The Fate of Porous Hydroxyapatite Granules Used in Facial Skeletal Augmentation

This study evaluated the long-term maintenance of augmented bony projection
when porous hydroxyapatite granules are used on the facial skeleton. Ten female patients aged 28–58 years were studied following
aesthetic augmentation of the facial skeleton at 24 sites using porous hydroxyapatite granules. Postoperative CT scans at
3 months served as the baseline measurement and compared with scans taken at 1 and 2 years, with the thickness of the hydroxyapatite
measured in axial and coronal planes. Thickness of original bone plus overlay of hydroxyapatite, thickness of the overlying
soft tissue, and the overall projection (bone plus soft tissue) were recorded. It was found that 99.7% of the hydroxyapatite
was maintained at 2 years, with no statistical difference (t te…

The Aging Midfacial Skeleton: Implications for Rejuvenation and Reconstruction Using Implants

Facial plast Surg 2009; 25: 252-259DOI: 10.1055/s-0029-1242037ABSTRACTTraditional theories on facial aging and methods for rejuvenation focus primarily on soft tissues with ptosis as the major mechanism responsible for senescent changes. Anatomic studies demonstrate that there are also many changes to the craniofacial skeleton as patients age. Midface skeletal augmentation, using implants made of porous polyethylene, is a simple and effective method to reverse age-related changes of the facial skeleton in patients with intact occlusion. Skeletal implants correct concave morphology by increasing projection and provide a means to resuspend cheek soft tissues that have descended off a deficient bony platform. Beyond rejuvenation, skeletal implants can be used to restore facial proportions in …
