Platelet-rich plasma has been increasingly used for facial rejuvenation in conjunction with other modalities such as microneedling or on its own. Nanofat grafting to the face has also been utilized for skin quality improvements. Our group previously described the novel combined Platelet Hybridized Adipose Transplant (PHAT) technique for hair restoration. In this series, we describe our experience with the PHAT technique for lip and facial rejuvenation to improve the quality of facial skin and superficial musculoaponeurotic system, and enhancing surgical results., Competing Interests: None declared., (Thieme.

The exact relationship between the jowl and the mandibular ligament and causes for jowling remain unclear in the literature. The anatomic basis for the jowl is multifactorial and disparities in descriptions of the mandibular ligament and prejowl sulcus have resulted in variations in its management. The aim of this paper was to clarify the anatomy and aging around the prejowl sulcus and the mandibular ligament and review our experience with its management in facial rejuvenation. We performed a retrospective blinded review of patients in a high-volume private practice comparing patients who underwent mandibular ligament release in a subdermal plane during facelift with those who solely underwent fat grafting of the prejowl sulcus with facelift. Blinded surgeons graded 25 patients who had undergone mandibular ligament release and 25 patients who did not. Patient photographs were scored on a 1 to 4 graded scale of correction on the degree of jowling and prejowl sulcus depth and color. We also performed a literature review to describe the anatomy of the mandibular ligament and its implications for jowls, and techniques to address it in facial rejuvenation. Patients who had fat grafting with minimal or no release of the skin around the prejowl sulcus or mandibular ligament had a greater degree of correction of their jowls in their postoperative photographs than those who had a mandibular ligament release without fat grafting (P = .046). Adverse sequelae were also lower in the group with less skin dissection around the mandibular ligament. Our findings support the theory that the appearance of tethering and depression in the prejowl sulcus is more likely the cause of atrophy in the subdermal soft tissues than a consequence of ligamentous contracture. Volumetric replenishment with fat grafting provides a more direct solution to the cause of the issue, providing more universal improvements with less risk. Surgeons should consider volumetric fat grafting with or without subsequent subdermal release if needed., (© The Author(s) 2024.

Background: The vector of aging and consequently the vector of lift in rhytidectomy has aided surgeons in improving movement of tissues during facial rejuvenation procedures., Objectives: The goal was to analyze the vector of lift in patients undergoing primary and revisional facelift to achieve proper vectorial lifting., Methods: Patients undergoing deep-plane facelift surgery were included for analysis. Intraoperative photographs and measurements were taken of the skin, superficial musculoaponeurotic system (SMAS), and platysmal suture suspension with mastoid crevasse inset. Measurements were compared between patients who were undergoing primary vs secondary surgery, site of lift, age, and gender., Results: Seventy-one patients (90% female, mean age 57.8) with a total of 142 hemifaces were analyzed, 57 (73%) of which were primary and 14 (27%) secondary facelifts. The average vector of SMAS lifting was 70.8°. Females had a more vertical vector than males (71.3° vs 65.4°; P < .01). The average vectors of platysmal and skin lift were 87.0° and 58.2°, respectively. There was intrapatient difference between hemifaces. Despite there being more intersuture disparity in secondary cases than primary cases (16.9° vs 4.5°; P < .05), the mean vector of lifting was similar between them., Conclusions: Proper release of the deep plane helps determine the appropriate vectors of lift, without relying on guidelines based on population averages. Each patient presents with a unique vector required to correct their descent. This technique provides an optimal result by directly suspending against the vectors of greatest descent., (© The Author(s) 2024.

The fundamental goal of modern face and neck lifting is to enhance and restore a more youthful facial appearance by addressing soft tissue descent. There are variations in described facelift technique including superficial musculoaponeurotic system (SMAS) flaps, composite flaps, deep plane, skin flaps, and subperiosteal facelifts, among others. The term "deep plane rhytidectomy" was originally described by Hamra. This term has since been linked with facelift surgery with recent advances including incision placement, treatments of SMAS–platysma complex, and mastoid crevasse among others. In the lead authors' experience, using deep plane techniques have demonstrated superior facial surgical rejuvenation results with less dependence on ancillary measures such as fat grafting or implantation for midface volumization. In order to successfully perform any face or neck lift, it is key to understand the relationship of the skin, the fat compartments, and the ligamentous attachments. This chapter details the anatomy of the deep plane of the face and neck and explains some nuances as it relates to surgical lifting. We also describe recent anatomical revelations of the mandibular ligament and its management in deep plane face lifting. In this chapter, given this opportunity to share personal experiences and preferences, the authors hope to describe relevant anatomy for the deep plane and provide some clarity on the merits of deep plane face and neck lift technique.
