A technique to correct frontal sinus hypertrophy is presented. The outer table of the frontal sinus is removed and divided into three pieces with an oscillation saw. The pieces are trimmed at the margin, fixed with two microplates, and regrafted. Bilateral lateral thick portions of the supraorbital rim are shaved with a surgical burr. At the same time, a forehead lift is performed. A satisfactory result with a flat and wide forehead can be obtained by employing this technique.
