Abstract:
Chordoma is a rare malignant intercranial tumor. Cranial base chordomas usually occur extradurally. In the current study, a 44-year-old man with chordoma in cranial base and paranasal sinuses was reported. The patient was managed with combination of surgery and radiotherapy. Surgical phase comprised anterior cranial base osteotomy, removal of lesions, and replacement of osteotomy segment. One-year follow-up showed no evidence of recurrence of lesions. Aggressive surgery with postoperative radiotherapy for treatment of chordoma in the cranial base can be suggested as a proper treatment modality.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
