Mini Osteoplastic Flap Through Supra-Eyebrow Incision for Primary Frontal Sinus Squamous Cell Carcinoma.

Abstract

Primary carcinoma of the frontal sinus is very rare, with an incidence of 0.3% to 1.0% of all paranasal sinus carcinomas. Although complete resection with a clear margin is definitely essential to achieve tumor control, radical surgery with osteoplastic flap using bicoronal incision has significant postoperative morbidities including scalp numbness, hair loss, and frontalis palsy. This article reports a rare case of primary frontal sinus squamous cell carcinoma extending to the orbit, which was treated successfully by mini osteoplastic flap through supra-eyebrow incision combined transnasal endoscopic approach.
