Combined Surgical Approach in the Treatment of Oculoorbital Complications of Frontal Sinus Mucocele: A Case Report

Abstract Paranasal sinus mucoceles are benign cystic masses filled with mucous content. Mucoceles are locally destructive, causing pressure on sinus walls with their resorption, allowing them to spread on adjacent structures causing local, orbital or intracranial complications. They are most commonly found in frontal sinuses. The aim of this report is to present case of oculo-orbital complications of frontal sinus mucocele, with focus on treatment using combined surgical approach. A 75-year old female patient with frontal sinus mucocele which led to destruction of orbital roof and occurrence of complications in form of orbital cellulitis and palpebral abscess was successfully treated with a combination of external frontoethmoidectomy and endoscopic sinus surgery. After initial incision of the upper eyelid abscess with drainage of purulent content, modified external frontoethmoidectomy was performed using preformed defect of orbital roof. Finally, using endoscopic sinus surgery, natural drainage of anterior group of paranasal sinuses was achieved. Various endoscopic and open approaches have been described in mucocele treatment. In this case we showed that the combined surgical approach in the treatment of frontal sinus mucoceles with destruction of sinus floor and appearance of oculo-orbital complications, provides an effective treatment and allows natural drainage of anterior group of sinuses.
