Mucocele is a disease lined primarily by epithelium, and occurs mainly when the sinus ostium is obstructed.
We report a case of a 37-year-old man who presented with painless proptosis of the right eye and diplopia.
The preoperative finding was mucocele of the ethmoid sinus.
We performed endoscopic sinus surgery, which included uncapping of the anterior and superior wall of the mucocele.
The mucocele was treated safely and effectively without touching the medial orbital wall.
Clinicians should note that minimally invasive surgery to remove ethmoid mucoceles is relatively straightforward and can prevent the various complications associated with these lesions.
