Craniofacial resection for malignant tumors of ethmoid and anterior skull base

A combined craniofacial approach is described for resection of tumors that involve the ethmoid sinuses and adjacent base of the skull in the frontal fossa. This operation provides a more thorough en bloc excision than by conventional methods with reasonable safety since both the neurosurgeon and the head and neck surgeon are guided by each other during the mobilization of the specimen, and adequate repair of dural defects can be accomplished. Reconstruction of the bony defect in the skull base is performed with a pedicled periosteal flap from the scalp and a skin graft.
