The intranasal approach for mucoceles of the sinuses represents an advance in the techniques of sinus surgery. The object of our study is to show the value of this type of surgery by reviewing 16 cases of fronto-ethmoidal mucoceles undergoing surgery in our department. The approach was purely intranasal. Surgery consisted of wide marsupialisation of the nasal cavities. The immediate postoperative progress was good. There were no complication in this series; neither was there any recurrence. The follow up period was from 3 months to 5 years. As the follow-up period was too short in some of the cases, no firm conclusions can be drawn. Yet despite this limitation, it seems that the intranasal approach is to be preferred in dealing with mucoceles of the sinuses.
