[Mucoceles of the maxillary sinus].

The term mucocele designates a cyst developing from a sinus mucosa, generally the frontal and/or ethmoidal sinuses. They present clinically as a benign tumor, and their diagnosis and treatment is usually simple. Maxillary sinus localizations are exceptional, however, and raise numerous problems in daily practice. Three cases of maxillary sinus mucoceles are reported.
