The authors have previously advocated a supraorbital approach to tumors of the orbit. In this paper, they describe a technique in which they take advantage of a large frontal sinus as a means of entering the orbit without the necessity of intracranial exposure, as required by the more conventional supraorbital approach. This is achieved without frontal burr holes, allowing for a superior cosmetic result. The anterior wall of the frontal sinus is removed, and with it the roof of the orbit as a single bone flap. A case in which this technique was used is described.
