Project description:BackgroundThe radial forearm free flap (RFFF) serves as a workhorse for a variety of reconstructions. Although there are a variety of surgical techniques for donor site closure after RFFF raising, the most common techniques are closure using a split-thickness skin graft (STSG) or a full-thickness skin graft (FTSG). The closure can result in wound complications and function and aesthetic compromise of the forearm and hand. The aim of the planned systematic review and meta-analysis is to compare the wound-related, function-related and aesthetics-related outcome associated with full-thickness skin grafts (FTSG) and split-thickness skin grafts (STSG) in radial forearm free flap (RFFF) donor site closure.MethodsA systematic review and meta-analysis will be conducted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines will be followed. Electronic databases and platforms (PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI)) and clinical trial registries (ClinicalTrials.gov, the German Clinical Trials Register, the ISRCTN registry, the International Clinical Trials Registry Platform) will be searched using predefined search terms until 15 January 2024. A rerun of the search will be carried out within 12 months before publication of the review. Eligible studies should report on the occurrence of donor site complications after raising an RFFF and closure of the defect. Included closure techniques are techniques that use full-thickness skin grafts and split-thickness skin grafts. Excluded techniques for closure are primary wound closure without the use of skin graft. Outcomes are considered wound-, functional-, and aesthetics-related. Studies that will be included are randomized controlled trials (RCTs) and prospective and retrospective comparative cohort studies. Case-control studies, studies without a control group, animal studies and cadaveric studies will be excluded. Screening will be performed in a blinded fashion by two reviewers per study. A third reviewer resolves discrepancies. The risk of bias in the original studies will be assessed using the ROBINS-I and RoB 2 tools. Data synthesis will be done using Review Manager (RevMan) 5.4.1. If appropriate, a meta-analysis will be conducted. Between-study variability will be assessed using the I2 index. If necessary, R will be used. The quality of evidence for outcomes will eventually be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.DiscussionThis study's findings may help us understand both closure techniques' complication rates and may have important implications for developing future guidelines for RFFF donor site management. If available data is limited and several questions remain unanswered, additional comparative studies will be needed.Systematic review registrationThe protocol was developed in line with the PRISMA-P extension for protocols and was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 17 September 2023 (registration number CRD42023351903).

Project description:Skin grafting in nasal reconstruction, long used by dermatologists, can provide superior results and can well be the "go to" procedure for nasal reconstruction. The upper two-thirds of the nose is composed of both flattened, featureless and often thin skin that is well recreated with defect-only full-thickness grafting. Skin grafting for the lower third of the nose has been practiced for years by dermatologists; over the last 4 to 5 years, it has been embraced by plastic surgeons. The patient and donor site selection is critical. Meticulous attention to graft selection, utilization of a no-touch technique during graft harvest and placement of surgical bolsters with through-and-through tacking sutures are essential to ensure 100% graft take and a successful aesthetic result.

Project description:To explore the repairing effect of combination of adipose stem cells (ASCs) and composite scaffolds on CWR, the electrospun Poly 1, 8-octanediol-co-citric acid (POC)-poly-L-lactide acid (PLA) composite scaffolds were prepared, followed by in vitro and in vivo biocompatibility evaluation of the scaffolds. Afterwards, ASCs were seeded on POC-PLA to construct the POC-PLA-ASCs scaffolds, and the POC-PLA, POC-PLA-ASCs, and traditional materials expanded polytetrafluoroethylene (ePTFE) were adopt for CWR in New Zealand white (NZW) rabbit models. As results, the POC-PLA-ASCs patches possessed good biocompatibility as the high proliferation ability of cells surrounding the patches. Rabbits in POC-PLA-ASCs groups showed better pulmonary function, less pleural adhesion, higher degradation rate and more neovascularization when compared with that in other two groups. The results of western blot indicated that POC-PLA-ASCs patches accelerated the expression of VEGF and Collagen I in rabbit models. From the above, our present study demonstrated that POC-PLA material was applied for CWR successfully, and ASCs seeded on the sheets could improve the pleural adhesions and promote the reparation of chest wall defects.

Project description:(1) Background: The reconstruction of cutaneous defects following surgical procedures in the nasal pyramid presents a challenge due to the limited amount of available tissue. In cases of larger defects, skin from adjacent units is used. Traditionally, two-stage surgical flaps have been employed for reconstructing these defects. Tunnelized island flaps allow for the one-stage surgical reconstruction of nasal pyramid defects, using tissue from the forehead or cheek for the flap. (2) Methods: Descriptive retrospective study of 21 consecutive patients who underwent surgery for defects on the nasal pyramid using tunnelized island flaps. (3) Results: Surgical reconstruction was performed in 21 patients with basal cell carcinomas, 14 of them using the melolabial island flap and 7 using the paramedian forehead island flap. In all cases except one, clear histological margins were obtained. Immediate complications were mild and minor. It is worth noting the trapdoor effect complication, which improved over time in most cases, resulting in a satisfactory cosmetic outcome. No tumor recurrences were observed during an average follow-up period of 17.7 months. (4) Conclusions: Tunnelized island flaps allow for single-stage reconstruction of nasal pyramid defects, yielding excellent cosmetic results by utilizing adjacent skin. This procedure demands a certain level of skill but is associated with minimal complications, making it a valuable alternative in reconstructive dermatological surgery.

Project description:The versatility of a pedicled groin flap can be further increased by raising it in a bilobed fashion. This allows the flap to cover both the volar and dorsal surfaces of a hand or forearm defect. A 48-year-old man sustained an avulsion amputation of his right forearm by a rolling machine in a workplace accident. Replantation of the right forearm was performed, and the postoperative course was uneventful. Unfortunately, the wound healing was complicated by circumferential marginal skin necrosis, which was confined to the distal forearm. A bilobed pedicled groin flap was performed for the wound coverage because reconstruction with a free flap would be very risky as the vessels were avulsed from the proximal part of the forearm. A good functional recovery of the hand and fingers was noted at 12 months' follow-up. The advantages of a bilobed pedicle groin flap are that it allows coverage of both the volar and dorsal surfaces at one setting and primary closure of the donor site is possible. Furthermore, a long tube-shaped pedicle in this flap can reduce the patient discomfort and prevent finger stiffness by allowing a range of motion exercise. In conclusion, the bilobed pedicled groin flap is a useful option to cover soft tissue defects involving both the volar and dorsal surfaces over the mid- to distal forearm, especially when the free flap is contraindicated.

Project description:BackgroundThis systematic review compared free anterolateral thigh (ALT) flaps versus pedicled distally based sural artery (DBSA) flaps for reconstruction of soft tissue defects of dorsal foot and ankle in children.MethodsA systematic literature search was performed to identify cases where an ALT or DBSA was used to reconstruct the dorsal foot in children. A total of 19 articles were included in the systematic review.ResultsEighty-three patients underwent an ALT reconstruction and 138 patients underwent a DBSA reconstruction. Patients who had a DBSA were more likely to require grafting of the donor site (P<0.001). The size of ALT flaps was significantly larger than DBSA flaps (P=0.002). Subsequent flap thinning was required in 30% of patients after ALT and 12% of patients after DBSA reconstruction (P<0.001). Complications occurred in 11.6% of DBSA and 8.4% of ALT flaps (8.4%).ConclusionsBoth flaps are valid options in reconstructing pediatric foot and ankle defects. Each flap has advantages and disadvantages as discussed in this review article. In general for larger defects, an ALT flap was used. Flap choice should be based on the size of the defect.

Project description:Both free posterior tibial flap (FPTF) and free radial forearm flap (FRFF) are commonly used for head and neck defects. They have many similarities in embryology, histology, and anatomy, but their advantages and disadvantages in head and neck repair have not been fully recognized. This study aimed to compare the cadaveric anatomy and clinical application of FPTF and FRFF for the reconstruction of head and neck defects after tumor resection. Anatomical dissection was performed on 10 fresh adult cadavers. The general characteristics of both flaps and the sites of recipients and donors were collected. A total of 31 and 25 patients underwent FPTF and FRFF construction, respectively. The patient medical records were assessed to obtain the clinical characteristics. Characteristics of the flap such as size, pedicle length, and clinical process data were collected and compared. The appearance, sensory disturbance, and effect on quality of life and daily activity were evaluated. The posterior tibial artery was present and observed in all patients. The posterior vascular pedicle was longer than the radial artery. There was no difference between the diameters of arteries of FPTF and FRFF; however, the diameters of their veins differed. In terms of flap characteristics, FPTF was significantly larger and had a longer vascular pedicle than FRFF (40.68±11.07 vs. 53.77±29.02 cm2, P=0.03; 8.48±1.66 vs. 11.10±2.39 cm, P=0.00). Patients in the FPTF group had a significantly shorter total hospital stay (FRFF: 26.48±8.33 d; FPTF: 18.58±6.68 d), postoperative hospital stay (FRFF: 17.60±5.53 d; FPTF: 10.94±3.62 d), and flap harvest time (FRFF: 87.00±20.92 min; FPTF: 65.00±17.56 min) than FRFF group. There were far more complications of the donor site in the FRFF group than in the FPTF group. Also, according to the patients' subjective evaluations of the donor site, FPTF was superior to FRFF (P=0.00). FPTF is a reliable alternative to FRFF for head and neck reconstruction. These techniques share similar certain embryogenesis and anatomical characteristics but FPTF possesses unique aesthetic and clinical application advantages.

Project description:Full-thickness deficiency of eyelid tissues can result in coloboma or retraction or both. Here we report our initial experience on the use of auricular skin-cartilage sandwich graft technique for full-thickness eyelid deformities. Five patients (4-32 years) underwent the procedure. Patients with full-thickness eyelid deformity were included. Three patients were operated for large-sized coloboma and two for eyelid retraction. One patient had congenital, and four patients had acquired etiology. The following parameters were specifically assessed: correction of deformity, ocular surface problems, graft status, and epithelization of skin-cartilage graft. All the patients had a good correction of eyelid position, except one patient who had severe eyelid retraction (8 mm) at presentation. None of our patients had corneal erosion/defect, persistent ocular surface redness, or graft loss. The auricular skin-cartilage sandwich graft technique produces optimal results with no graft loss. Advancement of orbicularis muscle in between the auricular skin and cartilage grafts (sandwich technique) is an imperative step that leads to the survival of both grafts.

Project description:Traumatic soft tissue defects of the hand and upper extremities are common and may be challenging to the reconstructive surgeon. Several reconstructive procedures such as use of local, regional, distant, and free flaps have been described. This study aimed to report the techniques, outcomes, and complications of pedicle abdominal flaps in reconstructing hand and upper extremity defects.MethodsIn this retrospective study, we included patients with different traumatic defects in the hand and upper extremities who underwent reconstruction by random pedicle abdominal flaps between 2002 and 2017 at Jordan University Hospital, Jordan. Data were collected and analyzed, and the variables studied included patient age and sex, etiology and size of the defect, complications, outcomes, and the need for further revision procedures. Appropriate statistical analysis was used to examine the potential factors affecting flap survival.ResultsWe included a total of 34 patients with a mean age of 22.2 years, ranging from 1 to 54 years. Finger degloving was seen in approximately half of the patients. Flap survival rate was 85.3%. A small area of defect was the only risk factor that significantly affected the flap failure rate.ConclusionsThin pedicle abdominal flaps are a valid, affordable, and safe option in upper extremity traumatic defects, especially in situations where microsurgical techniques are unavailable or contraindicated. Extra care should be taken when the defect surface area is small.
