Periorbital Rejuvenation for Asians.

A primary concern in facial aesthetics is the rejuvenation of periorbital areas through soft tissue recontouring, skin texture improvement, and harmoniousness with souring anatomic tissues. Currently, the ease of harvesting, abundance in volume, and lack of immune rejection make autologous fat transplantation a disruptive strategy in aesthetic medicine. The evolution and improvements made by myriad surgeons have contributed to the popularity of periorbital rejuvenation and have highlighted its indispensability in Asian patients. Lin and colleagues have advocated the technique of microautologous fat transplantation since 2007 for facial recontouring and rejuvenation. This article illustrates more in-depth technical details and innovative concepts for the improvement of the periorbita.

Three Simple Steps for Refining Transcutaneous Lower Blepharoplasty for Aging Eyelids: The Indispensability of Micro-Autologous Fat Transplantation.

BACKGROUND: Lower blepharoplasty has been used for rejuvenating lower eyelids, and diverse modifications have been used to treat conjunct deformities at the tear trough/lid-cheek junction. Strategies for recontouring prominent tear trough/lid-cheek junctions, including orbital fat manipulation, have been reported with good results in the literature. Micro-autologous fat transplantation (MAFT) is a previously unevaluated, potentially advantageous approach to blending the prominent tear trough/lid-cheek junction. OBJECTIVES: We determined the long-term results after 3-step transcutaneous lower blepharoplasty with MAFT for patients with aging eyelids and prominent tear trough/lid-cheek junctions. METHODS: We evaluated 205 patients with aging lower eyelids who underwent transcutaneous lower blepharoplasty with MAFT between October 2010 and September 2016. The 3-step procedure involved a subciliary elliptical skin excision, resection of 3 orbital fat compartments, and MAFT for the tear trough/lid-cheek junction employing a MAFT-GUN under intravenous anesthesia. RESULTS: The mean patient age was 52 years (range, 34-78 years). The mean operating time was 61 minutes. The mean fat volumes delivered to the tear trough/lid-cheek junctions were 2.80 mL and 2.76 mL for the left and right sides, respectively. The average weights of the 3 resected orbital fat compartments were 0.58 g for the left side and 0.56 g for the right side. Patients showed significant improvement and maintenance at an average follow-up of 60.2 months (range, 18-90 months). CONCLUSIONS: Three-step transcutaneous lower blepharoplasty with MAFT is an effective, reliable, and promising method with high patient satisfaction and minimal risk of complications. Long-term results demonstrated its utility for aging lower eyelid treatment.

Micro-Autologous Fat Transplantation for Treating a Gummy Smile.

BACKGROUND: A gummy smile is treated using many techniques, including botulinum toxin injection and various surgical interventions. Micro-autologous fat transplantation (MAFT) is a potentially advantageous alternative approach that has not been previously evaluated. OBJECTIVES: This study sought to determine the long-term results of MAFT in patients with a gummy smile. METHODS: Seven patients with gummy smiles were evaluated for MAFT treatment between October 2015 and April 2017. Centrifuged purified fat was micro-transplanted into the nasolabial groove, ergotrid, and upper lip areas using the MAFT-GUN while the patients were under total intravenous anesthesia. RESULTS: The mean age of the 7 patients was 31 years (range, 23-40 years). The mean operating time for MAFT was 52 minutes (range, 40-72 minutes), and the mean volume of fat delivered to the nasolabial groove, ergotrid, and upper lip was 16.1 mL. The mean decreases of gingival display in the right canine incisor, left canine incisor, right canine, and left canine teeth were 4.9, 4.6, 3.8, and 4.4 mm, respectively. The smiles of the 7 patients showed significant improvement at an average follow-up time of 12.9 months. CONCLUSIONS: Gummy smile treatment using MAFT is an effective, reliable, and relatively simple method, with high patient satisfaction and minimal risk of complications.

Long-Term Outcome of Microautologous Fat Transplantation to Correct Temporal Depression.

OBJECTIVE: Sunken temporal fossa appears oftentimes in Asians and resembles bad fortune that people wish to change. Numerous techniques and materials have been applied clinically for augmenting the sunken temporal fossa with variable results. The microautologous fat transplantation (MAFT) technique proposed by Lin et al in 2006 has demonstrated favorable results in facial rejuvenation. In the present study, the authors applied the MAFT technique with an innovative instrument in sunken temporal fossa and reported its results. METHODS: Microautologous fat transplantation was performed on 208 patients during the 4-year period starting in January 2010. Fat was harvested by liposuction, processed and refined by centrifugation at 1200 g for 3 minutes. Then purified fat was microtransplanted to the temporal fossa with the assistance of an instrument, MAFT-Gun. The patients were followed up regularly and photographs were taken for comparison. RESULTS: On average, the MAFT procedure took 48 minutes to complete. The average delivered fat was 6.8 ±â€Š0.2 mL/6.5 ±â€Š0.3 mL for the right/left side. The average follow-up period was 18 months. No complication including skin necrosis, vascular compromise, nodulation, fibrosis, and asymmetry was noted. The patient-rated satisfaction 5-point Likert scale demonstrated that 81.3% of all patients had favorable results (38.5% very satisfied and 42.8% satisfied). CONCLUSIONS: The concept and technique of MAFT along with the micro- and precise controlling instrument enabled surgeons to perform fat grafting accurately and consistently. In comparison with other strategies for volume restoration, the MAFT procedure demonstrated the patients' high satisfaction with the long-term results. Therefore, the potential of MAFT as an alternative strategy in sunken temporal fossa in Asians was emphasized.

Microautologous Fat Transplantation for Primary Augmentation Rhinoplasty: Long-Term Monitoring of 198 Asian Patients.

BACKGROUND: Numerous techniques and materials are available for increasing the dorsal height and length of the nose. Microautologous fat transplantation (MAFT) may be an appropriate strategy for augmentation rhinoplasty. OBJECTIVES: The authors sought to determine the long-term results of MAFT with the so-called one-third maneuver in Asian patients who underwent augmentation rhinoplasty. METHODS: A total of 198 patients who underwent primary augmentation rhinoplasty with MAFT were evaluated in a retrospective study. Fat was harvested by liposuction and was processed and refined by centrifugation. Minute parcels of purified fat were transplanted to the nasal dorsum with a MAFT-Gun. Patient satisfaction was scored with a 5-point Likert scale, and aesthetic outcomes were validated with pre- and postoperative photographs. RESULTS: The mean age of the patients was 45.5 years. The mean operating time for MAFT was 25 minutes, and patients underwent 1-3 MAFT sessions. The mean volume of fat delivered per session was 3.4 mL (range, 2.0-5.5 mL). Patients received follow-up for an average of 19 months (range, 6-42 months). Overall, 125 of 198 patients (63.1%) indicated that they were satisfied with the results of 1-3 sessions of MAFT. There were no major complications. CONCLUSIONS: The results of this study support MAFT as an appropriate fat-transfer strategy for Asian patients undergoing primary augmentation rhinoplasty. LEVEL OF EVIDENCE 4: Therapeutic.

Fat Grafting for Recontouring Sunken Upper Eyelids With Multiple Folds in Asians-Novel Mechanism for Neoformation of Double Eyelid Crease.

BACKGROUND: This study reviewed the mini invasive technique, microautologous fat transplantation (MAFT), as a strategy in simultaneously treating sunken upper eyelids with multiple folds and recreating a double eyelid crease in Asian people. METHODS: The MAFT was performed with the assistance of a patented medical device, the MAFT-GUN, on 34 patients who had sunken upper eyelids and multiple folds. Each delivered fat parcel was accurately and consistently maintained at 1/240 mL during placement. Follow-up was regularly performed with photography for comparison. RESULTS: Fifty-eight sunken upper eyelids with multiple folds were reconstructed. In addition to the ameliorative recontouring of hollowness, a natural eyelid crease was created postoperatively. Temporary swelling and bruising were noted several days after surgery without morbidities, such as fibrosis or nodulation. All of the patients were satisfied with the 1-time MAFT procedure. CONCLUSIONS: Fat grafting for sunken upper eyelids with multiple folds has been reported in the literature. However, temporal effects and complications, such as nodulation and irregularity, have often occurred. A new method, MAFT, demonstrated its reliability as a modality for sunken upper eyelids with multiple folds in Asians. Moreover, MAFT might serve as an alternative for neoformation of double eyelids in these candidates.

Application of microautologous fat transplantation in the correction of sunken upper eyelid.

BACKGROUND: Although fat grafting has been clinically applied by surgeons in esthetic and reconstructive surgery, it has widely evolved in processes such as harvesting, processing, and placement of fat, using the fat-grafting procedure, which dates back over 100 years. Surgeons frequently use fat grafting to recontour, augment, or fill soft-tissue defects, facial wrinkles, or skin problems such as depressions or scars. However, fat grafting has not been thoroughly understood and has not been conclusively standardized to ensure superior clinical results. METHODS: This study was intended to determine the role of microautologous fat transplantation (MAFT) under evidence-based medicine, particularly in accurate delivery of small fat parcels. The research method involved the conceptualization of MAFT and the development of an innovative surgical instrument for fat placement. Clinically, 168 patients with sunken upper eyelids with multiple folds underwent this procedure. RESULTS: The major findings suggested that MAFT exhibits promising clinical results and offers a superior guideline for fat placement. Details of the technique and theoretical implications are also discussed. CONCLUSIONS: The therapeutic effects of MAFT and the long-term clinical results of patients with sunken upper eyelids with multiple folds indicated satisfactory outcomes. Based on the results, MAFT offers an alternative option to surgeons for performing fat grafting and provides a more favorable option for the benefit and welfare of patients by reducing the potential complications.
