[Delayed endoscopic reconstruction of the anterior wall of the frontal sinus: Technical note].

INTRODUCTION

Reconstruction of the anterior wall of the frontal sinus usually requires a coronal incision. This extended approach may lead to paresthesia, unsightly scars, bruises and cicatricial alopecia. These complications encouraged several authors to endoscopic management of this kind of fractures. We present a delayed technique of reconstruction of the anterior wall of the frontal sinus by means of endoscopic hydroxyapatite filling.

TECHNICAL NOTE: Two incisions were performed behind the hair line. Subperiosteal dissection using a periosteal elevator was performed. A 30° angled endoscope was used to visualize the depression. The latter was filled by Hydroset® (Stryker, USA) as a bone substitute.

DISCUSSION: In the absence of contra-indication, the reconstruction of the anterior wall of the frontal sinus by means of endoscopic hydroxyapatite filling has many advantages including uneventful outcome, reduction of the hospital stay and a fast learning curve.
