Plastic Surgery Key

• Preoperative evaluation must include assessment of nasal function as well as aesthetic goals. • Each approach should be individualized to the patient. Surgical planning must take into consideration form,…

Key points • Skeletal augmentation and soft tissue augmentation can be complementary but are not interchangeable. • Patients with deficient infraorbital rim projection can be predisposed to lower lid malposition…

Key points • As the aesthetic impact of orthognathic surgery is increasingly appreciated, occlusal plane rotation may be used by the surgeon to optimize facial balance. This approach requires bimaxillary…

Key points • The advantage of using CBCT is the accurate visualization of the root angulations. • Initial records using CBCT technology and intraoral scans of the dentitions can be…

Key points • Cephalometric analysis is performed in three-dimensions to allow the surgeon and the orthodontist to address asymmetry in all three planes. • The time-consuming laboratory process of facebow…

• Skeletal contouring can add convexity to the profile and narrow the face from the frontal view. • Procedures on the zygoma, mandible, and chin are usually combined to obtain…

Key points • The overall facial arc should have a slight convexity, with the projection greatest at the subnasale. • Women typically prefer a more convex face, which is more…

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…

Key points • To simplify diagnosis and corrective surgical planning the mandible may be considered in: a genial component, a ramus-and-corpus component, and a dentoalveolar component. • The chin has…

• Orthognathic surgery should achieve a functional occlusion while optimizing facial form. • Aesthetic facial analysis takes priority over cephalometric norms when developing the treatment plan. • Treatment plans should…
