Establishment of Safety of Hemostatic Net Application Utilizing Laser-Assisted Fluorescence Angiography With SPY-Q Software Analysis.

BACKGROUND: The hemostatic net, which was initially described as a method to decrease hematoma rates in facelift and necklift procedures, has since increased in practice and applicability. However, despite its demonstrated safety and efficacy, there exists significant skepticism with regard to its necessity; in particular, there is concern that the transcutaneous sutures may restrict dermal perfusion. OBJECTIVES: The goal of this study was to assess flap perfusion, both before and after application of the hemostatic net, to determine if there was an objective decrease in tissue perfusion in relation to application of the hemostatic net, as measured by laser-assisted angiography (LAA). METHODS: Eight patients underwent cervicofacial flap reconstruction of cutaneous malignancy defects, after which a hemostatic net was applied. All patients underwent evaluation with LAA both before and after application of the net. The average relative and absolute perfusion of different zones of the flap were calculated. RESULTS: The average absolute change in relative perfusion was +6.41%, +0.31%, and +3.28% for zones 1, 2, and 3, respectively, after application of the hemostatic net. There was no statistical difference in relative tissue perfusion after application of the net. There were no instances of delayed healing, infections, ischemia, necrosis, or hematoma. One patient developed a seroma after the net was removed. No patients had scarring or residual track marks from the transcutaneous sutures. CONCLUSIONS: With LAA, we were able to objectively demonstrate no significant decrease in tissue perfusion after the application of the hemostatic net.

The Utilization of Poly-l-Lactic Acid as a Safe and Reliable Method for Volume Maintenance After Facelift Surgery With Fat Grafting.

Background: For age-related volume loss, fat grafting is now recognized as an integral adjunctive procedure with facelift surgery. However, when there is continued and unpredicted volume loss postoperatively, the surgeon has limited options for restoring this lost volume. Objectives: Poly-l-lactic acid (PLLA) is a proven biostimulator that creates volumetric enhancement. This study is undertaken to demonstrate that PLLA is a safe and efficacious option for maintenance of post-facelift volume loss. Methods: A retrospective review was conducted to identify all patients who underwent facelift surgery with fat grafting and postoperative PLLA injections from 2010 to 2018 by a single surgeon. Demographic and clinical data were collected and analyzed. Results: This review identified a total of 241 patients who had undergone a facelift with fat grafting and PLLA injections. Of these, 190 patients were treated with PLLA after facelift and fat grafting, while 51 patients received PLLA injections before their operation. We identified 5 common indications for use of PLLA after facelift surgery and fat grafting. These included unexplained early fat graft loss, significant weight loss in the postoperative period, normal aging process, and patients who had a high perioperative lean body mass. Additionally, PLLA was found to be an effective volumizer for site-specific areas that did not undergo fat grafting during the initial operation. There were no complications reported from the PLLA injections related to nodule formation, papules, or granulomas. Conclusions: The high degree of variability in the survival of fat grafts with facelift surgery is an accepted reality. PLLA represents a safe and highly effective solution to restore volume loss in patients who have undergone facelifts with fat grafting.

Optimizing Outcomes in Neck Lift Surgery.

BACKGROUND: In certain patients there is an imbalance between the volume of the anterior neck and the mandibular confines that requires reductional sculpting and repositioning of the hyoid to optimize neck-lifting procedures. OBJECTIVES: A quantitative volumetric analysis of the impact of the management of supraplatysmal and subplatysmal structures of the neck by comparing surgical specimens was performed to determine the impact of reduction on cervical contouring. METHODS: In 152 patients undergoing deep cervicoplasty, the frequency of modification of each surgical maneuver and the amount of supraplatysmal and subplatysmal volume removed was measured by a volume-displacement technique. RESULTS: The mean total volume removed from the supraplatysmal and subplatysmal planes during deep cervicoplasty was 22.3 cm3 with subplatysmal volume representing 73% of the total. Subplatysmal volume was reduced in 152 patients. Deep fat volume was reduced in 96% of patients by a mean of 7 cm3, submandibular gland volume in 76% of patients by a mean of 6.5 cm3, anterior digastric muscle volume in 70% of patients by a mean of 1.8 cm3, perihyoid fascia volume in 32% of patients by a mean of <1 cm3, and mylohyoid volume in 14% of patients by a mean of <1 cm3. The anterior digastric muscles were plicated to reposition the hyoid in 34% of cases. Supraplatysmal fat reduction was 6.3 cm3 in 40% of patients. CONCLUSIONS: The study provides a comprehensive analysis of the impact of volume modification of the central neck during deep cervicoplasty. This objective evaluation of neck volume may help guide clinicians in the surgical planning process and provide a foundation for optimizing cervicofacial rejuvenation techniques.

Neck Deformities in Plastic Surgery.

This article provides facial plastic surgeons with the insight to avoid and address common pitfalls in neck procedures. Many aesthetic issues are created from overtreatment or undertreatment of components of the neck. Using the platysma muscle as the divide, ease of access to superficial anatomy leads to overtreatment problems, whereas difficulty of access to deeper structures leads to undertreatment problems and to overall imbalances. Strategies to accurately assess and treat all structures of the neck proportionally can be used to both avoid and treat any neck aesthetic issues. The advent of minimally invasive techniques has resulted in new complications.
