(A) CT with bone algorithm shows post-marginal mandibulectomy status with removal of a rim of mandible including cortex and preserved mandibular continuity and medullary cavity. (B) CT with bone algorithm shows post-segmental mandibulectomy status with removal of a segment of mandible resulting in discontinuity which has been filled with fibular graft (arrow) here (sutures are seen). (C) CECT shows post left hemimandibulectomy status with resection of one half of mandible from midline. In addition, recurrence is seen at the post-operative site.
