A mandibulectomy is an operation to remove part or all of the lower jawbone — the mandible — when cancer has spread into the bone or started there. It is most often performed for oral cancers that have reached the jaw. The goal is to remove all of the disease with a safe margin of healthy tissue while protecting as much of your ability to eat, speak, and the appearance of your face as possible.
At CION Cancer Clinics, the surgery is never decided by a single doctor. Your case is reviewed by a multi-disciplinary tumour board — surgical, medical, and radiation oncologists together — so the plan is matched to your specific scans and biopsy. Costs are explained clearly before treatment begins, and we order no unnecessary tests.

India accounts for about one-third of the world's oral cancer cases, and many are linked to chewing tobacco and areca nut, which are widely used across Telangana and Andhra Pradesh. When oral cancers reach the jawbone, a mandibulectomy may be needed to remove the disease completely. Source: ICMR National Cancer Registry Programme (NCRP).
Removes only the affected part of the jawbone while keeping the lower edge of the jaw intact, so the jaw stays in one continuous piece. It is chosen when the cancer involves the bone superficially.
Removes a full-thickness section of the jaw when the cancer has invaded the bone more deeply. This usually needs reconstruction to restore the shape and function of the jaw.

Start Your Story. Book Free Consultation.A mandibulectomy is surgery to remove part or all of the lower jawbone (the mandible) when cancer has spread to or started in the bone. At CION Cancer Clinics, the operation is planned by a tumour board so the team removes the disease with a safe margin while protecting as much function as possible. Whether you need a marginal or a segmental procedure depends on how far the cancer has reached, which is confirmed on imaging and biopsy before surgery.
A marginal mandibulectomy removes only the affected part of the jawbone while keeping the lower edge intact, so the jaw stays in one piece. A segmental mandibulectomy removes a full-thickness section of the jaw, which usually needs reconstruction to restore shape and function. The choice is made by the surgical oncology team based on imaging that shows how deeply the cancer involves the bone.
In most cases reconstruction is performed in the same operation, immediately after the cancer is removed. Reconstructing the jaw helps restore the ability to chew, speak, and the appearance of the face. The reconstruction plan is decided in advance by the tumour board so that the cancer team and the reconstructive team work together during one anaesthetic where possible.
Most patients regain the ability to eat and speak, though recovery takes time and rehabilitation. Speech therapy and a nutrition team support you through the healing period, and reconstruction is planned to protect chewing and speech function. Your care team will explain what to expect for your specific surgery during your 45-minute consultation, so there are no rushed decisions.
