Mandibular Nerve Block for Trigeminal Neuralgia
Mandibular (V3) neuralgia is one of the most common causes of facial pain and it occurs in the distribution of the mandibular nerve which is the largest division of trigeminal nerve. Compression by a vascular loop around the mandibular portion of fifth nerve leading to paroxysmal painful attack in the face. The symptoms include unilateral, short-lived, severe, sharp, shooting, electric-shock like pains around the lower jaw. This pain may be triggered by innocuous stimuli such as eating, washing, shaving, and draughts of warm or cold air. Secondary causes may include cerebellopontine angle tumors and multiple sclerosis. Recently, it has been suggested that in some cases of temporomandibular joint syndrome, persistent idiopathic facial pain and myofascial pain syndrome may occur due to entrapment of the mandibular nerve.
