[Mucoceles of the maxillary sinus. Diagnostic and therapeutic problems. Apropos of 5 cases]

Five cases of the rarely observed maxillary sinus mucocele are reported, one patient with bilateral lesions presenting primary dilatation of the bronchi. A previous history of surgery or injury to sinuses was obtained in all cases, the diagnosis being confirmed by computed tomography imaging. Recovery is usually complete after the Caldwell-Luc operation. One case with exclusion of the sinus is described and the literature reviewed.
