A Practical Review of Trigeminal Neuralgia

Abstract

Trigeminal neuralgia (TN) is a highly disabling disorder characterized by very severe, brief, electric shocks, like recurrent episodes of facial pain. New diagnostic criteria classifying TN on the basis of the presence of trigeminal neurovascular conflict or an underlying neurological disorder can help better characterize patients and determine treatments. Magnetic resonance imaging using specific sequences should be a part of the diagnostic workup to detect a possible neurovascular contact and exclude secondary causes. Carbamazepine and oxcarbazepine are drugs of first choice for long-term treatment, whereas microvascular decompression is the first-line surgical management of medically refractory patients. This review aimed to review the classification, clinical features, pathophysiology, diagnostic approaches, and management of TN.
