This is a narrative review based on the authors' collective experience and knowledge of the literature in addition to a PubMed search. An electronic PubMed search aimed at updating the authors' literature bank and previous reviews was performed on December 22, 2020. The search was limited to publications in English appearing between January 1, 2015 and December 20, 2020 under the search terms "TN," "facial neuralgia," and "trigeminal neuropathic pain." The resulting publication list (title and abstract) was examined to verify if patients with TN were involved. Relevant publications were retrieved electronically and information cited as deemed relevant by the authors. As a narrative review, these are representative of the authors' opinions.
