Silicone implant for facial plastic surgery

Abstract

The facial implant is made of silicone and has a grid of horizontal and vertical grooves on a concave bone-facing rear surface. The grid pattern of grooves imparts flexibility to the implant to facilitate implantation. In addition, the grooves provide for ingrowth of tissue as well as providing reference marks to facilitate implantation of a pair of mirror-image facial implants in a symmetrical manner. The groove depth may be in a range of from 0.5 to 1 millimeter and may also be of variable depth relative to the cross-sectional thickness of the body.

Plastic surgery implant

Abstract

An improved implant for the mid-facial or submalar region of a patient's face. The implant is relatively thin with a teardrop-shaped profile. It has a relatively broad head which is adapted to fit in the canine fossa of the maxillary bone, and a tapered, relatively narrow tail which extends laterally under the zygomatic eminence. The implant is anatomically correct to create the appearance of soft tissue restoration without distorting the normal facial bone structure. In addition, it softens prominent nasolabial folds, and provides a more youthful looking fullness to the cheeks by repositioning and augmenting soft tissue which has lost the underlying support of an atrophied fat pad of the cheeks.
