Can mandibular angle osteotomy repair inferior alveolar nerve damage?

The primary purpose of mandibular angle osteotomy for cosmetic reshaping is usually aesthetic improvement. If the mandibular canal injury is minor, it may be secondarily repaired; however, when the injury to the mandibular canal is severe or accompanied by other complications, repair may not be feasible. If there are any concerns, it is recommended to seek medical consultation in advance. Detailed analysis is as follows:

During mandibular angle osteotomy for reshaping, which involves adjusting the mandibular structure, the exposure or protection of the mandibular canal may be involved. For example, when excessive enlargement of the mandibular angle causes compression of the mandibular canal, osteotomy can adjust the position and structure of the mandible, thereby relieving pressure on the mandibular canal. During the surgical procedure, the surgeon must operate carefully to ensure the mandibular canal is not directly damaged and to protect the surrounding soft tissues as much as possible. This surgical approach must be performed by experienced surgeons to ensure the safety and effectiveness of the operation.

However, if there is severe damage to the mandibular canal or associated complications, mandibular angle osteotomy may not be able to repair the injury. Severe damage to the mandibular canal may be accompanied by significant impairment of nerve function, which may require more delicate neurosurgical procedures for repair. Additionally, if infection, bleeding, or other serious complications are present, the surgical risk increases, and mandibular angle osteotomy would not be appropriate. In such cases, physicians typically prioritize conservative treatment, nerve repair surgery, or other safer surgical approaches.

In addition to direct surgical repair, patients may also receive postoperative adjunctive treatments such as facial muscle exercises, massage, and electrical stimulation to promote recovery of nerve function.
