Fronto-orbital mucoceles: our experience.

Frontal sinus mucoceles are rare benign neoplasms that can result in bony erosion extending from the borders of the sinus into the orbital cavity. The authors report the fronto-orbital mucoceles they have observed in the last 8 years. The authors used an "open surgery" approach in 12 fronto-orbital mucoceles, characterized by an osteoplastic frontal flap, through a coronal incision or Lynch incision. In this way, they were able to expose the frontal sinus and to remove completely the mucocele from the periorbita. Only one recurrence is reported 2 years after surgery. Excellent aesthetic results have been reached in all cases. In the literature, many different positions are reported for the treatment of mucoceles. The endoscopic surgery of the paranasal sinuses has become the procedure of choice for mucoceles of maxillary, ethmoidal, and sphenoidal sinuses. However, few authors have recommended the endoscopic approach for frontal mucoceles. The indications and limitations of endoscopic and "open" surgery are critically discussed in the light of the authors' personal experience and current literature.
