Endoscopic treatment of maxillary sinus mucocele.

Four patients with mucocele of maxillary sinus, observed between 1995 and 2001, with two years' follow-up, are described. Aim of the present study was to establish whether endoscopic marsupialization of the maxillary sinus mucocele is adequate resolutive treatment without complete removal of the mucocele wall, using more invasive approaches. The surgical procedure used was endoscopic endonasal marsupialization by a middle and/or inferior meatal antrostomy. Outcome confirms that this technique is the gold standard treatment in this disorder. In fact, complete removal of the mucocele wall is not necessary thus avoiding the risk of iatrogenic lesions of neighbouring structures in the case of a bony erosion (orbital floor, posterior wall of the maxillary sinus).
