3 years ago my inferior alveolar nerve was severely damaged due to surgical trauma. Can nerve repair help the pain?

Cross mental nerve graft has the potential of helping patients (restoration of sensation of the lip and other anatomical regions. This procedure currently available for nerve reconstruction involves microsurgery, it is a procedure called cross-face nerve grafting, a technique that uses a nerve branch from the contralateral side of the face (intact mental nerve), or other nerves, such as the inferior alveolar nerve, "connected" to a nerve graft and coapted to the damaged nerve. I recommend having a consultation with a Board Certified Plastic and Reconstructive Surgeon with expertise in Microsurgical procedures and Nerve Surgery.
