Introduction: Mucoceles originating from supraorbital ethmoid cells are difficult to treat. Due to its lateral location the endonasal approach with endoscopes is sometimes not sufficient to achieve adequate exposure and the use of extended transnasal techniques and even external approaches is required.Objectives: To determine the success rate of surgical treatment performed endonasally with endoscopes or combined, endonasal and trough a transpalpebral approach to treat mucoceles originating in supraorbital cells.Methods: Patients with mucoceles originating in supraorbital cells were treated using endonasal extended approaches to the frontal sinus and external transpalpebral approach with fat obliteration of the supraorbital cell cavity. Endoscopes were used in all.Results: Four patients had mucoceles located in supraorbital cells. All had erosion of the anterior and inferior wall of the supraorbital cell and entered the orbit, one also had erosion of the posterior wall and the mucocele capsule contacted the meningeal.The disease was resolved in all four patients, but in two of them it was necessary to perform a new combined endonasal and transpalpebral approach, with fat obliteration of the supraorbital cell due to recurrence of the mucocele.
Conclusions:The success rate with primary and revision surgery in patients treated by mucoceles located in supraorbital cells was 100%.Mucosal resection, bone drilling, and supraorbital cell obliteration with fat are part of a treatment algorithm, representing the point of greatest surgical aggressiveness.
