Aesthetic correction of hypertrophic frontal sinus with beveled osteotomy.

The authors performed aesthetic correction of hypertrophic frontal sinus in 3 patients with protruded supraorbital region by using beveled osteotomy. Under general anesthesia, a bicoronal incision was performed followed by dissection through the subgaleal plane to the supraorbital ridge. Subsequently, the anterior wall of the frontal sinus was sectioned with a reciprocating saw and an osteotome by using the beveled osteotomy technique. Beveled osteotomy is a technique applied during sectioning of the anterior wall of the frontal sinus whereby the upper portion of the sinus remains intact and the lower portion of the sinus is changed. The technique used by the authors differed from the conventional method in that the existing shape of the outer wall of the frontal sinus was preserved when osteotomy was performed. This technique therefore preserves a more natural contour of the forehead and is advantageous in that it does not require additional interventions.
