Jaw reconstruction surgery

Overview

Jaw reconstruction surgery is a specialized surgical procedure used to restore the structure, function, and appearance of the jaw when the jawbone has been severely damaged, removed, or developed abnormally. It may involve reconstruction of the lower jaw (mandible), upper jaw (maxilla), or both.

Common Causes

Jaw reconstruction may be required due to: Trauma and accidents Severe facial injuries, fractures, or loss of jawbone caused by road accidents, falls, or other trauma. Cancer and tumors Removal of tumors or oral cancers may require removal of part of the jawbone, followed by reconstruction. Congenital conditions Some people are born with abnormalities affecting the development or shape of the jaw. Severe infections Serious infections can destroy jawbone and surrounding tissues. Osteonecrosis or bone damage Loss of blood supply or certain medical conditions can lead to jawbone deterioration. Severe bone loss Significant bone loss may occur due to disease, previous surgery, or other conditions and can affect chewing and dental function.

Types of Treatment

The appropriate treatment depends on the cause, location, and extent of jaw damage. Bone grafting: Bone is taken from another area of the body or obtained from a donor/biocompatible source to rebuild the jaw. Free flap reconstruction: A piece of bone and tissue, often from the leg, forearm, or hip area, is transferred to reconstruct the jaw and restore soft tissue. Plates and screws: Titanium plates and screws may be used to stabilize reconstructed or fractured sections of the jaw. Dental implants: After sufficient healing, dental implants may be placed to replace missing teeth and improve chewing. Prosthetic reconstruction: Customized prostheses may be used in selected cases. Orthognathic surgery: If the primary problem is abnormal jaw position or alignment, corrective jaw surgery may be performed. Soft-tissue reconstruction: Skin, muscle, or other tissue may be reconstructed along with the jawbone when necessary.

Recovery

Recovery varies depending on the complexity of the surgery. Patients may initially require a liquid or soft diet, pain management, and careful oral hygiene. Healing can take several weeks to months, and additional procedures—such as dental implants or further corrective surgery—may be needed later.
