Mandibular Nerve Entrapment
The mandibular nerve (MN) the V3 branch of the trigeminal ganglion, innervates the sensory branches of the lower face. The nerve can be entrapped in the area of foramen ovale or mental foramen, as well as by anatomical changes due to mandible fracture, dental trauma, vascular anomaly, fibrous dysplasia, scar tissue, and schwannoma, causing unilateral facial pain. Proper diagnosis and injection and/or surgical treatment can lead to improvement of symptoms.
