Clinical Guidelines on Mandibular Surgery
Cancers or tumors in the lower jaw (mandible) require absolute surgical precision. The surgery must balance complete tumor removal to prevent recurrence with state-of-the-art reconstruction to restore normal chewing, swallowing, speech, and facial symmetry.
1. Staging and Tumor Scope
Cancers of the lower jaw often start in the lower gums (alveolus) or spread from the floor of the mouth/cheek. Staging is determined using high-resolution CT scans or MRI to measure how deeply the tumor has invaded the bone. Benign but locally aggressive tumors, such as Ameloblastoma, do not spread to other organs but require wide surgical margins to prevent them from growing back and damaging the jaw.
2. Mandiblectomy and Margin Clearance
A Mandiblectomy involves removing the affected portion of the lower jaw bone. * Marginal Mandiblectomy: Used when the tumor lies close to the bone but has not invaded it. Only the upper rim of the jawbone is removed, preserving the lower bony border and jaw continuity. * Segmental Mandiblectomy: Required when the tumor has invaded the bone. A complete segment of the jawbone is removed, requiring immediate reconstruction to bridge the gap.
3. Leg Bone (Fibula) Free Flap Reconstruction
To restore the shape and strength of the jaw, Dr. Saha performs Fibula Free Flap Reconstruction. A portion of the calf bone (fibula) along with its blood vessels is harvested. The bone is carefully shaped using 3D templates to match the missing jaw segment. Its blood vessels are connected to vessels in the neck using microvascular surgery. This healthy bone tissue provides a solid foundation for facial appearance and future dental implants.
