Mucous retention cyst of the maxillary sinus – minimally invasive treatment with use of piezosurgery. Case report

Abstract

Paranasal sinus mucoceles are chronic, benign, mucous filled cystic lesions caused by obstruction of sinus ostia. Mucoceles are usually seen in the frontoethmoidal region. Maxillary sinus retention cysts are rare amongst paranasal sinus mucoceles. We present one such case of a 63-year-old woman, whose maxillary sinus mucocele revealed during radiological examination, was treated with the use of piezosurgery. In this article we also present the beneficial aspects of the ultrasound unit, that allows for precise removal of bone with minimal risk of injury to underlying soft tissues. It allows more successful and more complication-free surgical result for a less experienced surgeon that could be especially beneficial for preparation of the Schneider’s membrane. Furthermore, it gives minimal operative invasion as well as provides less bleeding intra- and postoperative.
