Trigeminal neuralgia is a recurrent episode of facial pain, that may be associated with other conditions such as multiple sclerosis, neoplasms, and nerve compromises or may occur due to an unknown cause. The available treatments are pharmacotherapy or surgery; however, both are susceptible to develop side effects. Photobiomodulation could be a promising alternative therapy for trigeminal neuralgia. A systematic review of literature was carried out using the PRISMA protocol, in the PubMed/MEDLINE, Embase, and Web of Science databases. Risk of bias by ROB 2.0 protocol was performed in included studies. Initially, 20 identified articles were collected varying between the years of 1983-2018, from which 6 were included. A total of 193 patients were evaluated; photobiomodulation was compared to conventional therapies, TENS, and therapy combinations with pharmacotherapy. The overall risk of bias was low, with some concerns in the randomization and double-blinding process; moreover, there are few reports in the literature. Photobiomodulation appears to be as effective as conventional therapies, being a coadjutant therapeutic opportunity for the treatment of trigeminal neuralgia.

The correlation study between posterior fossa crowding and classical trigeminal neuralgia.

Acta Neurochir (Wien)

January 2025

Department of Neurosurgery, Hebei General Hospital, 348# Heping Road, Shijiazhuang City, 050000, Hebei Province, China.

Objective: To explore the correlation between posterior fossa crowding and the occurrence of classical trigeminal neuralgia (TN).

Methods: A total of 60 patients diagnosed with classical TN and 60 age- and sex-matched healthy volunteers were included as a control group for a case-control study. All subjects underwent high-resolution 3D magnetic resonance imaging (MRI) examinations (including 3D-FIESTA and 3D-TOF MRA sequences).

Background: Bilateral trigeminal neuralgia secondary to multiple sclerosis is an extremely rare condition. When Gasserian ganglion block is performed, it is necessary to achieve reliable long-term analgesic effects while avoiding treatment-related complications.

Case Presentation: A 49-year-old male with multiple sclerosis exhibited persistent dull pain and paroxysmal electric shock-like pain in his bilateral maxillary molars and mandible.

Tic douloureux, also known as trigeminal neuralgia, is distinguished by recurrent episodes of severe, lancinating pain that affects one or more branches of the trigeminal nerve, representing a prevalent pain syndrome. This condition has an annual incidence rate of 27 per 100,000 individuals. Nevertheless, direct compression caused by vertebrobasilar dolichoectasia (VBD) represents a considerably less frequent etiology of trigeminal neuralgia, with an estimated overall incidence of about 1%.
