Clinical effect of botulinum toxin type A combined with autologous fat grafting in patients with nasolabial fold depression

BACKGROUND Nasolabial fold(NLF)depression can affect the facial appearance of patients to some extent and increase their psychological burdens.In recent years,autologous fat grafting(AFG)combined with botulinum toxin A(BTX-A)injection(AFG+BTX-A injection)has been gradually applied in the treatment of patients with NLF depression.Although studies have been conducted on the efficacy and safety of AFG+BTX-A injection in treating NLF depression,the experimental design,observational indicators,and sample enrollment criteria vary remarkably,making it difficult to draw convincing and consistent conclusions.Thus,further relevant research is warranted.AIM To assess the esthetic improvement,efficacy,and safety of AFG+BTX-A injections in patients with NLF depression.METHODS This study included 60 patients with NLF depression who were treated in our hospital from February 2019 to April 2021.These patients were categorized into control(n=30)and observation(n=30)groups.The observation group received AFG+BTX-A injection,whereas the control group underwent AFG only.All patients were evaluated using the wrinkle severity rating scale(WSRS)and global aesthetic improvement scale.The compactness of facial contours,skin evaluation indexes,adverse reactions,and satisfaction of the two groups were evaluated 3 months postoperatively.RESULTS The WSRS scores of the observation group at 1,3,and 6 months postoperatively were lower than those of the control group(P<0.05).Three months postoperatively,facial fine lines and pores showed obvious improvement and the skin index score was higher in the observation group than in the control group(P<0.05).The compactness of facial contours was better in the observation group than in the control group(P<0.05).In addition,no remarkable differences were noted in the incidence of postoperative adverse reactions such as facial stiffness,facial asymmetry,facial bruising,and facial concavity inequality(P>0.05).CONCLUSION AFG+BTX-A injection is a highly safe,cost-effective,effective,and long-lasting treatment for NLF depression with high esthetic value,which should be promoted in the future.

Negative pressure device-assisted autologous fat grafting: A case report

This report describes a novel technique for improving depressed scars using negative pressure suction-assisted autologous fat grafting.A 35-year-old woman presented with a 20-year history of bilateral central buttock con-cavities,causing aesthetic concerns.To maximize fat graft survival and enhance tissue volume,we implemented intermittent negative pressure suction on the recipient area for one month preoperatively.The patient expressed satisfaction with the cosmetic outcome,and a three-month follow-up confirmed a significantly improved fat graft survival rate.This minimally invasive,cost-effective,and easily reproducible technique offers a promising clinical strategy for treating depressed scars.

Treatment of intractable orbital implant exposure with a large conjunctival defect by secondary insertion of the implant after preceding dermis fat graft

AIM: To report a procedure and results of a two-stage operation to manage intractable extensive orbital implant exposure with a large conjunctival defect which was difficult to treat with dermis fat grafts due to repeated graft necrosis. METHODS: A retrospective chart review of four patients who had extensive orbital implant exposures with large conjunctival defects and had past histories of repeated autologous or preserved dermis graft failures was done. As a first-stage operation, the problematic pre-existing orbital implants were removed and autologous dermis fat grafts alone were performed on the defect area. Four months later, new orbital implants were secondarily inserted after confirmation of graft survival. The size of the conjunctival defects and state of the extraocular muscles were checked preoperatively. Success of the operations and complications were investigated.RESULTS: The mean size of the conjuctival defects was 17.3mm×16.0mm, and the mean time from the initial diagnosis of orbital implant exposure to implant removal and autologous dermis fat graft was 20.8 months. After implant removal and autologous dermis fat graft, no graft necrosis was observed in any patients. Also, implant exposure or fornix shortening was not observed in any patients after new orbital implant insertion. CONCLUSION: The secondary insertion of a new orbital implant after pre-existing implant removal and preceding dermis fat graft is thought to be an another selective management of intractable orbital implant exposure in which dermis fat grafts persistently fail.

Treatment of Temporomandibular Joint (TMJ) Reankylosis with Preservation of the TMJ Prosthesis and Use of Fat Graft: A Case Report and Review of the Literature

We report on a case of TMJ reankylosis (heterotopic bone) following total TMJ alloplastic reconstruction in a 40-year-old Black male. The heterotopic bone was excised following removal of the fossa component. The fossa component was re-inserted, and the periarticular tissue was grafted with fat procured from the abdomen. Patient was placed on an aggressive physiotherapy programme which was monitored for a period of 6 months. He returned for review one year later with a mouth opening of 27 mm. We present also a short review of the literature on heterotopic bone formation. This case is of particular interest in that despite the heterotopic bone around it;the prosthesis was preserved after the bone was removed.

Recurrent Giant Cell Tumor of the Distal End Radius: A Case Report and Surgical Treatment with Wide Resection and Reconstruction with Non-Vascularised Autologous Proximal Fibular Graft

Giant cell tumour of the distal radius is the 3rd most common site after proximal tibia and distal femur. It is locally aggressive and is associated with a high rate of recurrence. Although it is usually treated with various modalities of treatment, wide resection and reconstruction with proximal fibular autograft is most commonly accepted in recurrent cases. The following is a case report of such a case with surgical management.

Effects of radiation and chemotherapy on adipose stem cells: Implications for use in fat grafting in cancer patients

Autologous fat transplantation is a versatile tool in reconstructive surgery.Adipose-derived stem cells(ASCs)increase survival of fat grafts and thus are increasingly used for breast reconstruction in breast cancer patients.However,radiation and/or chemotherapy have been proposed to inhibit soft tissue regeneration in wound healing thus suggesting alteration in stem cell pathways.Therefore,elucidating effects of radiation and chemotherapy on ASCs is critical if one desires to enhance the survival of fat grafts in patients.This review outlines our work evaluating the function and recoverability of ASCs from radiation or chemotherapy patients,focusing specifically on their availability as a source of autologous stem cells for fat grafting and breast reconstruction in cancer patients.Even though evidence suggests radiation and chemotherapy negatively influence ASCs at the cellular level,the efficiency of the isolation and differentiation capacity did not appear influenced in patients after receiving chemotherapy treatment,although fat from radiated patients exhibited significantly altered ASC differentiation into endothelial-like cells.Further,the in vitro growth rates of patient’s ASCs do not differ significantly before or after treatment.Taken together,these studies suggest ASCs as an important new tool for grafting and reconstruction even when radiation and chemotherapy treatment are involved.

Initial Experience of Face Augmentation Using Fat Graft-Platlet Rich Plasma Mix

Plastic surgeons accustomed to use autologous fat grafs for augmentation of soft tissues in the last two decades. The main drawback of fat grafting is unpredictable graft resorption. Several studies have searched for new ways of increasing the viability of the transplanted tissue to overcome this disadvantage. The most recent and promising approach is to mix the fat graft with Platelet-Rich Plasma (PRP) before transplantation. The purpose of this article is to present the initial experience using the autologous fat injection with platlet rich plasma as a method for fascial augmentation.

The reasons for end-to-side coaptation:how does lateral axon sprouting work?

Nerve fibers are attracted by sutureless end-to-side nerve coaptation into the recipient nerve. Opening a window in the epineurium enhances axon attraction and myeliuation. The authors analyze the features of nerve repair by end-to-side coaptation. They highlight the known mechanisms of axon sprouting and different hypotheses of start up signals （presence or absence of an epineurial window, role of Schwann cells, signaling from the distal trunk）. The clinical literature is also presented and differences between experimental and clinical applications are pointed out. The authors propose their point of view and perspectives deriving from recent experimental and clinical experiences.

Treatment of Steroid Induced Lipoatrophy with Structural Fat Grafting

Background: Systemic corticosteroid injections are used to treat a variety of medical conditions. Inaccurate placement of intramuscular injections of corticosteroid can result in local lipoatrophy, and a resultant cosmetic deformity. Objective: Describe the condition, and a simple, reproducible method of correcting the volume deficiency and skin changes associated with steroid induced lipoatrophy Methods: A retrospective chart review was undertaken of all patients treated by the author for steroid induced lipoatrophy between June of 2005 and March of 2011. Results: Structural fat grafting was used to treat 11 patients with steroid induced lipoatrophy during this time period. 10 patients were female and one was male. 9 of the patients had atrophy of the buttock or hip, and 2 had atrophy of the upper extremity. All patients had satisfactory correction of their deformities, and only one of the patients required a second grafting session to achieve an adequate volume for complete correction. Conclusions: Structural fat grafting can eliminate the volume deficiency and skin changes associated with steroid induced lipoatrophy. It is a straightforward, well tolerated method for correcting a problem which can be quite cosmetically deforming.

Current state and exploration of fat grafting

Fat grafting has become one of the most frequently used techniques in plastic and reconstructive surgery.Many studies have focused on optimizing procedures,such as donor site selection,harvesting,processing,and grafting.Representative basic techniques include Coleman’s and“3L3M”techniques.A new technique called compartment-based targeted fat grafting(CTFG)has gradually been established based on anatomical findings of the facial and hand compartments.CTFG achieved precise restoration of the fat volume in the anatomical state.Cell-based fat grafting has introduced new fields involving tissue repair and regeneration,including facial rejuvenation and scar improvement,among others.In this review,we summarize the timeline for the development of fat grafting.

Effect of swirling flow on platelet concentration distribution in small-caliber artificial grafts and end-to-end anastomoses

Platelet concentration near the blood vessel wall is one of the major factors in the adhesion of platelets to the wall.In our previous studies,it was found that swirling flows could suppress platelet adhesion in small-caliber artificial grafts and end-to-end anastomoses.In order to better understand the beneficial effect of the swirling flow,we numerically analyzed the near-wall concentration distribution of platelets in a straight tube and a sudden tubular expansion tube under both swirling flow and normal flow conditions.The numerical models were created based on our previous experimental studies.The simulation results revealed that when compared with the normal flow,the swirling flow could significantly reduce the near-wall concentration of platelets in both the straight tube and the expansion tube.The present numerical study therefore indicates that the reduction in platelet adhesion under swirling flow conditions in small-caliber arterial grafts,or in end-to-end anastomoses as observed in our previous experimental study,was possibly through a mechanism of platelet transport,in which the swirling flow reduced the near-wall concentration of platelets.

Current Status of ADSCs-Enriched Fat Grafts in Plastic Surgery

Autologous fat grafting is an increasingly popular technique in plastic surgery for volume augmentation and rejuvenation.However,the unpredictability of long-term volume retention limits its clinical application.Various animal studies have documented the positive effects of adipose tissue-derived stem cells(ADSCs)on the acceleration of lipofilling.However,the results have been inconsistent,and there is an insufficient number of high-quality clinical studies to formulate evidence-based recommendations for ADSC-enriched fat grafts.Moreover,related technical standards,such as the final count of harvested ADSCs and the enrichment ratio,have not yet been established.This systematic review included all clinical trials on ADSC-enriched fat grafts in plastic surgery from PubMed in the past 10 years,as well as all registered clinical trials on ClinicalTrials.Gov.To examine the current landscape of ADSCs harvest,we summarize the current applications of ADSCs in the field of plastic surgery and discuss the current barriers to universal clinical use.

Patients Returning to Dialysis after Failed Kidney Transplant: How Do They Fare? A Gulf Perspective

An increasing number of failed transplant patients returning to dialysis (FTRD) have been observed with reported worse survival compared to transplant-naive dialysis (TxN) patients. This study aimed to assess outcomes of FTRD vs. matched TxN controls in a Gulf region multi-center trial of 800 HD patients. Similar mortality was seen, likely due to earlier start and better HD adequacy in FTRD. Younger age, less diabetes and living donor transplantation in majority with 27% graft nephrectomy (Nx) might also confer benefits. Subgroup analysis of Nx patients showed more hospitalizations and prior rejection episodes with lower graft survival. The deaths, however, oc-curred only in nonNx group and are likely explained by older age, longer duration on HD, more prevalence of diabetes and CAD. FTRD showed similar survival to TxN. Early intensive HD might account for the benefit. Whether Nx confers advantage is unclear because of the small sample size.

Augmentation mammoplasty with autologous fat grafting

Considering the issues that can accompany prosthetic breast implants,augmentation mammoplasty(AM)with autologous fat grafting(AFG)has attracted growing interest globally,especially in the last two decades,as breast implant-associated anaplastic large cell lymphoma has been increasing in incidence over time.Here,we review the detailed processes of AFG to the breast and the pertinent complications associated with this procedure.This study aims to elucidate the critical points and technique improvements in AM with AFG in recent years,as well as discuss how to decrease complications related to this procedure.Attention was focused on the specific AFG steps,clinical outcomes,and complications to highlight the advantages and disadvantages of the available protocols.

A Novel Composite Skin Graft Technique with Fat Derivatives

Skin grafting,although a relatively classic and well-known technique,still has multiple disadvantages such as secondary contracture of the skin graft,sunken depression,poor elasticity,and color mismatch.Adding adipose tissues significantly improved the graft appearance compared to traditional skin grafting methods.Herein,we report two cases of modified skin graft procedures,both showing positive outcomes.In case 1,a mechanically processed fat-derived product was injected into the lower half of the skin graft area.In case 2,left upper eyelid blepharoplasty was performed,and the orbital fat strip was transferred and placed under the recipient area on the right side.Hair growth was observed only in case 1,whereas the extent of sunken depression was significantly reduced in both cases.Compared to traditional skin grafting methods,adding fat components to the skin graft recipient area improved the appearance and blood supply,together with enhancing the regenerative rate.

Fat Grafting for Rejuvenation and Regeneration with Stromal Vascular Fraction Gel

Lipotransfer has become a powerful regenerative tool,largely because of its cellular components,the stromal vascular fraction(SVF).However,the clinical separation of cells with collagenase is strictly legislated.In 2017,Yao et al.postulated a novel fat-derived product mechanically concentrating SVF cells and an extracellular matrix(ECM)and named it stromal vascular fraction gel(SVF-gel).This review discussed the protocol of SVF-gel and its component as well as its inner structure.The histologic examination and the retention rate after the transplantation of SVF-gel were also rendered.Moreover,we summed up the rejuvenating and regenerative use of SVF-gel and introduced its possible mechanism.

Dermis-fat graft for contracted socket reconstruction in an indigenous black population, Southwestern Nigeria

The purpose of this case series is to report the indications for dermis-fat grafting and the outcome of treatment in orbital soft tissue contraction among patients in a tertiary center. It is a retrospective, consecutive, interventional case series where all patients with orbital soft tissue contraction who had dermis-fat grafting were studied. All nine patients in our series underwent secondary dermis-fat grafting for orbital soft tissue reconstruction. The major cause for contracted socket was surgical eye removal following trauma. Eight of nine patients had no orbital implants inserted at the time of primary eye removal and eight patients have had failed orbital reconstructive procedures. Satisfactory cosmetic results were reported in all patients post-operatively. Dermis-fat grafting for contracted socket reconstruction was found to give satisfactory cosmetic results in our studied population.

Fat Re-Grafting in Facial Asymmetry: A 2-Case Report

Fat redistribution through recycling of previously grafted fat hasn’t been reported. Two facial asymmetry patients are presented with history of fat grafting to the mandibular angle areas. Collected fat from these formerly fat grafted zones and swollen on subsequent extra body weight gain has been re-grafted in the temporal regions for contour enhancement and has retained volume as photographically documented up to 30 months.

Rejuvenation of the centre of the face: a new paradigm. Endoscopic lifting with fat grafting

The ageing process starts in the centre of the face in the periocular region and around the mouth, with a combination of volume loss and tissue descent. It is a logical approach to assess all these problems at once. The combination of minimal incisions vertical endoscopic lifting combined with superficial enhanced fluid fat injection can be an integral approach to facial rejuvenation.
