ABSTRACT

PURPOSE: To investigate the efficacy of the retroseptal transconjunctival blepharoplasty together with tear trough ligament (TTL) and Orbicularis retaining ligament (ORL) release with orbital fat graft in the management of groove in the infraorbital region (GIR). METHODS: A prospective study of 80 eyes of 40 patients that underwent retroseptal transconjunctival lower blepharoplasty together with TTL and ORL release and resected orbital fat grafting. An ophthalmic examination includes lower eyelid evaluation and Barton's Tear trough deformity grading was done at baseline, 2 weeks, 3 months, and 6 months after the surgery. Patient satisfaction was evaluated using Global aesthetic improvement scale (GAIS) and Blepharoplasty outcomes evaluation (BOE). RESULTS: Baseline tear trough defects were graded into grade 1, 2, and 3 in 12 (15%), 39 (48.75%) and 29 (36.25%) eyes, respectively. While at 6 months follow-up, grade 0 was recorded in 63 (78.75%) eyes, and grade 1 was recorded in 17 (21.25%) eyes. The amount of fat removed was 0.52 ± 0.04 mL per eye, whereas the amount of injected fat graft was 0.24 ± 0.04. The mean operative time was 33.2 ± 4.1 min per eye. GAIS showed degree 1, 2, and 3 in 8 (20%), 29 (72.5%), and 3 (7.5%) patients at 6 months follow-up, respectively. The mean baseline BOE increased significantly from 36.5 ± 5.9 to 86.9 ± 5.5 at 6 months follow-up. CONCLUSIONS: Our cohort highlights the beneficial effects of TTD/ORL release with resected orbital fat grafting in the management of GIR and infraorbital hollow.

ABSTRACT

BACKGROUND: Fat transfer has been widely used after breast conservative surgery (BCS) where it aims to recover shapes as a simple, inexpensive, biocompatible method but the technique is not without complications. Platelet Rich Plasma (PRP) is a promising approach to enhance fat graft survival and subsequently improve the outcome. The aim of this study was to evaluate the effect of enriching fat graft with PRP for delayed correction of deformities after conservative surgery for breast cancer regarding esthetic outcome and incidence of complications. METHODS: The current study included 50 female patients who were scheduled for delayed lipofilling for correction of deformities after conservative surgery for breast cancer. The studied patients were randomly allocated into 2 groups: Group I (G I) included 25 patients scheduled for PRP enriched lipoinjection and Group II (G II) included 25 patients scheduled for lipoinjection without PRP as a control group. RESULTS: Number of sessions of lipoinjection was significantly less in G I in comparison to G II (P = 0.024). During the 2nd session; the amounts of fat injected and harvested were significantly less in G I in comparison to G II (P = 0.049 and 0.001 respectively). Recipient site complications were significantly more evident in G II in comparison to G I (P = 0.01). Surgeon and patient satisfactions were significantly more evident in GI in comparison to G II (P = 0.005 and 0.029 respectively). CONCLUSION: The addition of PRP to fat grafts is a simple, cost-effective and safe method to improve esthetic outcome and decrease complications.

ABSTRACT

Regenerative therapies such as fat grafting and Platelet Rich Plasma (PRP) have emerged as new options to tackle burn-related injuries and their long-term sequelae. Fat grafting is able to promote wound healing by regulating the inflammatory response, stimulating angiogenesis, favoring the remodeling of the extracellular matrix, and enhancing scar appearance. PRP can enhance wound healing by accelerating stages including hemostasis and re-epithelization. It can improve scar quality and complement fat grafting procedures. Their cost-effectiveness, minimal invasiveness, and promising results observed in the literature have made these tools as therapeutic candidates. The current evidence on fat grafting and PRP in acute and reconstructive burns is described and discussed in this study.

ABSTRACT

Nasal septal perforation (NSP) is a complex problem in otorhinolaryngology, which leads to impaired nasal breathing and dryness in the nose. This reduces the patient's quality of life and leads to psychological discomfort. The treatment of nasal septum perforation is selected taking into account the clinical manifestations, perforation parameters and general condition of the patient. Currently, a large number of different surgical methods have been described in order to closing the defect of nasal septum. To date, there is no universally accepted method for closing NSP, which stimulates the search and development of new treatment options. OBJECTIVE: Under experimental conditions, to study a new method for closing nasal septum perforation using a collagen scaffold together with adipose stromal vascular fraction containing multipotent mesenchymal stromal cells. MATERIAL AND METHODS: The experiment was carried out on a model of nasal septum perforation in 24 male rabbits divided into four groups, depending on the construct, implanted into the defect zone: the 1st group was the control group - without the introduction of implantation material; the 2nd group - collagen scaffold without adipose stromal vascular fraction; the 3rd group - collagen scaffold with xenogenic adipose stromal vascular fraction; the 4th group - collagen scaffold with allogeneic adipose stromal vascular fraction with further dynamic evaluation of endoscopic control on day 14, after 1 month, 3 months, and 6 months. At month 6, the animals were removed from the experiment, followed by morphological examination in color with hematoxylin and eosin, as well as safranin and methyl green. RESULTS: As a result of the experiment using adipose stromal vascular fraction of allogeneic and xenogenic origin, closing of perforation of the nasal septum of a rabbit for 3 months of dynamic endoscopic control, as well as according to morphological research, was demonstrated. CONCLUSION: Our study showed that the use of adipose stromal vascular fraction containing not only endothelial cells and pericytes, but also multipotent mesenchymal stromal cells in combination with a collagen scaffold closes the perforation of the nasal septum in a rabbit, without increasing the risk of violations of habitual vital activity.

ABSTRACT

BACKGROUND: Keloid is a dermal fibroproliferative disease unique to humans. Due to the ambiguity in its pathophysiology and the frequent recurrence of keloid, there is no clear consensus on the treatment of keloid and there are many treatment methods defined. In order to benefit from the positive effects of fat grafting on pathological scars, we applied fat grafting to patients who underwent keloid enucleation. METHODS: Fifteen ear keloid patients included in the study. All patients underwent the same surgical procedure by the same surgeon. Routine follow-ups and examinations were performed to evaluate the results and in addition, the Patient and Observer Scar Assessment Scale (POSAS) survey was used. RESULTS: In the study, 15 patients were followed for a median (IQR) period of 21 (13-28) months. No recurrence was observed in any patient during follow-up, which occurred for a median of 21 (13-28) months. In the questionnaire filled out by the patients, the preoperative median value was found to be 48 (IQR: 12), whereas the postoperative median value was found to be 14 (IQR: 8). According to the patients, there was a statistically significant ( P < 0.05) positive improvement after surgery. CONCLUSIONS: Historically, surgical procedures were avoided because the surgical recurrence rate was very high, but today, recurrence rates are decreasing with combined treatments. These treatment combinations may require more than one intervention and require frequent clinical follow-ups. With our technique of fat grafting after enucleation, the treatment was completed with a single operation and no additional intervention was required.

ABSTRACT

Gold standard method for the treatment of critical-sized bone defects is the autogenous bone grafting procedure. A number of new and potentially useful adjuncts currently are being investigated to enhance the success of bone grafting. We propose to evaluate the effect of the most known and easily obtained 2 biological materials, fat graft and platelet-rich plasma (PRP), on bone graft healing. Twenty-seven New Zealand male rabbits were included in this randomized, controlled study. Two-sided 15-mm diameter bone defects were created in the parietal bones and the bones taken were replaced right-to-left and vice versa with 1 control group, 1 fat graft applied group, and the last one PRP applied group. Histologic evaluation and 3-dimensional maxillofacial computerized tomography were performed and bone density was calculated. In radiologic analysis, bone density was significantly different in the PRP group compared with the control and fat graft group in the 12th week ( P <0.05). In histologic scoring analysis, the PRP group had a better score than the control and fat graft group, while the fat graft group was worse than the control group in the 6th week ( P <0.05). The addition of PRP had a positive effect whereas fat graft had a negative effect on bone graft healing compared with the control group.

ABSTRACT

BACKGROUND: Recently, micronized adipose tissue (MAT) grafts have shown promising results in wound healing, including diabetic ulcers. OBJECTIVE: To assess the possibility of using 3D printed MAT niche grafts in the management of skin and soft tissue defects resulting from non-melanoma skin cancer (NMSC) resections. MATERIALS AND METHODS: A retrospective feasibility study was conducted on patients with skin and soft tissue defects resulting from NMSC resections. Twenty-one patients were treated using either artificial dermis (n = 11) or MAT niche (n = 10) grafting. Healing time and POSAS scores were compared. The Mann-Whitney U test and the Pearson chi-square test were used in statistical analysis to compare between and within groups based on preoperative and postoperative measurements. RESULTS: Wounds in the MAT niche group reepithelialized significantly faster than those in the artificial dermis group (mean [SD] 39.2 [11.4] days vs 63.7 [34.8] days; P = .04). In the 21 scar parameters evaluated, the MAT niche group demonstrated significantly superior outcomes in only 2 parameters based on operator assessment scores: relief (mean [SD] 1.6 [0.7] vs 2.2 [0.6]; P = .047) and scar contracture (mean [SD] 1.3 [0.5] vs 2.5 [1.0]; P = .011). CONCLUSION: This study proves the feasibility of exploring the effects of MAT niche grafting following NMSC excision on healing time and specific parameters of scarring, including scar relief and scar contracture.

ABSTRACT

BACKGROUND: There is currently no standardization in the field of research on fat grafts in rats, which is one of the most popular topics in plastic surgery. The aim of our study was to demonstrate the effects of selecting paraepididymal fat grafts as the donor area on enhancing the reliability of fat graft studies. METHODS: In this study, 12 male Sprague-Dawley rats were used to obtain adipose grafts from both inguinal and paraepididymal regions. After measuring the graft weights, they were subjected to histological examination using hematoxylin-eosin staining, as well as immunohistochemical staining with antiperilipin antibody. Purity of the samples, viability of adipose cells, and the presence of lymph nodes within the grafts were analyzed. RESULTS: The purity of adipose cells in graft samples obtained from the paraepididymal region was found to be 98.1% compared with the total sample. In contrast, the purity of adipose cells in graft samples obtained from the inguinal region was 58.37%. Hematoxylin-eosin staining revealed significantly higher adipocyte viability and vascularity in the paraepididymal region compared with the inguinal region (P = 0.0134). Conversely, lymphatic tissue content in samples obtained from the inguinal region was significantly higher compared with paraepididymal adipose tissue samples (P < 0.0001). Immunohistochemical staining with antiperilipin antibody showed a denser and more uniform staining pattern in paraepididymal adipose grafts (P < 0.0001). CONCLUSIONS: Using paraepididymal fat, devoid of lymphatic tissue, naturally eliminates 2 critical biases (estrogen and lymphatic tissue), enhancing the standardization and reliability of fat graft survival studies.

ABSTRACT

Radiotherapy is important in breast cancer treatment. A side effect of the treatment is fibrosis that decreases the possibility for a successful breast reconstruction with expanders and with high patient satisfaction with the result. The most common option for mastectomized, irradiated women wishing for a breast reconstruction is autologous tissue transplantation. However, some patients are not suitable for flap surgery. Fifty mastectomized and irradiated women were included in a randomized controlled trial. They underwent breast reconstruction with expanders and were allocated 1:1 to either receive pre-treatment with autologous fat transplantation (AFT) or not. Primary outcomes were frequency of reoperations and complications. Secondary outcomes were number of days in hospital, number of outpatient visits to surgeon or nurse and patient reported outcome as reported with Breast Q. Follow-up time was 2 years. Fifty-two per cent of the intervention group and 68% of the controls underwent reoperations (p = 0.611). Thirty-two per cent of the intervention group and 52% of the controls had complications (p = 0.347). The median number of consultations with the nurse was four in the intervention group and six in the control group (p = 0.002). The AFT patients were significantly more satisfied with their breasts and psychosocial well-being after 2 years. They also had higher increase in satisfaction with breasts, psychosocial well-being, and sexual well-being when comparing baseline with 2 years postoperatively. This randomized controlled trial indicates benefits of AFT prior to breast reconstruction with expanders, especially on patient reported outcome even if the study sample is small.

ABSTRACT

INTRODUCTION: Autologous fat grafting is a method of improving aesthetic outcomes after both breast reconstruction and aesthetic surgery through volume enhancement and tissue contouring. Long-lasting effects are linked to greater patient satisfaction and more optimal augmentation results. Harvesting, processing, and injection techniques may all affect the longevity of deformity filling. Our objective is to evaluate the effect of lipoaspirate processing modality on longitudinal volume retention after surgery. METHODS: A prospective, single-institution, randomized control trial placed consented postmastectomy fat grafting patients into 1 of 3 treatment arms (active filtration, low-pressure decantation, and standard decantation) in a 1:1:1 ratio. A preoperative 3-dimensional scan of the upper torso was taken as baseline. At the 3-month postoperative visit, another 3D scan was taken. Audodesk Meshmixer was used to evaluate the volume change. RESULTS: The volume of fat injected during the initial procedure did not differ significantly between the treatment arms (P > 0.05). Both active filtration and low-pressure decantation resulted in higher percentage volume retention than traditional decantation (P < 0.05). Active filtration and low-pressure decantation exhibited comparable degrees of fat maintenance at 3 months (P > 0.05). DISCUSSION: Compared with using traditional decantation as the lipoaspirate purification technique, active filtration and low-pressure decantation may have led to higher levels of cell viability by way of reduced cellular debris and other inflammatory components that may contribute to tissue resorption and necrosis. Further immunohistochemistry studies are needed to examine whether active filtration and low-pressure decantation lead to lipoaspirates with more concentrated viable adipocytes, progenitor cells, and factors for angiogenesis.

ABSTRACT

INTRODUCTION: Autologous fat grafting (AFG) is a common technique used to enhance aesthetic outcomes in postmastectomy breast reconstruction patients. Adipokines are hormones secreted by adipose tissue that play a critical role in regulating metabolic processes and the immune system. However, dysregulated adipokine secretion and signaling can contribute to the development and progression of cancer by promoting angiogenesis, altering the immune response, and inducing the epithelial mesenchymal transition. We aimed to assess how breast cancer cells behave in conditioned media derived from fat grafting lipoaspirates and gain a better understanding of the potential interactions that may occur within the tumor microenvironment. METHODS: Patients who were undergoing AFG as a part of breast reconstruction at NY-Presbyterian/Weill Cornell Medical Center between March 2021 and July 2023 were consented and enrolled in the study. This study was approved by the Weill Cornell Medicine Institutional Review Board (#20-10022850-14). Conditioned media is created using 20% of patient lipoaspirate secretome and 80% starving media. The growth of MCF-7, a human ER/PR+ breast cancer cell line, in conditioned media is assessed using CyQUANT. RESULTS: The breast cancer cells incubated in conditioned media displayed similar growth trends as those in complete media, which is enriched for cell growth (P > 0.05). MCF-7 cell behavior in conditioned media differed significantly from their proliferation patterns when serum starved in 100% starving media (P < 0.05). DISCUSSION: Our results suggest that there may be inherent factors within the lipoaspirate that may promote MCF-7 proliferation. One potential implication is that AFG used for breast reconstruction should be delayed until local-regional disease control has been established. In addition, based on the in vitro proliferation patterns of breast cancer cells in conditioned media, the safety profile of AFG may be enhanced if the procedure is performed after attaining negative margins and the completion breast cancer treatment.

ABSTRACT

Post-mastectomy pain syndrome (PMPS), characterized by persistent pain lasting at least three months following mastectomy, affects 20-50% of breast surgery patients, lacking effective treatment options. A review was conducted utilizing EMBASE, MEDLINE, and all evidence-based medicine reviews to evaluate the effect of fat grafting as a treatment option for PMPS from database inception to 29 April 2023 (PROSPERO ID: CRD42023422627). Nine studies and 812 patients in total were included in the review. The overall mean change in visual analog scale (VAS) was -3.6 in 285 patients following fat grafting and 0.5 in 147 control group patients. There was a significant reduction in VAS from baseline in the fat grafting group compared to the control group, n = 395, mean difference = -2.17 (95% CI, -2.95 to -1.39). This significant improvement was also noted in patients who underwent mastectomy without reconstruction. Common complications related to fat grafting include capsular contracture, seroma, hematoma, and infection. Surgeons should consider fat grafting as a treatment option for PMPS. However, future research is needed to substantiate this evidence and to identify timing, volume of fat grafting, and which patient cohort will benefit the most.

ABSTRACT

Osteoarthrosis is a degenerative musculoskeletal disease that presents a major public health problem, due to the increasing average age of the active population, as well as the increasing percentage of obesity or overweight of the general population. New therapeutic approaches have been developed, such as regenerative medicine that uses mesenchymal stromal cells taken from adipose tissue. This study analyzed the clinical potential benefits of using autologous adipose tissue to treat patients with moderate-severe knee osteoarthritis.In 2021, a total of 50 knees, affected by moderate-severe knee osteoarthritis, were treated with an intra-articular injection of micro-fragmented subcutaneous adipose tissue. Patients were submitted to the KOOS questionnaire before the operation and one year after the operation and VAS pain score at time 0, 3, 6, 12 months.Of the 50 patients treated, 2 patients were excluded from the study. Of the remaining 48 patients, improvements have been achieved in all subclasses of KOOS. In particular, VAS score proves that improvements are more considerable starting from the 3rd month after surgery.The results obtained in this study show the safety and potential benefit of the use of autologous micro-fragmented adipose on people who are affected by moderate-severe knee osteoarthritis.

ABSTRACT

The aging process of lower eyelids results in lower eyelid wrinkles, tear troughs, and eye bags. Many therapies have been described for treatment of lower eyelid aging, and transcutaneous blepharoplasty is often used for treating cases with eyebags and dermatochalasis. However, it may cause depression near the medial orbit resulting in a hollowed look. In the present study, we developed an innovative method transferring the herniated fatty tissue to volume loss area during the surgical procedure of transcutaneous lower eyelid blepharoplasty by means of micro-autologous fat transplantation harvested from resected orbital fat pads. Besides, we also analyze it efficacy and safety compared with traditional methods of transcutaneous lower eyelid blepharoplasty. We reviewed the records of the patients who underwent transcutaneous lower eyelid blepharoplasty with and without micro-autologous fat transplantation, for lower eyelid aging improvement. We used global aesthetic improvement scale, Hirmand's classification system, and Wrinkle Severity Rating Scale to evaluate the cosmetic outcome at 1 week, 1 month, and 3 months after operation by two independent investigators. We found patients received transcutaneous lower eyelid blepharoplasty with autologous fat graft had significantly higher global aesthetic improvement scale and Wrinkle Severity Rating Scale improvement than those underwent transcutaneous lower eyelid blepharoplasty only in each evaluation timepoints. There was no significant difference of adverse effects between both surgical methods. The present study demonstrated the efficacy and safety of the lower eyelid blepharoplasty with micro-autologous fat transplantation harvesting from resected orbital fat pads.

ABSTRACT

Facial fat grafting is a popular cosmetic procedure, and experts are increasingly endorsing the use of high-density fat with adipose stem cell glue for better results. This study aims to explore the effect of high-density fat combined with adipose stem cell glue on the success rate of facial filling and its clinical value. We conducted a randomized trial with 100 patients who underwent facial fat transplantation between August 2020 and August 2022. They were divided into two groups: a control group receiving traditional Coleman fat transplantation and an observation group receiving high-density fat with adipose stem cells. In the observation and control groups, the excellent and good rate was 98.00 and 80.00%. After 3 months of treatment, the thickness of frontal subcutaneous fat and temporal subcutaneous fat in the observation group was higher (P < 0.05). Observation group retention of fat transplantation was noticeably higher 3 months after treatment (P < 0.05). Three months after treatment, the VISIA (facial imaging system) scores of facial color spots, facial pores and facial wrinkles in the observation group were lower (P < 0.05). After treatment, both groups indicated noticeable improvements in physiological functions, health status, social function, mental health, and somatic diseases compared to before treatment. Notably, the observation group had higher scores (P < 0.05). The observation group had a lower complication rate (4.00% vs. 22.00%) and higher satisfaction rate (98.00% vs. 86.00%) than the control group. Using high-density fat combined with adipose stem cell glue for facial fat grafting yields superior results, reduces complications, and boosts patient satisfaction compared to traditional methods. We have complied with all relevant ethical regulations with regard to the use of stem cells.

ABSTRACT

INTRODUCTION: Autologous fat transfer (AFT) is widely used to improve results of breast reconstructive surgery, but its safety is controversial. Our objective was to evaluate the oncologic safety of AFT in a homogeneous population of patients who underwent a total mastectomy with immediate reconstruction for breast cancer. METHODS: We performed a retrospective cohort study by identifying all patients who underwent immediate breast reconstruction after mastectomy for breast cancer from 2007 to 2015 in our center. A patient group with AFT performed in the 24 months after mastectomy was compared to a control group. RESULTS: Five hundred fifty cases were included, of whom 136 (24.7%) underwent at least one fat graft transfer. Median age was 51 years. Reconstruction was performed in 465 (84.5%) with an implant reconstruction. The median time from mastectomy to AFT was 13.8 months. The median follow up was 55.2 months. A total of 53 events were observed, including 10 (7.4%) in the AFT group and 43 (10.4%) in the control group. There was no difference in 5-year recurrence-free survival (RFS) between the groups. In the subgroup analysis, only lymph node involvement in patients who underwent AFT in the first 24 months after oncologic surgery appeared as a risk factor of recurrence. Among the 104 patients with lymph node involvement, 5-year RFS was 69.2% in patients with lipofilling vs 92.5% in patients without it (p = 0 0.0351). CONCLUSION: Performing early lipofilling in primary breast reconstruction after mastectomy for cancer seems to be oncologically safe. Lymph node involvement increases the risk of recurrence in this population.

ABSTRACT

BACKGROUND: Although endoscopic mastectomy has been associated with good tolerance and enhanced patient satisfaction, limitations such as the implant or flap size for reconstruction with small incisions remain unresolved. Fat grafting (FG) can expand tissue volume with pinhole skin incisions. Herein, we evaluated the safety and efficacy of endoscopic mastectomy followed by immediate FG. METHODS: Patients who underwent endoscopic mastectomy with immediate FG reconstruction from 2015 to 2021 were retrospectively evaluated to establish surgical outcomes and prognosis. RESULTS: Twenty-three patients with clinical stage 0 or I breast cancer underwent unilateral endoscopic mastectomy with immediate FG. The median age was 45 years (41-55), and the median body mass index was 19.3 kg/m2 (15.8-26.6). Endoscopically performed procedures included skin-sparing mastectomies in 18 patients (78%) and nipple-sparing mastectomies in five patients (22%). The median procedure duration was 295 min (242-346). The median specimen weight was 133 g (71-334), and the median grafted fat volume was 200 mL (136-320). No patient required reoperation or additional procedures for complications. One patient experienced recurrence at a median follow-up of 56.1 months and underwent resection; the patient was alive without recurrence 54 months post-resection. CONCLUSION: To the best of our knowledge, this is the first report of endoscopic mastectomy with immediate FG for reconstruction. When compared with other immediate autologous reconstructions, our strategy could minimize the skin incision and procedure duration, as well as limit complications. Further prospective investigations are needed to evaluate oncological safety, surgical outcomes, and patient satisfaction.

ABSTRACT

OBJECTIVES: The management of idiopathic subglottic stenosis (iSGS) poses a clinical challenge due to high recurrence rates following both endoscopic and open approaches, often leading to tracheostomy. The activation of abnormal T-cells and cytokine pathways has been linked to iSGS pathogenesis. Autologous adipose tissue centrifugation yields lipoaspirate, offering optimal anti-inflammatory effects and biocompatibility widely utilized in various medical settings. This report presents the first 3 cases employing endoscopic dilation (ED) in combination with local lipoaspirate injection to address recurrent iSGS. METHODS: A prospective observational study was conducted, involving multidisciplinary evaluation by the Tracheal Team at the University of Modena. Patients meeting specific criteria were directed to undergo ED + lipoaspirate injection. RESULTS: Three patients fulfilled the inclusion criteria. The mean number of prior endoscopic procedures performed was 8. Endoscopic examination revealed 90% stenosis in patient A, 60% stenosis in patient B, and 60% stenosis in patient C. All patients presented inflammatory tissue or incipient granulations at the stenotic site, with an average time of 6 months between previous procedures. After 15 months, none of the patients required further procedures, and endoscopic examination revealed a significant reduction or disappearance of inflammatory tissue with a stable airway lumen. CONCLUSIONS: The observed results are encouraging in terms of reducing local inflammation and halting stenosis progression, especially in cases of short-term relapsing iSGS.
