Use of Micro-focused Ultrasound for Skin Tightening of Mid and Lower Face
imageBackground: The changes in the mid face and lower face are among the most prominent features of the aging process. Intense focused ultrasound, known as the Ulthera System (Ulthera Inc., Mesa, AZ, USA), was designed to correct this process. It employs micro-focused ultrasound to cause discrete focal heating of the dermis and stimulates neocollagenesis and elastin remodeling. Methods: This study enrolled 50 adult patients of Indian ethnicity who opted for correction of mid face and lower face sagging by Ulthera. The subjects were treated using Ulthera 3.0 mm probes which targets deep dermis and 4.5 mm, which targets the superficial muscular aponeurotic system. All patients were evaluated for allergic reactions and side effects like scarring and nerve/muscle dysfunction. Investigators Global Aesthetic Improvement Scales Scores and Patients Global Aesthetic Improvement Scales Scores were used for analysis at 30 days, 60 days, 3 months, 6 months, and 1 year. Photographs were taken for detailed facial evaluation. Patients were asked to fill a self-assessment questionnaire. Results: At the end of 6 months, improvements in mid face and lower face were reported in 93% patients by blinded reviewers and 85% patients found the results to be satisfactory. The same results were maintained at the end of 1 year. Conclusion: Our study showed that substantial results can be achieved in overall aesthetic improvement of sagging of mid face and lower face with this modality using intense focused ultrasound which utilizes delivering of treatment at a single focal depth.
Triple-C SMAS Plication Facelift for Natural Facial Rejuvenation
imageBackground: Various methods are used to reposition the superficial musculoaponeurotic system (SMAS) during facelift procedures. This study presents a novel, radially oriented, layered SMAS plication: the triple-C SMAS plication. This technique utilizes customizable vectors in the pattern of a “C” to plicate the SMAS in 3 layers to lift and tighten the deep structures of the face. Methods: A retrospective review was performed of patients undergoing the triple-C SMAS plication over a 1-year period. Patients with a length of follow-up less than 100 days were excluded from the study. Demographic data, operative data, complication rates, and satisfaction rates were assessed. Results: One hundred ninety-one consecutive patients underwent a triple-C SMAS plication over a 12-month period. One hundred ten patients met inclusion criteria. Average follow-up was 404.5 days. Complications assessed included temporary facial nerve neuropraxia (0.91%), major hematoma (1.82%), minor hematoma (2.73%), seroma (4.54%), great auricular nerve injury (0%), postauricular skin slough >2 cm (1.82%), and infection (0.91%). Two revision procedures were performed (1.82%). Patient satisfaction rate was 96.4%. Conclusions: Traditional SMAS plication techniques involve single-layer, straight-line plications to lift the lower face and neck, limiting their versatility. The triple-C SMAS plication represents a novel technique to safely and effectively elevate the deep structures of the face in a radial pattern to restore a more youthful contour to the malar area, jawline, and neck. This represents a unique strategy for face lifting by which excellent results can be consistently obtained.
Near-circumferential Lower Body Lift: A Review of 40 Outpatient Procedures
imageBackground: Lower body lift surgery has increased in popularity. A circumferential body lift or belt lipectomy is often recommended to treat skin redundancy. A drawback for this procedure is the midline scar bridging the lower back causing elongation of the gluteal cleft. Autoaugmentation methods have not been shown to provide a net increase in buttock volume. Methods: A retrospective study was undertaken among 40 consecutive women and men undergoing near-circumferential outer thigh and buttock lifts, including 21 lower body lifts (with abdominoplasty). All procedures were performed by the author as outpatients, under total intravenous anesthesia, without muscle relaxation and without prone positioning. Most patients (80%) had liposuction. Fourteen patients had simultaneous inner thigh lifts. Buttock fat transfer was used in 13 patients. Most patients had simultaneous cosmetic procedures of the face or breasts. Results: Fourteen patients (35%) experienced complications. One patient developed a deep venous thrombosis, detected by routine ultrasound screening on the day after surgery. Local complications included 3 patients with seromas (8%), 2 wound dehiscences (5%), and 1 infection (3%). Three patients (8%) returned for secondary outer thigh lifts. There were no complications related to fat injections. Conclusions: The near-circumferential lower body lift may be performed in healthy outpatients with attention to safe anesthesia, normothermia, limited blood loss, and operating times <6 hours. A scar across the posterior midline may be avoided. Fat injection safely restores gluteal volume. Secondary surgery may be recommended to treat persistent skin laxity.
Physical and Visual Characteristics of the Neck Predicting Gender Perception
imageBackground: The association between neck characteristics (physical and visual) and the perception of gender is unclear. This association is critical, especially when the perception of the speakers’ gender is of interest, such as in transgender patients. This study was the first to provide basic empirical data on this association among cisgender men and women. Methods: The necks of 30 adult men and women were measured physically and then photographed and evaluated visually by a group of 10 judges. These judges also evaluated voice recordings of the same speakers. Another group of 124 judges rated the visual and auditory masculinity/femininity of the necks and the voices. Results: While most physical measures of the neck were larger for men, neck-length did not significantly differ between genders. A stepwise multiple regression model revealed that the single physical measure that consistently differed between genders was neck-girth (P < 0.0001). The single visual-appearance measure that consistently differed between genders was thyroid-protrusion (P = 0.0003). Neck-girth was the only physical characteristic that significantly correlated with gender differences in voice. Furthermore, the size of the thyroid prominence (ie, Adam’s apple) was not associated with gender differences in voice. Conclusions: Neck characteristics (both physical and visual) are significantly associated with the perception of gender. While larger necks are typically perceived as masculine, neck-length is neither associated with gender nor with the speaker’s voice characteristics. These findings highlight the importance of examining various physical and visual characteristics of the neck, when considering a feminization confirmation procedure for transgender patients.
Veritas in Immediate Implant-based Breast Reconstruction Is Associated with Higher Complications Compared with TiLOOP
imageBackground: Biologic and synthetic meshes are used in immediate implant-based breast reconstruction for coverage of the lower pole of the implant. This study aimed to compare outcomes of Veritas with TiLOOP bra (TiLOOP group [TG]). Methods: Retrospective study of skin- and nipple-sparing mastectomies in patients who underwent an implant-based reconstruction using either Veritas or TiLOOP bra between January 2014 and December 2016 was performed. Results: Thirty-six reconstructions (22 unilateral, 7 bilateral) using the Veritas mesh and 179 breast reconstructions (61 unilateral, 59 bilateral) using TiLOOP bra were identified. The Veritas group (VG) showed a higher rate of postoperative complications compared with the TG (VG = 54% versus TG = 14%, P < 0.01%), including higher rates of seroma, nonintegration of mesh (VG = 51.4% versus TG = 1.6%, P < 0.01), implant rotation (VG = 16.2% versus TG = 1.6%, P < 0.01), infection (VG = 18.9% versus TG = 2.1%, P < 0.01), and wound breakdown (VG = 10.8% versus TG = 0.5%, P < 0.01). The VG also had a higher rate of major interventions (VG = 35.1% versus TG = 7.8%, P < 0.01) and minor interventions (VG = 18.9% versus TG = 2.2%, P < 0.01) compared with TG, including a higher rate of implant loss and unplanned return to theater. Conclusions: Veritas mesh was associated with a significantly higher rate of postoperative complications compared with TiLOOP bra. Our data strongly question the safety profile of Veritas in implant-based breast reconstruction. Further studies in this area are warranted.
Breast Reconstruction Utilizing Buried Dermato-cutaneous Skin Flaps and Immediate Adipocyte Transfer: A Minimally Invasive Autologous Breast Reconstruction Technique
imageBackground: Autologous breast reconstruction historically required flaps that were invasive, required prolonged operative times and recoveries, and resulted in varying degrees of donor site morbidity. We present our early results with a minimally invasive completely autologous breast reconstruction technique utilizing buried dermato-cutaneous (DMC) flaps and immediate fat grafting. A 25-patient, 43-breast consecutive case series is presented. Methods: Select patients desiring autologous breast reconstruction who had sufficient breast ptosis and fat donor tissue were offered breast reconstruction with buried folded over DMC flaps with adipocyte transfer (DCAT). A Wise pattern mastectomy was performed, and fat was transferred into an inferiorly based, buried and folded DMC flap. Fat was also immediately grafted into the pectoralis, subpectoral space, and below pectoralis and serratus fascia. Most patients underwent additional fat grafting at 3-month intervals to complete the reconstruction. Results: Twenty-five consecutive patients (43 breasts) underwent the DCAT procedure with 18 (42%) free nipple grafts. Eight patients (8 breasts) had prior breast radiation, and 2 patients (2 breasts) required postmastectomy radiation. Average fat grafted at initial mastectomy was 70 mL per breast (range 50–103 mL). Nineteen patients (76%) underwent additional outpatient fat grafting. Two additional outpatient fat graft sessions (range 0–3) at 3-month intervals completed the reconstruction. Average fat grafted at the second stage was 217 mL (range 50–320 mL). Average follow-up was 20 months from DCAT and 12 months from last fat graft. Conclusion: The DCAT procedure appears to provide a minimally invasive, autologous breast reconstruction alternative in select patients.
Implant-based Breast Reconstruction Outcomes Comparing Freeze-dried Aseptic Alloderm and Sterile Ready-to-use Alloderm
imageBackground: The use of acellular dermal matrix has revolutionized implant-based breast reconstruction in the 21st century. There have been a number of different dermal matrices introduced to clinical use and their equivalence has been debated. The purpose of this study is to examine a sequential series of acellular dermal matrix assisted implant-based breast reconstructions by a single surgeon and to compare the outcomes between a freeze-dried (FD) Alloderm cohort and a sterile ready to use Alloderm cohort. Methods: After institutional review board approval, all consecutive implant-based breast reconstructions of a single surgeon (D.S.W.) from January 2009 to June 2016 were examined. Two hundred thirty-six patients received either FD Alloderm in the first 151 breasts reconstructed or sterile ready-to-use Alloderm in the last 227 breasts. Results: The FD Alloderm patients had more tissue expander reconstructions performed and were all subpectoral placement. The ready-to-use Alloderm patients had more direct-to-implant procedures and some prepectoral placements. The complication rates were similar for seroma, hematoma, skin necrosis, and dehiscence. There were more infections, implant losses, and unexpected reoperations in the FD Alloderm group. Conclusion: The rate of infection, explantation, and unexpected reoperation was lower in the sterile ready-to-use Alloderm group versus the FD Alloderm group.
Short-term Safety of Augmentation Mammaplasty Using the BellaGel Implants in Korean Women
imageBackground: Asian women are stereotypically characterized by a slim body, smaller breasts and areolae, and larger nipples when compared with White women. They would therefore be vulnerable to displacement of a breast implant if they receive larger implants. They are also prone to hypertrophic and prolonged hyperemic scars. Surgeons should therefore be aware of Asian women’s breast anatomy, healing tendency, and preferences. We conducted this multicenter, retrospective study to assess the short-term safety of the BellaGel implants in Korean women. Methods: We evaluated a total of 637 women (n = 637; 1,274 breasts) for incidences of postoperative complications and the cumulative Kaplan–Meier complication-free survival. Results: Overall, there were 12 cases (1.9%) of postoperative complications; these include 6 cases (0.9%) of hematoma, 2 cases (0.3%) of infection, and 4 cases (0.6%) of seroma. Moreover, there was no significant difference in the cumulative complication-free survival at 120 weeks between the 4 types of the BellaGel implants (χ2 = 2.289, P = 0.513). Conclusion: In conclusion, we describe the short-term safety of augmentation mammaplasty using the BellaGel implants in Korean women. But further prospective, large-scale, multicenter studies with a long period of follow-up are warranted to establish our results.
The Impact of Device Innovation on Clinical Outcomes in Expander-based Breast Reconstruction
imageBackground: Staged expander-based breast reconstruction represents the most common reconstructive modality in the United States. The introduction of a novel tissue expander with an integrated drain (Sientra AlloX2) holds promise to further improve clinical outcomes. Methods: Patients who underwent immediate expander-based pre-pectoral breast reconstruction were identified. Two cohorts were created, that is, patients who underwent placement of a conventional tissue expander [133MX (Allergan)] (Group 1) versus AlloX2 (Sientra) (Group 2). The study endpoint was successful completion of expansion with the objective being to investigate differences in outcome following expander placement. Results: Fifty-eight patients underwent 99 breast reconstructions [Group 1: N = 24 (40 breasts) versus Group 2: N = 34 (59 breast)]. No differences were noted for age (P = 0.586), BMI (P = 0.109), history of radiation (P = 0.377), adjuvant radiotherapy (P = 1.00), and overall complication rate (P = 0.141). A significantly longer time to drain removal was noted in Group 1 (P < 0.001). All patients with postoperative infection in Group 1 required surgical treatment versus successful washout of the peri-prosthetic space via the AlloX2 drain port in 3 of 5 patients in Group 2 (P = 0.196). Furthermore, both cases of seroma in Group 1 required image-guided drainage versus in-office drainage via the AlloX2 drain port in 1 patient in Group 2 (P =0.333). Conclusion: The unique feature of the AlloX2 provides surgeons easy access to the peri-prosthetic space without altering any of the other characteristics of a tissue expander. This resulted in a reduced time to drain removal and facilitated management of postoperative seroma and infection.
Death by Implants: Critical Analysis of the FDA-MAUDE Database on Breast Implant-related Mortality
imageIntroduction: Since the 1992 moratorium by the Food and Drug Administration (FDA), the debate on the association of breast implants with systemic illnesses has been ongoing. Breast implant-associated anaplastic large cell lymphoma has also raised significant safety concerns in recent years. Methods: A systematic search of the Manufacturer and User Facility Device Experience (MAUDE) database was performed to identify all cases of breast implant-associated deaths reported to the FDA. Results: The search identified 50 reported cases of apparent implant-related mortality; breast implant-associated anaplastic large cell lymphoma comprised the majority of fatal outcomes (n = 21, 42%), followed by lymphoma (n = 4, 8%), breast cancer (n = 3, 6%), pancreatic cancer (n = 2, 4%), implant rupture (n = 2, 4%), and postoperative infections (n = 2, 4%). Single cases (n = 1, 2% each) of leukemia, small bowel cancer, lung disease, pneumonia, autoimmune and joint disease, amyotrophic lateral sclerosis, liver failure, and sudden death, and 2 cases (4%) of newborn deaths, to mothers with breast implants, were also identified. A literature review demonstrated that 54% of alleged implant-related deaths were not truly associated with breast implant use: the majority of these reports (82%) originated from the public and third-party sources, rather than evidence-based reports by health-care professionals and journal articles. Conclusions: Although there exists a need for more comprehensive reporting in federal databases, the information available should be considered for a more complete understanding of implant-associated adverse outcomes. With only 46% of FDA-reported implant-related deaths demonstrated to be truly associated with breast implant use, there exists a need for public awareness and education on breast implant safety.
