Abstract 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. Keywords Low-level laser therapy .

Introduction The trigeminal nerve is the fifth cranial nerve pair and is a voluminous nerve, with a motor and sensory component in an extensive network along the face; therefore, this nerve is highly susceptible of being affected by inflammatory and neoplastic diseases [1]. Trigeminal neuralgia (TN) is a sudden or brief and intense, sharp, superficial, or stabbing severe pain of the orofacial region through the trigeminal nerve branches, usually unilateral, as defined by the International Association for Supplementary Information The online version contains supplementary material available at https://doi.org/10.1007/s10103-02003198-6. * Ana Melissa Ccopa Ibarra [email protected] 1

the Study of Pain (IASP) [2]. The incidence of TN varies from 4.3 to 27 new cases per 100.000 people a year with a higher incidence among women [3, 4]. In most cases, TN is caused by a compression of the trigeminal nerve, which may be observed by the magnetic resonance imaging tech
