Craniofacial resection for malignant tumor of the paranasal sinuses and anterior skull base

A combined craniofacial approach is described for resection of tumors that involve the ethmoid sinuses and the adjacent base of the skull in the frontal fossa. This operation provides a more thorough en bloc excision than by conventional methods and allows adequate repair of dural defects. Reconstruction of the bony defect in the skull base is performed with a pedicelled periosteal flap from the scalp, and a skin graft.
