Treatment of Frontal Sinus-Supraorbital Cell Mucocele: Endoscopic Surgery with Trephination & Transillumination Technique: Case Report / 대한이비인후과학회지

ABSTRACT

Mucoceles of the paranasal sinuses are chronic expanding lesions containing inspissated mucus, which occurs when sinus ostium is obstructed. A variety of conservative and radical surgical procedures have been introduced, with each approach having advantages as well as disadvantages. Diseased frontal sinus mucosa and bone were commonly ablated by radical frontal sinus surgery such as osteoplastic flap surgery in the past. During the last decade, endoscopic sinus surgery has become the major choice for the treatment of paranasal sinus mucoceles, and the technique of endoscopic sinus marsupialization has been considered non-invasive and successful. But the technique has limitation in cases with small frontal recess or mucocele in the lateral portion of the frontal sinus which is not accessible via the nose, and hypertrophic mucosa obstructing the entire sinus. A 52-year-old man was presented with a supraorbital cell mucocele located in the lateral side of frontal sinus mucocele, which could not be treated by endoscopic surgery alone. Endoscopic surgery with sinus marsupialization, trephination and transillumination technique was introduced. We report this case with a review of related literatures.
