The marginal mandibular nerve is a branch of the facial nerve that provides sensory innervation to the lower lip, the mandible (jawbone), and the skin of the chin. It is also involved in the motor control of the muscles used for speaking and smiling.

Damage to the marginal mandibular nerve can result in weakness or paralysis of the muscles innervated by the nerve, leading to difficulty with speaking and smiling. This type of nerve damage can occur as a result of facial trauma, surgery, or certain medical conditions.

Treatment for marginal mandibular nerve damage may include physical therapy to help improve muscle function and speech therapy to help with any difficulties with speaking. In some cases, surgical intervention may be necessary to repair or reconstruct the damaged nerve.
