High-Definition Liposculpture 18-Year Evolution: Patient Safety and Aesthetic Outcomes.

BACKGROUND: High-definition liposculpture (HDL) emerged as an innovative surgical technique that allowed plastic surgeons to achieve improved aesthetic results with a natural and athletic appearance using minimal incisions and with imperceptible scarring. Its targets are high aesthetic standards and patient safety. PURPOSE: This article summarizes the evolution of HDL by explaining upgrades to the original technique and comparing the complication rates among them. METHODS: The authors retrospectively reviewed records from four private medical centers (Evolution Medical Center, Santa Barbara Medical Center, and Dhara Clinic in Bogota and FOSCAL in Bucaramanga, Colombia) of patients who underwent HDL performed by the senior author (A.E.H) over an 18-year period (2002 through 2019). Patients were classified into three groups: suction-assisted lipoplasty (period 1), vibration amplification of sound energy at resonance-assisted HDL (period 2), and dynamic definition liposculpture (period 3). RESULTS: The authors established a cohort of 5052 patients (4300 women and 752 men): 923 in period 1, 1272 in period 2, and 2857 in period 3. The most common complications included seroma, bruising, hematoma, acute anemia, hyperchromia, wrinkled skin, wound dehiscence, and local infections. CONCLUSIONS: HDL and dynamic-definition liposculpture procedures are safe and reproducible techniques to achieve an athletic and natural body contour. Complication rates, especially those related to bleeding, decreased as the technique evolved. These procedures are aimed toward patient safety to provide higher aesthetic outcomes using extensive medical, anatomic, artistic, and technological knowledge.

H-Wing Neoumbilicoplasty: A New Technique for Advanced Abdominoplasty and Umbilical Zones by Gender.

BACKGROUND: Multiple umbilicoplasty techniques have been described, even more after the advent of full tummy tuck procedures and the neoumbilicoplasty (X-shaped incision) described by the authors in a previous report. The authors decided to upgrade the technique (H-wing incision) because the former procedure is associated with relatively common complications. The authors report a case series of an upgraded technique for neoumbilicoplasty (H-wing technique), comparing its outcomes with their previous standard procedure (X-shaped incision). METHODS: The authors reviewed their records for neoumbilicoplasties performed between January of 2014 and December of 2019. The authors divided the procedures according to the surgical technique and performed a detailed analysis regarding timing, complications, uses, and quality standards according to patients' opinion through a nonstandardized survey. RESULTS: A total of 407 procedures were distributed between two techniques: X-shaped incision, 179 procedures; and H-wing technique, 228 procedures. The former was performed from January of 2014 to October of 2016 and the latter from September of 2016 to December of 2019. High satisfaction indexes were found for both procedures; however, fewer complications were seen in the H-wing group. The X-shaped incision is thought to generate a greater force of tension over the flaps compared to that from the H-wing technique, which consequently increased the risk of flap necrosis and flattening. CONCLUSIONS: The H-wing technique for neoumbilicoplasty decreases the risk of postoperative complications such as dehiscence, skin necrosis, and navel flattening, and maintains high aesthetic standards and satisfaction indexes among patients. The technique can be used after either lipoabdominoplasty or secondary procedures.

Decision-Making Algorithm for Advanced Excisional Body Contouring: Dynamic Definition Solutions for Skin Laxity.

BACKGROUND: Excisional body contour surgery is the cornerstone treatment for skin laxity. Decision-making can be challenging when selecting the procedure. Dynamic definition liposculpture allows the surgeon to carve the underlying anatomy and provide more natural results, in which umbilical shape and position play a crucial role. The authors describe their experience using a decision-making algorithm as a tool to ease surgical planning for advanced excisional body contouring. METHODS: Following the algorithm designed by the senior author regarding excisional body contouring procedures, the authors searched their database for patients who were classified according to skin laxity and navel location to undergo one of the following procedures: mixed technologies plus umbilical mobilization, mixed technologies plus sliding mini-abdominoplasty, mini-tummy tuck with muscular plication, full abdominoplasty, reverse bridge abdominoplasty, or reverse full abdominoplasty. RESULTS: A total of 563 women were consecutively operated on from February of 2014 to January of 2020. The six-procedure model algorithm helped the authors achieve very good results with low complication rates in patients with some grade of abdominal skin laxity. Most complications were reported as minor (9.6 percent). Major complications (3.9 percent) included three localized infections, four abnormal skin retractions, two cases of skin flap necrosis, and 13 cases of postoperative anemia. CONCLUSIONS: This algorithm helped the authors choose the best excisional technique based on patients' anatomical features by following skin geometry to enhance aesthetic outcomes. Further studies are needed to support the algorithm validation and aesthetic outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Use of Tranexamic Acid in Liposculpture: A Double-Blind, Multicenter, Randomized Clinical Trial.

BACKGROUND: Intraoperative hemostasis should be performed with great caution because bleeding is a huge enemy of patient safety during surgery. Tranexamic acid is a lysine synthetic derivate that inhibits fibrinolysis and diminishes the bleeding by blocking the five lysine-binding sites for plasminogen. The authors compare the efficacy of tranexamic acid versus placebo as a hemostatic agent in liposculpture procedures. METHODS: The authors conducted a multicenter, double-blind, randomized, controlled clinical trial in patients who were scheduled for liposculpture in three plastic surgery centers (Colombia and Mexico) between January of 2019 and February of 2020. One hundred forty-one patients were randomly assigned into three groups: intravenous (1 g of tranexamic acid), subcutaneous (1 g of tranexamic acid), and placebo (normal saline). Forty-seven patients were assigned to each group. There were 30 male patients and 111 female patients. The main outcome was to evaluate the amount of postoperative bleeding between groups. The primary outcome was measured by the hemoglobin point loss at day 1 (preoperative hemoglobin minus hemoglobin at day 1 postoperatively) and the hemoglobin (in milligrams per deciliter) point loss at day 5 (preoperative hemoglobin minus hemoglobin at day 5 postoperatively). RESULTS: The authors found the intravenous intervention group to have a greater hemoglobin level than the other two groups on both the first postoperative day ( p = 0.0001) and the fifth postoperative day ( p = 0.001). There were no statistical differences in hemoglobin values between the placebo and the subcutaneous intervention groups. CONCLUSION: Intravenous tranexamic acid is a good therapeutic choice to implement on liposculpture procedures to decrease postoperative bleeding. CLINICAL RELEVANCE STATEMENT: The preoperative use of intravenous tranexamic acid not only decreases the bleeding rate after liposuction procedures, but also allows greater lipoaspirate volumes when performing high-definition liposculpture. Further studies are required to support the effectiveness of tranexamic acid within the infiltration solution. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.

TULUA Male High-Definition Abdominoplasty.

BACKGROUND: Abdominoplasty is a surgical technique for body contouring that has been shown to improve the patient's quality of life. It has become more common among male patients, so clear differences between procedures for men and women have to be stated. The authors present their experience with high-definition lipoabdominoplasty with transverse plication in men. METHODS: Records of male patients undergoing transverse plication full abdominoplasty in addition to high-definition liposculpture were analyzed. A total of 24 consecutive cases were found between January of 2017 and June of 2019. Patient ages ranged from 24 to 60 years. Patients aged 18 years or younger were excluded. Body mass index ranged from 25 to 33 kg/m2. Photographic records were taken before and during follow-up at 2 days and 1, 3, 6, and 12 months after surgery. RESULTS: Male TULUA (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar) with high-definition lipoabdominoplasty was successfully achieved in 24 cases. No major complications were reported. Six minor complications were reported (25 percent). Rectus abdominis diastases are less common in men compared to women, as pregnancy is the most determining factor in its development. Fat distribution is also a key difference when performing lipoabdominoplasty for the male or the female patient. The authors recommend a transverse plication of the abdominal wall, instead of a vertical one, as flap viability is preserved and enhanced muscular definition can be accomplished. CONCLUSIONS: Combining transverse plication with high-definition lipoabdominoplasty (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar plus high-definition lipoabdominoplasty) is a safe and reproducible technique for the male patient. It offers higher aesthetic results in line with modern beauty ideals. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
