Trigeminal neuralgia

Discussion/General Information

Trigeminal neuralgia is a neurological condition affecting the sensory division of the fifth cranial (trigeminal) nerve. It is characterized by recurrent episodes of severe pain, which is confined to the distribution of one or more of the trigeminal nerve's three branches: the ophthalmic (V1), maxillary (V2), and mandibular (V3) divisions. The sensory root of the trigeminal nerve supplies the face, teeth, mouth, and nasal cavity. In trigeminal neuralgia, sudden and excruciating unilateral (one-sided) facial pain arises, following stimulation of specific trigger zones by movement or touch.

The mechanism of trigeminal neuralgia pain remains unknown. One theory suggests that peripheral injury or disease of the trigeminal nerve increases afferent firing in the nerve, perhaps by ephaptic transmission between afferent unmyelinated axons and partially damaged myelinated axons. Failure of central inhibitory mechanisms may also be involved. Blood vessel and nerve cross compression, aneurysms, chronic meningeal inflammation, tumors, or other lesions may irritate trigeminal nerve roots along the pons. In some cases, no vascular or other lesion is identified, thus rendering the etiology unknown.

Medical Therapy

Conservative, pharmacological management is considered first-line treatment for trigeminal neuralgia (Bendtsen, 2019; Rana, 2023). Despite the considerable number of drugs used, the medical management of trigeminal neuralgia is often challenging. Carbamazepine (gold standard) and oxcarbazepine are primarily regarded as the top choices for managing pain. Nevertheless, the significant side effects of these two medications might negatively impact an individual’s motivation to proceed with pharmacologic therapy. Doses are typically started low and increased gradually as tolerated over the course of several weeks (daily recommended doses, 0.2–1.2 g and 0.6–1.8 g, respectively). Sleepiness, vertigo, nausea, double vision, and reduced neuromuscular control, as well as cognition issues, are the most frequently reported side effects of these drugs. Rare but serious hypersensitivity reactions to both first-line medications include Stevens-Johnson syndrome and toxic epidermal necrolysis (Rana, 2023). Consensus expert opinion (European Academy of Neurology) suggests that carbamazepine may have a 50% failure rate for long-term (5–10 years) pain control and though often less effective, oxcarbazepine is typically better tolerated (Bendtsen, 2019).

Radiofrequency Therapies

In the majority of cases, trigeminal neuralgia can be medically managed using long-term drug therapy. Based on the American Academy of Neurology (AAN) Practice Parameters, for individuals unwilling, unable, or refractory to drug therapy, there are several options in addition to RF neurolysis. These options include, but are not limited to: surgery, gamma knife radiosurgery, or microvascular decompression (Level C recommendation). The AAN further states:

There is little evidence to guide the clinician on the treatment of patients with TN [trigeminal neuralgia] who fail first-line [drug] therapy…Referral for a surgical consultation seems reasonable in patients with TN refractory to medical therapy. Some TN experts believe patients with TN failing to respond to first-line therapy are unlikely to respond to alternative medications and suggest early surgical referral (AAN, 2008; reaffirmed 2021).

The optimal timing of surgical referral remains a crucial question. How many different drugs should be tried before referring a patient for surgery? What is the likelihood that a patient with TN failing OXC [Oxcarbazepine] or CBZ [Carbamazepine] will respond to alternative drugs? These are questions that could be answered by a large prospective cohort survey of patients with TN treated in a standardized, stepwise fashion.

RF neurolysis involves the use of heat produced by radio waves, which is percutaneously introduced via electrode placement adjacent to the trigeminal nerve using fluoroscopic guidance. This creates a lesion within the trigeminal nerve, which interrupts the painful sensory nerve impulses. RF neurolysis has the potential risk of neuritis. In addition, histological studies have revealed indiscriminate destruction of both small and large fibers following RF neurolysis. For this reason, PRF has been considered as a non-destructive alternative to standard RF neurolysis in that it applies RF energy with a pulsed time cycle that delivers short bursts of RF current instead of a continuous RF flow. By pulsing the electrical current, the needle remains relatively cool (up to 42 degrees Celsius compared to temperatures of 60-69 degrees Celsius with continuous RF) so that the tissue cools slightly between each burst, reducing the risk of destroying nearby tissue and preventing any long-term damage to the nerve. It is postulated that this disrupts the transmission of impulses across small unmyelinated fibers without destroying them, while larger fibers remain protected by the myelin sheath.

Radiofrequency Neurolysis

A number of clinical studies evaluating the clinical utility of RF neurolysis for trigeminal neuralgia have been published in the peer-reviewed medical literature. These studies include four prospective, uncontrolled clinical trials (Mathews, 2000; Scrivani, 1999; Taha, 1995; Zakrzewska, 1999) and one retrospective, uncontrolled chart review (Kanpolat, 2001). Three additional retrospective comparative studies examined the efficacy of RF neurolysis, as compared with other established treatment modalities, including microvascular decompression (MVD), balloon microcompression (BMC), glycerol rhizotomy (GR), partial trigeminal rhizotomy (PTR), neurectomy and alcohol block (Oturai, 1996; Taha, 1996). A literature search did not identify any placebo-controlled studies. The major outcome measures were largely subjective and included pain relief, recurrence rates and side effects (such as facial numbness/degree of sensory loss), trigeminal motor dysfunction, and nerve deficits.

In these studies, 83-99% of participants treated with RF neurolysis experienced initial complete pain relief. Taha and Tew (1996) reported initial success rates of 98% for RF ablation and MVD with recurrence rates of 20% and 15% for RF neurolysis and MVD, respectively. RF neurolysis resulted in similar initial success rates as observed with BMC, GR and PTR. Pain recurrence rates were highest for GR (54%), followed by RF neurolysis (20% to 23%), BMC (21%), PTR (18%), and MVD (15%). Initial success rates and recurrence rates were lower for neurectomy and alcohol block (42%) compared to RF neurolysis, with comparable incidence of complications (Oturai, 1996). Repeat procedures increased long-term efficacy in three studies (Kanpolat, 2001; Mathews, 2000; Scrivani, 1999). Long-term safety data from prospective uncontrolled and retrospective clinical studies are available for a time frame of 6 months to 20 years. Although these studies have methodological limitations and variations in study design, the data suggest that RF neurolysis is a relatively effective treatment option for those with trigeminal neuralgia with few serious, irreversible complications.

Zakrzewska and colleagues (2011) reviewed the literature for RF as compared with MVD treatments. Ablative procedures result in sensory loss, and MVD carries a 0.2-0.4% risk of mortality with a 2-4% chance of ipsilateral hearing loss. However, both procedures provided pain relief: 50% in RF and 70% in MVD over 14 years.

Another meta-analysis of 14 studies compared the clinical utility of three percutaneous treatments for trigeminal neuralgia; RF, glycerol rhizotomy (GR) and balloon compression (BC); each treatment aims to injure the trigeminal nerve by targeted injury to the nerve fibers. The comparisons of RF versus GR comprised 2518 individuals and showed that RF was associated with a statistically significant higher odds of immediate pain relief (odds ratio [OR]=2.65; 95% confidence interval [CI], 1.29 to 5.44) when compared to GR. The RF group also had a statistically significant higher risk of anesthesia in the trigeminal distribution (OR=4.73; 95% CI, 2.25 to 9.96) and a lower risk for herpes eruption (OR=0.30; 95% CI, 0.17 to 0.56). Compared to BC, RF did not show significant differences between the two groups (n=3183). Authors conclude that RF is as good as, or better than, other widely used percutaneous treatments for trigeminal neuralgia (Texakalidis, 2019).

In 2024, Huang and colleagues published results of a retrospective cohort study conducted in a single center in China. A total of 84 individuals who were diagnosed with trigeminal neuralgia and received RF ablation for refractory trigeminal neuralgia were included in the analysis. Initial treatment success was achieved in 76/84 (90%) of study participants. During the follow-up period, successful control of trigeminal neuralgia symptoms was sustained in 64/76 (84%), 40/73 (55%), 20/67 (30%), 17/65 (26%), 12/61 (20%), and 8/58 (14%) of study participants at 1, 2, 3, 4, 5, and 6 years, after the first procedure, respectively. RF ablations resulted in better long-term outcomes in participants who typically experienced paroxysmal pain (24 months vs. 11 months, p=0.033). The study authors concluded that, “Radiofrequency ablation of the peripheral branches of the trigeminal nerve might be a safe and effective method in the treatment of refractory trigeminal neuralgia.” The duration of effect was robust the first year following intervention and subsequently diminished each year thereafter, though the high rate of attrition impedes confidence in the study’s annual estimates past year 1.

Pulsed Radiofrequency Therapy

Erdine and colleagues (2007) reported the results of a trial of 40 participants with trigeminal neuralgia who were randomized to receive either PRF or conventional RF. Measurements of pain improved in those treated with conventional RF, but in only 2 of 20 who received PRF. The authors concluded that PRF therapy was not an effective treatment for trigeminal neuralgia.

Li and colleagues (2012) reported a prospective randomized controlled study (RCT) of 60 participants with trigeminal neuralgia to compare treatment with continuous RF (CRF) or PRF combined with CRF to the Gasserian ganglion (GG). Participants were randomized into three groups receiving either 75°C CRF for 120s (seconds) to 180s (SCRF group), 75°C CRF for 240s to 300s (LCRF group), or 42°C PRF for 10 minutes followed by 75°C CRF for 120s to 180s (PCRF group). Participants were assessed for pain intensity, quality of life (QOL), and intensity of facial dysesthesia at baseline, at 7 days, and at 3, 6, and 12 months after the procedure. The efficacy in pain relief was most significant 7 days after treatment, and there were no significant differences between groups. After 12 months, greater than 70% of those in each group had complete pain relief, and the QOL in all three groups had increased significantly compared to baseline. The authors concluded that PRF combined with CRF can achieve comparable pain relief to those who receive CRF alone; however, shorter exposure of CRF could result in less destruction of the target tissue. Although the outcomes of this study are promising, larger studies with longer follow-up are needed to validate the clinical efficacy of treatment using RF combined with PRF.

Chua and colleagues (2012) conducted a retrospective review of 36 individuals treated for trigeminal neuralgia with PRF. The researchers conducted telephonic follow-up interviews for 34 participants. From the retrospective review of the documented clinical results of all 34 individuals, the percentages of those who showed excellent pain relief (greater than or equal to 80% pain relief) at 2, 6, and 12 months were 73.5% (25/34), 61.8% (21/34), and 55.9% (19/34), respectively; those with satisfactory pain relief (50-80% pain relief) at 2, 6, and 12 months were 14.7% (5/34), 17.6% (6/34), and 17.6% (6/34), respectively; and those showing less than satisfactory pain relief (less than 50% pain relief) at 2, 6, and 12 months were 11.8% (4/34), 20.6% (7/34), and 23.5% (8/34), respectively. No complications were reported, and no individuals required hospitalization. The authors acknowledged that more research is required to qualify PRF for trigeminal neuralgia as an accepted treatment modality.

The use of pulsed radiofrequency (PRF) for the treatment of trigeminal neuralgia, either as a sole treatment or combined with RF, is controversial. Studies supporting the benefit of PRF for trigeminal neuralgia consist of small studies, case studies, or retrospective reviews (Liao, 2017; Thapa, 2015; Zhao, 2015). While some studies have reported potential benefit with PRF therapy under specific circumstances (Yao, 2016), further large, randomized studies are needed to evaluate efficacy in the clinical setting.

Sridharan and Sivaramakrishnan (2017) performed a meta-analysis to compare the efficacy of various interventions for refractory trigeminal neuralgia. For radiofrequency-related interventions, the authors included four RCTs (n=196). The authors found that continuous radiofrequency (alone or in combination with pulsed radiofrequency) was more effective than pulsed radiofrequency alone, including high voltage pulsed radiofrequency. However, the authors noted that the quality of evidence was low, and high-quality trials are needed to generalize the findings.

In 2019, Wu and colleagues published a systematic review and meta-analysis on the efficacy and safety of RF ablation for the treatment of trigeminal neuralgia. The authors included 34 studies (n=3558) on CRF, PRF and combined CRF and pulsed radiofrequency (CCPRF). A total of 79.4% of the studies were considered low quality. They concluded that CCPRF has the potential to have clinical utility, but further RCTs are needed before any recommendations can be made.

In 2023, Mansano and colleagues conducted an RCT which enrolled 30 participants with classical trigeminal neuralgia who had failed to respond to drug treatment. Participants were randomized 1:1 into one of two groups, a thermal RF or a control group. Following sensory and motor stimulation, the group received RF at 75°C for 60 seconds. The primary outcomes were the Numerical Rating Scale (NRS), the 36-Item Short-Form Health Survey questionnaire, and anticonvulsant dose. After 1 month, the mean NRS score decreased from 9.2 to 0.7 in the RF group and from 8.9 to 5.8 in the sham group, this reduction was measurable within 1 day of the procedure and remained significant throughout the first month. After 1 month, participants were permitted to change groups, 1 participant from the RF group and 12 from the control group crossed over, after which time the pain reduction was similar between the groups. The SF-36 scores demonstrated improvement in the first 30 days following the procedure, these differences diminished for the remaining 11 months of the study’s follow-up period after cross-over was permitted. Similarly, there was a significant reduction in the use of anticonvulsants within the first 30 days following RF, whereas the remaining 11 months showed no statistical difference. Authors conclude that, “these results support using radiofrequency nerve ablation as at treatment for refractory trigeminal neuralgia.”

In 2023, Jia and colleagues published results from a double-blind RCT conducted in Beijing, China which enrolled 134 individuals diagnosed with primary trigeminal neuralgia who had responded poorly to drug therapy or were unable to tolerate drug side effects. Participants were randomized to receive high voltage PRF (360s of 42°C PRF treatment at the highest output voltage that participants could tolerate; n=67) or a nerve block (n=67). At 1 year post procedure, the proportion of study participants with a positive response (proportion of study arm with ‘excellent’ or good’ pain relief according to the Barrow Neurological Institute [BNI] pain intensity score) was significantly higher in the PRF arm compared to the nerve block arm in the intention-to-treat population (73.1% vs. 32.8%, p<0.001). The incidence of adverse events was similar between groups. While the results are promising, confirmatory trials including more detailed procedural descriptions are warranted to facilitate replication of this novel form of PRF as a treatment for trigeminal neuralgia (Jia, 2018). As the authors state, “optimal parameters of PRF such as treatment duration, output voltage or temperature should be further investigated.”

Systematic reviews and meta-analyses continue to support the efficacy of RF ablation as a treatment for trigeminal neuralgia with mixed conclusions regarding the efficacy of PRF therapy (Garcia-Isidoro; 2021; Orhurhu, 2020; Texakalidis, 2021; Zhang, 2022).
