Aesthetic Plast Surg 2025; 49:1130-1138. [PMID: 39658665 DOI: 10.1007/s00266-024-04557-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2024] [Accepted: 11/11/2024] [Indexed: 12/12/2024]
Abstract
BACKGROUND Stromal vascular fraction (SVF) grafting is an effective method to correct tear trough deformity. Nevertheless, the quantitative data of satisfactory rate and complications of SVF compared with normal autologous fat graft (AFG) remain unemployed. The aim of this meta-analysis was to synthesize the current quantitative data on satisfactory rate and complications of tear trough deformity correction with SVF and normal AFG. METHODS A comprehensive literature search was performed in PubMed, Web of Science, and the Cochrane library. All studies evaluating AFG or SVF in the treatment of tear through deformity were included. Then, data were extracted and analyzed using single-arm meta-analysis. The satisfactory rates and complication rates of different techniques were compared. A subgroup analysis was performed according to the specific AFG techniques used. RESULTS A total of 20 literatures comprising 2372 participants were included. Five studied SVF and 15 studied other AFGs. The pooled satisfaction rate of AFG was 94.9% (95% CI 92.2-97.7%, I2 = 65%). A total of 154 cases reported complications. Most common complications were skin winkle 26 cases (16.88%), fat under-correction 24 cases (15.58%) and subcutaneous induration 18 cases (11.69%) (Table 2). The pooled complication rate of AFG was 10.1% (95% CI 4.6-15.6%, I2 = 92%). The pooled complication rate of SVF was 1.5% (95% CI 0-15.6%, I2 = 0%). CONCLUSION Satisfaction rates for both normal AFG and SVF were generally high, with mostly minor complications observed. The incidence of complications with SVF was lower than with normal AFG, and severe complications were rare.

Abstract
BACKGROUND Autologous fat has the advantages of regeneration, rejuvenation, homology, and support. There are currently no reports indicating that injecting autologous fat enhances the fullness of the lower-lid pretarsal roll. OBJECTIVES In this retrospective, non-randomized study, the effects of injecting autologous fat to cosmetically enlarge the lower-lid pretarsal roll were evaluated by comparison of preoperative and postoperative photographs and patient satisfaction during the follow-up. METHODS First, fat tissues were manually sucked with a 20-ml syringe connected to a 2.5-mm three-hole liposuction cannula. The treated fat tissues were transferred to a 10-ml syringe and centrifuged at 2000 rpm for 2 min, and then the fibrous tissues were manually removed. Finally, autologous fat was injected using a 1-ml syringe linked to a sharp needle. RESULTS Forty-seven patients who underwent surgery between 2018 and 2021 were retrospectively evaluated. Only three patients showed obvious asymmetry or uneven outlines after surgery and underwent a second fat injection. During recovery, bruising and minor contouring irregularities obviously improved after 1 or 2 weeks. Eight patients, who had severe bruising, were able to make a full recovery in more than 2 weeks. No patients experienced serious complications. All patients ultimately displayed pretarsal fullness in their lower eyelids and were satisfied with their outcomes. CONCLUSION The effects of injecting autologous fat to cosmetically enlarge the lower-lid pretarsal roll are long-lasting, esthetic, and safe.

Abstract
BACKGROUND The aim of this study was to evaluate the use of autologous fat graft injection to correct lower eyelid position METHODS: A retrospective, observational, single blind, case-control study was carried out on 94 patients, presenting with lower eyelid retraction in 159 eyes. In the sub-population with monolateral eyelid retraction, the not affected site has been considered as a control and compared with the outcomes recorded after treatment of the contralateral side Follow-up at 12 months was performed with a subjective assessment carried out by a questionnaire administered to patients while objective result assessment was performed 12 months after surgery by two independent blind examiners. RESULTS The eyelid upward reposition has improved one year after fat grafting in both bilateral (1,52 mm) and unilateral (1,7 mm) population: the latter allowed to statistically validate (P<0.05) the result with respect to the not affected site. CONCLUSIONS This is the first paper that highlights the outcomes of sole fat injection in the treatment of lower eyelid retraction: blind objective evaluation of surgical outcomes along with a patient assessment of both functional and aesthetic improvement one year after surgery confirm its efficacy and reliability along with the first case/control outcome evaluation of the technique carried on in the sub-population of 29 patients affected by unilateral lower eyelid retraction that validate the average improvement of the retracted eyelid one year after fat grafting as statistically significant. Nevertheless, longer follow-up periods and a larger sample size are needed to thoroughly confirm surgical outcomes and statistical results.

J Clin Med 2022; 11:jcm11164708. [PMID: 36012947 PMCID: PMC9410081 DOI: 10.3390/jcm11164708] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/25/2022] [Accepted: 07/25/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction: Autologous fat is ideal soft tissue filler. It is easily accessible, biocompatible, cheap, and it provides both volume augmentation and skin quality improvement. Fat grafting has been used since 1893, but it has only gained widespread popularity since the development of modern liposuction by Colemann and Illouz in the 1980s. Every year more than half a million facial fat grafting procedures are carried out worldwide and the trend is rapidly increasing. Overall, general complications associated with facial fat grafting are assumed to be around 2%. Is that true? Material and Methods: Until July 2021, a systematic search of the literature was performed interrogating PubMed search engines. The following algorithm was used for the research: (fat graft OR lipofilling) AND face AND complications. Exclusion criteria applied hierarchically were review articles, not reporting recipient site complications; not in English and paediatric population. Abstracts were manually screened by LS, GS, JM and PDS separately and subsequently matched for accuracy. Pertinent full-text articles were retrieved and analysed and data were extracted from the database. The flow chart of article selection is described following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: In total, 462 papers were identified by PubMed search. A total of 359 were excluded: 38 papers were not in English, 41 were review articles, 279 articles did not report recipient site complications and 1 was not on human subjects. Average complication rate ranged from 1.5% to 81.4%. A total of 298 adverse events were identified: 40 (13.4%) intravascular injections, 13 (4.3%) asymmetry, 57 (19.1%) irregularities, 22 (7.4%) graft hypertrophy, 21 (7%) fat necrosis, 73 (24.5%) prolonged oedema, 1 (0.3%) infection, 6 (2%) prolonged erythema, 15 (5%) telangiectasia and 50 (16.8%) cases of acne activation. Conclusions: FFG related side effects could be resumed in three categories: severe, moderate, and minor. Severe (13.4%) side effects such as intravascular injection or migration require neurological or neurosurgical management and often lead to permanent disability or death. Moderate (38.3%) side effects such as fat hypertrophy, necrosis, cyst formation, irregularities and asymmetries require a retouch operation. Minor (48.3%) side effects such as prolonged oedema or erythema require no surgical management. Despite the fact that the overall general complication rate of facial fat grafting is assumed to be around 2%, the real complication rate of facial fat grafting is unknown due to a lack of reporting and the absence of consensus on side effect definition and identification. More RCTs are necessary to further determine the real complication rate of this procedure.

Abstract
Adipose tissue is a compact and well-organized tissue containing a heterogeneous cellular population of progenitor cells, including mesenchymal stromal cells. Due to its availability and accessibility, adipose tissue is considered a "stem cell depot." Adipose tissue products possess anti-inflammatory, anti-fibrotic, anti-apoptotic, and immunomodulatory effects. Nanofat, being a compact bundle of stem cells with regenerative and tissue remodeling potential, has potential in translational and regenerative medicine. Considering the wide range of applicability of its reconstructive and regenerative potential, the applications of nanofat can be used in various disciplines. Nanofat behaves on the line of adipose tissue-derived mesenchymal stromal cells. At the site of injury, these stromal cells initiate a site-specific reparative response comprised of remodeling of the extracellular matrix, enhanced and sustained angiogenesis, and immune system modulation. These properties of stromal cells provide a platform for the usage of regenerative medicine principles in curbing various diseases. Details about nanofat, including various preparation methods, characterization, delivery methods, evidence on practical applications, and ethical concerns are included in this review. However, appropriate guidelines and preparation protocols for its optimal use in a wide range of clinical applications have yet to be standardized.

Abstract
With developments in the field of tissue engineering and regenerative medicine, the use of biological products for the treatment of various disorders has come into the limelight among researchers and clinicians. Among all the available biological tissues, research and exploration of adipose tissue have become more robust. Adipose tissue engineering aims to develop by-products and their substitutes for their regenerative and immunomodulatory potential. The use of biodegradable scaffolds along with adipose tissue products has a major role in cellular growth, proliferation, and differentiation. Adipose tissue, apart from being the powerhouse of energy storage, also functions as the largest endocrine organ, with the release of various adipokines. The progenitor cells among the heterogeneous population in the adipose tissue are of paramount importance as they determine the capacity of regeneration of these tissues. The results of adipose-derived stem-cell assisted fat grafting to provide numerous growth factors and adipokines that improve vasculogenesis, fat graft integration, and survival within the recipient tissue and promote the regeneration of tissue are promising. Adipose tissue gives rise to various by-products upon processing. This article highlights the significance and the usage of various adipose tissue by-products, their individual characteristics, and their clinical applications.

Abstract
PURPOSE This study designed an efficient measurement method to evaluate the outcome of transconjunctival fat reposition in the tear trough and palpebromalar groove. METHODS AND TECHNIQUES A total of 41 patients (82 eyes) who underwent transconjunctival fat reposition surgery between January 2016 and March 2019 were retrospectively analyzed. Preoperative and postoperative (at least six months) standardized digital images were taken from the patients. A satisfaction survey was conducted on all patients. Their images were analyzed by using the Adobe Photoshop CS5 software. Ratios of the tear trough and palpebromalar groove were calculated. These data were analyzed by SPSS 20.0. RESULTS The overall satisfaction rate was 90.2%. With a partition in the infraorbital region, a line graph showed that the location of the tear trough and palpebromalar groove moved to the upper squares postoperatively. The number of patients whose end points of the tear trough and palpebromalar groove located outside the midline of the pupil decreased by 30.5%. When we processed all the parameters of the preoperative and postoperative groups by profile analysis, a significant difference in the tear trough and palpebromalar groove before and after surgery was observed (right: F = 79.844, P = 0.000 < 0.01; left: F = 161.799, P = 0.000 < 0.01). CONCLUSIONS Digital image analysis is feasible and useful in investigating the improvement of the tear trough and palpebromalar groove. The tear trough and palpebromalar groove shifted up and became shortened, which provided a more reliable evidence for lower eyelid rejuvenation.

The Injection for the Lower Eyelid Retraction: A Mechanical Analysis of the Lifting Effect of the Hyaluronic Acid. Aesthetic Plast Surg 2019; 43:1310-1317.

Abstract
BACKGROUND It has been reported that the injection of the hyaluronic acid (HA) into the lower lid area could improve lower eyelid retraction. However, the published studies offered few insights into the mechanism of this treatment. When the underlying mechanism is not clear, many surgeons will not trust the method enough to apply it in their clinical practice. The purpose of this article was to propose a possible explanation for the underlying mechanism of the treatment and further verify the method by a series of cases. METHODS The authors performed a mechanical analysis on the physical impact of HA on the lower eyelid. In the clinical cases, we injected the fillers under the orbicularis muscle to correct lower lid retraction. The results were evaluated by the standardized marginal reflex distance 2 (MRD2) immediately and 9 months later. RESULTS From October 2013 to October 2015, the injections were carried out in 27 cases (14 post-blepharoplasty and 13 involuntary). In 26 cases (96.3%), the retraction was completely corrected and did not recur through the last follow-up. The average improvement of the standardized MRD2 was 0.84 mm immediately after the injection and 1.19 mm 9 months later. Complications were not reported. CONCLUSION Lower eyelid retraction could be treated by the injection of HA under the orbicularis muscle. The filler in this situation acted as a lifter because the filler changed the balance of force of the lower lid, forcing it to shift upward to gain the new balance. The 'lifter' mechanism could be applicable to other facial injections that generate elevating effects.

Abstract
Tear trough deformity has been an area that has received much attention in terms of esthetic improvements. Fat transposition has been commonly used for the treatment of tear trough deformity. As some patients have had minimal improvement by that method, we propose the use of fat grafting combined with open blepharoplasty to complement the sunken area, including some of anterior maxilla region, and evaluate and precisely remove the excessive tissue.Lower blepharoplasty was performed by separating the skin and muscle flap. The excessive or laxed tissue was evaluated during the procedure and resected in each flap. Fat grafting was performed after completing a lower blepharoplasty, to ensure accurate placement on the spot where the surgeon originally intended. Overcorrection is not recommended.No serious complications were reported during a period of 10 years. Only 4 patients required a secondary fat injection.Patients who require structural correction of the lower eyelid area (eg, aggressive herniated fat, excessive skin laxity, or bulky orbicularis oculi muscle) and who need complementary material to fill the lower lid area (eg, deep, wide sunken area or relative exophthalmos) are good candidates for blepharoplasty with a fat grafting procedure.

Abstract
BACKGROUND Fat grafting to the aging face has become an integral component of esthetic surgery. However, the amount of fat to inject to each area of the face is not standardized and has been based mainly on the surgeon's experience. The purpose of this study was to perform a systematic review of injected fat volume to different facial zones. METHODS A systematic review of the literature was performed through a MEDLINE search using keywords "facial," "fat grafting," "lipofilling," "Coleman technique," "autologous fat transfer," and "structural fat grafting." Articles were then sorted by facial subunit and analyzed for: author(s), year of publication, study design, sample size, donor site, fat preparation technique, average and range of volume injected, time to follow-up, percentage of volume retention, and complications. Descriptive statistics were performed. RESULTS Nineteen articles involving a total of 510 patients were included. Rhytidectomy was the most common procedure performed concurrently with fat injection. The mean volume of fat injected to the forehead is 6.5 mL (range 4.0-10.0 mL); to the glabellar region 1.4 mL (range 1.0-4.0 mL); to the temple 5.9 mL per side (range 2.0-10.0 mL); to the eyebrow 5.5 mL per side; to the upper eyelid 1.7 mL per side (range 1.5-2.5 mL); to the tear trough 0.65 mL per side (range 0.3-1.0 mL); to the infraorbital area (infraorbital rim to lower lid/cheek junction) 1.4 mL per side (range 0.9-3.0 mL); to the midface 1.4 mL per side (range 1.0-4.0 mL); to the nasolabial fold 2.8 mL per side (range 1.0-7.5 mL); to the mandibular area 11.5 mL per side (range 4.0-27.0 mL); and to the chin 6.7 mL (range 1.0-20.0 mL). CONCLUSIONS Data on exactly how much fat to inject to each area of the face in facial fat grafting are currently limited and vary widely based on different methods and anatomical terms used. This review offers the ranges and the averages for the injected volume in each zone. LEVEL OF EVIDENCE III This journal requires that authors assign a level of evidence to each article.

Abstract
Background Parallel to the steady decline in surgical aesthetic procedures to the face, dermal fillers seem to have gained a more prominent place in facial rejuvenation over the last couple of years. As a dermal, facial filler, autologous fat transfer (AFT) seems to have real potential because of the biocompatibility of adipose tissue besides being a procedure with few and primarily minor complications. This systematic review aims to evaluate the available evidence regarding the safety and effectiveness of AFT for facial rejuvenation. Method A systematic review after the Preferred-Reporting-Items-for-Systematic-Reviews-and-Meta-Analysis (PRISMA) statement was conducted. MEDLINE, Embase, and Cochrane Library were searched up to December 2016, with no language restrictions imposed. Case series, cohort studies, and randomized controlled trials (RCTs) reporting on relevant outcomes were included. Results Eighteen clinical articles were included, reporting on 3,073 patients in total over a mean follow-up period of 13.9 months. Meta-analysis showed an overall complication rate of 6% (95% CI 3.0-14.0), with hematoma/ecchymosis (5%), fat necrosis/oil cysts (2%), and irregular fat distribution and scars (both 2%) being among the most reported. No major complications were reported, and the overall patient satisfaction rate was 81%. Conclusion Although the evidence in this systematic review is still limited and plagued by heterogeneity between studies, AFT seems to be a promising method in facial rejuvenation with fewer complications than other fillers and high patient satisfaction rates. Further large-cohort, preferably multicenter, RCTs should substantiate these results through quantifiable volumetric assessment tools and validated patient questionnaires, while adhering to predetermined nomenclature in terms of complications.

Abstract
OBJECTIVE To systematically review the procedure, applications, and outcomes of autologous fat grafting, a promising technique with various clinical applications. PATIENTS AND METHODS Literature review of publications concerning autologous fat grafting. RESULTS Since its introduction, lipofilling has become increasingly popular; however, its results are variable and unpredictable. Several modifications have been made to the procedures of fat harvesting, processing, and injecting. Surgical excision and low negative-pressure aspiration with large-bore cannulas minimize adipocyte damage during fat harvesting. The "wet" method of fat harvesting involves fluid injection at the donor site and facilitates lipoaspiration while minimizing pain and ecchymosis. For fat processing, centrifugation at a low speed is preferable to high-speed centrifugation, gravity separation or filtration. Fat injection at the recipient site should be performed using small-gauge cannulas in a fanning out pattern over multiple sessions, rather than a single session. Fat grafts exhibit not only dermal filler properties but also regenerative potential owing to the presence of stem cells in fat tissue. Thus, the clinical applications of autologous fat grafting include correction of secondary contour defects after breast reconstruction, release of painful scar contractures, and treatment of burn scars and radiodermatitis. Lipofilling is also used in aesthetic surgery, such as facial and hand rejuvenation, augmentation rhinoplasty, and breast and gluteal augmentation. The complications of lipofilling are minimal and include bruising, swelling, pain, infection, necrosis, and calcification. CONCLUSIONS Lipofilling is a low-risk procedure that can be used to correct soft-tissue defects in the face, trunk, and extremities, with minimal discomfort for patients.

Abstract
PURPOSE Upper eyelids of the Asian population have several unique anatomical characteristics that result in the characteristic absence of a native eyelid fold; however, 40% to 60% of the Asian population do exhibit a naturally occurring fold. Aging-associated soft tissue atrophy and loss of skin elasticity can lead to periorbital volume loss and subsequent development of multiple eyelid folds in patients previously with a native single-fold. The authors describe a nonsurgical technique for the management of multiple eyelid folds in Asian patients using hyaluronic acid gel (HAG) injection. METHODS In this retrospective review, 6 upper eyelids of 5 Asian patients who underwent HAG injection for multiple eyelid folds were identified. Patients were injected with HAG superior to the native eyelid fold in a superficial plane just deep to the orbicularis oculi muscle and in the suborbicularis oculi plane of the superior sulcus. RESULTS Five Asian patients with prior history of a single naturally occurring upper eyelid fold who developed age-related unilateral multiple eyelid folds underwent injection with HAG. All patients tolerated the procedure well and without complication. Restoration of a single-fold with bilateral upper eyelid symmetry was achieved successfully in all patients. CONCLUSIONS Multiple eyelid folds may occur in Asian patients with an established naturally occurring single eyelid fold as a result of periorbital volume loss. HAG injection in the periorbital region provides a nonsurgical solution to restore volume and reform a single eyelid fold.

Abstract
INTRODUCTION Many recent studies concerning autologous fat grafting in the eyelids have been published, mostly consisting of case reports and retrospective case series. However, no study on the overall complication or satisfaction rate associated with the various grafting techniques exists. We performed a comprehensive literature review to determine the outcomes and complications of eyelid fat grafting, as well as patient satisfaction. METHODS A systematic review of the literature using the PRISMA criteria was conducted. This protocol was registered at the Prospective Register of Systematic Reviews at the National Institute for Health Research. RESULTS Sixteen studies, representing 1,159 patients and published between June 2004 and December 2014, were included. Satisfactory results, judged by clinical examination, were observed in all studies. Few postoperative complications were reported. CONCLUSIONS We demonstrated that the procedures were easy to perform, and achieved satisfactory and sustainable results with few complications in both reconstructive and cosmetic surgery. However, a wide disparity exists in the various fat harvesting, fat purification, and reinjection techniques. Further studies are required to assess the long-term outcomes. Our conclusions should be accepted cautiously due to the small number of articles and the lack of evidence in published studies.

Abstract
Subcutaneous atrophy is a known complication of steroid injections. Excellent results with fat grafting for the treatment of steroid atrophy have been documented. However, the benefit of treating steroid-induced subcutaneous atrophy in an extremity diagnosed with complex regional pain syndrome (CRPS) has not been described. CRPS, known formerly as reflex sympathetic dystrophy or RSD, causalgia, or reflex neurovascular dystrophy, is a severe, progressive musculoskeletal pain syndrome characterized by pain which is disproportionate to the severity of the inciting event, edema, or skin changes. Common treatment modalities include pharmacotherapy, physical therapy, and nerve blocks-each therapy producing varying results. We present a literature review of CRPS and the case of a 15-year-old female who developed CRPS of the left lower leg after arthroscopic debridement with retrograde drilling of an osteochondral lesion. Steroid atrophy of the involved area following a saphenous nerve block complicated the patient's treatment course. The area of atrophy was treated with autologous fat grafting. Following the adipose injection procedure, the patient experienced almost complete resolution of her CPRS-associated pain symptoms, along with improved cosmetic appearance of the area.
