Augmentation of the craniofacial skeleton with porous hydroxyapatite granules (Interpore 200) has been performed in 52 sites on 43 patients. Follow-up extends to 5 years, and 26 patients have been followed for greater than 1 year with excellent results. The procedure has been used for reconstruction of congenital and posttraumatic deformities and for purely aesthetic purposes. Areas that have benefited from hydroxyapatite augmentation include the skull, zygomaticomaxillary region, lateral mandible, perialar region, periorbital area, and temporal region. There have been no cases of infection, and only two patients have required minor revisions. Resorption has not occurred.
