Abstract
OBJECTIVES The resection of malignant bone tumors of the pelvis causes significant loss of substances making covering procedures difficult. The gluteus maximus pedicled flap allows some reconstructions, but its use in vascular sacrifice is not clearly established. The objective of our study was to study its vascularization in order to assess the possibility of vascular sacrifice during carcinological resection of a pelvic tumor. METHOD We first performed a vascular mapping of the gluteus maximus muscle using 3-dimensional (3D) models from CT angiography in patients with Leriche syndrome. These models were compared to a cadaveric dissection of 2 injected muscles. A second 3D modeling from postoperative scans was performed in patients who had a gluteus maximus flap after pelvic carcinological surgery. RESULTS Ten patients with Leriche syndrome had a 3D model from their scanners. Three distinct arterial systems were identified. Seven patients had a flap from the gluteus maximus muscle, including 3 cases of an Inverted pedicled Hemi Gluteus maximus flap (HGI). According to the modeling, the richness of the vascular network would allow the sacrifice of the superior gluteal pedicle without compromising the viability of this flap. CONCLUSION Our study made it possible to confirm the richness of the vascular network of the gluteus maximus muscle and to consider the theoretical possibility of sacrificing the superior gluteal pedicle without endangering an HGI pedicled muscle flap.

Breast reconstruction is a viable option for older patients. Breast Cancer Res Treat 2021; 191:77-86. [PMID: 34609642 DOI: 10.1007/s10549-021-06389-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Accepted: 09/06/2021] [Indexed: 01/02/2023]
Abstract
PURPOSE Breast cancer is diagnosed at a median age of 62 years in the USA. At the same time, mortality rates for breast cancer continue to decrease, falling by 40% from 1989 to 2016. In the coming decades, the number of elderly patients with breast cancer, potentially seeking reconstruction, is expected to increase. METHODS A retrospective chart review of 309 patients, aged 60 years or older, undergoing immediate or delayed breast reconstruction, was conducted. Patient characteristics, clinical information and major complications requiring reoperation were evaluated. Multivariate analyses identified factors contributing to complications such as BMI, comorbidities, smoking status, history of previous breast conservation therapy (BCT), total expander volume, radiotherapy, and chemotherapy. RESULTS 26.7% of patients had at least one complication requiring reoperation, and 6.9% of patients suffered reconstructive failure. Logistic regression analysis of all patients (n = 309) found a statistically significant relationship between major complication and history of ipsilateral BCT (p = 0.026) and adjuvant chemotherapy (p = 0.005). Logistic regression analysis in patients undergoing tissue expander (TE) reconstruction (n = 215) showed that major complications were related to BMI over 35 kg/m2 (p = 0.04), history of ipsilateral BCT (p = 0.048), and adjuvant chemotherapy (p = 0.033). CONCLUSION Breast reconstruction in women over 60 years old was not independently associated with higher major complication rates in our series.

Gao X, Qin S, Cai H, Wan Q. Comparison of general and aesthetic effects between flapless and flap techniques in dental implantation: a meta-analysis of randomized controlled trials. Int J Implant Dent 2021; 7:100. [PMID: 34595691 PMCID: PMC8484394 DOI: 10.1186/s40729-021-00380-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 08/09/2021] [Indexed: 02/08/2023] Open
Abstract
Background Information about the aesthetic effects of flapless in implant surgeries is scant. Differences of the survival rate (SR) and crestal bone loss (CBL) between the two techniques were also controversial. Thus, this review was aimed to compare the general and aesthetic effects of flapless and flap approaches in implant surgeries. Materials and methods Following the principals of PRISMA, literature databases were searched for the eligible randomized controlled trials (RCTs) comparing the clinical performances of flap and flapless techniques. After that, relevant data of selected studies were pooled and analyzed to compare SR, bleeding on probing (BOP), probing depth (PD), visual analogue scale (VAS), papillae presentation index (PPI), keratinized mucosa (KM) width and CBL between the two techniques. Results Fourteen RCTs were included. No significant difference was found in SR (RR = − 0.01, 95% confidence interval (CI) (− 0.05, 0.04)), BOP (OR = 0.40, 95% CI (0.15, 1.02)), KM width (WMD = − 0.42, 95% CI (− 1.02, 0.17)) between two groups. Subgroup analysis revealed that the difference of CBL was insignificant in two groups (WMD = − 0.13, 95% CI (− 0.63, 0.38)). However, flap techniques would lead more peri-implant PD (WMD = − 0.37, 95% CI (− 0.51, − 0.23)). Subgroup analysis also indicated lower VAS scores in flapless group after 1 day (WMD = − 1.66, 95% CI (− 2.16, − 1.16)) but comparable pain experience after 3 days (WMD = − 0.59, 95% CI (− 1.33, 0.16)). Mean difference of PPI (WMD = 0.32, 95% CI (0.28, 0.35)) between the two groups was significant. Conclusions The flapless procedure showed a superiority in preserving gingival papillae, reducing postoperative pain and peri-implant PD compared to the flap procedure, while exhibiting comparable effects on SR, BOP, KW width changes and CBL. Flapless technique is more recommended at the ideal soft and hard tissue implanting sites.

Expanding indication of free hypothenar flap transfer: Sequential pedicled ulnar palm flap transfer to a relatively large hypothenar flap donor site. J Plast Reconstr Aesthet Surg 2021; 75:332-339. [PMID: 34642064 DOI: 10.1016/j.bjps.2021.08.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 06/11/2021] [Accepted: 08/26/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Free hypothenar flap (HTF) transfer allows sensible soft tissue reconstruction of the fingertip. However, HTF is basically indicated for a relatively small soft tissue defect, as width of an HTF is limited up to approximately 20 mm to allow primary donor site closure. Combined with sequential local flap to an HTF donor site, a larger HTF can be used without the contracture risk. The aim of this study was to evaluate feasibility of free HTF transfer and sequential ulnar palm flap (UPF) transfer (HTF-UPF) for relatively large fingertip reconstructions. METHODS Medical charts of patients who underwent HTF-UPF for fingertip reconstruction were reviewed. An HTF was designed transversely proximal to the proximal palmar crease, and a slightly smaller hemi-spindle-shaped UPF was designed longitudinally on the mid-lateral aspect of the ulnar palm; the UPF was used to close the HTF donor site. Patient and flap characteristics, intra-operative findings, and postoperative results were evaluated. RESULTS Twelve patients with average age of 42.7 years were included. HTF-UPF procedure was performed on 12 fingers. HTF's length/width ranged from 45/20 to 70/40 mm (average, 52.5/32.1 mm). UPF's length/width ranged from 40/20 to 55/30 mm (average, 46.7/24.2 mm). Time for sequential UPF transfer ranged from 3 to 9 min (average, 5.1 min). All HTFs and UPFs survived without flap necrosis or scar contracture. Postoperative sensation was comparable with the contralateral fingertip. CONCLUSIONS HTF-UPF procedure allows relatively large fingertip reconstruction with a minimum risk of HTF donor site contracture.

Abstract
Introduction: The ideal surgical approach to treat craniomaxillofacial skeleton should provide maximum exposure of the facial skeleton, ensure less potential for injury to facial structures and allow for good cosmetic result. Several designs have been described such as hemicoronal, preauricular, lateral eyebrow, and bicoronal approach. Although the bicoronal flap gives superior long-term cosmetic results, it has a few disadvantages. We conducted this study to assess neurosensory disturbances and motor deficit following craniomaxillofacial reconstruction using bicoronal flap. Materials and Methods: A prospective study was carried out in the Department of Oral and Maxillofacial Surgery, North Karnataka, India. Forty patients with craniomaxillofacial trauma requiring fixation of fracture or reconstruction were included in the study. Postoperative neurosensory evaluation is carried out at intervals of 1 week, 1 month, 3 months, and 6 months clinically using mechanoreceptive and nociceptive testing. Results: Among 40 cases, 11 (27.5%) had postoperative paraesthesia affecting the supraorbital region; 9 (22.5%) of them had return of normal sensation within 6 months and 2 (5%) patients became normal after one year. Four patients had unilateral frontalis weakness on the right side for a period of 6 months. Discussion: The bicoronal flap is a preferred approach for access to the craniofacial skeleton and orbit with minimal sensory and motor complications. However, before choosing the same, the advantage of raising such a wide flap should be weighted comparing the benefits and complications.

Abstract
Open pelvic ring fractures can have devastating functional consequences including prolonged disability, chronic pain, infection, and even death. These injuries are uncommon but often involve soft tissue defects. Without early and appropriate coverage, patients are likely to sustain infection, which can be fatal. Here, we present the successful use of a pedicled ALT flap in two patients with soft tissue defects due to open pelvic ring injury. The pedicled ALT flap can be harvested as a composite flap comprising a portion of the skin, fascia, and muscle depending on the defect. Although the ALT flap has often been employed for abdominal wall and abdomino-perineal reconstruction, this is the first case series to report the use of the ALT flap in a subacute traumatic setting for pelvic ring reconstruction.

Abstract
Delayed wound healing in heavily irradiated areas is a serious clinical complication that makes widespread therapeutic use of radiation difficult. Efficient treatment strategies are urgently required for addressing radiation-induced wound failure. Herein, we applied liquid-type nonthermal atmospheric plasma (LTP) to a silk-fibrin (SF) composite gel to investigate whether controlled release of LTP from SF hydrogel not only induced favorable cellular events in an irradiated wound bed but also modulated the SF hydrogel microstructure itself, eventually facilitating the development of a regenerative microenvironment. Scanning electron microscopy and Fourier-transform infrared spectroscopy revealed that LTP modulated the microstructures and chemical bindings of the SF gel. Improved cell viability, morphology, and extracellular matrix depositions by the LTP-treated SF hydrogel were identified with wound-healing assays and immunofluorescence staining. An irradiated random-pattern skin-flap animal model was established in six-week-old C57/BL6 mice. Full-thickness skin was flapped from the dorsum and SF hydrogel was placed underneath the raised skin flap. Postoperative histological analysis of the irradiated random-pattern skin-flap mice model suggested that LTP-treated SF hydrogel much improved wound regeneration and the inflammatory response compared to the SF hydrogel- and sham-treated groups. These results support that LTP-treated SF hydrogel significantly enhanced irradiated wound healing. Cellular and tissue reactions to released LTP from the SF hydrogel were favorable for the regenerative process of the wound; furthermore, mechanochemical properties of the SF gel were improved by LTP.

Abstract
BACKGROUND Degloving injuries represent a challenge in plastic surgery. The aim of this study is to acknowledge the protective effects of hydrogen-rich saline (HRS) solution on a rat hindlimb degloved skin flap. METHODS Twenty-one Sprague-Dawley rats were divided into three groups (control, saline and HRS). Degloving injury model was established, and flaps were sutured back following 5 min of ischemia. The control group did not receive any treatment. The saline group received intraperitoneal physiological saline (10 ml/kg) and the HRS group received intraperitoneal HRS solution (10 ml/kg) postoperatively and daily for 5 days after the operation. Skin samples were obtained for histological, immunohistochemical and biochemical evaluations. RESULTS Inflammation was lower in the HRS compared with saline (p = 0.02) and control (p = 0.004) groups. Edema was lower in the HRS compared with saline (p = 0.02) and control (p = 0.001) groups. Malondialdehyde (MDA) level was lower in the HRS than the control group (p = 0.01). Total antioxidant level was higher in the HRS compared with saline (p = 0.009) and control (p = 0.03) groups. Total oxidant level was lower in the HRS than the control group (p = 0.02). Oxidative stress index was lower in the HRS compared with saline (p = 0.001) and control (p = 0.0001) groups`. Vascular proliferation was higher in the HRS compared with the control group (p = 0.01). CONCLUSION Repeated HRS injections after trauma increased the viability of skin flap in rat degloving injury model by decreasing local tissue injury, due to its antioxidant, anti-inflammatory and angiogenic effects.

Abstract
Wounds resulting from wide local excision of melanoma vary in size and complexity, and require individualized solutions to achieve satisfactory closure. Goals of reconstruction include restoration of form, function, and aesthetics while minimizing donor site morbidity without compromising the effectiveness and safety of oncologic melanoma treatment. Optimal reconstruction relies on an in-depth understanding of the defect, locoregional anatomy and vasculature, available donor tissues, and basic wound healing and surgical principles. This article provides a broad overview of preoperative patient, timing, and wound considerations; various surgical techniques for complex reconstruction throughout the body; and postoperative care and complication management.

Abstract
Coverage of soft tissue defects in the thumb involves a variety of techniques ranging from simple second-intention healing to skin grafting with or without dermal substitutes, to local homodigital or heterodigital flaps and partial toe transfers. The arsenal in terms of skin coverage and especially flaps is very diverse. Our objective is not to make an exhaustive catalog of all the technical possibilities described in the literature, but rather to present in detail the options we have adopted in our daily practice. For each of these techniques, we present the rules for their implementation (anatomical bases, surgical techniques) and their topographical indications.

Abstract
BACKGROUND Flap surgery is frequently used in plastic surgery to close tissue defects. Ischemia-reperfusion (I/R) injury is a significant problem resulting in partial or total flap necrosis. This study aimed to investigate the effect of ceruloplasmin on I/R injury in epigastric island flaps in rats. MATERIAL AND METHOD A total of 32 male Sprague-Dawley rats were divided into four groups with eight rats in each group: The flap was not elevated in Group I; the flap was elevated without ischemia or any application in Group II, after the intraperitoneal saline and ceruloplasmin application the flaps were elevated and ischemia was created in group III-IV, respectively. Bilateral epigastric artery flap was elevated in all groups except Group I. After 6 h of ischemia, the flap was reperfused and inset. Samples were taken from the right and left side of the flap area in other groups at the postoperative 24th h for biochemical analysis (catalase and malondialdehyde-MDA) and the seventh postoperative day for histopathological analysis (Modified Verhofstad score and epidermal thicknesses), respectively. Image analysis for necrosis areas was performed on photos taken on the 7th d. RESULTS Catalase level was significantly higher in Group IV.(0.15 ± 0.04 U/mg protein) (P < 0.05) Necrosis area percentage(14.4% ± 3.3%),MDA(3.6 ± 0.9 nmol/mg protein), edema(3), necrosis(2.75), and polymorphonuclear leukocyte infiltration(2.87) scores were significantly higher in group III.(P < 0.05). Fibroblast proliferation, collagen density (0.25), vascular density (0.25) scores and epidermal thickness (15.68 µm,) was significantly lower in group III. (P < 0.05) CONCLUSIONS: Our study demonstrated that ceruloplasmin application before ischemia reduced I/R injury in epigastric island flaps in rats.

Abstract
Introduction Peptic ulcer perforation (PUP) is one of the most common critical surgical emergencies. The omentum flap is commonly used to cover a PUP. However, the omentum cannot be used in cases of severe peritonitis or previous surgical removal. This is the first study conducted in Vietnam that was designed to analyse the outcomes of patients with PUPs who were treated using the falciform ligament. Method In this study, we retrospectively identified 40 consecutive patients who were treated for PUP at a single high-volume centre in Vietnam from February 2018 to February 2021. Peptic ulcer perforation was measured during diagnostic evaluation based on preoperative imaging, such as X-ray, and CT scan. Patients who had malignancy, laparoscopic surgery, omentopexy and nonoperative treatment were excluded from this research. Results Forty patients were included; the mean age of the patients was 66.3 years (range 33–99 years), and some patients had comorbid disease (57.5%), hypertension (30%), diabetes (10%), cirrhosis (7.5%), and chronic renal failure (7.5%). The PUPs were located in the duodenum (80%), or the pyloric (15%) and prepyloric (5%) regions. The procedures used to treat the patients included duodenostomy (32.5%), gastrojejunostomy (37.5%), and antrum resection (2.5%). The average operative time was 88.6 min (45–180 min), hospital stay was 9.6 days (2–35 days), and oral intake was started at 4.1 days (3–8 days); additionally, the 30-day mortality (17.5%) and incidences of pneumonia (25%), multiorgan failure (15%), acute liver failure (5%), wound infection (7.5%), and ulcer peptic fistula (0%) were assessed. Univariate tests showed that an ASA ≥ III and comorbidities, such as pulmonary complications, liver failure and multiorgan failure, were associated with mortality. The multivariate test showed that multiorgan failure was the only factor related to mortality. Conclusion The falciform ligament can be efficiently used for the closure of a PUP. Although there were no instances of complication with a reperforated peptic ulcer, the mortality rate was slightly highly related to severe comorbidities and postoperative multiorgan failure. Peptic ulcer perforation is one of the most common surgical emergencies with an overall mortality rate is between 1.3% and 20%. Comorbidities, over 70 years old, having surgical therapy after 36 hours, and postoperative complications are associated with mortality. Using falciform ligament to replace the traditional omental patch is interesting, easy applying and efficiently in the closure of PUP. The mortality and complications were still high related to severe comorbidity and multiorgan failure after surgery.

Abstract
PURPOSE To assess the availability, success rate and complications of microvascular iliac crest free flap for reconstruction of mandibular segmental defects. METHODS In this retrospective-descriptive study, we report patients who had undergone segmental mandibular resection for pathologic lesions and received reconstruction with iliac crest microvascular free flap between 2016 and 2019. Clinical and demographic data of all the cases were collected. Success was regarded as complete consolidation of the bone graft in panoramic radiograph. Postoperative complications were defined as major or minor based on the need for intervention. T-test, Kolomogorov_Smirnov, and multivariate analysis were used and the p-value<0.05 was considered to be statistically significant. RESULTS Of all 30 patients, 16 were women and 14 were men with an average age of 27.2 years (range 14-40). Patients were followed for 12-60 month (mean: 38.4). One flap was lost due to unsalvageable venous thrombosis. Six other cases had post-op complications while smoking and diabetes were associated with more complications (P = 0.036). Twenty-three patients received primary reconstruction which was more successful than secondary ones (P = 0.003). Osteogenic sarcoma was associated with greater risk of complications (P < 0.01). CONCLUSIONS The results of this study suggest that iliac crest microvascular free flap serves as a promising option for the reconstruction of mandibular defects, providing excellent contour and acceptable success rate with low donor site morbidity. Future studies will focus on the role of systemic diseases in post-op complications and flap failures.

Abstract
Background The V to Y advancement flap offers an excellent option for reconstructing defects of the lobule and adjacent structures of the external ear. We demonstrate its utility for small defects of the earlobe including those extending to the antitragal and conchal bowl regions. To our knowledge use of this technique for earlobe reconstruction has not been reported. Methods A review of the literature was performed on the use of the V to Y flap for earlobe reconstruction. We then described its use in reconstructing lobular defects in 6 patients. All patients had a non-melanoma skin cancer involving the earlobe. All surgeries were performed under local anesthetic at a tertiary care centre in Halifax, Canada. Defects ranged in size from 1.0 to 1.4 cm. All defects were reconstructed with only a V to Y advancement flap. Patient photographs were taken intra-operatively and post-operatively. For all patients, satisfaction of the final aesthetic result was assessed on a 10 point scale in follow-up at 6 months. Results A review of the literature did not reveal any reports of the V to Y flap used in isolation for lobular reconstruction. At our centre from 2018 to 2020, this method was well tolerated under local anesthetic in 6 patients with non-melanoma skin cancers of the earlobe. All patients reported an aesthetically satisfying result at 6 months with scores ranging between 8 and 10. Scarring in all cases was minimal. Conclusion The V to Y advancement flap is a simple technique for reconstructing small defects of the lobule. This method is technically straight-forward, poses minimal risk to the patient, and in our experience, yields a favourable cosmetic outcome. Graphical abstract ![]()

Abstract
INTRODUCTION Head and neck reconstructive surgery using a flap is increasingly common. Best practices and outcomes for postoperative radiotherapy (poRT) with flaps have not been specified. We aimed to provide consensus recommendations to assist clinical decision-making highlighting areas of uncertainty in the presence of flaps. MATERIAL AND METHODS Radiation, medical, and surgical oncologists were assembled from GORTEC and internationally with the Head and Neck Cancer International Group (HNCIG). The consensus-building approach covered 59 topics across four domains: (1) identification of postoperative tissue changes on imaging for flap delineation, (2) understanding of tumor relapse risks and target volume definitions, (3) functional radiation-induced deterioration, (4) feasibility of flap avoidance. RESULTS Across the 4 domains, international consensus (median score ≥ 7/9) was achieved only for functional deterioration (73.3%); other consensus rates were 55.6% for poRT avoidance of flap structures, 41.2% for flap definition and 11.1% for tumor spread patterns. Radiation-induced flap fibrosis or atrophy and their functional impact was well recognized while flap necrosis was not, suggesting dose-volume adaptation for the former. Flap avoidance was recommended to minimize bone flap osteoradionecrosis but not soft-tissue toxicity. The need for identification (CT planning, fiducials, accurate operative report) and targeting of the junction area at risk between native tissues and flap was well recognized. Experts variably considered flaps as prone to tumor dissemination or not. Discrepancies in rating of 11 items among international reviewing participants are shown. CONCLUSION International GORTEC and HNCIG-endorsed recommendations were generated for the management of flaps in head and neck radiotherapy. Considerable knowledge gaps hinder further consensus, in particular with respect to tumor spread patterns.

Haq A, Singh V, Sharma S. The reverse flow extensor digitorum brevis flap for dorsal foot defects-A single center study. J Plast Reconstr Aesthet Surg 2021; 74:2957-2964. [PMID: 34016573 DOI: 10.1016/j.bjps.2021.03.082] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 12/30/2020] [Accepted: 03/13/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Defects on the dorsum of the foot remain a reconstructive challenge for plastic surgeons. There are very few pedicled flaps that have a reach up to the distal foot and those too with a threat of poor perfusion. Very often distal foot has to be resurfaced with free flap even with small defects. This study describes our experience with the reverse extensor digitorum brevis muscle (EDB) flap for small- to medium-sized defects on the dorsum of the foot. METHODS The study was conducted on 12 patients between February 2018 and March 2020 who presented with defects on the dorsum of the foot. The mean age of the patients was 30.8 years and the mean defect size was 20.17 cm2. The EDB was applied on 10 male and 2 female subjects and resurfaced with a split thickness skin graft. The donor site was closed primarily. RESULTS All flaps survived well. Two patients had small graft loss and 2 partial wound dehiscence of donor site, all of which healed on conservative treatment. Three patients had temporary sensory disturbance which resolved in few weeks. CONCLUSION The reverse EDB flap is a reliable flap for the coverage of small- to medium-sized dorsal foot defects. The flap has the advantage of robust vascularity, expendable muscle with little donor site morbidity, an easy to learn technique, short operating time, and acceptable esthetic outcome, and it can be used as the primary option in cases of small to medium dorsal foot defects.

Use of the supraclavicular artery island flap for reconstruction of maxillofacial defects: a case report and literature review. BMC Surg 2021; 21:193. [PMID: 33853567 PMCID: PMC8048174 DOI: 10.1186/s12893-020-00987-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Accepted: 11/26/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Free flaps are widely used in maxillofacial reconstruction; however, this approach was not feasible in the current case. It was not possible because the free flap method requires microvascular anastomosis expertise, which is difficult, time-consuming and costly. CASE PRESENTATION An 86-year-old woman suffered squamous cell carcinoma on the right side of her face, which resulted in a large soft-tissue defect. Here, we present a case of facial reconstruction from the inferior margin of the jaw to the top of the head. The size of the defect was 18.5 cm × 7.5 cm, which is rare for a patient of this age in the maxillofacial area. We used the supraclavicular artery island flap (SCAIFP) which measured 19.3 cm × 8.3 cm to repair the defect. After the operation, the flap survived without complications. Then, the patient was followed for 10 months and was satisfied with the aesthetic and functional results at the donor and recipient sites following the tumour resection. The tumour did not recur, and facial nerve function was preserved. CONCLUSION Our results provide a new choice for the reconstruction of large defects of the head and face, and expand the potential applications of the SCAIFP.

Innovative adaptation of the "spare tissues concept" applied for olecranon coverage of a severe burn patient: A case report. ANN CHIR PLAST ESTH 2021; 66:346-350. [PMID: 33838956 DOI: 10.1016/j.anplas.2021.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 03/08/2021] [Accepted: 03/10/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND The management of bone exposure in patients with extensive burns could be a challenge due to the lack of healthy tissue. In such cases, it could be interesting to use any still healthy tissue initially destined for amputation and use it to cover up another site. We present the case of a sever burn patient for whom we used the only healthy palmar hand skin to cover an olecranon exposure. CLINICAL CASE DESCRIPTION A 38-year-old man has been admitted in burn victim unit with extensive deep burns on 60% of the total body surface. An exposure of the left olecranon was appeared occurring on a burned area, with absence of healthy local tissues available for coverage. Concomitantly a trans-radial amputation was indicated because of severe digits burns leading to an impossibility to preserve the function of the hand. A palmar skin area was healthy leading to harvested this palmar skin flap pedicled on ulnar vessels. Early post-operative healing was satisfactory and no vascular suffering of the flap has been observed with a total healing at three weeks. CONCLUSION In any patient the spare tissues concept should be keep in mind when amputation is indicated simultaneously with a problematic of loss of substance coverage to a proximity area. In this case of severe burn patient, we used a palmar skin flap pedicled on the ulnar vessels to cover an olecranon exposure.

Abstract
Ulnar tunnel syndrome is the second most common upper-limb peripheral nerve compression syndrome. Recurrence or persistence of symptoms after primary surgery is found in 9.9%-21% of cases. The main cause of failure is peri- and endo-neural fibrosis, and management is difficult and controversial. Revision of nerve neurolysis combined with freestyle adipofascial flap provides nerve decompression and coverage with vascularized tissue, which prevents scar tissue formation around the nerve and restores glide. We performed a preliminary vessel-injected cadaver study. The perforating vessels from the posterior recurrent ulnar artery vascularize the medial adipose and fascial tissues of the elbow, allowing elevation of an adipofascial flap which is able to reach the ulnar nerve. Eight patients with neuropathic ulnar nerve pain in recalcitrant ulnar tunnel syndrome due to peri- and/or endo-neural fibrosis were treated by neurolysis, and the nerve was covered with an ulnar adipofascial flap. All patients were evaluated by percussion test, visual analog scale for pain, electromyography, electroneurography and ultrasound, and were classified according to the McGowan classification as modified by Goldberg. The study was approved by the review board. All patients had good 4-year outcome, with complete return to daily activity, work and sports 4 months after surgery. The results of this novel surgical technique were encouraging, without complications or donor site morbidity. Adipofascial flap combined with neurolysis could be a valid solution in the treatment of recalcitrant ulnar tunnel syndrome.

Revisiting the vascularity of the keratinized gingiva in the maxillary esthetic zone. BMC Oral Health 2021; 21:160. [PMID: 33766000 PMCID: PMC7995803 DOI: 10.1186/s12903-021-01445-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Accepted: 02/18/2021] [Indexed: 02/07/2023] Open
Abstract
Background The active arterial-to-arterial collaterals are a significant factor in the prevention of ischemia and extensive tissue necrosis in the case of arterial blockage of various tissues. The present study investigates the mucogingival vasculature in the maxillary esthetic zone mucosa in human cadavers and functionally evaluates the area, which is supplied by the terminal arterioles, on the individual level. Methods In the human cadaver study, macroscopic arterial analyses of the anterior maxillary vestibule in 7 specimens were scrutinized by latex milk injection. The tracks of the mucosal branches in relation to the mucogingival junction were investigated. In the functional study, individual gingival blood flow (GBF) changes were measured by laser speckle contrast imaging (LSCI) in 31 young subjects with healthy gingiva before and during 30-s compressions. This was conducted with a ball-shaped condenser. The data was analyzed by the linear mixed model. Results The vertically aligned branches of the superior labial artery (SLA) divided into small, slightly deviating sub-branches near the mucogingival junction. These arteries created collateral plexuses and supplied the attached gingiva. The compression of these branches resulted in ischemia coronally with significant individual variation. The ischemia was either apico-mesial, apico-distal, or straight apical to the compression. A significant correlation was found between the ischemic area and the magnitude of the decrease in GBF (r = 0.81, p < 0.001). In males, 77% of the subjects, and 50% of the female subjects had an ischemic response in either region. The horizontal extension of the ischemic area ranged between 0.26 mm and 8.76 mm. Males had significantly higher baseline GBF and larger ischemia than females. At the base of the papilla, significant restoration of GBF was observed during compression in males, but not in females. Conclusion The arcade anastomoses formed by the small arteries in the keratinized gingiva of the upper esthetic zone explain the consequences of vertical incisions. The considerable individual variations in ischemic responses might be the reason for unexpected surgical outcomes in some cases. Furthermore, there is increasing evidence that men have different vascular reactivity and/or regulation of collateral circulation than women, which may affect wound healing.

Lymph-interpositional- flap transfer (LIFT) based on lymph-axiality concept: Simultaneous soft tissue and lymphatic reconstruction without lymph node transfer or lymphatic anastomosis. J Plast Reconstr Aesthet Surg 2021; 74:2604-2612. [PMID: 33867280 DOI: 10.1016/j.bjps.2021.03.014] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 02/01/2021] [Accepted: 03/11/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND Lymphatic system is important to maintain homeostasis. Lymph-axiality concept has been reported, which suggests possibility of lymphatic reconstruction using flap transfer without lymph node or supermicrosurgical lymphatic anastomosis. METHODS Medical charts of 122 free flap reconstruction cases, either with conventional flap transfer (control) or lymph-interpositional-flap transfer (LIFT), for extremity soft tissue defects including lymphatic pathways were reviewed. Lymph vessels' stumps in a flap were placed as close to those in a recipient site as possible under indocyanine green (ICG) lymphography navigation in LIFT group. LIFT group was subdivided into LIFT(+) and LIFT(-) groups; lymph vessels' stumps could be approximated within 2 cm in LIFT(+) group, whereas those could not be in LIFT(-) group. Lymph flow restoration (LFR) and lymphedema development (LED) rates were compared between the groups on postoperative 6 months. RESULTS No flap included lymph node. LFR was observed in 50 cases and LED in 72 cases. LFR rate in LIFT group (n = 75) was significantly higher than that in control group (n = 47) (57.3% vs. 14.9%; P < 0.001). LED rate in LIFT group was significantly lower than that in control group (20.0% vs. 48.9%; P < 0.001). Sub-group analysis showed significantly higher LFR and lower LED rates in LIFT(+) group (n = 44) than those in LIFT(-) group (n = 31; 88.6% vs. 12.9%; P < 0.001, 4.5% vs. 41.9%; P < 0.001). CONCLUSIONS LIFT allows simultaneous soft tissue and lymphatic reconstruction without lymph node transfer or lymphatic anastomosis, which prevents development of secondary lymphedema.

The three-point crossover technique for immediate reconstruction of the umbilicus. Arch Plast Surg 2021; 48:175-178.

Abstract
The umbilicus is an important aesthetic component of the abdomen; therefore, its absence is both cosmetically and psychologically distressing to the patient. However, loss of the umbilicus during abdominal surgical procedures is often unavoidable. Umbilical reconstruction is aimed at obtaining a natural, three-dimensional appearance. We propose a simple method for immediate umbilical reconstruction with good long-term results. This technique was used successfully on a patient who underwent tumor excision. A 49-year-old woman presented with a large mass, measuring 5.8×4.0 cm, on her umbilicus. The mass, an epidermal cyst, developed after laparoscopic uterine myomectomy 5 years earlier. Complete excision of the mass resulted in a large defect, and immediate umbilical reconstruction was planned. Our procedure involved apposing and anchoring two opposing flaps onto the abdominal wall, so that the umbilicus would retain its depth over a long period of time. Negative-pressure wound therapy was applied for 72 hours as a mild compressive dressing. No complications were encountered. The healing process was uneventful and the aesthetic outcome was pleasing; a natural-appearing navel was created. The patient was satisfied with the end result. This technique provides a permanent and sufficient depression for the umbilicus.

Abstract
Transposition scalp flaps are a versatile solution for soft-tissue cover in a multitude of scalp defects. They are frequently used to reconstruct larger skin cancers that involve the outer table of the cranium in addition to covering neurosurgical bony defects and hardware. The transposition flap requires the donor site to be grafted using a split-thickness graft, which results in a secondary wound elsewhere on the body, commonly the lateral thigh. Although quite routine in such surgery, this procedure does require another body area to be prepared and draped. We sought to streamline this procedure with an adjustment to the location of the donor site. In harvesting the graft from the skin of the flap itself, we localised all surgery to one area, which has a number of logistical and patient-care advantages. Our experience has shown significant benefits from this technique and this is now our chosen and recommended donor site for these reconstructions.

Abstract
The birth of rhinoplasty in the West was driven by a great demand for reconstruction of noses destroyed voluntarily or not, post-traumatic or medical. Two men emerge strongly through their work and writings: Gaspare Tagliacozzi for the brachial flap and Joseph Carpue for the frontal flap. Both of them describe a different method but based on the same skin flap principles. But were they really the first? History tells us that other, more anonymous people before them had used these same methods on a large scale but without leaving any conclusive or very significant written trace. The use of flaps or grafts, methods, which are the true pillars of plastic surgery, opened up perspectives much wider than the nose. But history has retained the name of these two men through their writings. If they were not the precursors, they were nevertheless promoters, laying the foundations of modern plastic surgery and promoting the spread of these great principles throughout the world.
