Aesthetic Surgery of the Facial Skeleton

Embryology and development of the facial skeleton

Key points • The embryological components of the facial skeleton are derived from the three divisions of the skull: the desmocranium, the chondrocranium and the viscerocranium. • The ectomeninx has chondrogenic and osteogenic properties which translate into intramembranous bone that…

Biology of fat grafting

• Centrifuged fat has three layers: (1) the upper supernatant, containing lipid; (2) the middle stromal vascular fraction, containing adipose-derived stem cells, stromal cells, vascular cells, and mural cells; and (3) the lower layer, containing blood, local anesthetic, and tissue…

Aging of the facial skeleton

• Visible changes in the aging face (such as jowls, sagging, crow’s feet) are, in part, due to thinning skin that has lost its intrinsic elasticity and nonuniform loss of subcutaneous fat. • The bony skeletal provides the framework on…

Alloplastic and natural materials used as implants

Key points • The success of any implant depends not only on minimizing the inflammatory reaction of the material but also on the prosthetic porosity and stress at the tissue–implant interface. • The porosity of an implant will dictate whether…

Biology of bone and cartilage grafting

• Autologous bone and cartilage grafts remain important tissue sources for surgery of the facial skeleton due to their biocompatibility and long-term success rates. • The revascularization of autologous grafts reduces long-term complications because the graft ultimately establishes a blood…

Photographic advances in facial imaging

• Photography is an essential tool to objectively document patient conditions, evaluate physical deformities, plan treatment approaches, and assess surgical outcomes. • In plastic surgery, clinical photography accomplishes two goals primarily: first, documentation of preoperative conditions and postoperative surgical results,…

Radiologic advances in facial imaging

Key points • The deleterious effects of ionizing radiation are cumulative, necessitating the judicious use of ionizing radiation. • Cone beam CT (CBCT) allows for image capture that displays excellent spatial resolution (image detail) of hard tissue at a relatively…
