There are occasions, in diseases of the frontal sinus, when wide exposure of the sinus without frontal duct or ethmoid sinus exploration is indicated. Such a situation exists with a large osteoma of the frontal sinus.
Classical approaches, as with the Lynch1 and Killian2 operations, sacrifice cortical bone in order to obtain exposure. Secondary operations for correcting the depression left by removal of the anterior wall, either by use of autogenous or alloplastic materials,3-6 leave much to be desired. The use of the coronal hairline incision7 with attached bone flap seems to be too radical an approach and, of course, in a bald person would give a visible scar.
We will describe a method which uses a direct skin approach and which, by creating a trap door of the anterior wall of the sinus, gives adequate exposure without sacrifice of any cortical bone and, consequently, with
