Partial removal
Only the affected jaw segment may be removed when disease is limited.
Mandibulectomy is a specialized surgical procedure performed to remove a portion or the entire lower jaw affected by oral cancer, jaw tumors, or aggressive bone lesions. The primary goal is to completely eliminate the disease while preserving facial appearance, speech, chewing, and swallowing as much as possible.
Mandibulectomy is the surgical removal of part or all of the mandible, or lower jawbone. Depending on the location and extent of the disease, only a small section of the jaw or a larger portion may need to be removed. The procedure is commonly performed for oral cancers involving the lower jaw, aggressive jaw tumors, and certain recurrent cystic lesions.
Only the affected jaw segment may be removed when disease is limited.
The goal is to preserve speech, chewing, swallowing, and facial contour.
It can be used for cancers, tumors, cysts, infection, and trauma in selected cases.
Mandibulectomy may be recommended for oral cancer involving the lower jaw, gingival cancer, floor of mouth cancer, advanced tongue cancer involving the mandible, squamous cell carcinoma, ameloblastoma, odontogenic keratocyst with extensive bone involvement, malignant jaw tumors, osteomyelitis resistant to treatment, and severe facial trauma requiring reconstruction.
Cancers of the lower jaw, gums, floor of mouth, or tongue may require resection.
Some tumors and cysts are non-cancerous but still invasive or recurrent.
Osteomyelitis that does not respond to treatment may need surgery.
Severe jaw injuries may require removal and rebuilding of the mandible.
The choice of procedure depends on the extent and location of the disease. Options range from marginal removal of the upper jaw segment to complete removal of the mandible in very advanced cases.
Only the upper portion of the jawbone is removed while continuity is preserved.
A complete jaw segment is removed, creating a discontinuity defect.
One side of the mandible is removed when the disease is extensive.
The entire lower jaw is removed in rare, very advanced conditions.
Consult a specialist if you experience a non-healing mouth ulcer, lower jaw swelling, loose teeth without gum disease, persistent jaw pain, difficulty chewing or swallowing, numbness of the lower lip or chin, facial asymmetry, bleeding from the mouth, or a diagnosed jaw tumor or cyst.
Persistent ulcers, bleeding, and mouth lumps should be checked early.
Swelling, facial asymmetry, and loose teeth can suggest bone involvement.
Lower lip or chin numbness may indicate nerve involvement.
Difficulty with chewing or swallowing may reflect advanced disease.
A detailed evaluation usually includes clinical examination of the oral cavity, jaw, and neck; imaging with CBCT, CT, MRI, and PET-CT for selected cases; biopsy to confirm the diagnosis; and cancer staging when oral cancer is present. This helps determine the safest and most effective operation.
The procedure is carried out under general anesthesia. The surgeon carefully removes the affected portion of the lower jaw with a safe margin of healthy tissue. In patients with oral cancer, neck dissection may be recommended if lymph node involvement is suspected. Whenever possible, immediate reconstruction is performed to restore the jaw’s shape and function.
The patient is fully asleep and comfortable during surgery.
Disease is removed along with a border of healthy tissue when needed.
Some patients need neck dissection and immediate rebuilding of the jaw.
Reconstruction is an important part of treatment and helps restore facial symmetry, speech, chewing ability, swallowing function, and jaw stability. Options may include free fibula flap reconstruction, bone grafting, titanium reconstruction plates, soft tissue flaps, and other maxillofacial reconstructive procedures.
Often used for strong bony reconstruction after segmental removal.
May help restore continuity and support jaw function.
Provide structural support in selected reconstructions.
Used to restore lining and improve healing when needed.
Recovery depends on the complexity of the surgery and reconstruction. Patients may require a hospital stay for monitoring, pain management, nutritional support, an initial soft or liquid diet, speech and swallowing therapy, and regular follow-up appointments. Most patients gradually return to daily activities with appropriate rehabilitation.
Initial monitoring and pain control are usually needed after surgery.
Soft or liquid nutrition may be needed during the early healing period.
Speech and swallowing therapy help restore function over time.
Like any major surgery, mandibulectomy carries certain risks, including bleeding, infection, swelling, temporary or permanent numbness, difficulty chewing, speech changes, delayed wound healing, and the need for additional reconstructive procedures. Careful planning and follow-up help reduce these risks.
Standard surgical risks that are monitored closely after the operation.
Temporary or permanent numbness can affect the jaw, lip, or chin.
Chewing and speech may change and often improve with rehabilitation.
Delayed healing or additional reconstruction may be needed in some cases.
We provide expertise in oral cancer and jaw surgery, advanced 3D imaging and surgical planning, specialized mandibular reconstruction techniques, comprehensive head and neck cancer care, a multidisciplinary treatment approach, and long-term rehabilitation and follow-up.
Focused care for tumors, cancers, cysts, infections, and trauma.
Imaging helps map the lesion and improve surgical precision.
Customized rebuilding aims to restore function and appearance.
Rehabilitation and follow-up help support recovery and monitor healing.
No. It may also be required for aggressive benign tumors, recurrent jaw cysts, severe infections, or major facial trauma.
Most patients regain good speech and swallowing function with reconstruction and rehabilitation.
In many cases, immediate reconstruction can be performed, depending on the patient’s condition and surgical plan.
Initial healing usually takes several weeks, while complete functional rehabilitation may take a few months.
Consult an Oral and Maxillofacial Surgeon if you have a persistent ulcer in the mouth, lower jaw swelling, unexplained loosening of teeth, a diagnosed jaw cyst or tumor, or symptoms suggestive of oral cancer. Early diagnosis offers the best chance for successful treatment and recovery.
