed for TN. Anti-epileptic drugs are superior to traditional analgesics with carbamazepine being the drug of first choice. Additional drugs for which there is evidence of efficacy include oxcarbazepine, baclofen, gabapentin, lamotrigine and phenytoin. However, many patients eventually experience tachyphylaxis or may not tolerate effective doses. Surgical interventions include microvascular decompression; balloon compression; RF thermocoagulation or glycerol rhizotomies; and subcutaneous alcohol branch blockade. Stereotactic gamma knife radiosurgery is a further option. Motor cortex stimulation and transcranial magnetic stimulation, although having shown initial promise for trigeminal neuropathic pain, seem to be ineffective for classical TN.
The Quality Standards Subcommittee of the American Academy of Neurology and the European Federation of Neurological Societies' practice parameter on the diagnostic evaluation and treatment of TN (Gronseth et al, 2008) stated that for patients with TN refractory to medical therapy, Gasserian ganglion percutaneous techniques, gamma knife, and microvascular decompression may be considered.
Adler et al (2009) stated that although stereotactic radiosurgery is an established procedure for treating TN, the likelihood of a prompt and durable complete response is not assured. Moreover, the incidence of facial numbness remains a challenge. To address these limitations, a new, more anatomic radiosurgical procedure was developed that uses the CyberKnife (Accuray, Inc., Sunnyvale, CA) to lesion an elongated segment of the retro-Gasserian cisternal portion of the trigeminal sensory root. Because the initial experience with this approach resulted in an unacceptably high incidence of facial numbness, a gradual dose and volume de-escalation was performed over several years. In this single-institution prospective study, these researchers assessed clinical outcomes in a group of TN patients who underwent lesioning with seemingly optimized non-isocentric radiosurgical parameters. A total of 46 patients with intractable idiopathic TN were treated between January 2005 and June 2007. Eligible patients were either poor surgical candidates or had failed previous microvascular decompression or destructive procedures. During a single radiosurgical session, a 6-mm segment of the affected nerve was treated with a mean marginal prescription dose of 58.3 Gy and a mean maximal dose of 73.5 Gy. Monthly neurosurgical follow-up was performed until the patient became pain-free. Longer-term follow-up was performed both in the clinic and over the telephone. Outcomes were graded as excellent (pain-free and off medication), good (greater than 90 % improvement while still on medication), fair (50 to 90 % improvement), or poor (no change or worse). Facial numbness was assessed using the Barrow Neurological Institute Facial Numbness Scale score. Symptoms disappeared completely in 39 patients (85 %) after a mean latency of 5.2 weeks. In most of these patients, pain relief began within the first week. Trigeminal neuralgia recurred in a single patient after a pain-free interval of 7 months; all symptoms abated after a second radiosurgical procedure. Four additional patients underwent a repeat rhizotomy after failing to respond adequately to the first operation. After a mean follow-up period of 14.7 months, patient-reported outcomes were excellent in 33 patients (72 %), good in 11 patients (24 %), and poor/no improvement in 2 patients (4 %). Significant ipsilateral facial numbness (Grade III on the Barrow Neurological Institute Scale) was reported in 7 patients (15 %). The authors concluded that optimized non-isocentric CyberKnife parameters for TN treatment resulted in high rates of pain relief and a more acceptable incidence of facial numbness than reported previously. Moreover, they stated that longer follow-up periods will be needed to establish whether or not the durability of symptom relief after lesioning an elongated segment of the trigeminal root is superior to isocentric radiosurgical rhizotomy.
Fariselli et al (2009) reported the safety and effectiveness and safety of CyberKnife robotic radiosurgery as a first-line treatment against pharmacologically refractory TN. These investigators treated 33 patients with the frameless CyberKnife system as a monotherapy. The retro-Gasserian portion of the trigeminal nerve (a length of 4 mm, 2 to 3 mm anterior to the root entry zone) was targeted. Doses of 55 to 75 Gy were prescribed to the 100 % isodose line, according to a dose escalation protocol. Patients were evaluated for the level of pain control, time to pain relief, hypesthesia, and time to pain recurrence. The median age was 74 years. All but 2 patients (94 %) achieved a successful treatment outcome. The follow-up period was 9 to 37 months (mean of 23 months). The Barrow Neurological Institute Pain Intensity Scale (BPS) score before radiosurgery was III in 2 patients (6 %), IV in 8 patients (24 %), and V in 23 patients (70 %). The time to pain relief was 1 to 180 days (median of 30 days). No facial numbness was observed. Only 1 patient developed a transitory dysesthesia of the tongue. After treatment, the BPS score was I, II, or III in 31 patients (97 %). Pain recurred in 33 % (11 patients) at a mean of 9 months (range of 1 to 43 months). Three patients with recurrences had low pain control by medication (BPS score, IV), and 1 patient (BPS score, V) needed a RF lesioning (BPS score, I at 12 months). The authors concluded that CyberKnife radiosurgery for TN allows pain relief at safe doses and is suggested for pharmacologically refractory TN. It should be noted that the rate of pain recurrence is rather high in this study (33 %).
Kouzounias et al (2010) compared percutaneous balloon compression (PBC) and percutaneous retrogasserian glycerol rhizotomy (PRGR) for the treatment of TN in terms of effectiveness, complications, and technical aspects. A total of 66 consecutive PBC procedures were performed in 45 patients between January 2004 and December 2008, and 120 PRGR attempts were performed in 101 patients between January 2006 and December 2008. The PRGR procedures were not completed due to technical reasons in 19 cases. Five patients in the PBC group and 9 patients in the PRGR group were lost to follow-up and were excluded from the study. The medical records as well as the intra-operative fluoroscopic images from the remaining cases were retrospectively examined, and the follow-up was completed with telephone contact, when necessary. The 2 groups were compared in terms of initial effect, duration of effect, and rates of complications as well as severity and type of complications. The rates for immediate pain relief were 87 % for patients treated with glycerol injection and 85 % for patients treated with balloon compression. The Kaplan-Meier plots for the 2 treatment modalities were similar. The 50 % recurrence time was 21 months for the balloon procedure and 16 months for the glycerol procedure. When the groups were broken down by the "previous operations" criterion, the 50 % recurrence time was 24 months for the Glycerol First Procedure Group, 6 months for the Balloon First Procedure Group, 8 months for the Glycerol Previous Procedures Group, and 21 months for the Balloon Previous Procedures Group. The rates of complications (excluding numbness) were 11 % for PRGR and 23 % for PBC, and this difference was statistically significant (chi-square test, p = 0.04). The authors concluded that both PRGR and PBC are effective techniques for the treatment of TN, with PRGR presenting some advantages in terms of milder and fewer complications and allowing lighter anesthesia without compromise of analgesia. For these reasons the authors consider PRGR as the first option for the treatment of TN in patients who are not suitable candidates or are not willing to undergo microvascular decompression, while PBC is reserved for patients in whom the effect of PRGR has proven to be short or difficult to repeat due to cisternal fibrosis.
A Cochrane review on “Neurosurgical interventions for the treatment of classical trigeminal neuralgia” (Zakrzewska and Akram, 2011) noted that surgical treatments for refractory trigeminal neuralgia are divided into 2 main categories: (i) ablative (destructive) and (ii) non-ablative. These treatments can be done at 3 different sites: (i) peripherally, (ii) at the Gasserian ganglion level, and (iii) within the posterior fossa of the skull. The authors concluded that “There is very low quality evidence for the effectiveness of most neurosurgical procedures for trigeminal neuralgia because of the poor quality of the trials. All procedures produced variable pain relief, but many resulted in sensory side effects …. Well-designed studies are urgently needed”.
An UpToDate review on "Trigeminal neuralgia" (Bajwa et al, 2013) states that “Peripheral neurectomy can be performed on the branches of the trigeminal nerve, which are the supraorbital, infraorbital, alveolar, and lingual nerves. Neurectomy is accomplished by incision, alcohol injection, radiofrequency lesioning, or cryotherapy. Cryotherapy involves freezing of the nerve using special probes, in theory to selectively destroy the pain fibers. The AAN/EFNS practice parameter noted that the evidence regarding peripheral techniques for the treatment of TN is either negative or inconclusive”.
Collet et al (2013) stated that the etiology of TN remains unclear and several theories have been proposed. Many medical and surgical methods have been applied with only partial effectiveness and several side effects. New hypotheses and therapeutic methods are urgently needed. Using evidence presented in a literature review and in the authors’ case report, these researchers hypothesized that pain resulting from TN can be caused by demyelinating lesions in the trigger zone.; and that these lesions can be repaired through the injection of fat containing adipose-derived stem cells.
Parmar et al (2013) stated that pharmacotherapy still remains the first line therapy for the management of TN. However, often the patients become refractory to the pharmacotherapy and need surgical interventions. There is a wide array of surgical treatment modalities available for TN. These investigators evaluated the various surgical modalities by employing a comparative analysis with respect to patient selection, success rate, complications and cost-effectiveness. For the evaluation, a critical review of literature was done with pre-defined search terms to obtain the details of individual procedures, which were then compared, under similar parameters. The results suggested that microvascular decompression seem to be the most effective treatment in terms of patient satisfaction and long term cost-effectiveness. However, if patient factors do not permit, then the peripheral procedures may be employed as a substitute, though they have higher recurrence rate and complications and have relatively lower long-term cost effectiveness. The authors noted that newer modalities like stereotactic radiosurgery and botulinum toxin have promising results and further refinement in these procedures will provide additional options for the patients suffering from TN.
Hu and colleagues (2013) systematically reviewed the therapeutic safety and effectiveness of botulinum toxin type A (BTX-A) in the treatment of TN. PubMed, EMBASE, Cochrane Library Clinical Trials and Web of Science from January 1966 to March 2013 were searched with the terms of "botulinum toxin" and "trigeminal neuralgia", and references of related articles were traced. Data on the safety and effectiveness of BTX-A in this disorder were extracted and analyzed by at least 2 reviewers. Data for individual studies were reported, and pooled data were analyzed if appropriate. A total of 5 prospective studies and 1 double-blind, randomized, placebo-controlled study were identified. Response was achieved in approximately 70 to 100 % of patients, and the mean pain intensity and frequency were reduced by approximately 60 to 100 % at 4 weeks after treatment in most studies. Major adverse events were not reported. Available studies showed BTX-A may be effective in treatment of TN. However, the authors concluded that well-designed randomized, controlled, double-blinded trial is still lacking. They stated that future BTX-A treatment studies on optimal dose, duration of the therapeutic effectiveness, common adverse events, and the time and indications for repeat injection would be promising.
Fontaine et al (2014) stated that although most patients suffering from TN respond to medical or surgical treatment, non-responders remain in very severe painful condition. These researchers described for the first time a case of severe refractory classical TN treated successfully (follow-up 1 year) by chronic bilateral occipital nerve stimulation (ONS), because other classic medical and surgical options failed or could not be performed. The authors concluded that this single case suggested that ONS might be offered to TN patients who are refractory both to standard drugs and interventions, with a favorable risk/benefit ratio, although its long-term effectiveness remains unknown. This preliminary finding needs to be validated by well-designed studies.
Tamburin et al (2014) reported on 2 patients with classical TN in whom conventional drugs for TN were not tolerated. In these patients, treatment with 5 % lidocaine medicated plaster (LMP) resulted in reduction of pain intensity and the number of pain paroxysms. Lidocaine medicated plaster is known to block the sodium channels on peripheral nerves and may cause a selective and partial block of Aδ and C fibers. According to the TN ignition hypothesis, blockage of peripheral afferents by LMP may reduce pain paroxysms. The effect of LMP may outlast the pharmacokinetics of the drug by reducing pain amplification mechanisms in the central nervous system; LMP has limited or no systemic side effects. The authors concluded that LMP may be an effective and well-tolerated treatment option for TN in those patients who do not tolerate or who refuse other therapies. They stated that future randomized controlled studies should better address this issue.
Stavropoulou et al (2014) stated that intravenous lidocaine infusions are gaining acceptance in a variety of pain-management settings. These researchers stated that future clinical research should focus on identifying the effective dosage of lidocaine alone, magnesium alone, and lidocaine-magnesium combination to be used in the treatment of TN.
An UpToDate review on “Trigeminal neuralgia” (Bajwa et al, 2015) states that “Several other drugs have shown some evidence of efficacy for TN in small, generally lower-quality controlled trials …. Topical lidocaine given by intra-oral application was more effective than placebo for pain reduction in a two-week, randomized cross-over trial of 24 subjects with TN whose pain was most severe pain in the mouth. However, blinding may have been compromised because of the bitter taste or numbness perceived by some patients when treated with lidocaine …. There is only limited evidence to support treatment alternatives for patients with TN who are refractory to first-line medical therapy …. Intravenous infusion of phenytoin, fosphenytoin or lidocaine may provide analgesia while oral medications are titrated …. Nevertheless, there are no randomized controlled trials comparing monotherapy with combination therapy for TN”. Moreover, magnesium is not mentioned as a therapeutic option.
Tuleasca et al (2014) examined the safety and effectiveness of repeat Gamma Knife surgery (GKS) for recurrent TN. Using the prospective database of TN patients treated with GKS in Timone University Hospital (Marseille, France), data were analyzed for 737 patients undergoing GKS for TN Type 1 from July 1992 to November 2010. Among the 497 patients with initial pain cessation, 34.4 % (157/456 with greater than or equal to 1-year follow-up) experienced at least 1 recurrence. Thirteen patients (1.8 %) were considered for a second GKS, proposed only if the patients had good and prolonged initial pain cessation after the first GKS, with no other treatment alternative at the moment of recurrence. As for the first GKS, a single 4-mm isocenter was positioned in the cisternal portion of the trigeminal nerve at a median distance of 7.6 mm (range of 4 to 14 mm) anterior to the emergence of the nerve (retrogasserian target). A median maximum dose of 90 Gy (range of 70 to 90 Gy) was delivered. Data for 9 patients with at least 1-year follow-up were analyzed. A systematic review of literature was also performed, and results are compared with those of the Marseille study. The median time to re-treatment in the Marseille study was 72 months (range of 12 to 125 months) and in the literature it was 17 months (range of 3 to 146 months). In the Marseille study, the median follow-up period was 33.9 months (range of 12 to 96 months), and 8 of 9 patients (88.9 %) had initial pain cessation with a median of 6.5 days (range of 1 to 180 days). The actuarial rate for new hypesthesia was 33.3 % at 6 months and 50 % at 1 year, which remained stable for 7 years. The actuarial probabilities of maintaining pain relief without medication at 6 months and 1 year were 100 % and 75 %, respectively, and remained stable for 7 years. The systematic review analyzed 20 peer-reviewed studies reporting outcomes for repeat GKS for recurrent TN, with a total of 626 patients. Both the selection of the cases for re-treatment and the way of reporting outcomes vary widely among studies, with a median rate for initial pain cessation of 88 % (range of 60 % to 100 %) and for new hypesthesia of 33 % (range of 11 % to 80 %). The authors concluded that results from the Marseille study raised the question of surgical alternatives after failed GKS for TN. The rates of initial pain cessation and recurrence seem comparable to, or even better than, those of the first GKS, according to different studies, but toxicity is much higher, both in the Marseille study and in the published data. Neither the Marseille study data, nor the literature data, answered the 3 cardinal questions regarding repeat radiosurgery in recurrent TN: which patients to re-treat, which target is optimal, and which dose to use.
Tempel et al (2015) reviewed pain outcomes and complications in TN patients who required 3 radiosurgical procedures for recurrent or persistent pain. These researchers performed a retrospective review of all patients who underwent 3 Gamma Knife radiosurgery (GKRS) procedures for TN at 4 participating centers of the North American Gamma Knife Consortium from 1995 to 2012 was performed. The Barrow Neurological Institute (BNI) pain score was used to evaluate pain outcomes. A total of 17 patients were identified; 7 were males and 10 were females. The mean age at the time of last GKRS was 79.6 years (range of 51.2 to 95.6 years). The TN was Type I in 16 patients and Type II in 1 patient. No patient suffered from multiple sclerosis. Eight patients (47.1 %) reported initial complete pain relief (BNI Score I) following their third GKRS and 8 others (47.1 %) experienced at least partial relief (BNI Scores II-IIIb). The average time to initial response was 2.9 months following the third GKRS. Although 3 patients (17.6 %) developed new facial sensory dysfunction following primary GKRS and 2 patients (11.8 %) experienced new or worsening sensory disturbance following the second GKRS, no patient sustained additional sensory disturbances after the third procedure. At a mean follow-up of 22.9 months following the third GKRS, 6 patients (35.3 %) reported continued Score I complete pain relief, while 7 others (41.2 %) reported pain improvement (BNI Scores II-IIIb). Four patients (23.5 %) suffered recurrent TN following the third procedure at a mean interval of 19.1 months. The authors concluded that a third GKRS resulted in pain reduction with a low risk of additional complications in most patients with medically refractory and recurrent, intractable TN. In patients unsuitable for other microsurgical or percutaneous strategies, especially those receiving long-term oral anti-coagulation or anti-platelet agents, GKRS repeated for a third time was a satisfactory, low risk option.
