Obliteration and Contouring of Comminuted Anterior Wall Frontal Sinus Fracture Using Pericranial Flaps.

Abstract

Summary:One of the common postoperative complications of comminuted fractures of frontal sinus are contour deformity, hardware extrusion, adherence and/or palpability, and skin thinning. We are presenting our novel technique with pericranial flaps to decrease these complications. The study was performed from January 2019 to January 2020, on 40 cases of comminuted fractures of anterior wall of frontal sinus, 28 men and 12 women, with an average age of 41 years. Injury resulted from motor vehicle crashes (n = 25), motorcycle crashes (n = 11), and falling from heights (n = 4). Our novel technique involves the use of two anteriorly based pericranial flaps; one flap is used for obliteration of the frontal sinus and the other is used to overlay the hardware used to restore forehead contouring and to eliminate the possibility of early extrusion or late plates or mesh palpability. Two patients had postoperative minimal disruption of forehead lacerations healed with secondary intention and minimal scarring. Excellent patient compliance without any complaint of mesh palpability. No adherence occurred and no skin thinning. This technique (two anteriorly based pericranial flaps) may be more reliable to obliterate the frontal sinus also overlaying the hardware used to improve forehead contour and decrease the incidence of mesh palpability and skin adherence than using hardware without flap coverage.
