Role of bi-portal endoscopic approach to frontal sinus in managing frontal sinus diseases

Abstract

Background In spite of recent evolution of endoscopic frontal sinus surgery, some cases are still challenging due to the difficulty to reach the lateral frontal sinus even with Draf type III. This study aims to highlight the bi-portal approach to the frontal sinus disease. Materials and methods This study is a prospective study that was conducted on four patients with mean age of 56 years. Two cases were presented with allergic fungal sinusitis, one case showed an inverted papilloma and a single case of granulomatous fungal sinusitis. All patients underwent bi-portal surgery which entailed endoscopic frontal sinus surgery either Draf IIb or III plus as an external approach through the upper eyelid. Results Complete removal of the disease with no major postoperative complications, with no detection of recurrence during the 12–30-month-follow-up period. Conclusion Bi-portal frontal sinus approach is an easy noninjurious technique with very little cosmetic drawbacks allowing rhinologists to access the whole aspects of the frontal sinus, especially the lateral part.
