Paranasal Implants for Correction of Midface Concavity

Central midface concavity was corrected with the placement of porous polyethylene implants in the paranasal area. This simulated the effect of skeletal osteotomies and advancement without altering dental occlusion. Implants were placed to correct congenital, posttraumatic, and cleft related skeletal midface retrusion in nine patients. In seven of the patients, paranasal augmentation was performed in […]
