Mandibulectomy is the surgical removal of part of the lower jaw (mandible) to treat tumors that invade or abut this bone. A marginal mandibulectomy removes only the outer rim of the mandible when cortical involvement is superficial, preserving jaw continuity. A segmental mandibulectomy excises a full-thickness segment when the tumor penetrates deeply or spans a larger area, creating a gap in the jawbone.
Dr. Singhavi customizes the approach based on imaging findings (high-resolution CT or PET/CT) and biopsy results. For early lesions with limited bony contact, he selects a marginal mandibulectomy to spare as much bone as possible; for more extensive involvement, he performs a segmental resection with predefined 3D-printed cutting guides for optimal precision. Preoperative planning includes dental impressions and occlusal analysis to anticipate post-resection alignment. Intraoperatively, Dr. Singhavi uses nerve preservation techniques where feasible to minimize sensory loss. When segmental defects occur, he coordinates immediate reconstructive options—such as fibula free-flap transfer—to restore jaw continuity and prepare for future dental rehabilitation.
Under Dr. Singhavi’s care, patients achieve comprehensive tumor clearance while preserving—or promptly reconstructing—jaw function. Marginal resections often allow patients to maintain normal chewing and speech with minimal alteration. In segmental cases, immediate reconstruction reduces the risk of malocclusion and facial asymmetry, accelerating the timeline for dental implants and prosthetic rehabilitation. Overall, this targeted approach minimizes morbidity, shortens hospital stays, and enhances postoperative quality of life by restoring both form and function in a coordinated, single-stage procedure.
