Abstract
INTRODUCTION:Trigeminal neuralgia produces a great limitation in the quality of life of patients suffering from this condition. It is necessary an adequate knowledge of its clinical characteristics to differentiate it from other causes of facial pain that are more frequent and to avoid unnecessary and irreversible treatments such as tooth extraction.
OBJECTIVE:To describe the most important aspects in the diagnosis and treatment of patients with trigeminal neuralgia.
METHODOLOGY:Narrative review.
DEVELOPMENT:Trigeminal neuralgia is characterized by recurrent episodes of unilateral, severe, brief, and penetrating facial pain that follows the distribution of the trigeminal nerve. There is a classic form in which vascular contact is recognized on the trigeminal nerve, an idiopathic form without known etiology and a secondary form due to conditions such as multiple sclerosis, tumors, arteriovenous malformations, among others. The diagnosis is based mainly on the clinical characteristics, although magnetic resonance imaging is an aid in selected cases. Carbamazepine and oxcarbazepine are the first line of treatment, while other medications with a lower level of evidence are part of the second line of treatment. For refractory cases, there are surgical alternatives, among which is microvascular decompression, percutaneous radiofrequency rhizotomy, percutaneous glycerol rhizotomy, percutaneous balloon compression, and stereotactic radiosurgery.
CONCLUSIONS:The approach of trigeminal neuralgia requires knowing its clinical characteristics and choosing the most appropriate treatment for the patient through multidisciplinary work.
