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 conjunction with rhinoplasty. There have been no implant-related complications during a mean 33-month follow-up (range 5 to 83 months). Screw fixation of these implants ensures stable positioning and allows precise final contouring during surgery. (Plast. Reconstr. Surg. 102: 1676, 1998.)
