Is this cosmetic jaw surgery?
No. It repairs a structural defect in the lower jaw.
It differs from jawline implants, which mainly change contour, and corrective jaw surgery, which moves existing jaw bones to improve alignment.
Reconstructive Surgery • Face
Mandibular Reconstruction
Mandibular reconstruction rebuilds missing or damaged lower-jaw bone and nearby tissue to support facial structure and functions such as chewing and speaking.
Will I need tissue from elsewhere?
Sometimes, especially when a larger segment of jaw is missing.
Surgeons may transfer bone and soft tissue with their blood vessels from another area, often the lower leg. Smaller defects may have other options.
Will reconstruction restore my teeth?
Rebuilding the jaw and replacing teeth are related but separate steps.
Dental implants or a removable prosthesis may be considered later. Cancer treatment, bone healing and tissue health can affect what is possible.
01 · Overview
Rebuilding the lower jaw
The mandible is the lower-jaw bone. Reconstruction may be needed after cancer removal, serious injury, infection or damage related to radiation treatment. The plan depends on how much bone is missing and whether the mouth lining, skin or other soft tissue also needs repair. [1]
Reconstruction may use a plate, a bone graft or a transfer of living bone and soft tissue called a vascularized free flap. With a free flap, the surgeon connects small blood vessels in the transferred tissue to vessels in the neck. The goal is a stable foundation that supports healing and rehabilitation. [1]
This is not the same as mandibulectomy, which removes part or all of the lower jaw. Reconstruction repairs the resulting defect and may happen during the same operation or later. Care may involve reconstructive and head-and-neck surgeons, dental specialists, speech and swallowing therapists, and nutrition support. [2]
- Main purpose
- Restore lower-jaw structure and support function
- Anesthesia
- Usually general anesthesia
- Care setting
- Hospital care, often with an inpatient stay
- Recovery
- Often months, with staged rehabilitation
Why does the location of the defect matter?
The front of the jaw helps support the chin, lower lip and tongue, while the sides contribute to chewing and alignment. The size and location of missing bone, remaining teeth and condition of nearby tissue all influence the repair.
Can reconstruction happen during cancer surgery?
Often it can, but not always. Your team considers cancer clearance, your overall health, infection, prior radiation and any treatment still needed. Delayed reconstruction may be recommended when it offers a safer or more practical path.
02 · Concerns & Goals
What reconstruction may address
A lower-jaw injury or loss of bone can affect both daily activities and appearance. Your priorities help guide a plan that also protects your health.
Chewing and bite
Missing bone or teeth can make chewing difficult and change how the jaws meet. Bone repair may help, but dental treatment and rehabilitation may also be needed.
Speech and swallowing
Changes to the jaw, tongue support or mouth lining can affect clear speech and safe swallowing. Therapy and nutrition planning may be part of care.
Facial support
Loss of jaw structure can change the chin, jawline and lower-lip position. Reconstruction aims to restore support, although some asymmetry may remain.
Damaged or poorly healing tissue
Infection, previous surgery or radiation can leave tissue less able to heal. Healthy tissue transfer may be considered after the underlying problem is assessed.
03 · Options
How the approaches differ
These approaches are not interchangeable. Your surgeon recommends a repair based on the defect, blood supply, surrounding tissue, health history and longer-term dental goals.
Vascularized bone free flap
Living bone is transferred with its own blood supply.
How it worksBone, often from the fibula in the lower leg, is shaped to rebuild the jaw. Skin or other tissue may be included, and small blood vessels are connected in the neck.
May suitOften considered for larger gaps or defects that also need soft-tissue replacement.
Main tradeoffIt is a major operation with recovery at both the jaw and the donor site, plus close monitoring of the flap's circulation.
Bone graft reconstruction
A bone graft repairs a selected defect without a direct blood-vessel connection.
How it worksBone is placed into the defect and secured while it heals into the surrounding jaw.
May suitMay suit smaller defects with healthy surrounding tissue and a reliable blood supply.
Main tradeoffThe graft may not fully heal or may lose volume. It is generally less suitable for large gaps or heavily damaged tissue.
Plate-based reconstruction
A reconstruction plate supports or bridges the jaw.
How it worksA metal plate is fixed to remaining bone, sometimes with soft-tissue coverage. Plates also commonly stabilize bone flaps or grafts.
May suitMay be used as a temporary bridge or in selected patients when bone transfer is not appropriate.
Main tradeoffA plate alone does not replace living bone or provide the same foundation for dental implants. Exposure, loosening or breakage can require further surgery.
Soft-tissue reconstruction
Transferred tissue repairs the lining, coverage or bulk around the jaw.
How it worksA local flap, regional flap or free flap replaces missing soft tissue, sometimes alongside a plate or bone reconstruction.
May suitMay suit defects mainly involving soft tissue or selected situations where rebuilding bone is not feasible.
Main tradeoffSoft tissue alone does not restore the strength of missing jaw bone. Bite, contour and dental limitations may remain.
The safest approach may differ from the most extensive repair. Ask how your cancer treatment, circulation, tissue quality and dental goals affect the recommendation. [1] [2].
Does computer planning change the operation?
CT-based planning, cutting guides and custom plates may help surgeons plan bone shape and alignment. These tools support surgical judgment; they do not remove healing risks or guarantee a particular result.
How is the donor site chosen?
The team considers how much bone and skin are needed, the shape of the defect and the health of possible donor sites. Leg circulation, walking ability and previous operations may affect whether a fibula flap is suitable. Other options can include bone from the shoulder-blade area or pelvis.
04 · Results
What may improve and what may remain
A stable foundation
The first priority is healthy tissue and a jaw repair that heals.
- Bone healing and flap survival are assessed through examinations and, when needed, imaging.
- Infection, radiation effects or poor circulation can delay healing or require another operation.
Function develops over time
Chewing, speech and swallowing may improve through reconstruction and rehabilitation.
- Progress depends on remaining teeth, tongue function, nerve health and the amount of tissue removed.
- Some people continue to need a modified diet, therapy or feeding support.
Contour and dental planning
Facial support may improve, but appearance and tooth replacement often require separate discussions.
- Swelling settles gradually, and scars, numbness or asymmetry may persist.
- Dental implants, prostheses or contour adjustments may be considered after healing and any additional cancer treatment.
Reconstruction cannot always restore the jaw to its previous appearance or function. Ask your team to explain the likely benefits and lasting limitations for your specific defect. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery varies widely with the size of the repair, donor site and other treatments. Your surgical team will provide an individualized plan for breathing, feeding, mouth care, movement and wound care.
Step 1 · Surgery and immediate monitoring
Treatment day
After general anesthesia, you are monitored in the hospital. Major reconstruction may involve drains, a feeding tube and temporary breathing support. Free flaps need frequent circulation checks.
Step 2 · First several days or longer
Early hospital recovery
Care focuses on pain control, tissue circulation, nutrition and safe movement. The team assesses swallowing and donor-site needs before deciding when you can leave the hospital.
Step 3 · Following weeks
Healing at home
Fatigue, swelling and restricted eating may continue. Follow-up checks guide wound care, diet changes and activity. Ask your surgical team whether compresses are appropriate and exactly how to use them.
Step 4 · Following months
Rehabilitation and next steps
Bone healing, speech and swallowing therapy, and donor-site rehabilitation may continue. Dental restoration or additional surgery is considered when healing and the wider treatment plan allow.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Eating and drinkingPlanning context: Your team determines when swallowing is safe and what food texture is appropriate. [2]What affects it: Jaw stability, mouth wounds and swallowing function may require tube feeding or a modified diet.
Work and daily responsibilitiesPlanning context: Major reconstruction may require several weeks or longer away from work.What affects it: Fatigue, speech needs, feeding support and additional treatment affect timing. Returning to work does not mean healing is complete.
Walking and exercisePlanning context: Movement is usually introduced with guidance; restrictions depend on the repair and donor site.What affects it: A leg donor site may require support, specific weight-bearing limits or physical therapy.
DrivingPlanning context: Resume only after your team clears you and you can drive safely without sedating medication.What affects it: Neck movement, alertness and the ability to brake safely may be affected.
Use your discharge instructions rather than a general timetable. Ask which restrictions apply to your jaw, neck and donor site separately.
Before your procedure
- Discuss the defect, reconstruction goals and timing of any cancer or infection treatment.
- Review all medicines and supplements, including blood thinners; change them only as directed.
- Tell the team about nicotine use and ask for help stopping before and after surgery.
- Complete requested imaging, dental review and donor-site circulation testing.
- Discuss nutrition, swallowing and the possibility of temporary feeding or breathing support.
- Arrange transportation, home support and a clear way to contact the surgical team after discharge.
Will I need a feeding tube or tracheostomy?
Some larger reconstructions require temporary tube feeding or a tracheostomy, an opening in the neck that supports breathing. Neither is required for every patient. Ask why either may be needed and what must happen before it can be removed.
What happens to the area where bone is taken?
The donor site has its own wound, scar and recovery needs. Depending on the site, you may have swelling, weakness, altered sensation or movement limitations. A skin graft or physical therapy may be needed.
06 · Safety
Risks and what your clinician assesses
Swelling, bruising, soreness, fatigue and altered sensation are common early experiences. Mouth opening and eating may be limited. Symptoms should be followed by your team rather than assumed to be normal if they are worsening.
Bleeding or fluid collection
Bleeding, a blood collection or fluid buildup can require drainage, transfusion or another operation.
Infection or wound breakdown
Wounds can become infected or open. Saliva may leak through a wound, creating a fistula that needs treatment.
Flap or graft loss
Poor blood flow can damage transferred tissue, and a graft may fail to heal. A threatened free flap can require urgent surgery.
Bone or hardware problems
Bone may heal slowly, fail to join or heal out of alignment. Plates or screws can become exposed, loose or broken.
Lasting functional or donor-site changes
Numbness, weakness, bite changes, limited mouth opening, swallowing difficulty or asymmetry may persist. Tissue donation can also cause lasting discomfort or movement changes.
Anesthesia and major-surgery complications
Risks include medication reactions, breathing or heart problems and blood clots in the legs or lungs. Your health history affects these risks.
Discuss these risks and your individual health history with your surgeon. [1]
What your clinician assesses
- The amount and location of missing bone, remaining teeth and soft-tissue needs
- Cancer status, infection, prior radiation and previous operations
- Nutrition, nicotine use, diabetes, circulation and heart or lung health
- Donor-site suitability, rehabilitation needs and support at home

08 · Questions
Common questions
Can I have dental implants in the rebuilt jaw?
Possibly. The bone type and position, soft tissue, healing and radiation history all matter. Some teams plan implants during reconstruction; others wait. Dental assessment should be part of early planning when tooth replacement is a goal.
Will my jaw look the same as before?
Reconstruction aims to restore support and shape, but an exact match is not assured. The size of the defect, soft-tissue changes, scars and radiation can affect appearance.
Can reconstruction be done after radiation?
Yes, in selected patients, but radiation can reduce tissue healing and increase complications. Your surgeon may recommend transferring healthy tissue with its own blood supply and coordinating closely with your cancer team.
Is a second operation always needed?
No, but treatment is often staged. Dental restoration, contour adjustments or treatment of healing problems may involve additional procedures. Ask which stages are planned and which would be considered only if needed.
