Being told you need your jaw removed to treat oral cancer is one of the most frightening things a patient can hear. The immediate questions are always the same: Will my face look normal? Will I be able to eat? Will I speak properly? Will people know?
These are entirely reasonable fears — and they deserve honest, detailed answers. The good news is that jaw reconstruction has advanced enormously over the past two decades. Today, with fibula free-flap reconstruction, the majority of patients achieve near-normal facial contour, return to a largely normal diet, and go on to have dental implants that complete the rehabilitation.
In this article I want to walk through what jaw reconstruction actually involves, what recovery looks like, and what realistic outcomes you can expect — from a surgeon who performs this procedure regularly and holds the world's largest documented volume of jaw-in-a-day cancer surgeries.
Dr. Narayana Subramaniam leads the team with the largest documented volume of simultaneous jaw resection and free-flap reconstruction for cancer (jaw-in-a-day) in the world.
Why is Jaw Removal Sometimes Necessary?
When oral cancer involves the jawbone — either directly invading it or arising from the gum overlying it — removing the affected segment of the mandible (lower jaw) is necessary to achieve clear surgical margins and cure. Leaving cancer-involved bone behind leads to local recurrence and worsens survival.
The extent of jaw removal depends on the location and size of the tumour. Some patients require removal of a small segment (marginal mandibulectomy), others require a larger segment (segmental mandibulectomy), and in some cases the entire lower jaw must be removed.
What is Fibula Free-Flap Jaw Reconstruction?
The fibula is the smaller of the two bones in the lower leg. It is non-weight-bearing — meaning that removing a segment of it has minimal long-term impact on walking or running. This makes it the ideal donor bone for jaw reconstruction.
In fibula free-flap reconstruction, a segment of fibula bone is harvested along with the blood vessels that supply it and a paddle of overlying skin. This composite of bone, blood vessels, and skin is then transferred to the jaw defect, where the fibula is shaped and fixed to recreate the mandible, and the blood vessels are connected to vessels in the neck under a microscope (microvascular anastomosis).
The result is a living bone reconstruction with its own blood supply — not a prosthesis, not a plate, but actual bone that integrates and can support dental implants.
Jaw-in-a-Day — Resection and Reconstruction Together
At our centre, jaw resection and fibula free-flap reconstruction are performed simultaneously in a single operation — what we call jaw-in-a-day surgery. Two surgical teams work in parallel: one removing the tumour and preparing the jaw defect, the other harvesting the fibula from the leg.
This approach means the patient wakes up with their jaw already reconstructed. There is no period of living without a jaw, no staged procedures weeks apart, and no prolonged facial deformity.
What Does Recovery Look Like?
Dental Implants Placed
Dental implants are placed into the reconstructed fibula at the time of the original surgery — before the wound is closed. This is the jaw-in-a-day approach: tumour removed, fibula harvested, jaw reconstructed, and implants placed in a single operating session.
Intensive Monitoring
The reconstructed flap is monitored hourly for blood flow using Doppler checks. Any sign of vascular compromise is treated immediately with a return to theatre. Most flaps establish reliable circulation within 48 hours.
Early Recovery
Feeding tube in place, oral hygiene maintained, physiotherapy for the leg begins. Speech therapist introduced. Wound checks daily. Most patients are mobile within 3–4 days.
Discharge and Early Rehabilitation
Most patients are discharged at 7–10 days. Liquid diet at home, progressing to soft foods. Leg physiotherapy continues. Swelling gradually subsides over 4–6 weeks.
Adjuvant Treatment
If radiation or chemotherapy is indicated, this begins after adequate wound healing — typically 4–6 weeks post-surgery. Nutrition support throughout.
Final Denture / Prosthetic Loading
After completion of adjuvant radiotherapy and adequate healing, the final dental prosthesis (denture or implant-supported crown) is fitted — completing full oral rehabilitation. Timing varies based on radiation dose and tissue response.
Oncological Surveillance
Speech fully rehabilitated, near-normal diet established. Oncological surveillance continues with 3-monthly checks for the first 2 years.
