UNASSIGNED: Propeller perforator flaps (PPFs) have increased in popularity due to the freedom in design and ability to cover a variety of defects without sacrificing the major vessels. Present reports of PPFs for upper limb reconstruction have not provided guidance for hand reconstruction, specifically. This study aims to review the current literature and evaluate techniques for use of PPFs in hand reconstruction.
UNASSIGNED: A comprehensive literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for articles published from 1991 to 2021. The database search was queried for records using appropriate Medical Subject Headings (MeSH) terms. Studies reporting PPFs were limited to English language and excluded lower extremity or upper extremity reconstruction not specific to defects in the hand or digits. Study characteristics, patient demographics, indications, preoperative testing, flap characteristics, flap survival, and complication rates were collected.
UNASSIGNED: Out of the initial 1,348 citations yielded, 71 underwent full-text review. Ultimately, 25 unique citations were included encompassing 12 retrospective reviews (48%), 3 prospective cohort studies (10%), and 10 case series (40%). In review, 525 patients underwent reconstruction with a total of 613 propeller flaps performed to repair defects of the hand, digits, or both with use of 18 unique flap types. Overall flap survival was 97.8%. Acute wounds accounted for 72.9% of performed reconstructions. The mean flap coverage was 14.7 cm2. Complications occurred in 19.8% of cases, with venous congestion and partial flap necrosis occurring in 5.5 and 6.5% of cases, respectively, leading to a flap failure rate of 2.1%.
UNASSIGNED: PPFs are a reliable option for hand or digital reconstruction, allowing surgeons to cover a variety of defects without sacrificing local vasculature. Despite nearly a 20% reported complication rate, nearly all flaps with venous congestion and partial flap necrosis included in these articles resolved without the need for secondary intervention, retaining an excellent overall flap survival.

OBJECTIVE: To examine the role of bowel diversion and reconstructive surgeries in managing Fournier\'s gangrene (FG) to facilitate multidisciplinary collaboration between urologists, colorectal and plastic surgery teams.
METHODS: A review of the literature was conducted using the databases Medline, Embase, PubMed in June 2023. The review included studies that evaluated the outcomes of FG following reconstructive surgeries or diverting colostomies.
RESULTS: The existing evidence suggests that bowel diversion and colostomy formation could reduce the need for further debridement, shorten the time to wound healing, and facilitate skin graft or flap uptake in patients with FG. Additionally, the psychological impact of a stoma was shown not to be a major concern for patients. However, stoma carries a risk of perioperative complications and therefore may prolong the length of hospital stay. In reviewing the evidence for reconstruction in FG, large and deep defects seem to benefit from skin grafts or flaps. Noticeably, burial of testicles in thigh pockets has grown out of favour due to concerns regarding the thermoregulation of the testicles and the psychological impact on patients.
CONCLUSIONS: The use of bowel diversion and reconstructive surgeries in managing FG is case dependent. Therefore, it is important to have close discussions with colorectal and plastic surgery teams when managing FG.

UNASSIGNED: Mastectomies have a significant socio-psychological impact, motivating patients to undergo breast reconstruction. Initially, silicone implants were used to reconstruct the breast. However, breast implants have been the subject of successive crises throughout the years. Indeed, rupture, silicone bleeding, and capsular contracture remain topical. In 2019, the BIOCELL textured breast implants was banned and recalled due to the discovery of the breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). More recently, the breast implant illness has been depicted in the media. To cope with these issues and to respond to some patients\' expectations for a natural reconstruction, plastic surgeons have developed autogenous solutions for breast reconstruction. Since Taylor\'s research on angiosomes, the development of the microsurgery and more recently fat grafting, autogenous breast reconstruction has known a tremendous expansion. Autologous breast reconstruction allows a more natural feeling and texture. This narrative review aims to provide to the readers a comprehensive and updated evidence-based overview of state of the art about autologous breast reconstruction after total mastectomy.
UNASSIGNED: We conducted a narrative review of the literature searching for papers published between January 2010 and December 2022. The MeSH terms with different combinations were used to identify articles for inclusion. After screening article titles and abstracts independently by three authors, 66 papers were included in this review.
UNASSIGNED: In this review, the authors describe and discuss the different autogenous techniques in breast reconstruction.
UNASSIGNED: Autologous reconstructions provide very satisfactory, durable, and reliable results with relatively low complication rates. Deep inferior epigastric perforator (DIEP) flaps, latissimus dorsi flaps and autologous fat grafting are the most common type of autogenous breast reconstructions.

The choice of reconstruction type is of utmost importance in treating breast cancer. There are two major reconstructive pathways in this group of patients: autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR). The aim of this systematic review and meta-analysis was to assess and compare IBR vs. ABR.
A review of studies reporting the differences between the procedures was performed. The MEDLINE/PubMed, ScienceDirect, EMBASE, BIOSIS, SciELO, Scopus, and Web of Science databases were thoroughly searched in September 2021. The data concerning group characteristics, BREAST-Q scores, complication rates, length of stay (LOS), and costs were extracted. The Cochrane risk-of-bias tool was used for randomized studies, while Newcastle-Ottawa Quality Assessment for Cohort Studies was used for other types of research.
Our meta-analysis included 32 studies (n = 55,455). We observed significantly better outcomes following ABR when it comes to esthetic satisfaction (mean difference [MD] -8.51; 95% confidence interval [CI] -10.70, -6.33; p<0.001) and satisfaction with the entire reconstructive treatment (MD -6.56; 95% CI -9.97, -3.14; p<0.001). Both methods appeared to be comparable in terms of safety, while the complication rates varied insignificantly between the groups (odds ratio [OR] 1.06; 95% CI 0.71, 1.59; p = 0.76). ABR seems to be correlated with significantly higher costs (standard mean difference [SMD] -0.69; 95% CI -1.21, -0.17; p = 0.010).
The results obtained from this evidence-based study will improve the understanding of the different clinical pathways that patients can be assigned to. The study emphasized the advantages and disadvantages of both methods.

UNASSIGNED: Although a natural phenomenon, aging is a degenerative condition that promotes cellular malfunction and subsequent organ and body dysfunction. According to the World Health Organization, the elderly are the fastest growing age group worldwide. A 2012 population report stated that 43.1 million adults of 65 years or older lived in the United States, which is expected to jump to 83.7 million in 2050, placing an additional burden on an already stretched health-care network. Elderly patients broadly impact our health-care system, as reported in a 2014 wound report. 8.2 million patients were diagnosed with at least one type of wound, with patients 75 years or older making up most of the diagnoses. Aging affects all stages of the wound healing cascade. Although wound healing is downregulated in the elderly, scarce information exists regarding the effects of aging and flap survival in this group. Therefore, this study aims to report the impact of age on the survival of flaps in murine models. We hypothesize that increased aged animals will have decreased flap survival.
UNASSIGNED: A systematic review was performed on February 1, 2022, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. We searched for full-text articles written in English, consisting of experimental murine models that compared flap survival between aged and young animals, in the following databases: PubMed, Scopus, CINAHL, and Web of Science. The terms \"mice\" OR \"rats\" AND \"surgical flaps\" AND \"aging\" guided our search. Models affected by chronic diseases were excluded from the study.
UNASSIGNED: Out of the 208 articles found by our search, seven were included according to our inclusion and exclusion criteria. Five studies used rats as experimental models, while the remaining two used mice. Local flaps were done in five studies, and two performed free flaps, transferring them from young and aged animals to young controls. Five articles reported lower flap survival in elder groups when exposed to ischemic insults. Three papers reported a deficiency in angiogenesis, vasculogenesis, and vascular reactivity as plausible causes for lack of survival, with one author correlating and verifying their results in human subjects. Although one article reported a lack of statistical power, they perceived a trend similar to the previous studies. Finally, one article reported inconclusive and variable results.
UNASSIGNED: Evidence suggests that a lack of angiogenic and vasculogenic response in conjunction with decreased vascular reactivity are responsible for the diminished survival of flaps in the elder. Therapeutic means to boost the angiogenic, vasculogenic, and vascular reactivity response to improve patient outcomes require further research to understand the time course and mechanisms of flap survival in the elderly.
UNASSIGNED: All humans will feel the effects of aging one way or another. However, we can all agree that aging affects our basic biological processes, which negatively affects macroscopic appearance. One of the essential aspects downregulated in the elderly is their ability to respond to tissue injury and hypoxia, creating non-favorable circumstances for wound healing. Furthermore, to manage these non-healing wounds, flaps are raised to create a covering for these defects. However, age also impacts the ability of these flaps to survive, augmenting the problem and entering a vicious circle. To improve outcomes, we must focus our future research on understanding the basic principles of how aging affects the survival of flaps in elderly population.

BACKGROUND: Deep sternal wound infections are rare but severe complications after median sternotomy and can be managed with sternal reconstruction. The use of pectoralis major flap (PMF) has traditionally been the first-line approach for flap reconstruction but the advantage in patients\' survival when compared to the omental flap (OF) transposition is still not clear. We performed a study-level meta-analysis evaluating the association of the type of flap on postoperative outcomes.
METHODS: A systematic search of the literature was performed to identify all studies comparing the postoperative outcomes of PMF versus OF for sternal reconstruction. The primary outcome was postoperative mortality. Secondary outcomes were the occurrence of sepsis, pneumonia, operative time, and length of stay. Binary outcomes were pooled using an inverse variance method and reported as odds ratio (OR) with corresponding 95% confidence interval (CI). Continuous outcomes were pooled using an inverse variance method and reported as standardized mean difference (SMD) with corresponding 95% CI.
RESULTS: Four studies with a total of 528 patients were included in the analysis. Overall, 443 patients had PMF reconstruction, and 85 patients had OF reconstruction. Baseline characteristics were similar in both groups. There were no statistically significant differences between PMF patients and OF patients in mortality (OR 0.6 [0.16; 2.17]; p = .09), sepsis (OR 1.1 [0.49; 2.47]; p = .43), pneumonia (OR 0.72 [0.18; 2.8]; p = .11), length of stay (SMD -0.59 [-2.03; 0.85]; p < .01), and operative time (SMD 0.08 [-1.21; 1.57]; p < .01).
CONCLUSIONS: Our analysis found no association between the type of flap and postoperative mortality, the incidence of pneumonia, sepsis, operation time, and length of stay.

Native skin flap necrosis is a potentially devastating complication following skin-sparing or nipple-sparing mastectomy with a reported incidence of as high as 30%. Treatment depends on the depth and extent of tissue necrosis and can range from dressings to surgical debridement and further reconstruction. This can have implications on patient physical and psychological wellbeing as well as cost of treatment. This study aims to identify and appraise cost-effective non-surgical adjuncts for the prevention of native skin flap necrosis.
A systematic review was performed using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement and structured around existing recommended guidelines. A search of MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature and ClinicalTrials.gov was performed with the medical subject headings \'mastectomy\' and \'flap necrosis\'. After exclusion, 12 articles were selected for review and analysed.
A total of 8439 mastectomies were performed on 7895 patients. Preventative non-surgical adjuncts that demonstrated statistically significant reduction in mastectomy flap necrosis included topical nitroglycerin ointment (P = 0.000), closed-Incision negative pressure wound therapy (P = 0.000), topical dimethylsulfoxide ointment (P = 0.03), oral cilostazol (P = 0.032), and local heat pre-conditioning (P = 0.047).
This study identifies multiple adjuncts that may aid in preventing mastectomy skin flap necrosis, especially in high-risk patients. Further studies could aim to define standardized protocols and compare the various adjuncts in different circumstances.

The commonest cause of microvascular free flap failure is thrombosis at the anastomosis. Pharmacological antithrombotic therapies have been used to mitigate this risk, but they carry the risk of bleeding and haematoma formation. To justify any intervention, it is necessary to evaluate the benefits and balance of risks. This meta-analysis aims to quantify the value of systemic anticoagulation during head and neck free tissue reconstruction. We performed a systematic review on the impact of additional prophylactic antithrombotic therapy on head and neck (H&N) free tissue transfer (on top and above the use of low molecular weight heparin to prevent deep vein thrombosis). We carried a PRISMA-guided literature review, following registration with PROSPERO. All studies analysing the possible impact of prophylactic anticoagulants on free flap surgery in the head and neck were eligible. The primary outcome was perioperative free flap complications (perioperative thrombosis, partial or total free flap failure, thrombo-embolic events, or re-exploration of anastomosis). Secondary outcomes included haematoma formation or bleeding complications requiring further intervention. We identified eight eligible studies out of 454. These included 3531 free flaps for H&N reconstruction. None of the assessed interventions demonstrated a statistically significant improvement in free flap outcomes. Accumulative analysis of all anti-coagulated groups demonstrated an increased relative risk of free flap complications [RR 1.54 (0.73-3.23)] compared to control albeit not statistically significant (p = 0.25). Pooled analysis from the included studies showed that the prophylactic use of therapeutic doses of anticoagulants significantly (p = 0.003) increased the risk of haematoma and bleeding requiring intervention [RR 2.98 (1.47-6.07)], without reducing the risk of free flap failure. Additional anticoagulation does not reduce the incidence of free flap thrombosis and failure. Unfractionated heparin (UFH) consistently increased the risk of free flap complications. The use of additional anticoagulation as \'prophylaxis\' in the perioperative setting, increases the risk of haematoma and bleeding.

Numerous reconstructive techniques for nasal defects following skin cancer removal have been described; however, the literature lacks a comprehensive systematic review. Our objective was to systematically review nasal reconstruction methods after tumor removal, correlate the use of specific techniques to the nasal subunits involved, assess the quality of the available evidence, and set the stage for future research on this topic. Eight databases were searched for studies published in English from January 2004 to December 2018 containing repair data for nasal defects following Mohs or excision for four or more subjects. Recorded data included author specialties, study design, subject number, demographics, defect characteristics, procedure type, reconstructive methods, outcome measures, and complications. One-hundred and eleven studies were included. Study types included case series (73%), observational cohort studies (25%), and clinical trials (2%). Most authors were dermatologic surgeons (61%). Resection was most commonly performed via Mohs (82%). Flaps (42%), linear closures (28%) and grafts (25%) were most utilized for reconstruction. In Zones I and II, transposition flaps were the most common followed by advancement flaps. In Zone III, full thickness skin grafts were the most common repair. Most studies were case series or small cohort studies, representing low level evidence. Flaps are the most common method described in the literature for nasal reconstruction. The overall quality of the evidence available on this topic is low.

UNASSIGNED: The fasciocutaneous (FC) flap or the axial flap consists of skin, subcutaneous tissue, and deep fascia. In the literature today, there is no evidence suggesting that either surgery is superior to the other in terms of outcome and complications. Reviews in the literature currently compare the outcomes of skin closure after Orthopedic surgeries. The meta-analysis aims to compare the clinical outcomes, complication rates, need for re-surgery, and donor site morbidity between the AF flaps and FC flaps. A null hypothesis that stated inferior outcomes of FC flaps along with more complication rates over AF flaps was kept at the start of the study.
UNASSIGNED: Cochrane Library, PubMed, Embase were searched until December 2020. The review included all original studies which compared the outcomes or complications between FC and AF flaps. The quality of studies was assessed using the Minors score.
UNASSIGNED: A total of 7 original studies with AF and FC flap procedures of which 136 underwent FC flap and 212 underwent AF flap. The pooled data meta-analysis and the subgroup analysis of these studies found no standardized protocol for reporting the outcomes or the cosmetic outcome of the flap surgery. The adipofascial group showed overall shorter operative time, less bulky flap and ability to wear footwear. Also the complications did not differ in both groups with respect to flap loss, complication following surgery, wound dehiscence, wound closure, donor site complications.
UNASSIGNED: The current meta-analysis reveals that there is no added benefit of using AF flaps over the FC flaps. The rates of partial or total flap necrosis along with donor site morbidities and successful wound closure and overall complication rates were similar between the two groups. However, there is evidence to support the superiority of AF flaps over the FC variety with respect to ease of wearing footwear and a less bulky flap.
UNASSIGNED: Level 1 Systematic review and meta-analysis.
