Immediate foot reconstruction and revascularization of toes using an interposition superficial circumflex iliac artery perforator flow-through flap: A case report. Microsurgery 2024; 44:e31216.

Abstract
Foot injuries, particularly degloving injuries, can lead to segmental loss of neurovascular structures in the toes, making simultaneous reconstruction of both the foot and toes challenging. This case report presents a technique using the superficial circumflex iliac artery perforator (SCIP) flap for immediate reconstruction of the dorsal foot and revascularization of multiple toes. A 28-year-old man suffered a degloving injury on the dorsum of his foot resulting in a 9 × 6cm skin defect, open fracture dislocations, exposure of tendons, and neurovascular injury, which included a 6-7.5 cm segmental defect of the vessels supplying the first, second, and third toes leaving all three toes ischemic. Immediate reconstruction was performed by harvesting a 12.5 × 5cm SCIP flap including both the superficial and deep branches and incorporating the superficial inferior epigastric vein (SIEV). The SCIP deep branch was used to revascularize the third and second toes and the SIEV vein graft used for the first toe. The patient recovered well, no complications were observed at the 2-year follow-up, preserving all three toes and regaining mobility. The use of the SCIP flap as a flow-through flap provides thin skin flap cover, good vessel caliber size match with digital vessels and reduces the need for vein grafts from distant sites improving surgical efficiency. These attributes make the flow-through interposition SCIP flap an excellent choice for reconstructing foot defects and revascularizing toes. We report this case to demonstrate the utility of the SCIP flap in immediate soft tissue cover and digit revascularization.

Abstract
A perforator is a vessel that travels through muscle and perfuses the skin. Perforator flaps require intramuscular dissection and can be used as pedicled or free flap. With improved understanding of microvasculature, they can be tailored to have multiple skin paddles, multiple components, or shaped to conform to any defect. Reliable perforator flap-based reconstruction is a meticulous microvascular technique, ultimately allowing the surgeon to harvest any flap in a freestyle fashion and transplant to any recipient vessel. New technologies improve the safety and reproducibility of this type of reconstruction.

Subdermal dissection technique for pure skin SCIA and ALT perforator flaps in burns and trauma defects: Clinical experience. Microsurgery 2024; 44:e31189. [PMID: 38798132 DOI: 10.1002/micr.31189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 03/21/2024] [Accepted: 05/01/2024] [Indexed: 05/29/2024]
Abstract
BACKGROUND The pure skin perforator (PSP) flap is gaining popularity for its remarkable thinness. The subdermal dissection technique was recently introduced, allowing for a quicker elevation of a PSP flap. In this report, we present our two-year experience utilizing subdermal dissection for harvesting PSP flaps. METHODS All patients who had undergone PSP flap reconstruction at our hospital from February 2021 to February 2023 were included. Demographic data, intraoperative variables, flap characteristics, and postoperative outcomes were collected. Surgical planning involved locating the perforator using ultrasound and harvesting the flap using the subdermal dissection technique. RESULTS A total of 26 PSP flap reconstructions were conducted on 24 patients aged between 15 and 86 years. The flaps were based on perforators issuing from the superficial circumflex iliac artery in 24 cases, and from the descending branch of the lateral circumflex femoral artery in 2 cases. Flap sizes ranged from 3 × 1.5 cm to 19 × 6 cm, with a mean thickness of 3.48 mm. The average time for flap harvest was 131.92 min. Postoperatively, we observed four cases of partial necrosis, 1 total flap loss, and 2 instances of vascular thrombosis at the anastomosis site. The flaps exhibited good pliability without contracture, and no debulking procedures were required during the follow-up period (minimum 6 months, range 6-24; mean 9.4615). CONCLUSION The subdermal dissection technique is a safe and efficient approach for elevating PSP flaps. Our initial experience with this technique has been encouraging, and it currently serves as our preferred reconstructive option for defects requiring thin reconstruction.

Abstract
BACKGROUND Because of a lack of effective measures to visualize flap vasculature and perfusion, flap fenestration and facial organ fabrication cannot be performed effectively, preventing the transition from two-dimensional coverage to restoration of the three-dimensional (3D) structure of facial organs. This study aimed to evaluate the efficacy of indocyanine green angiography (ICGA) in guiding flap fenestration and facial organ fabrication in total facial restoration. METHODS Ten patients with total facial scarring after burn injury were enrolled in the study. They were treated with preexpanded, prefabricated monoblock flaps for total face restoration. The openings of nostrils and oral and palpebral orifices, together with organ fabrication, were conducted under the guidance of intraoperative ICGA by hemodynamic evaluation of flap perfusion. Postoperative follow-up measures include vascular crisis, infection, flap necrosis, and aesthetic and functional recovery. RESULTS The opening of facial organ orifices was performed at the stage of flap transfer in nine patients. To avoid damaging the major nourishing vessels, the left palpebral orifice was opened 8 days after the flap transfer in one patient, as observed by ICGA. Based on ICGA evaluation, the decision to perform additional vascular anastomosis before flap fenestration was made in six patients. Hemodynamic analysis of flap perfusion after fenestration revealed no significant change. Follow-up showed satisfactory aesthetic recovery and well-restored 3D structures of facial organs. CONCLUSION This pilot study demonstrates how intraoperative ICGA can enhance the safety of flap fenestration, thereby transforming full facial restoration from the two-dimensional to the 3D realm by facilitating facial organ fabrication. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
The upper extremity has unique functional and aesthetic requirements. Reconstruction of upper extremity soft tissue defects should ideally provide coverage for vital structures, facilitate early mobilization, be thin and pliable to match its slim contour, and reestablish sensation. Perforator flaps can be raised on the superficial fascia, which creates a thin and pliable yet durable and supple flap option to match the contour and functional needs of the upper extremity. Comparisons to traditional reconstructive methods should be performed to assess whether these innovations in microsurgical reconstruction of upper extremity defects provide an improved functional and aesthetic benefit over traditional methods.

Abstract
Vascular malformations in the extremities are a common site of occurrence; arteriovenous malformations (AVMs) are the least frequent of all vascular malformations, estimated at 5% to 20%. The first step in management is to perform a thorough clinical examination. Symptoms are assessed, and staging is performed using the Schobinger classification. Next, ultrasonography and contrast-enhanced computed tomography are used to confirm the diagnosis of AVM and to confirm the extent of the malformation. Surgery is the first-line treatment and reconstruction is performed. In cases where surgery is not feasible, embolization and sclerotherapy may be used to alleviate symptoms.

Abstract
Soft tissue defects of the hand may result from trauma, infection, vascular disease, and after resection of tumors. Microsurgery has evolved to a stage where it is relatively commonplace today but procedures such as free flaps still incur significant time, manpower, cost, and material resources. The aim of this article is to articulate the specific situations in hand reconstruction when microsurgery is superior to nonmicrosurgical reconstructive options. The benefits of microsurgical reconstruction include a variety of important metrics, such as improved function, better tissue match, less donor site morbidity, and reduced downtime for the patient.

Abstract
The profunda artery perforator (PAP) flap provides a good option for hand and upper extremity reconstruction. The reliable quality, caliber, and number of perforators in the posteromedial thigh support large flaps with long pedicles. The PAP flap has been widely used for breast reconstruction, although its use in the extremities has been slower to catch on due to the bulk and thickness of the subcutaneous tissue. The authors discuss evolution of thin flaps and our application of the thin and superthin PAP flap for upper extremity reconstruction.

Abstract
INTRODUCTION The superficial circumflex iliac artery perforator flap is based on perforators originated on the superficial circumflex iliac artery. This flap is thin and pliable, of moderate size, and has a concealed donor site. The authors report their experience, innovations, and refinements in both planning and execution, and the outcomes obtained after 101 extremity reconstruction consecutive cases. PATIENTS AND METHODS A total of 101 superficial circumflex iliac artery perforator flaps were prospectively reviewed and followed up for at least one year at Hospital del Trabajador. The flaps were used for both upper (n = 21) and lower limbs (n = 80), planned with computed tomography angiography/augmented reality, and raised above the superficial fascia using a standardized approach. Demographic data, anatomy of the flap, surgical technique, and the results were assessed. RESULTS Average flap size was 90.5 cm2, ranging from 25 to 212 cm2. Total flap loss occurred in 6 flaps (5.9%). Four patients developed complications at the donor site. Debulking surgery was performed in 7 patients (6.9%). The average follow-up period was 850 days (range, 370-1405 days). CONCLUSIONS The superficial circumflex iliac artery perforator flap is versatile, thin, and pliable, suitable for covering even large defects in either the upper or lower extremities, obtaining a shallow contour and optimal esthetics results. The elevation can be standardized, but requires training and proper planning. This is the largest series in a Western country reporting the experience, refinements, and innovation that allows for better results in limb reconstruction.

Abstract
INTRODUCTION Due to 3D defects after resection of hypopharyngeal cancers, free flaps have become as first option for reconstruction and the anterolateral thigh flap (ALT) has been chosen frequently for soft tissue defects. Chimerization of the skin island of the ALT is also possible which can result in reconstruction of multiple defects simultaneously and monitorization of buried flaps. However, ALT can be bulky in some patients. The superthin ALT is well established by some authors especially for extremities but there is no study about the use of this modification in pharyngoesophageal defects. We present our experience of using chimeric-superthin ALT for pharyngoesophageal reconstructions. PATIENTS AND METHODS Between 2019 and 2022, six patients (one female and five male) underwent hypopharyngeal tumor resection and experienced chimeric-superthin ALT flap reconstructions. Patients' ages were ranged between 53 and 71 (mean: 64) years old. The type of tumor was squamous cell carcinoma (SCC) for all patients. Three patients had total and three patients had 75% of pharyngoesophageal defects. Defect size was between 10 × 7 cm and 12 × 8.5 cm (mean: 87.08 cm2 ). All flaps were harvested as 5 mm thickness with two skin perforators. All flaps were divided into two individual skin islands as chimeric fashion. One of the skin islands was used for esophageal reconstruction and the other was used for both flap monitorization and tensionless closure of anterior neck skin. RESULTS Total flap size was between 18 × 9 cm and 21 × 11 cm (mean: 200 cm2 ). In two patients, anastomoses were performed to pectoral branch of thoracoacromial vessels. Neck vessels were chosen as recipient for remaining patients. Wound dehiscence occurred in two patients between the neck skin and monitor island and was re-sutured without any problems. There was no partial or total flap necrosis and all flaps survived. The follow up period was between 4 and 9 months (mean: 5.6). All patients had a successful functional outcome as swallowing. CONCLUSION The superthin-chimeric ALT flap is a useful option when classical ALT is bulky in defects of hypopharyngeal cancer.

Abstract
PURPOSE The conventional abdominal and groin flaps for resurfacing the defect have several disadvantages, including the risk of flap failure due to accidental traction or detachment, immobilization of the arm before division, and aesthetic dissatisfaction because of the flap bulkiness. The aim of this study was to share our experiences with the free lateral thoracic flap and elucidate the optimal timing of division in complex hand reconstruction, which yielded favorable outcomes in terms of both functionality and aesthetics. METHODS This article is a retrospective review of multiple digit resurfacing using free tissue transfer from 2012 to 2022. Patients who underwent two-stage operation including mitten hand creation using superthin thoracodorsal artery perforator (TDAp) free flap and secondary division were included. A flap was elevated over the superficial fascia layer the midportion between the anterior border of the latissimus dorsi and pectoralis major muscles and once the pedicle was found, an outline that matched the defect was created. A process named "pushing with pressure and cutting" was carried out before pedicle ligation until all the superficial fat tissue had been removed except for around the perforator. Two cases (18%) involved defects of the entire fingers reconstructed by TDAp flap with anterolateral thigh flap. Six cases (55%) had a super-thin TDAp flap only. In two cases (18%), non-vascularized iliac bone grafting was required for finger lengthening. One case (9%) was resurfaced with a TDAp chimeric flap including a skin paddle with the serratus anterior muscle. The primary outcome was defined as the survival or failure of the flap, while the secondary outcomes associated complications such as infection and partial flap necrosis. A statistical analysis was not performed due to the size of the case series. RESULTS All 13 flaps survived completely without any complications. Flap dimension ranged from 12 cm × 7 cm to 30 cm × 15 cm. Mitten hand duration prior to division was 41.9 days on average which was essential for the optimal result. During the division procedures, there were nine cases of debulking (82%), six cases of split-thickness skin graft (STSG) (55%), and three cases of Z-plasty performed on the first web space (27%). The mean follow-up period was 20.2 months. Mean Disability of the Arm, Shoulder, and Hand (DASH) Questionnaire score was 10.76. CONCLUSIONS We resurfaced severe soft tissue defects of multiple fingers with thin to super-thin free flaps, mainly TDAp flaps. Surgeons can restore original hand shape using a two-stage reconstructive strategy of mitten hand creation and proper division timing to create a 3-dimensional hand structure, even in severely injured hands with multiple soft tissue defects of the digits.

Abstract
BACKGROUND Elevation in different layers achieving thin flaps are becoming relatively common practice for perforator flaps. Although postreconstruction debulking achieves pleasing aesthetic results and is widely practiced, customized approach during elevation to achieve the ideal thickness will increase efficiency while achieving the best possible aesthetic outcome. Multiple planes for elevation have been reported along with different techniques but it is quite confusing and may lack correspondence to the innate anatomy of the skin and subcutaneous tissue. METHODS This article reviews the different planes of elevation and aims to clarify the definition and classification in accordance to anatomy and present the pros and cons of elevation based on the different layers and provide technical tips for elevation. RESULTS Five different planes of elevation for perforator flaps are identified: subfascial, suprafacial, superthin, ultrathin, and subdermal (pure skin) layers based on experience, literature, and anatomy. CONCLUSION These planes all have their unique properties and challenges. Understanding the benefits and limits along with the technical aspect will allow the surgeon to better apply the perforator flaps.

Abstract
BACKGROUND The expanded forehead flap pedicled with superficial temporal vessel(s) is a common method to treat facial scar deformity. However, local bulkiness and hair retention have limited the use of this flap. METHODS Five cadavers were used for anatomy to confirm the forehead "safety zone." A retrospective study was performed on 15 patients with facial scar deformity who were undergoing the expanded forehead superthin flap (without the expanded capsule, frontalis muscle, and with less hair follicles) pedicled with superficial temporal vessel(s) to transfer and repair the deformity. RESULTS Through cadaver anatomy, the range where the subdermal vascular network laid superficial to the hair follicle level was named the "safety zone," whose average distance between the bilateral penetrating points was 10.2 cm (8.7-11.6 cm). Fifteen patients with facial scar deformity were treated with the superthin flap technique. The trimming size of the safety zone flap was (6-10) × (12-20) cm. The median time of thinning the safety zone was 35 minutes (range, 25-40 minutes). All flaps healed well. The median residual ratio of the hair follicle was 39.8% (29.9%-50.5%). All patients were satisfied with the contour of the flap. CONCLUSION We firstly proposed a concept of forehead safety zone and used the superthin flap without the frontalis muscle and less hair follicles to treat facial scar deformity, and obtained an improved therapeutic effect. We think this is an appealing technique that can manifest facial concave and convex in the fine part, improve compliance of the flap, and reduce the times of laser hair removal.

Abstract
Anatomies of the vascular and lymphatic systems have been vital research topics in reconstructive surgery. Harvey was a pioneer who provided the earliest descriptions of the cutaneous vasculature in the 17th century. The concept of vascular territories of the skin was first described by Manchot. The radiographic injection method in cadavers was developed by Salman, who defined more than 80 vascular territories. The arterial system has been thoroughly investigated with the development of regional and free flaps. The concept of axial and random pattern flaps was introduced by McGregor and Morgan. Manchot's vascular territories were refined by Taylor and Palmer as the angiosome concept. Detailed information about the venous circulation is essential for reconstructive surgeries. The concept of intrinsic and extrinsic venocutaneous vascular systems was introduced by Nakajima and led to the development of the venoadipofascial flap. The importance of venous augmentation in flap survival was emphasized by Chang. The lymphatic system was discovered much later than the arterial and venous systems. Aselli was credited for discovering the lacteal vessels in the 17th century; mercury was popularly used as a contrast agent to distinguish lymphatic vessels for the next three centuries. A radiographic method in cadavers was developed by Suami. Lymphatic imaging devices are constantly upgrading, and photoacoustic imaging was recently introduced for three-dimensional visualization of architecture of superficial layers of the lymphatic and venous systems.

Abstract
Abstract
The principles of nasal reconstruction include the need to reconstruct three tissue layers, the need to restore entire skin aesthetical units, and, possibly, the replacement with like tissues. Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies were applied to two total nasal reconstructions in male patients who underwent rhinectomy for cancer. Three-dimensional (3D) data were obtained from computerized tomography (CT) scan-derived DICOM files (Digital Imaging and Communications in Medicine), this allowed us to design the shape of the reconstructive nose in order to mimic the native nose and to plan dimensions and angles. A custom-made titanium plate was manufactured for the structure and a bi-dimensional template for the forehead flap was printed. The patients underwent a total nasal reconstruction in three layers: local flaps for the lining, custom-made titanium plate for the structure, and expanded forehead flap for the skin. Forehead flap pedicle was divided 3 weeks postoperatively under local anesthesia in an outpatient clinic, as well as further minor refinements. The patients underwent a 6-month post-operative CT scan in order to compare the result to the planned nose. No complications were reported. The superimposition demonstrated a 92% match in case 1 and 95% match in case 2 between the reconstructed nose and the planned one. Forehead flap is still the most favorable option for nasal reconstruction, CAD technology allows to implement the planning and makes the procedure easier; moreover, the use of a CAM plate for the structure allows to reconstruct a nose with the desired naso-frontal angle.Level of evidence: level V, therapeutic study.

Abstract
ABSTRACT In the reconstruction of facial defects, thin and flexible coverage of the defect is desirable for cosmetic reasons. A free flap is 1 possible surgical option; however, a flap containing a fatty layer is bulky. in this study, the authors describe the reconstruction of a facial defect after subtotal parotidectomy for right parotid carcinoma using a superficial circumflex iliac artery pure skin perforator flap, with consideration given to facial contour. The superficial circumflex iliac artery pure skin perforator flap is a viable option to achieve the desired clinical and aesthetic outcome.

Abstract
The patient was a 57-year-old woman who suffered third-degree burns to the dorsal side of her left fingers (non-dominant hand) when it was caught in a press machine heated to 200°C while she was cleaning clothes. At 20 hours after the injury, the necrotic tissue was excised and covered with a preserved subdermal vascular network (PSVN) skin graft, which allowed the patient to regain a very good hand function. Even for severe heat press injuries of the hand, the combination of immediate surgical intervention, a thick skin graft with PSVN, and early rehabilitation from the first postoperative week leads to good functional and cosmetic reconstruction outcomes.

Abstract
INTRODUCTION Published standards for the management of open extremity fractures have improved limb salvage, fracture union, and deep infection rates, but the aesthetic and functional importance of our flap choices has been overlooked. Thin and superthin free flaps exhibit advantages over traditional free flaps in some situations but have seldom been reported in children. The aim of this paper is to present our experience of thin and superthin free flaps in pediatric extremity reconstruction. METHODS Children (≤13 years) who underwent soft tissue reconstruction using a thin and superthin free flap following major extremity trauma are presented. RESULTS Five patients (5 flaps) met the inclusion criteria. The median age was 9 (range 6-13). There were 3 Gustilo IIIB open fractures and 2 multiplanar degloving injuries. The median mangled extremity severity score (MESS) was 4 (range 2-6). The median time from injury to definitive soft tissue closure was 72 h (range 28-120 h). Four anterolateral thigh (ALT) flaps were raised as thin flaps, and 1 superficial circumflex iliac artery perforator (SCIP) was raised as a superthin flap. There was one re-exploration owing to venous congestion, and a second venous anastomosis was performed to enhance flap drainage. The same ALT flap exhibited necrosis at one margin, which was debrided and grafted before discharge. There were no other flap complications. No flap-related secondary surgeries were required. CONCLUSION Thin and superthin free flaps are viable options in pediatric extremity reconstruction. They exhibit excellent aesthetic and functional contouring when a slender fasciocutaneous flap is needed, especially when body habitus renders traditional options unfavorable.

Abstract
Background and Objectives: Prolonged drain stay and lymphorrhea are often problems at the donor site of the superficial circumflex iliac artery perforator (SCIP) flap. This study aimed to introduce a novel technique of the SCIP flap elevation: Deep Fat Saving (DFS) technique. Materials and Methods: Thirty-two patients who underwent the SCIP flap transfer were divided based on the flap-elevated layer: above the deep fascia or the Camper fascia saving the deep fat. The duration of drain stay and the rates of flap survival and donor-site complications were compared between the groups. The inverse probability weighting (IPW) method was conducted to balance confounders. Results: By IPW, two balanced pseudo-populations were created: DFS = 33.9 and Conventional = 31.3. There were no significant differences in the rate of flap survival (DFS: 100% verses Conventional: 95.8%, p = 0.32) and donor site complications (DFS: 2.4% versus Conventional: 1.3%, p = 0.68, respectively). The duration of drain stay was shorter in the DFS group (weighted median: 6 versus 8 days; weighted difference: -1.6 days (95% confidence interval: -2.8 to -0.4), p = 0.01). Conclusions: An SCIP flap can be reliably harvested using the Deep Fat Saving technique.

Abstract
SUMMARY The concept of the perforator has now become a fundamental topic well known in every training program. However, that has not always been so. The mere definition of the word has historically been argued relentlessly; nevertheless, its major derivative, the perforator flap, has become accepted as a basic consideration whenever flaps need be selected. However, this has not been the only spinoff derived from the author's investigations of the perforator, a point that should be stressed in addition to some reiterations of pertinent and perhaps confusing nomenclature that deserve to be reemphasized. Truly, it has been amazing to see how our ideas and innovations arise simultaneously and independently throughout the world of reconstructive surgery. A final plea is made to sustain the future-each of us must continue to contribute our passion and our knowledge to all others by means of that technology now globally so instantaneously available.

Abstract
With advances in anatomical knowledge and technology, increased interest has been directed towards reconstruction with enhanced aesthetic and functional outcomes. A myriad of thinned perforator flap harvest approaches have been developed for this purpose; however, concerns about jeopardizing their vascularity remain. To ensure optimum reconstructive outcome without hampering the flap's microcirculation, it is important to make good use of the existing advanced imaging modalities that can provide clear visualization of perforator branches, particularly in the adipose layer, and an accurate assessment of flap perfusion. Therefore, this review will highlight the imaging modalities that have been utilized for harvesting a thinned perforator flap from these two perspectives, along with future insights into creating both functionally and aesthetically satisfying, yet simultaneously safe, thinned perforator flaps for the best reconstructive outcomes for patients.

Abstract
BACKGROUND Preoperative knowledge of themicrovascular anatomy of a patientmay improve safetyand efficacy and reduce morbidity. Today, with the advancement in technology, ultrasound can provide minute details of the structures within the body, which makes this technology very helpful in preoperative evaluation of the traditional perforator flaps as well as thin, superthin, and pure skin perforator flaps. METHODS In this article, we will describe the design of one of the most popular perforator flaps, the anterolateral thigh (ALT) flap, using high-frequency and ultrahigh-frequency ultrasound technology. RESULTS Ultrasound technology allows to study preoperatively the ALT donor-site and its microvascular anatomy by using different US modalities in order to provide a virtual surgical plan to the operating surgeon. CONCLUSION Ultrasound technology allow to expand preoperative knowledge of flap microvascular anatomy and its course within the subcutaneous tissue up to and within the dermis, allowing to select the best perforator for the given reconstruction and the plane of elevation for thin, superthin and pure skin perforator flap.

Abstract
BACKGROUND The thinned deep inferior epigastric perforator (DIEP) flap branching from the main trunk to the superolateral direction may be useful because of its long vascular pedicle. DIEP flap is used as an axial-pattern adipose flap. The vascular pedicle length of the thinned DIEP flap was investigated using originally developed software. The clinical application of the thinned DIEP flap was verified in a case series. METHODS In 40 patients with enhanced computed tomography (CT) data, the vascular pedicle length of the longest thinned DIEP flap was simulated using the software. A free thinned DIEP flap was used in 10 clinical cases of facial or breast reconstruction. RESULTS In all simulated cases, the vascular pedicle of the DIEP branching to the superolateral direction was the longest, and the vascular pedicle could be lengthened up to 34.8% by dissecting the vessels on the fascia as a vascular pedicle. In all the clinical cases, the reconstruction of a complex form defect or reconstruction requiring a long vascular pedicle could be achieved in one stage without any perioperative complications. The intraclass correlation coefficient between simulated pedicle length and dissected pedicle length was 0.99. CONCLUSION Thinned DIEP flaps with long vascular pedicles could be elevated safely. Multiple adipose or muscle flaps could be combined without complications. The length of the winding vascular pedicle could be measured using imaging data using the software first developed in the present study. This software would be useful in the planning of a thinned DIEP flap and other free flaps.

Abstract
BACKGROUND Reconstruction of Achilles tendon and the overlying tissue defects is a challenging undertaking. The spectrum of available repair methods range from secondary healing to the use of free flaps. The aim of this study was to discuss reconstruction options and to help the surgeon to select reliable approach to achieve favourable outcomes. METHOD In this study, we retrospectively evaluated 14 patients who underwent reconstruction of Achilles region defect between 2016 and 2019 at a single centre. RESULTS Reconstructions were performed with secondary healing (n = 2), negative pressure wound therapy and skin grafting (n = 2), free flaps (n = 6) and local and distant flaps (n = 4). Satisfactory aesthetic and functional outcomes were achieved in all patients. One patient developed partial skin graft loss. Marginal necrosis occurred in one of the local flaps. Wound dehiscence and flap retraction occurred in one of the free (superficial circumflex iliac artery perforator) flaps. One patient undergoing reconstruction with ulnar artery perforator flap developed intraoperative atrial fibrillation; the operation was terminated and reconstruction completed with skin grafting. CONCLUSION Orthoplastic reconstruction should be kept in mind for Achilles tendon defects. The use of special digital imaging techniques facilitates flap surgery and helps minimise the risk of flap complications. Conventional approaches are suitable for shallow small skin lesions. Local flaps are good options for deeper skin defects owing to superior aesthetic outcomes. Super-thin free flaps offer a distinct advantage in skillful hands. The use of multi-content free chimeric flaps for reconstruction of complex defects facilitates better anatomical repair. Cross leg or flow-through flaps may be considered in patients with compromised distal circulation. Selection of the most reliable approach for Achilles reconstruction is a key imperative to achieve favourable outcomes.

Abstract
We studied outcomes of reconstruction of complex upper limb wounds using thinned anterolateral thigh flaps. There were 18 patients with a mean age of 27.5 years. The mean thickness of the flap before and after thinning was 23 mm and 5 mm, respectively. Two patients had partial tip necrosis that was treated conservatively. Aesthetic and functional evaluations were performed using a 5-point Likert scale, QuickDASH score, passive range of motion and power grip at 12 months after surgery. The study showed good results in the aesthetic evaluation by a panel of plastic surgeons (mean score: 19.7) and patient self-assessment (mean score: 18.1). There was a significant correlation between the total scores of the panel and the patients. The mean QuickDASH score was 21, with a high percentage in the middle category 'had a problem but working'. The thinned anterolateral thigh flap is versatile and safe in upper limb reconstruction with good aesthetic and functional results.Level of evidence: IV.

Abstract
BACKGROUND Pure skin perforator and superthin flaps have been reported and are becoming popular, as they allow one-stage thin skin reconstruction even from a thick donor site. However, currently reported elevation procedures use proximal-to-distal dissection requiring free-style perforator selection and primary thinning procedures. With distal-to-proximal dissection using the dermis as a landmark for dissection plane, it is expected that elevation of pure skin perforator or superthin flaps can be simplified. METHODS Patients who underwent pure skin perforator or superthin flap transfers with the subdermal dissection technique were included. Flaps were designed based on location of pure skin perforators visualized on color Doppler ultrasound, and elevated just below the dermis under an operating microscope. Medical charts were reviewed to obtain clinical and intraoperative findings. Characteristics of the patients, flaps, and postoperative courses were evaluated. RESULTS Thirty-six flaps were transferred in 34 patients, all of which were elevated as true perforator flaps (superficial circumflex iliac artery perforator flap in 29 cases, other perforator flaps in seven cases). Mean ± SD flap thickness was 2.24 ± 0.77 mm (range, 1.0 to 4.0 mm). Skin flap size ranged from 3.5 × 2 cm to 27 × 8 cm. Time for flap elevation was 27.4 ± 11.6 minutes. All flaps survived without flap atrophy/contracture 6 months after surgery, except for two cases of partial necrosis. CONCLUSION The subdermal elevation technique allows straightforward and direct elevation of a pure skin perforator or superthin flap within 30 minutes on average without the necessity of primary thinning. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
SUMMARY The updated knowledge of perforasome anatomy and the evolution of microsurgical techniques have enabled surgeons to safely harvest a thin flap. Recently, the anterolateral thigh perforator flap, the current workhorse in soft-tissue reconstruction, has started to be designed and harvested on the superficial fascia, which divides the deep from the superficial fat. This allows elevation of a very thin flap tailored to the defect. Faithful to the ultrathin concept, in an attempt to make flap dissection simpler and safer, the authors describe a revisited harvesting technique of superthin anterolateral thigh perforator flap. This study presents the outlined technique performed in 16 patients with complex soft-tissue defects after trauma or tumor ablation. All of them underwent primary reconstruction using superthin anterolateral thigh perforator free flaps by superficial fascia elevation harvested according to the described surgical procedure. Complications and functional outcomes were assessed. The authors' series of anterolateral thigh perforator superthin flaps demonstrated an overall 100 percent survival rate. Of 16 anterolateral thigh perforators, 12 (75 percent) had no complications and four (25 percent) had minor complications. No major complications such as total flap loss requiring additional salvage surgery were reported. In no case was secondary debulking performed. The superthin anterolateral thigh perforator flap harvested with the described approach was used successfully in microsurgical reconstruction, providing an excellent outer skin cover tailored to the defect. The dissection procedure was safe, quick, simple, and free of major complications. With minimal donor- and recipient-site morbidity, it provided great aesthetic results, avoiding secondary operations. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND A peroneal flap, the boneless version of fibula flap, is considered as the equivalent of radial forearm flap of the lower leg. Because it is thinner than an anterolateral thigh (ALT) flap, the use of a peroneal flap is a viable option for the repair of soft tissue defects when a thin flap could bring about better functional and cosmetic outcomes. In this article, we describe the details of peroneal flap harvest and present our experience with the use of peroneal flaps for head and neck reconstruction. MATERIALS AND METHODS Between 1996 and 2017, a total of 265 peroneal flaps were used to reconstruct a variety of head and neck defects. With the same vascular anatomy and slight modifications to the harvesting technique of a fibula flap, a peroneal flap can be harvested within 1-2 h. All medical records were retrospectively reviewed. RESULTS A peroneal flap can be harvested as different types of chimeric flaps to fit a variety of head and neck defects. The peroneal flap failure rate was 3.4% and the postoperative complication rate was 12.8%. CONCLUSION A peroneal flap might be an alternative option for the reconstruction of head and neck defects.

Abstract
BACKGROUND There has been increasing interest in the superficial circumflex iliac artery perforator (SCIP) flap as a source of thin, pliable soft tissue combined with a favorable donor site. Despite several clinical series from Asia, barriers to adoption include reluctance to perform submillimeter "supermicrosurgery" and the effect of body habitus on flap feasibility. The purpose of this study is to distinguish vascular anatomic characteristics of the SCIP flap in a North American population. METHODS Computed tomography angiography was examined in 84 flaps in healthy prospective renal donor patients from a radiographic database. Descriptive statistics as well as linear regression comparing variables to body mass index (BMI) were performed. RESULTS Mean BMI was 27.1 ± 3.5 kg/m2, while the mean patient age was 47.8 ± 11.4 years. The superficial circumflex iliac artery (SCIA) originated from the common femoral artery in 92% cases, with remainder originating from the profunda femoris. The mean vessel diameter was 1.85 mm at source vessel origin. Distance from skin to source vessel averaged 30.7 mm. Suprascarpal subcutaneous thickness averaged 16.5 mm. The mean distance from Scarpa's fascia to vessel origin was 14.1 mm. Direct three-dimensional distance from vessel origin to pubic tubercle was 50.2 mm. A medial and lateral perforator split off of the SCIA was observed in 38 cases (45%). Significant differences were shown when comparing BMI to skin to source vessel distance (p < 0.001), suprascarpal subcutaneous fat thickness (p < 0.001), and fascial distance to vessel origin (p < 0.001). BMI did not significantly affect vessel diameter. CONCLUSION Despite a significantly higher BMI than many previously published cohorts, the SCIP remains an excellent source of thin and pliable tissue. When dissected closer to the source vessel, a vessel caliber of nearly 2 mm can be achieved, which may obviate the need for "supermicrosurgery" in this population.

Abstract
Another congress of the World Society for Reconstructive Microsurgery (WSRM) this past year in Bologna was magnificent not just for the presentation of so many keynote lectures by the giants of our field nor the novel and innovative ideas shown by those who will someday follow in those footsteps, but by making all of us realize how many capable microsurgeons there are now practically everywhere in this world, doing incredibly important surgical management of challenges that previously were unmet and resulted in sheer devastation for so many of our patients. How much we are the same in our goals, aspirations, and abilities could not be overlooked, but it is amazing how much we also want to learn more together-each relying on the other. To do so, we must not forget our origins as we appropriately plan for the future. All this we philosophized in our WSRM panel on lower extremity reconstruction, while emphasizing on the surface the perforator flap that at the least today has caught everyone's attention. In this overview to follow, we once again tell two stories, starting with the beginnings of the concept of flaps in showing how the nomenclature has evolved over time according to our various surgical manipulations. Often overlooked, though, is a parallel timeline by the anatomists who have better elucidated the circulation to these flaps, where it will become obvious that often long ago the existence of perforators was recognized by them long before known by the surgeons. At least today, these two paths have at least temporarily intersected. Our pursuit of the "perforator" in the perforator skin flap has come full circle, following the course of the history of the flap itself-a pursuit of excellence.

Abstract
Reconstruction of the lower extremity is considered a major challenge due to frequent bone exposure and the absence of local tissue redundancy, as well as often due to the presence of vascular insufficiency. Many surgeons have preferred free flaps especially for reconstructing the more distal lower limb defects until the evolution of pedicled perforator flaps and propeller flaps in particular provided a like-with-like reconstruction of the lower extremity without affecting the main vessels of the limb or the underlying muscles, and without the risk of any microanastomosis especially in patients with multiple comorbidities. Perforator-pedicled propeller flaps as local flaps in the lower extremity are best suited for small- and medium-sized defects with minimal donor-site morbidity, regardless of the cause of the defect. Any of the three source vessels of the leg can provide reliable perforators for propeller flap coverage of the distal leg and foot. The three main risk factors that are relative contraindications may be advanced age, diabetes mellitus, and atherosclerotic peripheral vascular disease.

Abstract
The superficial inferior epigastric artery (SIEA) flap is widely used in the repair of large soft tissue defects of the extremities and in breast reconstruction. Because of the high fat content of the abdomen, it has been less used for glossectomy reconstruction. Here we present a series of seven patients who each underwent reconstruction with a thin SIEA flap after resection of the tongue. There were six men and one woman (mean age 48, range 24-66 years). All patients underwent preoperative computed tomographic (CT) angiography, and colour Doppler ultrasound (US) was used to select and map the most suitable SIEA. The flap was raised above the Scarpa's layer while adjusted the plane of dissection according to the specific needs for bulk in each case. All the flaps survived; one flap required a secondary anastomosis because of a venous anastomotic embolus. The size of flap used was 5.0cm×6.0cm - 7.0cm×9.0cm, and the flap was 0.8cm-1.4cm thick. The functional outcome was evaluated at 6 - 18 months follow up, when speech and swallowing were both good in all cases. The dissection above the pubic symphysis is an important refinement of the SIEA flap, and we conclude that the thin SIEA flap is a good choice for reconstruction after excision of cancer of the tongue.

Effective Secondary Reconstruction of Refractory Urethrocutaneous Fistula after Metoidioplasty Using Folded Superficial Circumflex Iliac Artery Perforator Flap. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e2716.

Abstract
Supplemental Digital Content is available in the text. One of the primary goals of penile reconstruction for female-to-male transsexuals is to enable voiding while standing. Metoidioplasty represents a viable option, but it is associated with a high rate of postoperative fistula formation and recurrence, which affects the aesthetic and functional outcomes. Subsequent surgical repair using scarred and inadequate local tissue may contribute to fistula recurrence. The folded superficial circumflex iliac artery perforator (SCIP) island flap offers sufficient well-vascularized tissue and skin envelope for the reconstruction of the urethra and outer skin after failed metoidioplasty. The SCIP flap can be elevated as a hairless thin flap, making it useful in urethral reconstruction even when it is folded. We describe a case of a 44-year-old female-to-male transsexual patient who developed a refractory urethrocutaneous fistula after metoidioplasty. Surgical repairs were attempted using local tissue 4 times without success. The patient presented to our hospital, and we performed urethral reconstruction using a folded, pedicled SCIP flap for both urethra and skin augmentation. The postoperative course was uneventful, with satisfactory functional results and low donor-site morbidity. No fistula recurrence was observed during the 2 years of follow-up. This novel procedure offers a viable alternative technique for refractory urethrocutaneous fistula repair.

Abstract
Supplemental Digital Content is available in the text. Treating burn scar contractures is challenging. Although free flap transfer is an effective tool for hand reconstruction, free flaps are often bulky, causing functional disturbance and poor cosmetic appearance. Secondary debulking operations are required, resulting in a prolonged total treatment period and delayed return to daily life and work for the patient. Therefore, 1-stage reconstruction using a thin and pliable flap is ideal. In this report, we present the superthin TDAP flap as an option for the reconstruction of postburn palmar contracture. During TDAP flap elevation, the thoracodorsal artery perforator was identified and traced distally until its penetration into the dermis. Subsequently, the subdermal tissue was removed and a uniformly superthin TDAP flap was elevated. Postoperatively, early functional recovery was achieved with excellent palmar contour and texture. No revision surgery was required and no recurrence of contractures occurred during the 6-month follow-up. This procedure is useful in elevating a superthin TDAP flap and is a feasible option for the reconstruction of working surfaces, such as the palm.

Abstract
With advancement of microsurgical techniques, supermicrosurgery has been developed. Supermicrosurgery allows manipulation (dissection and anastomosis) of vessels and nerves with an external diameter of 0.5 mm or smaller. Because quality of life of cancer survivors is becoming a major issue, less invasive and functionally-better oncological reconstruction using supermicrosurgical techniques attracts attention. Conventional free flap reconstruction usually sacrifices major vessels and muscle functions, whereas supermicrosurgical free flaps can be transferred from anywhere using innominate vessels without sacrifice of major vessel/muscle. Since a 0.1-0.5 mm vessel can be anastomosed, patient-oriented least invasive reconstruction can be accomplished with supermicrosurgery. Another important technique is lymphatic anastomosis. Only with supermicrosurgery, lymph vessels can be securely anastomosed, because lymph vessel diameter is usually smaller than 0.5 mm. With clinical application of lymphatic supermicrosurgery, various least invasive lymphatic reconstruction has become possible. Lymphatic reconstruction plays an important role in prevention and treatment of lymphatic diseases following oncologic surgery such as lymphedema, lymphorrhea, and lymphocyst. With supermicrosurgery, various tissues such as skin/fat, fascia, bone, tendon, ligament, muscle, and nerves can be used in combination to reconstruct complicated defects; including 3-dimensional inset with multi-component tissue transfer.

Abstract
Thin flaps, a modification of traditional flaps that minimize the need for debulking and revision, offer unique advantages in the field of lower limb reconstruction. Advances in the field of microsurgery have made this streamlined method of reconstruction a viable solution for soft tissue coverage in patients with both trauma and nonhealing wounds. Better understanding of anatomy has allowed for flap harvest above the fascia level and the Scarpal plane. These modifications allow for flap transfer with thicknesses more comparable to the native anatomy of the lower leg, ankle, and foot. Flap survival is comparable to traditional techniques with greater potential for improved patient-centered outcomes.

Abstract
OBJECTIVE To review the historical origin and development of thin flap and flap thinning technique. METHODS A wide range of domestic and foreign literatures on thin flaps and flap thinning technique were reviewed. The background, definition, methods, problems, challenges, and future development of thin flap and flap thinning technique were summarized and analysed. RESULTS Thin flap and flap thinning technique play an important role in the development of flap surgery, leading flap surgery towards a more rational and refined direction. CONCLUSION Thin flap and flap thinning technique are still hot topics in the future. With the development of thin flap and flap thinning technique, clinicians will have more "free" choices.

J Plast Reconstr Aesthet Surg 2019; 72:1150-1156. [PMID: 30952589 DOI: 10.1016/j.bjps.2019.03.014] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2018] [Revised: 01/16/2019] [Accepted: 03/10/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND Indocyanine green angiography (ICGA) is slowly replacing conventional methods of evaluating perfusion during flap surgery. Microcirculatory changes during flap elevation create a marked state of hypoperfusion intraoperatively leading to ICGA underestimation of tissue viability and consequent resection of viable tissue. We propose a novel method of flap warming to induce maximum vasodilation before performing ICGA to increase accuracy in assessing perfusion. METHODS Submental flaps harvested on a single perforator were created in 8 pigs. ICG angiography was performed in the intraoperative phase (ICGA-C), after inducing maximum vasodilatation by warming the flap at 42 °C (ICGA-W) and at 24H postoperative (ICGA-24). By setting a fluorescence threshold of 33% as indicative of necrosis, the flap surface deemed viable by ICGA was measured for ICGAC, ICGAW and ICGA24. The results were then compared to the actual flap survival observed clinically at 7 days. RESULTS The mean of ICG-C predicted flap survival (FS-C = 49.17%) is 12.97% lower than the mean of actual flap survival on postoperative day 7 (FS = 62.14%). The mean difference between ICG-W and ICG-24 predicted flap survival (FS-W and FS-24) and actual flap survival in the postoperative day 7 (FS) is lower, 3.13% and 2.15%, respectively. Average perfusion recovery over 24 h was 10.83% (FS-24-FS-C). CONCLUSIONS Conventional intraoperative ICGA underestimated perfusion in all cases. Warming the flap intraoperatively and achieving maximum vasodilation mitigates the effects of vasoconstriction and mimics the microcirculatory environment encountered at 24 h. Performing angiography after induced vasodilation improves ICGA assessment of flap perfusion.

Abstract
Supermicrosurgery is sophisticated microsurgical technique, which allows dissection and anastomosis of blood/lymphatic vessels and nerves with external diameter of 0.5 mm or smaller. With increasing attention to quality of life of cancer survivors, less invasive and functionally-better oncological reconstruction using supermicrosurgical techniques is warranted. Unlike conventional free flap reconstruction, supermicrosurgical free flaps can be elevated from anywhere using innominate vessels with diameter of 0.1 mm or larger, allowing patient-oriented least invasive reconstruction. Since lymphatic vessels can be anastomosed, lymphatic reconstruction is possible with supermicrosurgery, which plays an important role in management of cancer-related lymphedema. Supermicrosurgeons can harvest vascularized tissues such as skin, fat, fascia, tendon, ligament, bone, muscle, and nerve separately, and reconstruct complicated defects with three-dimensionally-inset multi-component tissue transfer.
