Inhibition and reversal of a TGF-β1 induced myofibroblast phenotype by adipose tissue-derived paracrine factors

BackgroundHypertrophic scarring results from myofibroblast differentiation and persistence during wound healing. Currently no effective treatment for hypertrophic scarring exists however, autologous fat grafting has been shown to improve scar elasticity, appearance, and function. The aim of this study was to understand how paracrine factors from adipose tissues and adipose-derived stromal cells (ADSC) affect fibroblast to myofibroblast differentiation.MethodsThe transforming growth factor-β1 (TGF-β1) induced model of myofibroblast differentiation was used to test the effect of conditioned media from adipose tissue, ADSC or lipid on the proportion of fibroblasts and myofibroblasts.ResultsAdipose tissue conditioned media inhibited the differentiation of fibroblasts to myofibroblasts but this inhibition was not observed following treatment with ADSC or lipid conditioned media. Hepatocyte growth factor (HGF) was readily detected in the conditioned medium from adipose tissue but not ADSC. Cells treated with HGF, or fortinib to block HGF, demonstrated that HGF was not responsible for the inhibition of myofibroblast differentiation. Conditioned media from adipose tissue was shown to reduce the proportion of myofibroblasts when added to fibroblasts previously treated with TGF-β1, however, conditioned media treatment was unable to significantly reduce the proportion of myofibroblasts in cell populations isolated from scar tissue.ConclusionsCultured ADSC or adipocytes have been the focus of most studies, however, this work highlights the importance of considering whole adipose tissue to further our understanding of fat grafting. This study supports the use of autologous fat grafts for scar treatment and highlights the need for further investigation to determine the mechanism.

Autologous fat grafting and adipose-derived stem cells therapy for acute burns and burn-related scar: A systematic review.

The objective of this study was to analyze all available research on the application of autologous fat grafting (AFG) and adipose-derived stem cells (ADSC) to present evidence-based recommendations, particularly in the clinical treatment of acute burns and burn-related scars. We conducted a systematic search of PubMed, COCHRANE, and EMBASE, as well as a manual search of previous reviews' reference lists up. The risk of bias (RoB) was assessed using RoB 2.0 and ROBINS-I, where appropriate. Six eligible studies were selected (2 randomized clinical trials [RCT], 1 retrospective cohort, and 3 experimental studies) with subjects ranging from 3 to 100. Only one study evaluated the use of AFG for acute burns. Improvements in wound healing, vascularization, scar characteristics, and tissue architecture were generally observed in some studies, supported by molecular markers, while one study reported nonsignificant results. Subjective patient satisfaction was reported to have improved. Functional outcomes improvement in the treated regions was minimal. However, study heterogeneity arose mainly from treatment protocols. Cautious results interpretation due to potential bias, especially in selection and confounding domains, and limited clinical trials are important to note. More studies are needed to evaluate. AFG and ADSC hold potential as valuable treatment options for burn-related scars, supported by a body of evidence, but further well-designed RCT are needed. The efficacy of acute burn settings is yet to be further evaluated since evidence is limited.

Fat Grafting in Vulvar Lichen Sclerosus: Long Term Follow-Up.

The rationale for the use of autologous fat grafting in the treatment of vulvar lichen sclerosus (VLS) consists in reduction of inflammation, regeneration of tissues, volume increase, and pain fiber control. The main outcome of this study was the evaluation of patients' satisfaction after treatment. Secondary outcomes included modifications in symptoms, psychosexual wellbeing, vulvar hydration, and histology after surgery. Eligible for this study were women aged 18-85 years with a histological diagnosis of VLS who underwent at least one autologous vulvar fat grafting at the authors' center, between 2010 and 2019. In 2021, all women underwent a clinical reevaluation, comprehensive of vulvoscopy, vulvar biopsy, and handing out of validated questionnaires. Overall, 88.7% of patients declared themselves very satisfied/satisfied with the procedure. All symptoms were improved postsurgery; in particular, the difference was statistically significant for pruritus, burning, and dyspareunia ( p < .05). Sexual function was also improved at time of reevaluation, as were depressive and anxiety symptoms ( p < .05). No cases of vulvar intraepithelial neoplasia or cancer occurred during follow-up and vulvar architecture remained stable, although patients reported a significantly reduced need for topical steroids ( p < .0001). Lastly, in postoperative biopsies, inflammatory infiltrate was stable or reduced, and the distribution of elastic fibers was comparable or restored in most patients. Patient satisfaction with fat grafting is detectable up to 11 years after surgery, and as such, it may represent a valid therapeutic option in selected cases of VLS.

P16 Patient reported outcomes of cancer survivors with radiation induced fibrosis

Abstract Introduction This study aims to better understand the lived experience of head and neck cancer survivors who suffer from radiation induced fibrosis (RIF). Recording the lived experience of RIF will better inform us on the use of autologous fat grafting (AFG) as a therapy. Methods A focus group (n=5, M=3, F=2) was facilitated, centred around the impact of RIF on head/neck function, appearance, emotional and psychological wellbeing, and socio-economic aspects of participant's lives. Participants discussed the wider issues of cancer survivorship, patient education, and healthcare service provision. Coding and thematic analysis of the verbatim audio transcript was undertaken. We compared this data to currently available patient reported outcome measures, notably the University of Washington Quality of Life Questionnaire (UW-QOL) and modified our survey to encompass these experiences. Results Eight main themes were highlighted, listed in order of importance to patients; 1-Physical head and neck functions 2-Relationship with healthcare providers 3-Socioeconomic aspects of life 4-Appearance 5-Psychological and emotional wellbeing 6-Freedom and independence 7-External/Personal knowledge and sources of information for patients 8-Pain. Quantitative validation of our modified questionnaire, based on these results, and distribution to a wider patient cohort has further demonstrated the severity of symptoms experienced by these cancer survivors. Conclusion There is a clear unmet need for long-term support and novel treatments for this patient group. Future research should focus on treatments such as AFG, which could improve functional outcomes, appearance and emotional wellbeing in RIF patients.

Total Facial Autologous Fat Grafting for Treating Skin Manifestations in Scleroderma.

Systemic sclerosis (SSc) or scleroderma, is a rare, systemic autoimmune connective tissue disease that can cause fibrosis of cutaneous tissue and visceral organs. Facial involvement can have a deleterious effect on patients' function, cosmetic appearance and quality of life. This study describes our experience and results with total facial autologous fat grafting for treating scleroderma. It includes 14 women and 3 men with SSc, at an average age of 51.3 years who underwent 32 autologous fat grafting surgeries between 2017-2022. The surgical technique is further described and demographic and surgical data, including preoperative and postoperative measurements were analyzed. Patients who had multiple surgeries ultimately received grafts with twice the volume of fat than in the first procedure. The oral opening increased an average of 33%. All patients reported improvement in quality of life and were very satisfied with the aesthetic outcomes. The use of autologous fat grafting to treat SSc patients successfully increased oral openings and improved facial manifestations. The procedure is reproducible, safe and leads to improvement in facial manifestations and patients' quality of life. It can be repeated over time to preserve or enhance the results.

Systematic review: Oncological safety of reconstruction with fat grafting in breast cancer outcomes

Autologous fat grafting (AFG) has become a commonly used procedure for breast reconstruction (BR) after cancer removal. Nevertheless, oncological considerations remain for AFG after breast cancer surgery. This article aims to evaluate the oncological safety of AFG in BR and its effect on disease-free survival (DFS) and local-regional recurrences (LRR). A systematic review regarding the use of AFG in BR to identify a difference in incidence rates of LRR and DFS between patients who had AFG and controls was performed using PubMed, MEDLINE, Embase, PreMEDLINE, Ebase, CINAHL, PsycINFO, Clinicaltrials.gov, Scopus, and Cochrane databases. The protocol was developed following the Preferred Reporting for Items for Systematic Reviews-Protocols (PRISMA-P) guidelines. The included studies had to match predetermined criteria according to the PICOS approach. A total of 11 studies were included. Seven studies reported LRR, and 5 studies reported DFS in 5,886 patients. Our systematic review showed that AFG was not associated with increased LRR and DFS. Pooled hazard ratios (HRs) (95% confidence intervals [CIs]) for LRR and DFS were 1.26 (0.90-1.76) and 1.27 (0.96-1.69), respectively. AFG can, therefore, be performed safely in BR after breast cancer. Further, randomized controlled trials and related systematic reviews, as well as evidence-based medicine (EBM) studies of level 1, are required to consolidate the results of the studies identified in this systematic review.

Correction of breast asymmetry by autologous fat grafting with the aid of 3D laser-scanning technology

BackgroundCurrently, the lack of clinically accurate measurement and evaluation methods for breast asymmetry has considerably limited the use of autologous fat grafting in the correction of breast asymmetry. ObjectiveThis study calculated the volume difference in the bilateral breasts by three-dimensional (3D) laser scanning technology, established a bridge between digitalization and surgery to guide the correction of breast asymmetry by autologous fat grafting, and evaluated the surgical effect. MethodsIn the experimental group (3D group), the measurement range was defined by standardized methods, the algorithm to calculate the volume difference in the bilateral breasts was determined by the established software instructions, and the volume of intraoperative autologous fat grafting was guided by personalized data. In the control group, the volume of intraoperative autologous fat grafting was determined based on the surgeon's visual assessment and surgical experience. ResultsThe volume difference in the bilateral breasts was less at 12 months after surgery (P < 0.05), the satisfaction of patients was higher (P < 0.05), and the reoperation rate was lower (P < 0.05). The incidence of postoperative complications was low in both groups (P > 0.05). Conclusions3D laser scanning technology can be used as a bridge between digitalization and surgery to significantly improve the surgical effect of autologous fat grafting in the correction of breast asymmetry, with high patient satisfaction and high clinical application value.

Oncological Safety of Autologous Fat Grafting in Breast Reconstruction: A Meta-analysis Based on Matched Cohort Studies.

Autologous fat grafting has become a commonly used procedure for breast reconstruction after breast cancer surgical treatment. Nevertheless, oncological considerations remain concerning autologous fat grafting after breast cancer surgery. This meta-analysis aimed to summarize the current matched cohort studies and provide high-quality evidence-based conclusions on the oncological safety of fat grafting in breast reconstruction. The Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were followed. A literature search was performed on August 1, 2021, using PubMed. All relevant matched cohort studies of patients undergoing autologous fat grafting after breast cancer surgery were included. After independently screening the studies and extracting the data, pooled estimates for local and regional recurrence as well as distant metastases were conducted using Review Manager software (RevMan, version 5.3). Outcomes were expressed as odds ratios and 95% confidence intervals. Seventeen studies involving 7494 patients were included. The observed outcomes indicated that no significant differences existed in the risks of local and regional recurrence or distant metastases between autologous fat grafting and control groups. Also, there was no significant heterogeneity among the studies. This study provided evidence-based conclusions that support the use of autologous fat grafting in breast reconstruction. This journal requires that authors assign a level of evidence to each article.

Direct use of autologous fat graft on the treatment of lower extremity wounds

Effect of autologous fat transfer in acute burn wound management: A randomized controlled study

ObjectiveThe use of fat grafting is being widely used for different indications one of which is wound healing. In this study we compare the use of autologous fat grafting (AFG) as a novel indication in acute burn wounds healing and burn scarring to the conventional methods of burn wound management both clinically and histologically. Several small observational studies demonstrated the effect of the AFG in healing of chronic wounds, different vascular ulcers or effect on scars yet no randomized controlled trial is available to compare its role with conventional methods. MethodsThe study was a prospective, open-label single center, randomized control clinical trial included 100 patients with superficial and deep dermal burns from March 2019 to March 2020 randomized to AFG protocol consisted of a single injection of autologous fat grafting then dressed with nano fat (Group A) or conventional methods of serial dressings with 1% silver sulphadiazine or other topical agents (Group B). Inclusion criteria included newly admitted burn patients with affected total body surface area (TBSA) (10%−25%) while exclusion criteria included burns patients with affected TBSA of< 10% or> 25%, or loss of subcutaneous fat, fascia, muscles and bones, inhalational burn, and burns in genitalia, perineum and peri-anal areas and co-morbidity(ies) that might affect wound healing or eligibility for anaesthesia and surgery. Also, results were confirmed by histological analysis for samples from both groups by light microscopic examination, and the nano-fat was subjected to flow cytometric analysis of the cluster of differentiation (CD) markers of mesenchymal stem cells markers CD 90, CD44, CD45, CD 73, and CD 34. (ClinicalTrials.gov Identifier: NCT03791710) ResultsWe found a significant reduction in total hospital stay days (p = <0.001), less further skin grafting (p = 0.003), less contracture formation (p = <0.002) while scar texture improved (p = <0.001) in group A compared to group B. Flow cytometric analysis documented that the nano-fat was positive to CD 90, 73, 44, 45 and 34. ConclusionIn a comparison between AFG protocol to the conventional methods in the treatment of acute burn wounds, AFG protocol was associated with significant clinical improvement in the form of lower hospital stay time, lower incidence of scaring or contracture and lower skin grafting use which was confirmed by serial photographic and histological assessment.

Oncological Safety of Autologous Fat Grafting in Breast Reconstruction after Mastectomy for cancer: A case-control study

The use of autologous fat grafting in the context of breast reconstruction is still a matter of controversy. The objective of this study was to compare the local relapse rate in women who had a fat grafting session in the context of breast reconstruction after breast cancer management, to those who had breast reconstruction without fat grafting. We performed a retrospective, monocentric, case-control study from January 2007 to December 2017 in our hospital. The cases included women who underwent breast reconstruction with autologous fat grafting and controls, undergoing breast reconstruction without fat grafting. We compared survival and local recurrence between the two groups. 412 women were included: 109 (26.5%) in the lipofilling group and 303 women (73.5%) in the "no lipofilling" group. In the overall study population, lipofilling did not appear to be a predictive factor for recurrence, HR=1.39 [0.63 - 3.06], p=0.41; or a predictive factor for overall survival, HR=0.84 [0.23 - 3.02], p=0.79, or for distant metastases, HR=1.10 [0.43 - 2.79], p=0.84. In contrast, in the subgroup of women treated for invasive cancer, the multivariate analysis showed that lipofilling in this context was an independent predictive factor for local recurrence (HR= 5.06 [1.97- 10.6], p=0.04). we found an increased risk of local recurrence after lipofilling in women who were managed for invasive breast cancer. This suggests that special consideration should be given to women who have had invasive breast cancer before lipofilling.

Autologous fat grafting for breast reconstruction after breast cancer: a 12-year experience

PurposeThe aim of our study was to examine the surgical outcome and complications (efficiency) as well as the incidence of locoregional recurrence and distant metastases (oncological safety) in patients who underwent autologous fat grafting (AFG) of the breast following breast cancer surgery.MethodsIn our monocentric cohort study, retrospective and prospective data were collected from all consecutive patients who underwent AFG after breast cancer between 2008 and 2020; a total of 93 patients met the inclusion criteria.ResultsOur long-term results showed no increase in tumor recurrence and distant metastases in the studied collective when compared to the available literature. We observed 1 local recurrence (1.1%), 2 distant metastases (2.2%), and 1 tumor-related death (1.1%). There was a high degree of patient satisfaction; 67.12% of patients reported adequate satisfaction with autologous fat grafting.ConclusionCurrently, to our knowledge, this is the study with the longest follow-up time (mean 6.7 years after AFG and 11.5 years after tumor resection). The results of our clinical study will contribute to improve evidence in the broad field of AFG, adipose stem cell and tumor research. Consistent with our study, the literature review shows a clear tendency of clinical trial results with a low incidence rate of tumor recurrence and metastasis following the use of AFG. AFG seems to be a safe procedure also after breast cancer treatment.

QS11: Does the Processing System Matter? A Comparison of Two Filtration Devices in Autologous Fat Grafting for Breast Reconstruction

Purpose:The use of autologous fat grafting (AFG) is becoming increasingly common as an adjunct to breast reconstruction. However, there is a paucity of data comparing the varying processing devices. The goal of this study is to compare the outcomes of two commercially available AFG processing devices.Methods:The authors conducted a retrospective review of patients who underwent AFG using dual filter (Puregraft®) or single filter (RevolveTM) processing systems between 2016 and 2019. Propensity score matching was utilized to adjust for confounding. A total of 38 breasts from the Puregraft® group were matched with 38 breasts from the RevolveTM system.Results:Matching was successful in achieving a similar distribution of baseline characteristics between the two groups. The mean number of AFG sessions was comparable between the two groups (p=0.37) with a similar median total volume (Puregraft®, 159 ml vs. RevolveTM, 130 ml, p=0.23). Complication rates were similar between the two devices (Puregraft®, 26%; RevolveTM,18%; p=0.47). Patients with at least one complication had higher overall AFG volume (median, 200 vs.130 ml, p=0.03) and number of sessions (mean, 2.4 vs.1.8, p=0.009) compared to those without any postoperative complication.Conclusion:The decision for which processing system to use for autologous fat grafting should be based on surgeon preference as overall complication rates were comparable between two commonly used commercially available systems. Future studies are underway to decipher whether either system has superior graft retention, cosmetic or patient reported outcomes.

The Effect of Lipoaspirate Processing Technique on Complications in Autologous Fat Grafting for Breast Reconstruction: A Propensity Score Analysis Study.

The use of autologous fat grafting (AFG) is becoming increasingly common as an adjunct to breast reconstruction. However, there is a paucity of data comparing the varying processing devices. The goal of this study was to compare the outcomes of 2 commercially available AFG processing devices. A retrospective review was conducted of patients who underwent AFG with dual-filter (Puregraft) or single-filter (Revolve) processing systems between 2016 and 2019. Propensity score matching was utilized to adjust for confounding. A total of 38 breasts from the Puregraft group were matched with 38 breasts from the Revolve group. Matching was successful in achieving a similar distribution of baseline characteristics between the 2 groups. The mean number of AFG sessions was comparable between the 2 groups (P = 0.37) with a similar median total volume (Puregraft, 159 mL vs Revolve, 130 mL; P = 0.23). Complication rates were similar between the 2 devices (Puregraft, 26%; Revolve, 18%; P = 0.47). Patients with at least 1 complication had higher overall AFG volume (median, 200 mL vs 130 mL; P = 0.03) and number of sessions (mean, 2.4 vs 1.8, P = 0.009) compared with those without any postoperative complication. Overall complication rates were comparable between 2 commonly used, commercially available AFG processing systems, and therefore the choice of which to use should be based on surgeon preference. Future studies are underway to decipher whether either system offers superior graft retention, cosmetic, or patient-reported outcomes.

Autogenous Fat Transplantation and Botulinum Toxin Injection Into the Masseter Muscle to Create an Ideal Oval Face.

East Asian faces vary in shape but only oval faces seem to be considered attractive. Many patients with wide faces seek removal of part of the mandibular angle and/or zygoma to achieve an ideal facial contour, but the procedure is high risk and the recovery period is relatively protracted. We sought to achieve ideal facial contours through the use of autologous fat grafting (AFG) combined with masseter botulinum toxin (BTX) injection for patients with wide faces and masseter hypertrophy. Fourteen patients with wide faces underwent AFG of the forehead, temporal region, cheeks, zygomatic body, nose, nasolabial fold, tear trough, and chin; and BTX injection into the masseter muscles. Each patient was photographed more than 6 months after the operation. The pre- and postoperative ratios pertaining to the facial aesthetics of the face were calculated. The Hollowness Severity Rating Scale (HSRS) and Ricketts's E-line were used to evaluate the photographs. Patient satisfaction was also investigated. All patients received AFG and 1 to 3 BTX injections. The face length:bizygomatic breadth, bigonial breadth:bizygomatic breadth, and lower-face height:middle-face height ratios improved greatly after treatment. The mean HSRS score decreased from 2.214 preoperatively to 1.071 postoperatively. The chin and nose became more prominent than before. Facial swelling persisted for an average of 11.929 days. All patients were satisfied with the treatment outcome. A combination of AFG and BTX injection was able to achieve an ideal oval face in East Asian patients with wide faces and masseter hypertrophy, with very few complications. Recovery was rapid and patient satisfaction was high.

Guided neural regeneration with autologous fat grafting and oxygen hyperbaric therapy.

The loss of continuity of the nerve structure interrupts the transmission of nerve impulses and leads to the disorganization of functional activities. Many methods, as the use of neurogenic factors, aid in the process of neural regeneration by accelerating or improving peripheral nerves neoformation. The adipose tissue is abundant in the human body, and it has presented promising results in the regeneration of peripheral nerves. We carried out a randomized controlled study in 9 months, using 45 male Wistar rats, 80 days old, and the sciatic nerve was chosen for analysis. The control animals were divided into three groups - Initial group (IG), Final group (FG), and denervated group (DG) - with seven animals each. The experimental groups, with twelve animals each, were polyethylene tube filled with fat (EGF) and polyethylene tube without filling (EGwf). All groups, except IG, were submitted to 10 sessions of hyperbaric oxygen treatment of 1h 45 min in alternating days. Functional evaluation by walking-track was assessed using the Catwalk XT® software and tissues were harvested and stained with 1% toluidine blue for histological analysis. Quantitative data were first analyzed with the Kolmogorov Smirnov normality test. Comparison between the four groups was analyzed by ANOVA followed by Tukey Test. We concluded that hyperbaric oxygen therapy had positive results on morphometric and functional parameters. However, no significant differences were found regarding the use of autologous fat graft.

Safety and Effectiveness of Autologous Fat Grafting after Breast Radiotherapy: A Systematic Review and Meta-Analysis.

The purpose of this study was to evaluate the safety and effectiveness of autologous fat grafting after radiotherapy. All studies published before December of 2019 were collected by searching on PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure, and Wanfang Data. After independently screening the studies and extracting the data, Stata was applied to perform meta-analysis. Seventeen qualified articles were eventually included, involving a total of 1658 patients, of which 1555 underwent autologous fat grafting. Overall, empirically from the data, the use of autologous fat grafting after radiotherapy does not increase the incidence of complications or the risk of tumor recurrence. Through statistical analysis, the authors found that 152 patients suffered complications after undergoing autologous fat grafting [152 of 1555 (9.8 percent)]; 72 patients suffered complications after undergoing postradiotherapy autologous fat grafting [72 of 1040 (6.9 percent)], including seven cases of tumor recurrence [seven of 1040 (0.7 percent)]; and 80 patients suffered complications after undergoing autologous fat grafting without radiotherapy [80 of 515 (15.5 percent)], including seven cases of tumor recurrence [seven of 515 (1.4 percent)]. The authors also found that 970 of 1040 patients (93.3 percent) were satisfied with the results of postradiotherapy autologous fat grafting for breast reconstruction. This study has provided an evidence-based conclusion supporting the use of autologous fat grafting for breast reconstruction after radiotherapy. Autologous fat grafting can effectively correct breast deformity and contracture caused by breast-conserving therapy and radiotherapy and increase patient satisfaction without increasing the rate of tumor recurrence.

Autologous Mastopexy and Autoaugmention of the Breast.

Background:Autologous mastopexy is an alternative for patients with small breasts, ptosis and upper pole hollowness, who desire improvement in their breast shape without using an implant. A variety of techniques have been tried throughout the years. Recently the use of autologous fat grafting (AFG) for breast augmentation increased in popularity and showed satisfying cosmetic outcome in enhancement of size, shape and texture of the breast.Methods:25 patients with grade 2 ptosis were included in this study. Lower Island Flap Transposition (LIFT) technique was modified and either done alone or in combination with lipofilling, whether at the same setting or as a second stage. Preoperative and postoperative measurements and pictures were documented.Results:Lateral upper pole projection measurements showed an average increase of 28.5% equal to about 1.8 cm. As for the maximum breast projection an increase of about 33% accounting for about 2 cm was documented.Conclusions:This study shows that the combination of LIFT technique after its modification with AFG has proven to be an effective technique with consistent results for patients presenting with grade 2 ptosis and upper pole hollowness. The addition of AFG to the modified LIFT technique can be considered a step forward in achieving autoaugmentation and autologous mastopexy without using implants.

The Current Status of the Autologous Fat Grafting for Pediatric Craniofacial Patients.

Since its first introduction, autologous fat grafting (AFG) has undergone multiple refinements and has become a common treatment option within plastic surgery. It is a safe, quick, economical, and minimally invasive method for volume augmentation and is finding its own indications in the pediatric craniofacial surgery patients. Because there is currently a paucity of literature regarding the use of AFG in the pediatric population compared with the adults, the authors performed a systematic review of the literature using PubMed, Cochrane Library databases, and the Journal of Plastic and Reconstructive Surgery using the terms of fat grafting/lipofilling, fat grafting, and craniofacial surgery to include articles that contained pediatric patients. While reviewing AFG in the pediatric craniofacial patients, indications, technique, and challenges were specifically evaluated and an algorithm of approach was proposed. In current practice, the choice of microvascular free flap versus AFG is one of the surgeon preferences on a case-by-case basis. With the low complication rate and ease of use, selection of AFG for the repair of soft tissue defects in pediatric craniofacial patients is increasing and may come to surpass use of traditional invasive methods such as free flaps. It should also be considered as a useful adjunct to other concurrent invasive procedures, that is, bony adjustments.

Secondary "Hybrid Reconstruction" Concept with Silicone Implants After Autologous Breast Reconstruction - Is It Safe and Reasonable?

BackgroundThe use of autologous tissue for breast reconstructive surgery following mastectomy has become routine and allows for excellent symmetry and aesthetic results. However, in some cases, the amount of tissue available from the utilized flaps is not enough to achieve the desired outcome. The use of autologous fat grafting, as well as other techniques, has been described to deal with such problems. However, though well-established, these techniques may also fail to achieve the desired results. The aim of this study was to highlight the opportunity to improve aesthetic results using a secondary prosthesis underneath the previously used free flap and to examine whether this is a safe and reasonable procedure.Material/MethodsIn our study we included patients with unsatisfied aesthetic results after free flap procedures (DIEP, S-GAP, TMG, and FCI) between 2011 and 2018. In each case described, a secondary prosthesis was placed underneath the original flap in order to improve symmetry, shape and projection. Patient age, indication for surgery, adjuvant therapy, complications and outcomes have been registered. A 12-point scale was established to analyze patient satisfaction and aesthetic outcome.ResultsOverall “operative success” was achieved in all 13 patients (14 flaps) evaluated. At 12 months after reconstruction, all aesthetic scores collected were between good and excellent. In contrast to other studies, we chose a secondary approach for the flap augmentation and we used the epipectoral pocket for the placement of the implant. In our series, low rates of early and late post-operative complications were observed, with a high overall rate of satisfaction.ConclusionsThe demonstrated “Hybrid Breast Reconstruction” approach, using an implant underneath a free flap autologous breast reconstruction, provided a safe and reliable option to optimize breast reconstruction outcomes.
