Jaw reconstruction after cancer surgery

Mandibulectomy Reconstruction

When a section of the lower jaw is removed for cancer, the jaw loses its continuity and the chin can drift to one side. Reconstruction rebuilds the bone so the face keeps its shape and the mouth can close and chew.

Quick answer

Mandibulectomy reconstruction replaces the segment of lower jaw removed during cancer surgery. Most often a piece of the fibula, the slimmer of the two leg bones, is transferred with its own artery and vein, shaped to match the jaw and fixed with plates. This keeps the chin centred, supports the lower teeth and allows the mouth to open and close properly.

Key takeaways
  • A segmental mandibulectomy breaks the continuity of the jaw, so the remaining pieces drift out of line.
  • The fibula is commonly used because it is long, strong and can be transferred with skin attached.
  • Removing a section of the fibula usually leaves walking unaffected once healing and physiotherapy are complete.
  • Reconstructed jaw bone can later accept dental implants, which is what makes chewing on that side possible.
  • Radiotherapy after surgery affects bone healing, so timing is planned together with the oncology team.
Segmental mandibulectomy: A segmental mandibulectomy is the removal of a full thickness section of the lower jaw bone, which leaves a gap in the arch rather than a notch along its upper edge.

What mandibulectomy reconstruction involves

The lower jaw is a single curved bone that carries the lower teeth and hinges at both ends. When cancer involves the bone, a full section may have to be removed. Taking out that section leaves two loose ends, and without reconstruction they collapse inward, the chin swings towards the operated side and biting becomes almost impossible.

The usual solution is a bone flap. A length of the fibula is taken from the lower leg with its artery and vein, cut with precise wedges so it can be bent into the curve of the jaw, and fixed with titanium plates and screws. Skin attached to the same flap can line the inside of the mouth or resurface the outside of the face where needed. Vessels are then joined to vessels in the neck under a microscope.

Where bone is not required, or where a patient is not fit for a long operation, a plate alone with soft tissue cover is sometimes used instead. That is a reasonable compromise in some situations, though plates can loosen or become exposed over time, particularly after radiotherapy.

When this reconstruction is usually needed
✦Oral cancer that has grown into the lower jaw bone and needs a segment removed
✦A tumour arising within the jaw bone itself requiring full thickness removal
✦Loss of jaw continuity after an earlier operation, with the chin drifting sideways
✦Dead or infected jaw bone after radiotherapy that will not settle with medicines
✦An exposed or fractured reconstruction plate placed during a previous surgery
✦Severe injury to the jaw where bone cannot be repaired by fixation alone

Signs that need prompt review

The skin paddle of the flap turning pale, blue or cold in the early days.
A plate or screw becoming visible through the gum or the skin.
Increasing pain and swelling of the jaw with fever or a foul smell.
Calf swelling, severe leg pain or difficulty moving the foot on the donor side.

Who this operation suits

Suitability depends on the cancer plan, the condition of the leg vessels and your fitness for several hours of surgery.

May be suitable when
✦A planned removal that will leave a gap in the continuity of the jaw
✦Adequate blood supply in the leg, confirmed by examination and imaging before surgery
✦General health that allows a long anaesthetic and a monitored recovery
✦Willingness to complete physiotherapy for both the jaw and the donor leg
May not be suitable when
✦Poor circulation in the legs or previous vascular surgery affecting the donor site
✦Continued smoking or tobacco chewing, which raises flap and healing complications
✦Uncontrolled diabetes or heart and chest disease that has not been stabilised
✦Unwillingness to attend the therapy and dental steps that make chewing possible later

How the operation is planned and carried out

01
Planning and leg assessment

Scans of the jaw and the leg vessels are reviewed with the cancer surgeon. The length of bone needed is estimated, and dental treatment that will be harder after radiotherapy is completed first.

02
Removing the diseased segment

The tumour and the involved section of jaw are removed with a margin. Neck glands are usually cleared in the same sitting, which also exposes the vessels for the flap.

03
Harvesting the fibula

A second team takes a length of fibula from the lower leg with its artery, vein and, where needed, a paddle of skin. Enough bone is left at each end to keep the ankle and knee stable.

04
Shaping and fixing the jaw

The bone is cut with careful wedges so it follows the curve of the jaw, then held with titanium plates and screws. Position is checked so the teeth meet correctly.

05
Joining vessels and closing

Flap vessels are joined to neck vessels under a microscope and blood flow is confirmed. The mouth lining is repaired, drains are placed, and the leg wound is closed or grafted.

Recovery stage by stage

Day 1 to 3

Close monitoring continues with regular flap checks. The leg is elevated and the foot circulation is watched. Feeding goes through a tube and the mouth is rinsed gently as instructed.

Week 1 to 2

Swelling falls and drains are removed. Standing and walking with support usually begin in this period. Feeding by mouth restarts in stages once swallowing has been assessed.

Week 6

Bone is uniting and walking is generally comfortable without support. Soft diet is tolerated. Radiotherapy, where advised, tends to start around this stage and needs the mouth kept very clean.

Month 6 and beyond

The jaw has consolidated and facial shape has settled. Dental implants may be discussed from this point. Regular cancer follow up continues under the oncology team.

What this operation can achieve

✦Restores the continuity of the jaw so the chin stays centred rather than drifting
✦Keeps the lower face in shape instead of allowing it to collapse inward
✦Provides real bone that can later carry dental implants for chewing
✦Supports controlled mouth opening and closing, which helps speech and eating
✦Brings healthy blood supply into an area that may need radiotherapy afterwards

What results are realistic

Facial shape and jaw alignment usually improve markedly, though the reconstructed side may look slightly different and swelling settles over many months. Chewing power returns properly only after dental rehabilitation, which is a separate stage. The lower lip and chin are often numb and may stay that way. Walking generally returns to normal after physiotherapy, but a scar remains on the leg and some stiffness can linger for a while.

Risks and possible complications

Two sites are operated on in one sitting, the jaw and the leg, so risks apply to both.

Flap failure, partial or complete, which may need urgent further surgery
Plate or screw loosening or exposure, more likely after radiotherapy
Delayed bone healing or infection at the junction between old and new bone
Numbness of the lower lip and chin, which is often lasting
Wound problems, stiffness or altered walking at the leg donor site

Aftercare at home

Two areas need attention at home, the mouth and the leg, and both have simple daily routines.

✦Keep the mouth clean with the rinses advised, especially around the plates and stitches
✦Follow the diet stages given and avoid biting hard food until you are cleared
✦Do the leg exercises daily and increase walking gradually as advised
✦Stop tobacco and areca nut entirely, since bone healing depends on blood supply
✦Report any exposed plate, fever or new jaw pain rather than waiting for the next visit

Common myths, answered plainly

MythTaking bone from the leg will leave me unable to walk
In practice

A section of the fibula can usually be taken without affecting walking, provided enough is left at the ankle and knee and physiotherapy is followed.

MythA metal plate alone is just as good as new bone
In practice

A plate can bridge the gap for a while, yet without bone it may loosen or become exposed over time, particularly after radiotherapy.

MythChewing returns as soon as the jaw is rebuilt
In practice

The bone restores shape and support. Chewing power depends on dental rehabilitation, which is planned as a later stage once healing is complete.

MythNumbness of the chin means the surgery went wrong
In practice

The nerve supplying the lower lip runs inside the jaw and is often removed along with the diseased bone, so numbness is expected rather than a mistake.

Why families choose Elegance Clinic

Jaw reconstruction at Elegance Clinic in Surat is planned with the cancer team, so bone shape, bite and later dental work are considered before the first incision. The family knows the plan, the stay and the estimate in advance.

✦Leg circulation assessed carefully before the fibula is chosen as a donor site
✦Bite and future dental implants considered while the bone is being shaped
✦Physiotherapy for the jaw and the leg included within the treatment plan
✦Written estimate and expected stay explained to the family before admission
Cost & insurance

Cost and insurance

The estimate reflects the length of bone reconstructed, the plates and screws used, the hours in theatre and the days spent in a monitored bed. Cases needing skin cover both inside the mouth and on the face sit higher.

A written estimate is issued once the plan is agreed with the cancer team. Dental implants are quoted separately at a later stage. Insurance and scheme cover is common for cancer surgery.

Free flap reconstruction usually falls between Rs 1.8L and Rs 4.5L. The length of bone used, the plates required, theatre time and hospital stay all move the figure. A written estimate is prepared before admission once the plan is settled.

A section of the fibula can generally be removed without lasting effect on walking, since the larger leg bone carries the weight. Enough bone is left at the ankle and knee, and physiotherapy restores confidence over several weeks.

Feeding is by tube at first, then soft food once swallowing has been checked, usually within the first two weeks. Chewing firmer food comes much later and often depends on dental rehabilitation after the bone has fully healed.

Rebuilding the jaw keeps the chin centred and preserves lower face shape, which is a large improvement over leaving the gap. Some asymmetry usually remains, and swelling can take several months to settle completely.

Diabetes is not a barrier by itself, provided blood sugar is well controlled before surgery. Poorly controlled sugar raises the risk of infection and delayed healing, so the physician stabilises it before a date is fixed.

Radiotherapy usually starts once wounds have healed, commonly around four to six weeks afterwards, with the exact timing set by the oncology team. Dental work that would be difficult later is completed before radiotherapy begins.

The jaw and mouth are examined, scans and biopsy reports are reviewed, and the leg circulation is assessed. The operation, the donor site, the likely stay and later dental steps are explained, and a written estimate follows.
