Includes anatomic description of the fixed and mobile SMAS. Unlike lateral SMAS facelift flap procedures (high or low), the extended deep plane facelift enters the sub-SMAS plane medially at the mobile SMAS giving it a biomechanical advantages when lifting the anterior midface and jowl soft tissue ptosis. Integral to this procedure is release of four key retaining ligaments in the face and neck, the zygomatic cutaneous, masseteric cutaneous, mandibular cutaneous, and cervical retaining ligaments. Once released, the composite deep plane flap is repositioned in a vertical vector to volumize the midface and gonial angle along the jawline. Important anatomic considerations during the deep plane dissection are discussed. In the midface, these include the fixed and mobile SMAS, zygomatic and masseteric cutaneous ligaments, facial fat compartments, and facial nerve. In the neck, focus is on extending the deep plane dissection of the platytsma, releasing the cervical retaining ligaments. This course will also discuss modification in platysma myotomies that improve jawline contour, and re-draping the composite deep plane flap to volumize the midface and gonial angle which atrophy with age, thus improving the cheek and jawline contour.  Data on longevity and efficacy will be presented based upon cohort studies of over 1000 patients.
