Experience of maxillary sinus floor augmentation in the presence of antral pseudocysts

Abstract

Sinus floor elevation is increasingly being used with implant placement procedures. However, certain surgical difficulties can develop, such as sinus membrane perforation, bleeding, anatomic variations, or some pathologies of the maxillary sinus. Maxillary antral pseudocysts are one of the most common benign pathologies of the maxillary sinus. Although some investigators have described the presence of this pathology as a contraindication, recent reports have demonstrated that pseudocysts of the maxillary sinus are not a contraindication for sinus augmentation. In these reports, maxillary sinus augmentations related to antral pseudocyst experiences are presented.
