Suction dissector device for sinus membrane elevation.

The maxillary sinus floor augmentation technique requires lifting of the sinus membrane with a series of curved elevators. Lifting of the sinus membrane can be difficult due to the presence of bleeding, requiring the alternate use of curved elevators and the aspirator. This technical note presents a new surgical device, a suction dissector specifically designed for sinus membrane elevation. The suction dissector has a curvature similar to that of the curved dissector commonly used for lifting of the sinus membrane and contains an internal channel that allows the aspiration of liquid.
