Abstract
Mental nerve neuralgia is a painful disorder in the distribution of the mental nerve. The first description of mental nerve neuropathy was given by Charles Bell in 1830, who reported the phenomenon in a patient with advanced breast cancer due to a bony metastasis in her left mandible [1]. Mental nerve neuropathy, which has also been called Numb Chin Syndrome is a purely sensory neuropathy identified by paraesthesia or numbness in the lower lip and chin. The clinical presentations are paraesthesia (tingling/burning/pins and needles) localised to a discrete area of the lower maxillary/mandibular region of the face, patients experiences a numb/swollen lower lip, loss of sensitivity may lead to inadvertent biting, or injury to the lower lip, symptoms are predominantly unilateral; however bilateral symptoms may also be present [2].
