Non-surgical treatment for Trigeminal Neuralgia: Research

Ross Hauser, MD

The evidence for Trigeminal Neuralgia non-surgical treatments

In our many years of helping people with chronic pain of the head, neck, jaw, and face we have seen many people with a diagnosis of Trigeminal neuralgia. For some of these people, possibly including yourself, it was not easy getting this diagnosis as this problem can be confusing and frustrating to understand. Not only for the patient but the doctor alike.

Confusion surrounding Trigeminal Neuralgia is borne out by the definition of trigeminal neuralgia.


Trigeminal neuralgia means that there is nerve pain in the nerve distribution of the trigeminal nerve. It actually does not tell a person what is causing the condition.

When a physician and a patient believe that a nerve is getting compressed, it is easy to see why surgery would be recommended.

We are going to tackle a few brief learning points about Trigeminal Neuralgia and then we will learn about the treatment options. This article does present an optimistic and realistic opinion for non-surgical treatments.

Trigeminal neuralgia centers on what is happening to the trigeminal nerve which carries pain, feeling, and sensation from the brain to the skin of the face. In the case of trigeminal neuralgia, most medical professionals cannot find the cause for why this pain started. This is borne out by the definition of trigeminal neuralgia. Trigeminal neuralgia means that there is nerve pain in the nerve distribution of the trigeminal nerve. It actually does not tell a person what is causing the condition.

Other related causes

Trigeminal Neuralgia can also be caused by simple daily acts.

The problems you were facing and why you are seeking medical care.

Is this you?

Why are we examining the neck of a patient who comes in for a Trigeminal Neuralgia consultation?

The keyword is compression. The head and neck, as all parts of the body, live in complex relation. Something in the neck can cause problems in the jaw, face, shoulders, fingers, etc. Problems in the jaw can cause problems in the neck. Any musculoskeletal problem can cause problems of headache. Back to the keyword compression. We are looking for problems in the neck that can be influencing problems of the head and jaw. When a physician and a patient believe that a nerve is getting compressed, it is easy to see why surgery would be recommended. Unfortunately, when cervical neck instability is the cause of the neuralgia, the surgery does not help relieve the pain.

Cervical instability can also be responsible for almost all painful neuralgias of the head and face including occipital and trigeminal neuralgia,  as well as structural headaches including tension, migraines, and cluster. This is not a new concept for us, the examination of the cervical neck area is a crucial component of our comprehensive non-surgical Trigeminal Neuralgia program.

Does nerve compression equal surgery? NO.


Blood vessels compressing the nerve can be corrected without surgery or pharmacological management

Research from university and medical researchers in India published in the October-December 2017 edition of the Asian Journal of Neurosurgery reviewed current Trigeminal Neuralgia treatment. (1) Here are highlights of their research:

The surgical answer? If surgery is so successful, why then subject patients to prolonged drug use as a means to delay the need for surgery?

The Indian researchers gave an exhaustive and detailed study on how to help patients with Trigeminal Neuralgia. Like many other conditions we see, surgery is thought to be a good option, but only after years of pharmacological pain management. Why not seek something more curative?

The difficulty in diagnosis and the problems of too much treatment or inappropriate treatment was recently discussed in research by doctors in Germany at the Göttingen University Medical Center. Here they looked at oral problems.

The same study looked at the surgical treatment options:

These are very difficult procedures and invasive procedures to get only 2 out of 3 patients pain-free. One out of three continues on with their pain.

Relapse and recurrence after surgery

A September 2021 paper published in the journal Frontiers in Neurology (4) examined why a group of patients will have a recurrence of primary trigeminal neuralgia following microvascular decompression (MVD) surgery. They also note that previous research as to the actual recurrence rates and the causes of this recurrence “remain controversial.”

Summary conclusion:

What are we seeing in this image?

Trigeminal Nerve

The research on Neurectomy

A neurectomy is considered a nerve block in that it severs the nerve. In some instances, the nerve is removed completely. In March 2019, surgeons discussed neurectomy of the peripheral branches of the trigeminal nerve in the Journal of Maxillofacial and Oral Surgery. (5) Here are their findings:

“Oral and maxillofacial surgeons have traditionally employed the peripheral neurectomy in the surgical management of Trigeminal Neuralgia. . . Peripheral neurectomy in Trigeminal Neuralgia is associated with a lesser quality of pain relief in comparison with central neurosurgical procedures.  . . Oral and maxillofacial surgeons must not consider the peripheral neurectomy as the first surgical option in the management of classic Trigeminal Neuralgia.”

The research on acupuncture for Trigeminal Neuralgia

In February 2019, Chinese Medical University researchers looked into the use of acupuncture for Trigeminal Neuralgia. They noted that acupuncture is increasingly used by patients with primary trigeminal neuralgia and that research was limited as to its effectiveness. They published their findings in the journal Complementary therapies in clinical practice. (6)

In this study, the researchers examined thirty-three randomized control trial studies. Their analysis demonstrated that the effect of both manual acupuncture and electro-acupuncture for improving response rate and the recurrence rate was more significant than carbamazepine (the anticonvulsant drug frequently prescribed for Trigeminal Neuralgia.)

Manual acupuncture achieved a more significant effect on alleviating pain intensity.

However, the Chinese team concluded: acupuncture might have some positive effects on Trigeminal Neuralgia. Nevertheless, the level of all evidence was low or very low. We could not yet draw a firm conclusion on the efficacy of acupuncture for Trigeminal Neuralgia.

Another new study, however, presented interesting findings in The Journal of Nervous and Mental Disease. (7) Here Chinese University hospital researchers made these observations in regard to clinical improvement of cognitive function in patients with Trigeminal Neuralgia following acupuncture treatments.

A summary of treatments and a realistic outlook at success and non-successful treatments

In March 2019, in the European Journal of Neurology (8) research from an expanded team of European doctors lead by the  University of Copenhagen and the National Hospital for Neurology & Neurosurgery in London made these recommendations:

In the surgical aspect recommendations, two different types of surgery are offered. One the Microvascular decompression is offered when the nerve is being pressed. The Neuroablative is offered when the nerve is not being pressed. At Caring Medical we believe we can present an option away from surgery with Prolotherapy injections because we suspect many patients can be helped non-surgically with Prolotherapy treatments.


Dysfunction of the Trigeminal Nerve

Ross Hauser, MD, and Brian Hutcheson, DC discuss Trigeminal Neuralgia or dysfunction and the strange sensations through the face, throat, and ear. A summary transcript is below the video.

Case of trigeminal neuralgia helped with Prolotherapy injections

At this point, we are going to look at Prolotherapy injections as a treatment option. Prolotherapy injections are one of the simplest treatments available for trigeminal neuralgia. A simple sugar, dextrose is injected into the jaw area to strengthen the connective tissues of the jaw joint and the cervical vertebrae. 

In cases of trigeminal neuralgia, there is often an undiagnosed ligament laxity either in the neck or the temporomandibular joint (TMJ) causing referral pain patterns that create symptoms of trigeminal neuralgia.

In this case:

Previous treatments included six root canals and acupuncture yet her pain remained. A friend referred her to Caring Medical for Prolotherapy.

During the patient’s first visit she explained that her greatest pain came with eating, talking, and smiling. Often pain would shoot from her lips to her ears.

Dr. Hauser examined the patient’s TMJ and face and determined she would be a good candidate.

One month later the patient returned and reported that her face was no longer painful to the touch and she no longer had shooting pain from her lips to her ear. She had some pain with talking and eating but was hopeful that the next scheduled treatments would alleviate these problems.

Researching Prolotherapy for Trigeminal Neuralgia

In the Journal of Prolotherapy, our colleagues Eileen Conaway, DO and Brian Browning, DO describe a case history of a 63-year-old Hispanic female. (9)

The patient was referred to their office for osteopathic evaluation and treatment for chronic neck and head pain. Among other somatic complaints, her history revealed 13 years of burning pain on the left side of the forehead and scalp.

Trigeminal Neuralgia nerve diagram

Figure 1. Supraorbital nerve is a branch of the V1 ophthalmic division of the trigeminal cranial nerve (CN V). It passes through the supraorbital foramen to innervate the forehead, extending to the mid-scalp.

The pattern of her pain followed the V1 nerve path (see illustration to left). The pain began after undergoing two neurosurgical procedures to repair a cerebral aneurysm.

She reported pain even with a light touch of the affected areas of the scalp and was often unable to brush her hair due to the pain it caused. She had tried over the counter analgesics and tramadol-acetaminophen with little relief. She was initially treated with osteopathic manipulation which provided symptomatic relief for a few hours. She was hesitant to try additional medications due to their side effect profile as she also suffered from hypertension, dyslipidemia, and non-insulin-dependent diabetes.

She was treated with Neural Prolotherapy on three occasions. The first two injections were one week apart, and the third was 12 weeks later.

See the link above: Lyftogt Perineural Injection Treatment™ (also called Neurofascial Prolotherapy, as well as Neural Prolotherapy and Subcutaneous Prolotherapy) is a sometimes used side-by-side treatment with traditional dextrose based Prolotherapy. As these techniques work by different mechanisms they can diminish the pain of similar conditions, so they can be given together or separately. In Dextrose base Prolotherapy the ligament and tendon attachments are being treated, in Perineural Injection, the nerves are being treated.

After three treatments with Neural Prolotherapy, she experienced complete resolution of her V1 branch trigeminal neuralgia. After one year, the patient reports the ability to brush her hair without pain and an overall improvement in the quality of life, and her ability to perform activities of daily living.

Also detailed in the Journal of Prolotherapy is a case history described by Alan Itkin, PA-C, MS-4 in Treatment of Trigeminal Neuralgia Utilizing Neural Prolotherapy: A Case Report. (10)

Physical:
Examination showed no focal neurologic deficits. There were dysesthesias (abnormal sensation) and allodynia (abnormal and heightened sense of pain) along the maxillary and ophthalmic branches of the trigeminal nerve.

The patient was treated utilizing a neural prolotherapy technique. Approximately 15 injections were provided to the distribution of the 3 involved branches of the trigeminal nerve.

After the procedure, the patient was instructed to utilize the cotton swab to try and reproduce his symptoms. The patient was unable to reproduce any of the pain and sensitivity that was present prior to the procedure. The patient was observed in the clinic for 15 minutes and had no “tics” from trigeminal neuralgia. The patient was instructed to follow up in 1 week however the patient did not return until 6 months later.

Six month follow up:
At this visit, the patient reported that the neural prolotherapy treatment provided him with 5 months of complete resolution of his symptoms. He stated that his symptoms only returned after hitting his head when exiting his car. His complaints at this time involved severe, sharp stabbing pain in the right forehead, right eyeball, periorbital region, and right temple. He complained of pain when getting a haircut, he found that just simply touching his hair and scalp caused him severe pain.

Treatment #2:
The patient was given a second treatment of neural prolotherapy along the course of the trigeminal nerve. The same technique as the first treatment was utilized. The patient again noted an immediate, complete resolution of his pain.
