Abstract
Objective: To explore the repair methods of complex facial defect wounds involving paranasal sinuses and their clinical effectiveness. Methods: A retrospective observational study was conducted. From January 2020 to May 2022, 5 patients admitted to the Department of Burns and Plastic Surgery of Xiangya Hospital of Central South University and 4 patients admitted to the Department of Burns and Plastic Surgery of Chenzhou First People's Hospital with complex facial defect wounds involving paranasal sinuses met the inclusion criteria, including 6 males and 3 females, aged 35-69 years, including 4 patients with titanium mesh exposure combined with paranasal sinuses injury and 5 patients with tumor involving paranasal sinuses. After an adequate assessment of the damage by a multiple discipline team, titanium mesh removal, paranasal sinus debridement, and paranasal sinus mucosa removal were performed in patients with exposed titanium mesh, and radical tumor resection was performed in patients with tumors, with postoperative skin and soft tissue defects areas of 5.0 cm×2.5 cm to 18.0 cm×7.0 cm, anterior paranasal sinus wall defects/absence areas of 3 cm×2 cm to 6 cm×4 cm, and sinus cavity depths of 1 to 4 cm. Depending on the perforator course of the descending branch of the lateral circumflex femoral artery, the anterolateral femoral chimeric flap or anterolateral femoral myocutaneous flap (with flap area of 9 cm×4 cm to 19 cm×8 cm, muscle size of 5 cm×3 cm×3 cm to 11 cm×6 cm×3 cm) was transplanted to repair the defect, and the donor site wound was sutured directly. The type of tissue flap transplanted, the blood vessel of the recipient area, and the vascular anastomosis way during the operation, the recovery of the donor and recipient areas and the occurrence of complications after operation were observed. The appearance and blood supply of the recipient area and the recurrence of ulcers and tumors were followed up. Results: The anterolateral femoral myocutaneous flap transplantation was performed in 6 patients, and the anterolateral femoral chimeric flap transplantation was performed in 3 patients. The blood vessels in recipient areas were facial arteries and veins in 3 cases and superficial temporal arteries and veins in 6 cases. The superficial temporal arteries and veins were bridged with blood vessels in tissue flaps by flow-through way in 2 patients, and end-to-end anastomosis of blood vessels in donor and recipient areas was performed in 7 patients. After operation, all the tissue flaps survived, and the facial defect wounds were well repaired without cerebrospinal fluid leakage or paranasal sinus secretion leakage, no intracranial infection occurred, and the wounds in donor areas were healed well. Follow-up of 6-35 months after operation showed that all the patients had good blood supply in the recipient area, and the shape was acceptable; 4 patients with exposed titanium mesh had no recurrence of ulceration, and 5 patients with tumor had no local tumor recurrence or metastasis. Conclusions: Based on an adequate assessment of the extent of paranasal sinuses involved in the facial wound and the nature of the defect, good clinical effects can be achieved by using the anterolateral femoral muscle flap or the anterolateral femoral chimeric flap transplantation to repair complex facial defect wounds with open paranasal sinuses.

Abstract
Objective To investigate the accuracy and reliability of augmented reality (AR) technique in locating the perforating vessels of the posterior tibial artery during the repair of soft tissue defects of the lower limbs with the posterior tibial artery perforator flap. Methods Between June 2019 and June 2022, the posterior tibial artery perforator flap was used to repair the skin and soft tissue defects around the ankle in 10 cases. There were 7 males and 3 females with an average age of 53.7 years (mean, 33-69 years). The injury was caused by traffic accident in 5 cases, bruising by heavy weight in 4 cases, and machine injury in 1 case. The size of wound ranged from 5 cm×3 cm to 14 cm×7 cm. The interval between injury and operation was 7-24 days (mean, 12.8 days). The CT angiography of lower limbs before operation was performed and the data was used to reconstruct the three-dimensional images of perforating vessels and bones with Mimics software. The above images were projected and superimposed on the surface of the affected limb using AR technology, and the skin flap was designed and resected with precise positioning. The size of the flap ranged from 6 cm×4 cm to 15 cm×8 cm. The donor site was sutured directly or repaired with skin graft. Results The 1-4 perforator branches of posterior tibial artery (mean, 3.4 perforator branches) in 10 patients were located by AR technique before operation. The location of perforator vessels during operation was basically consistent with that of AR before operation. The distance between the two locations ranged from 0 to 16 mm, with an average of 12.2 mm. The flap was successfully harvested and repaired according to the preoperative design. Nine flaps survived without vascular crisis. The local infection of skin graft occurred in 2 cases and the necrosis of the distal edge of the flap in 1 case, which healed after dressing change. The other skin grafts survived, and the incisions healed by first intention. All patients were followed up 6-12 months, with an average of 10.3 months. The flap was soft without obvious scar hyperplasia and contracture. At last follow-up, according to the American Orthopedic Foot and Ankle Association (AOFAS) score, the ankle function was excellent in 8 cases, good in 1 case, and poor in 1 case. Conclusion AR technique can be used to determine the location of perforator vessels in the preoperative planning of the posterior tibial artery perforator flap, which can reduce the risk of flap necrosis, and the operation is simple.

Abstract
Objective:To analyze the clinical effect of free posterior lateral peroneal artery perforator flap of lower leg in repairing postoperative defect of oropharyngeal carcinoma. Methods:Thirty-six patients with oropharyngeal carcinoma admitted to the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Bengbu Medical College from June 2016 to June 2019 were analyzed and followed up, eighteen patients were treated with free posterior lateral peroneal artery perforator flap of the lower leg to repair the postoperative defects(experimental group), and eighteen patients were treated with free forearm flap(control group). The survival rate of the transplanted flap, the wound stageⅠhealing rate and average hospitalization time were compared between the two groups. Kaplan-Meier method was used to calculate the 1-year and 3-year survival rates of patients after operation, and log-rank test was used to compare the difference between the survival curves of the two groups; The recovery of swallowing and palatopharyngeal closure function of patients in the two groups at 3, 6, 12 and 18 months after operation was calculated and statistically analyzed through the water swallow test and the air blowing method. Results:There was one case of skin flap necrosis in both the experimental group and the control group, and the survival rate was 94.4%. The wound stageⅠhealing rate in the surgical area was 94.4% in both groups. The wound healing rates of the donor area in the experimental group and the control group were 100.0% and 94.4% respectively. The average hospitalization time of the experimental group and the control group was 16.9 days and 17.2 days, respectively, with no significant difference (P>0.05). The overall survival rates of all patients at 1-year and 3-year were 91.2% and 66.5% respectively; The 1-year and 3-year survival rates of the experimental group and the control group were 94.1%, 69.3% and 88.2%, 63.7%, respectively, and there was no significant difference between the two groups (P>0.05). The 1-year and 3-year survival rates of P16+ and P16 - patients were 100.0%, 80.0% and 85.7%, 64.3%, respectively, and there was no significant difference between the two groups (P>0.05). There was no significant difference in the evaluation of swallowing and velopharyngeal closure function between the two groups at 3 and 6 months after operation (P>0.05), but there was a significant difference at 12 and 18 months after operation (P<0.05). Conclusion:The anatomic position of the perforating vessels of the free posterior lateral peroneal artery perforator flap of the lower leg is constant, and it can be prepared into single leaf, multi leaf, chimeric and other flaps according to the tissue defect space. And the concealed supply area can be directly drawn to suture. At the same time, the skin flap has strong plasticity. Therefore, the skin flap can be used as a common skin flap to repair the defects after the operation of oropharyngeal carcinoma.

Abstract
Objective: To explore the clinical effects of proximal ulnar artery perforator flap combined with iliac bone graft in the reconstruction of subtotal thumb or finger defects. Methods: A retrospective observational study was conducted. From August 2016 to August 2019, 7 patients with thumb or finger defects caused by mechanical damage who met the inclusion criteria were admitted to Ruihua Affiliated Hospital of Soochow University, including 6 males and 1 female, aged 46 to 58 years. Their length of fingers was repaired with iliac bone, with length of 2.0 to 3.0 cm. After the bone graft, the skin defect area of the affected finger ranged from 2.8 cm×2.2 cm to 6.0 cm×3.2 cm. Then the free proximal ulnar artery perforator flap with area of 3.0 cm×2.4 cm to 6.5 cm×3.5 cm was used to cover the wounds. The wounds in donor sites of iliac crest and flap were directly sutured. The survival of flap in one week post surgery and the donor site wound healing in 2 weeks post surgery were observed, respectively. During the follow-up, the appearance and sensory function of the affected finger, bone healing, and scar hypertrophy of wound in the donor site were observed and evaluated. At the last follow-up, the functional recovery of the affected finger was evaluated with trial standard for the evaluation of functions of the upper limbs of the Hand Surgery Society of Chinese Medical Association. Results: In one week post surgery, all the flaps survived. In 2 weeks post surgery, the iliac bone and the wounds in forearm donor site healed. During the follow-up of 5 to 13 months, the flap was good in appearance, without obvious pigmentation; the sensory recovery reached level S2 in 5 patients and S0 in 2 patients; all the grafted iliac bones were bony union without obvious resorption; the wounds in donor site healed well, with only mild scar formation. At the last follow-up, the shape of the reconstructed finger was close to the healthy finger, and the functional evaluation results were excellent in 3 cases and good in 4 cases. Conclusions: The use of proximal ulnar artery perforator flap combined with iliac bone graft to reconstruct subtotal thumb or finger can partially restore part of the appearance and function, with less damage to the donor site. It is a good choice for patients who have low expectations of appearance and function for the reconstructed finger.

Abstract
OBJECTIVE To investigate the effectiveness of perforator propeller flap of lower limb in the treatment of foot and ankle defect in children. METHODS The clinical data of 28 children with foot and ankle defect treated with perforator propeller flap of lower limb between January 2018 and January 2021 were retrospectively analyzed. There were 18 boys and 10 girls with an average age of 7.3 years (range, 6-14 years). There were 8 cases of traffic accident injury and 20 cases of chronic infection wound. The disease duration was 2-4 months, with an average of 2.8 months. After thorough debridement, the residual wound size ranged from 5 cm×4 cm to 9 cm×5 cm. Repairing was performed after 7-28 days of the infection in control. According to the location, size, and shape of the wound, the perforating vessels were located by ultrasonic Doppler, and the perforator propeller flap (area ranged from 6 cm×5 cm to 11 cm×6 cm) was designed and harvested to repair the wound. Flap transfer combined with free split-thickness skin graft covered the wound in 2 cases. The donor site was sutured directly (22 cases) or repaired with skin graft (6 cases). RESULTS Twenty-six flaps survived, of which 20 cases were in primary healing, and 6 cases had epidermal necrosis at the end of small paddle, which healed after dressing change. Necrosis occurred in 2 cases due to venous crisis which healed after anterolateral femoral flap free transplantation. Primary wound healing was achieved in donor site. All 28 children were followed up 6-24 months (mean, 10.5 months). The texture, shape, and motor function of the lower limb was satisfactory. At last follow-up, the American Orthopaedic Foot and Ankle Association (AOFAS) score was 89.8±8.0, which was significantly different from the preoperative score (79.6±10.4) ( t=-11.205, P<0.001); 20 cases were excellent, 6 cases were good, and 2 cases were poor, and the excellent and good rate was 92.8%. CONCLUSION The perforator propeller flap of lower limb in children has its own characteristics. It is a reliable method to repair the foot and ankle defect in children.

The concept of "whole perforator system" in the lateral thoracic region for latissimus dorsi muscle-preserving large flaps: An anatomical study and case series. PLoS One 2021; 16:e0256962. [PMID: 34473793 PMCID: PMC8412279 DOI: 10.1371/journal.pone.0256962] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 08/19/2021] [Indexed: 11/23/2022] Open
Abstract
Background Previous studies have reported on the abundant cutaneous perforating blood vessels around the latissimus dorsi (LD) lateral border, such as a thoracodorsal artery perforator (TDAP) of septocutaneous type (TDAP-sc) and muscle-perforating type (TDAP-mp), or the lateral thoracic artery perforator (LTAP). These perforators have been clinically utilized for flap elevation; however, there have been few studies that accurately examined all the cutaneous perforators (TDAP-sc, TDAP-mp, LTAP) around the LD lateral border. Here, we propose a new “whole perforator system” (WPS) concept in the lateral thoracic region and a methodology that enables elevating large flaps with reliable perfusion in a muscle-preserving manner. Methods We first performed an anatomical study that verified the number and perforating points of all perforators around the LD lateral border using the results of dynamic contrast-enhanced magnetic resonance imaging of patients with breast cancer. Following the anatomical evaluation, we performed large muscle-preserving flap transfer that contained all of the perforators around the LD lateral border in an actual clinical setting. Results A total of 175 latissimus dorsi from 98 patients were included. The mean number of perforators (TDAP-sc + TDAP-mp + LTAP) per side was 4.51±1.44 (2–9); TDAP-sc was present in 57.1% (100/175) of cases, and TDAP-mp in 76.6% (134/175); the TDAP total prevalence rate (TDAP-sc + TDAP-mp) was 96.0% (168/175). The LTAP existence rate was 94.3% (165/175). Distance from the axillary artery to the TDAP-sc was 148.7±56.3 mm, which was significantly proximal to the TDAP-mp (183.8±54.2 mm) and LTAP (172.2±81.3 mm). Conclusion The lateral thoracic region has an abundant cutaneous perforator system derived from the descending branch of the thoracodorsal and lateral thoracic arteries. Clinical application of the lateral thoracic WPS flap is promising, with a large survival area even with muscle-preserving procedures and requiring a relatively simple procedure.

Abstract
BACKGROUND Vascularized omental lymphatic transplant (VOLT) is an increasingly popular treatment of extremity lymphedema given its promising donor site. While the success of VOLT in the treatment of lymphedema has been reported previously, several questions remain. AIM To further elucidate appropriate use of VOLT in the treatment of lymphedema, specifically addressing patient selection, harvest technique, and operative methods. METHODS AND RESULTS A systematic review of VOLT for upper extremity lymphedema was performed. Of 115 yield studies, seven were included for analysis based on inclusion and exclusion criteria. Included studies demonstrated significant reductions in extremity circumference/volume (average volume reduction, 22.7%-39.5%) as well as subjective improvements using patient-reported outcomes. Though studies are heterogenous and limited, when analyzed in aggregate, suggest the efficacy of VOLT in lymphedema treatment. CONCLUSION This is the largest systematic review of VOLT to date. VOLT continues to show promise as a safe and efficacious surgical intervention for lymphedema in the upper extremity. Further studies are warranted to more definitively identify patients for whom this technique is appropriate as well as ideal harvest and inset technique.

Abstract
Since its initial description in 1996 by Yii and Niranjan, the internal pudendal perforator flap (also known as the Singapore flap, the gluteal fold flap, and the lotus petal flap) has become a workhorse in perineal soft tissue reconstruction. In 2001, Hashimoto described the presence of three to five perforators in the perineal anogenital triangle. The ischial tuberosity has thus become a useful anatomic landmark for the safe boundary of medial dissection during flap elevation, in order to avoid damaging the perforator vessels. The objective of the present study was to evaluate the perforators' positions within the anogenital triangle by using color Doppler ultrasound. In a study of 15 subjects in the lithotomy position, we identified a total of 24 perforator vessels with a diameter greater than 5 mm. We noted the vessels' positions using orthonormal measurements, according to the distance from the midline and the distance on a straight line between the two ischial tuberosities (i.e. consistent bony anatomic landmarks that are independent of the patient's height and body mass index). The mean distance between the ischial tuberosity and the internal pudendal perforator was 27.3 mm. Based on our present results, we consider that routine ultrasound identification and dissection of the perforators is not always required before pudendal flap harvesting. This decreases the operating time and simplifies the flap harvesting procedure.

Abstract
INTRODUCTION Vascularized proximal fibular epiphyseal transfer is a reconstruction method for joints and growing bones. The authors investigated the vascular supply of the proximal fibula, including skin perforators, for suitability in creating an osteocutaneous flap. METHODS Twenty fresh cadaveric knees were studied using computed tomographic angiography combined with anatomical dissection. Three-dimensional angiography was used to develop an overview, and multiplanar two-dimension angiography was used for detailed data collection. Anatomical dissection verified by angiography was used to locate skin perforators of the proximal part of the anterior tibial artery. RESULTS Proximal fibular bone perforators from the anterior tibial artery were found to arise either from the anterior tibial recurrent artery, the posterior tibial recurrent artery or the circumflex fibular artery in every specimen (100%), whereas perforators from the inferolateral genicular artery met those criteria in 12 of 18 specimens (66.7%). In the proximal half of 20 anterior tibial arteries, 129 skin perforators with a diameter larger than 0.5 mm were found. There were 54 potential septocutaneous skin perforators between the extensor digitorum longus and the peroneus longus muscles (EDL/PL), and 18 between the extensor digitorum longus and the tibialis anterior muscles (TA/EDL). Skin perforators from the inferolateral genicular artery emerging from the posterolateral corner of the knee had a diameter of < 0.5 mm. CONCLUSION Based on this cadaveric study, the reverse flow anterior tibial artery pedicle and the EDL/PL or TA/EDL skin perforators can be considered as options for osteocutaneous proximal fibular transfers.

Abstract
BACKGROUND The forearm is a common donor site, providing thin, pliable workhorse flaps for head and neck reconstruction. There are no prospective studies comparing the donor-site morbidity of the radial forearm flap to the ulnar artery perforator flap. METHODS All patients undergoing forearm free flaps were included for analysis and followed for a minimum of 1 year. Grip strength, sensation to light touch, temperature sensation, and wound healing were assessed. RESULTS A total of 98 patients were enrolled (radial forearm flap, n = 50; ulnar artery perforator flap, n = 48). There were three osteocutaneous radial forearm flaps performed. The donor site was closed primarily in one radial forearm flap patient and four ulnar artery perforator flap patients. The majority of donor sites were resurfaced with full-thickness skin grafts (radial forearm flap, n = 40; ulnar artery perforator flap, n = 44), and the remaining were closed with split-thickness skin grafts. Average grip strength compared to baseline measured at 1, 3, 6, and 12 months after surgery demonstrated no significant differences. All patients returned to baseline sensation to light touch with no long-term sensory deficits at 1 year. No patients suffered significant changes in temperature sensation or cold intolerance. Seven patients suffered partial skin graft loss (radial forearm flap, n = 5; ulnar artery perforator flap, n = 2); all of them healed secondarily with local wound care. There were no flap losses in the study. CONCLUSIONS The radial forearm and ulnar artery perforator flaps are equivalent in terms of success and donor-site morbidity. Selection of flap should be based on need for pedicle length, flap bulk, concerns with radial or ulnar dominance, and surgeon comfort. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, II.

Abstract
BACKGROUND Patients with breast cancer-related lymphedema can be treated with a simultaneous deep inferior epigastric perforator (DIEP) flap, vascularized inguinal lymph node transfer, and lymphovenous anastomosis for aesthetic breast reconstruction and lymphedema in one operation. METHODS The authors performed a comparison of prospectively followed patients who underwent free flap breast reconstruction with vascularized inguinal lymph node transfer and anastomosis to a retrospective cohort of patients who underwent free flap breast reconstruction with vascularized inguinal lymph node transfer alone. RESULTS Thirty-three patients underwent DIEP flap reconstruction with vascularized inguinal lymph node transfer and lymphovenous anastomosis, and 21 received a free flap with lymph node transfer alone. There were no significant differences in demographics, adjuvant chemotherapy, or radiation therapy. The average number of nodes removed was also equivalent (21.2 versus 21.4 nodes). Two anastomoses per patient, on average, were performed (range, one to four) in the combined cohort, and all patients (100 percent) reported a subjective improvement in symptoms, compared with 81.0 percent of patients undergoing only lymph node transfer (p = 0.019). Perometer measurements demonstrated a significant reduction between the groups at early time points [3 months, 40.7 percent versus 20.0 percent (p = 0.037); 6 months, 57.0 percent versus 44.5 percent (p = 0.043)]; however, the difference was not statistically significant at 12 months (60.4 percent versus 57.8 percent; p = 0.43). CONCLUSION This is the first prospective study demonstrating the safety and efficacy of a combined DIEP flap with vascularized inguinal lymph node transfer and lymphovenous anastomosis, which may be superior to lymph node transfer alone.

Abstract
BACKGROUND With advances in technology and technique, the goal of microvascular breast reconstruction has transitioned from flap success to minimizing complications and maximizing aesthetic outcome and efficiency. In an effort to evaluate efficiency, the authors implemented a rigorous process analysis in their practice to evaluate deep inferior epigastric perforator (DIEP) flap breast reconstruction. METHODS A prospective implementation of process analysis was instituted on 147 DIEP flaps. The eight critical maneuvers for a DIEP flap are (1) skin to perforator identification, (2) perforator decision making, (3) perforator dissection, (4) pedicle dissection, (5) flap harvest, (6) preparation for microsurgery, (7) venous anastomosis, and (8) arterial anastomosis. Surgeons with variable experiences (faculty, faculty with senior resident/fellow, and supervised chief resident) used these eight steps to perform DIEP flap reconstruction. The outcomes and time of each maneuver were tracked. RESULTS The total flap harvest time among the three groups was 54.8 minutes for faculty surgeons, 98.3 minutes for senior resident/fellow working with faculty, and 178.8 minutes for supervised chief resident (p < 0.001). The largest difference was seen in perforator dissection. Increasing the number of perforators resulted in longer flap harvest times. Perforator location did not have an impact on times, but harvesting multiple rows took longer for less experienced surgeons. Body mass index and flap weight did not have an impact on time. CONCLUSIONS The authors share their experience using process analysis for DIEP flap reconstruction. They defined eight critical maneuvers to maximize efficiency and safety. By communicating efficient processes and integrating them into the workflow of a given operation, surgeons can continue to improve throughout the arc of their careers.

Abstract
OBJECTIVE To study the effectiveness of digital technique in repairing of heel wound with peroneal artery perforator propeller flap. METHODS Between March 2016 and March 2019, the heel wounds of 31 patients were repaired with the peroneal artery perforator propeller flaps. There were 21 males and 10 females, with an average age of 36 years (range, 12-53 years). Seventeen patients were admitted to hospital in emergency after trauma, the time from injury to admission was 6.0-12.5 hours, with an average of 8.5 hours; 14 patients were chronic infectious wounds and ulcer. The wound area ranged from 5 cm×4 cm to 12 cm×8 cm. Before flap repair, CT angiography (CTA) data of lower extremity was imported into Mimics19.0 software and three-dimensional reconstruction of peroneal artery perforator and skin model, accurate location of perforator, accurate design of perforator flap, and simulated operation according to the defect range and location were obtained. RESULTS The origin and course of peroneal artery perforator, the position of perforator, the diameter of perforator, and the maximum length of the naked perforator were determined based on the three-dimensional model. There was no significant difference in locating point of perforator, diameter of perforator, maximum length of naked perforator between the pre- and intra-operative measurements ( P>0.05). The position of the lower perforator of the peroneal artery were on the posterolateral lateral ankle tip (5-10 cm) in 31 cases. The total incidence of perforating branches within 10 cm on the tip of lateral malleolus was 96.9%, and the length of vascular pedicle was (3.44±0.65) cm. The flap removal and transposition in 31 patients were successfully completed. The average operation time was 45 minutes (range, 30-65 minutes). After operation, vein crisis and partial necrosis occurred in 4 cases and 3 cases, respectively, which were survived after symptomatic treatment. All the grafts survived and the incisions healed by first intention. All the patients were followed up 3-18 months, with an average of 12 months. At last follow-up, according to the American Orthopaedic Foot and Ankle Society (AOFAS) score, 17 cases were excellent, 11 cases were good, and 3 cases were fair, and the excellent and good rate was 87.5%. CONCLUSION The digital technique can improve the accuracy of perforator localization and the design of peroneal artery perforator propeller flap, and reduce the difficulty of operation, and the risk caused by the variation of vascular anatomy.

Abstract
A variety of reconstructive options including skin grafts, loco-regional flaps, and free flaps exist for the coverage of facial defects. Each technique has advantages and disadvantages. In this study, we present our experience with relaxed skin tension line (RSTL)-oriented, keystone-designed perforator island flap (KDPIF) reconstructions, in consideration of the facial aesthetic unit concept for coverage of small to moderate facial defects.Between May 2016 and February 2018, 17 patients (11 men and 6 women), with an average age of 63.53 years (range: 37-83 years) underwent KDPIF reconstructions to cover facial defects. We performed the KDPIF reconstructions in consideration of the RSTLs and facial aesthetic unit concept. We retrospectively reviewed the defect causes, locations, and sizes, and flap sizes, types, and survivals, as well as the complications. Cosmetic outcomes were evaluated using the Harris 4-stage scale from 3 independent plastic surgeons' point of view, and postoperative satisfactory surveys from all patients.All defects were successfully covered with KDPIF. The defect sizes varied from 1.5 × 1.5 cm to 3 × 3.5 cm. The flap sizes varied from 1.5 × 3 cm to 3 × 5.5 cm. All flaps fully survived and there were no postoperative complications. The average subjective patient satisfaction score was 8.29 (range: 7-10) and the objective cosmetic outcomes were favorable (fair, good, or excellent).Considering its simplicity and safety, the KDPIF is a good reconstruction option with few complications and high reproducibility. The RSTL-oriented KDPIF reconstruction is a good reconstructive option for covering small to moderate facial defects with superior aesthetic outcomes.

Abstract
INTRODUCTION The objectives of this study are: (1) comparison of long-term outcomes after correction of severe gynecomastia using different techniques; (2) apply the Italian version of the BODY-Q; (3) present the role of intercostal perforator flap (ICAP) after massive weight loss for correction of severe gynecomastia. MATERIALS AND METHODS Between January 2008 and March 2016, we performed surgical correction of bilateral severe gynecomastia in 80 men (160 breasts) following massive weight loss. Patients answered the Italian version of BODY-Q postoperative module. All patients had experienced substantial weight loss (> 30 kg), presented with bilateral severe tissue ptosis of the breast, follow-up of almost 2 years and had a good understanding of the Italian language, and signed consents were included in the study. The sample was studied about age, BMI, comorbidity, bariatric surgical procedure, follow-up, type of post-bariatric surgical procedure, complications and secondary procedures. RESULTS We performed 487 severe gynecomastia corrections from 2008 to 2016; 80 patients adhered to the inclusion criteria and formed our study group. This cross-sectional study compared three cohorts: 52 access using a circumareolar scar, 18 with an inframammary fold scar, 10 with an inframammary fold scar using intercostal perforator flaps. There were 16 secondary procedures in group one, 2 in group two and 1 in group three. We compared the secondary procedures of group 1 with the other groups, and we obtained a significant difference with a P = 0.04. The mean patient age was 36.5 years, and the average body mass index was 27.5 kg/m2 at the time of surgical correction of gynecomastia. From the BODY-Q analysis, the group of patients undergoing adenomammectomy with inframammary fold scar using intercostal perforator flaps has achieved significantly better results regarding the satisfaction with chest, psychosocial function, satisfaction with outcome and better body image. CONCLUSIONS This is the first study that used the BODY-Q to analyze the correction of severe gynecomastia following massive weight loss with long-term results. The use of this patient-reported outcome measure underlined that the intercostal artery perforator flap, used in the correction of severe gynecomastia following massive weight loss, is a safe and effective technique with good outcomes and high patient satisfaction.

Abstract
INTRODUCTION The trapezius muscle is a good option for soft tissue defects in the cervical and thoracic regions. However, pedicled flaps raised from perforators in the trapezius are rare. Through a series of cadaver dissections, the authors aim to map the perforating arteries in the trapezius muscle. MATERIALS AND METHODS Dissection of 58 anatomical regions in 32 cadavers was carried out. The perforating arteries of the trapezius were inventoried based on their location, dimensions and frequency using the scapular spine and spinous process line as landmarks. RESULTS In 78% of cases, the main perforators of the trapezius were located along two vertical lines parallel to the spinous process line, 5-6 cm on either side of it, between the scapular spine laterally, the tip of the scapula caudally and the superior margin of the trapezius cranially. On each side of the spinous process line, we found an average of 16 perforators (range 5-27) with an average diameter of 0.6 mm (range 0.1-2.6 mm). CONCLUSION Our study shows that surgeons can use fixed landmarks when developing trapezius perforator flaps.

Abstract
A 37-year-old man complained of a refractory posterior malleolar ulceration on his left ankle. He was diagnosed with Werner syndrome according to the progeroid clinical features and genetic testing. To approach the ulceration, a free flow-through right anterolateral thigh perforator flap with anterolateral thigh cutaneous nerve was harvested. One year later, he was readmitted due to a new ulceration on his right ankle. We harvested the left anterolateral thigh perforator flap with anterolateral thigh cutaneous nerve to reconstruct the defect. After one more year of follow-up, there was no recurrence of ulcers, and the sensation of the flap recovered partially after 6 months. We conclude that free flow-through anterolateral thigh perforator flap is a feasible choice for the repair of foot ulcers in Werner syndrome.

Abstract
UNLABELLED Management of hand and foot defects with exposed tendons is a big challenge for plastic surgeons. Thin vascularized tissue offers an ideal surface for tendon excursion. OBJECTIVE This study examines the reconstructive benefits of a laparoscopy-assisted chimeric peritoneal-deep inferior epigastric artery perforator (DIEP) flap in the treatment of hand and foot injury defects. MATERIALS AND METHODS A retrospective review was performed on 8 patients (6 men, 2 women) that received hand or foot reconstruction with laparoscopy-assisted chimeric peritoneal-DIEP flap. Soft tissue defects of the hand or foot ranged from 16 cm x 10 cm to 22 cm x 14 cm. The peritoneum supplied by the peritoneal branches of the deep inferior epigastric artery was retrieved by laparoscopy to cover exposed extensor tendons, while the DIEP flap consisted of the cutaneous component part of this chimeric flap. RESULTS The flaps survived in 7 of 8 patients. Partial necrosis of the chimeric flap was observed in 1 patient due to venous thrombosis. A split-thickness skin graft then was performed to achieve wound closure on that patient. Motor and sensory functions of these 8 patients improved gradually within the first-year follow-up. CONCLUSIONS The laparoscopy-assisted chimeric peritoneal-DIEP flap is useful for reconstructing defects of the hand and foot with exposed tendons.
