Sinus lift, antral pseudocyst removal and horizontal bone augmentation using a bony lid - Case report

Purposes: Complex cases often require various treatment modalities that increase patients morbidity, treatment time and costs. In the present case we combined severaltechniques in order to perform a sinus lift, remove an antral pseudocyst and augmentthe site horizontally.Case report : A 69 year old female patient presented herself at our office looking for anoral rehabilitation solution. A need for sinus grafting as well a horizontal augmentationwas noticed. An antral pseudocyst occupied a large portion of the right sinus. We removed a bony lid to access the sinus, aspirated the antral pseudocyst´s content andremoved it through the Schneiderian membrane. After suturing it, the membrane waselevated, the sinus lift performed and the access window closed with a collagen membrane. The bony lid was used to augment the adjacent area. Implants were placed 4 months later.Conclusions : With the present method of treatment we were able to successfully perform a sinus lift, antral pseudocyst removal and bone augmentation, with a low morbidity, combined approach.
