A Reconstructive Transbasal Approach to Tumors Involving the Anterior Skull Base

ABSTRACT

An en bloc bilateral osteotomy of the orbital roofs and frontal sinus for large or deeply situated anterior skull base tumors offers less brain retraction and a wide exposure. The authors describe en bloc bilateral osteotomy of the orbital roofs and frontal sinus, with skull base reconstruction using inner table of the patient's own frontal bone flap. The approach in this report offers the advantage of wide exposure, one-site operation and short operation time.
