BACKGROUND: Malignant chest wall tumors need to be excised with wide resection to ensure tumor free margins, and the reconstruction method should be selected according to the depth and dimensions of the tumor. Vascularized tissue is needed to cover the superficial soft tissue defect or bone tissue defect. This study evaluated differences in complications according to reconstruction strategy.
METHODS: Forty-five patients with 52 operations for resection of malignant tumors in the chest wall were retrospectively reviewed. Patients were categorized as having superficial tumors, comprising Group A with simple closure for small soft tissue defects and Group B with flap coverage for wide soft tissue defects, or deep tumors, comprising Group C with full-thickness resection with or without mesh reconstruction and Group D with full-thickness resection covered by flap with or without polymethyl methacrylate. Complications were evaluated for the 52 operations based on reconstruction strategy then risk factors for surgical and respiratory complications were elucidated.
RESULTS: Total local recurrence-free survival rates in 45 patients who received first operation were 83.9% at 5 years and 70.6% at 10 years. The surgical complication rate was 11.5% (6/52), occurring only in cases with deep tumors, predominantly from Group D. Operations needing chest wall reconstruction (p = 0.0016) and flap transfer (p = 0.0112) were significantly associated with the incidence of complications. Operations involving complications showed significantly larger tumors, wider areas of bony chest wall resection and greater volumes of bleeding (p < 0.005). Flap transfer was the only significant predictor identified from multivariate analysis (OR: 10.8, 95%CI: 1.05-111; p = 0.0456). The respiratory complication rate was 13.5% (7/52), occurring with superficial and deep tumors, particularly Groups B and D. Flap transfer was significantly associated with the incidence of respiratory complications (p < 0.0005). Cases in the group with respiratory complications were older, more frequently had a history of smoking, had lower FEV1.0% and had a wider area of skin resected compared to cases in the group without respiratory complications (p < 0.05). Preoperative FEV1.0% was the only significant predictor identified from multivariate analysis (OR: 0.814, 95%CI: 0.693-0.957; p = 0.0126).
CONCLUSIONS: Surgical complications were more frequent in Group D and after operations involving flap transfer. Severe preoperative FEV1.0% was associated with respiratory complications even in cases of superficial tumors with flap transfer.

Background: Nitroglycerin is suggested to improve flap survival based on promising results; however, there are no data on the effectiveness of treatment initiation time. This study aimed to compare the effect of various nitroglycerin treatment initiation times on partial flap survival. Materials and Methods: The study included 50 Sprague-Dawley rats. Modified McFarlane flaps were elevated on the dorsum of each rat. Group A received placebo treatment. Groups B, C, D, and E received topical nitroglycerin 2% starting 1 day before surgery, on the day of surgery, postoperative d 2, and postoperative d 4, respectively. After 7 days, the flap survival rates were calculated. Afterward, the severity and extent of inflammation and ischemia, and the severity of edema were evaluated histologically. Results: The flap survival rate was highest in group B, followed by groups C, D, E, and A. The difference between groups B and C was not significant, whereas the difference between group B and groups A, D, and E was. In addition, the difference between groups A, D, and E was not significant. Histological analysis showed that inflammation was less severe in groups B and C than in groups A, D, and E. Ischemia was the most severe in groups A and D and was the least severe in group C. Conclusion: Topical nitroglycerin treatment increases flap survival when initiated before or on the day of surgery, but has no benefit when initiated on postsurgery d 2 or 4. Preoperative initiation of nitroglycerin treatment positively affects flap survival.
Contexte: L’utilisation de la nitroglycérine a été proposée pour améliorer la survie d’un lambeau à partir de résultats prometteurs. Il n’y a cependant aucune donnée sur l’efficacité du délai d’instauration du traitement. Cette étude a visé à comparer l’effet de différents moments d’instauration du traitement avec la nitroglycérine sur la survie d’un lambeau partiel. Matériels et méthodes: L’étude a inclus 50 rats Sprague-Dawley. Des lambeaux modifiés de McFarlane ont été surélevés sur le dos de chaque rat. Le groupe A a reçu un placebo, tandis que les groupes B, C, D et E ont reçu de la nitroglycérine topique à 2% en commençant, respectivement, la veille de la chirurgie, le jour de la chirurgie, 2 jours et 4 jours postopératoires. Les taux de survie du volet ont été calculés après 7 jours. Ensuite, la sévérité et l’étendue de l’inflammation et de l’ischémie ainsi que la sévérité de l’œdème ont été évaluées histologiquement. Résultats: Le taux de survie des volets a été le plus élevé dans le groupe B, suivi des groupes C, D, E et A. La différence entre les groupes B et C n’était pas significative, tandis que la différence entre le groupe B et les groupes A, D et E l’était. En outre, la différence entre les groupes A, et E n’était pas significative. L’analyse histologique a montré que l’inflammation était moins sévère dans les groupes B et C que dans les groupes A, D et E. L’ischémie a été la plus importante dans les groupes A et D et la moins importante dans le groupe C. Conclusion: Le traitement topique avec la nitroglycérine augmente la survie d’un lambeau quand il est commencé le jour de la chirurgie ou avant, mais il n’apporte pas d’avantage s’il est instauré au 2e ou au 4e jour postopératoire. L’instauration d’un traitement par la nitroglycérine en préopératoire a un effet positif sur la survie des lambeaux.

Maxillary canines are often impacted, which can result in tooth disorders and adversely affect occlusal and facial development. The case report describes complete bilateral impaction of maxillary canines and significant root resorption of a central incisor. The multidisciplinary approach is the optimal strategy for addressing impacted maxillary canines.

OBJECTIVE: Septal perforations (SPs) present a distinct challenge. There are many described surgical approaches with variable success rates. The goal of this study is to describe a new technique in repairing SP.
METHODS: A case series of eighteen patients with anterior septal perforation who underwent endoscopic repair with the \"tunnel technique\" based on anterior ethmoid artery flap (AEA) were analyzed. Demographic data, etiology, size of perforation, and success rate were collected.
RESULTS: Eighteen cases with male predominance (67%) were enrolled from 2019 to 2022. The average perforation size was 1.5 cm (0.5- 3.6 cm). The success rate of complete SP closure was 94% (n = 17/18) with no complications after surgery. The patients were followed up for 7 ± 5.2 months.
CONCLUSIONS: AEA flap reconstruction with the tunnel technique is associated with favorable outcomes in SP closure. The tunnel technique provides a useful flap bolster and minimizes the use of other supportive measures. This technique offers an addition to other techniques for septal perforation repair.
METHODS: Level 4.

OBJECTIVE: To compare the clinical outcomes of anterolateral femoral interregional flap with turbocharge technique and traditional anterolateral femoral flap in repair of limblarge wound surface.
METHODS: Clinical data of 38 patients withlimb large wound surface (11 cm×39 cm-16 cm× 65 cm) admitted to the Department of Prosthetics and Reconstruction of Sir Run Run Shaw Hospital from May 2018 to May 2022 were retrospectively analyzed. Eighteen patients were treated by anterolateral femoral perforator flap and superficial circumflex iliac artery flap (ALTP-SCIAP) with turbocharge technique (interregional flap group); while 20 patients were treated with unilateral or bilateral anterolateral femoral flaps, combined with skin grafting if necessary (traditional anterolateral femoral flap group). The survival of skin flap, repair of donor area, complications and patient satisfaction were compared between the two groups.
RESULTS: In interregional flap group, 18 flaps were harvested and transplanted, the flap width, length and the viable area were (9.9±2.0) cm, (44.2±3.5) cm and (343.2±79.9) cm2, respectively. In traditional anterolateral femoral flap group and 29 flaps were harvested and transplanted, the flap width, length and the viable area were (11.0-2.8) cm (21.7-3.2) cm and (186.4-49.2) cm2, respectively. There were significant differences in the flap length and survival area between the two groups (t=22.365 and 8.345, P<0.05), but not significant difference in the flap width (t=1.525, P>0.05). In the interregional flap group, the donor site of flap was closed by direct suture in 11 cases, by skin retractor assisted suture in 6 cases, and by skin grafting in 1 case. In traditional anterolateral femoral flap group, the donor site of flap was closed by direct suture in 12 flaps, by skin retractor assisted suture in 11 flaps, and by skin grafting in 6 flaps. No significant difference was found between the two groups (χ2=2.657, P>0.05). The interregional flap group had lower postoperative complications rate (5.6% vs. 35.0%, χ2=4.942, P<0.05) and higher patient satisfaction rate (94.4% vs. 70.0%, χ2=4.448, P<0.05) than traditional anterolateral femoral flap group.
CONCLUSIONS: Compared with the traditional anterolateral thigh flap, the anterolateral femoral interregional flap with turbocharge technique has a larger flap area, less complications, and higher patient satisfaction rate. With sacrificing only one donor area and sharing a set of vascular pedicles, it can repair \"super long\", \"super large\" or irregular limb wound defects maximally. At the same time, most of the donor areas of the flap can be sutured directly without skin grafting.
目的: 对比结合内增压技术的股前外侧跨区皮瓣与传统股前外侧皮瓣在修复肢体较大创面软组织缺损中的临床疗效。方法: 回顾性分析2018年5月—2022年5月浙江大学医学院附属邵逸夫医院收治的肢体较大创面缺损共38例患者（缺损面积达到11 cm×39 cm~16 cm×65 cm），按照修复方式的不同，分为跨区皮瓣修复组（18例）和传统皮瓣修复组（20例）。跨区皮瓣修复组采用结合内增压技术的股前外侧穿支皮瓣联合旋髂浅动脉皮瓣（ALTP-SCIAP）治疗，传统皮瓣修复组采用单侧或双侧股前外侧皮瓣，必要时联合植皮。比较两组术后皮瓣存活情况、供区修复、并发症、患者满意度等。结果: 跨区皮瓣修复组共18例患者，切取移植皮瓣18例次，瓣宽为（9.9±2.0）cm，瓣长为（44.2±3.5）cm，存活面积为（343.2±79.9）cm2。传统皮瓣修复组共20例患者，切取移植皮瓣29例次（11例患者切取单侧股前外侧皮瓣联合刃厚植皮修复，9例患者切取双侧股前外侧皮瓣进行修复），瓣宽为（11.0±2.8）cm，瓣长为（21.7±3.2）cm，存活面积为（186.4±49.2）cm2。两组皮瓣瓣宽差异无统计学意义（t=1.525，P>0.05），瓣长和存活面积跨区皮瓣修复组显著大于传统皮瓣修复组（t=22.365和8.345，均P<0.05）。跨区皮瓣修复组皮瓣供区采用直接缝合11例次，皮肤牵拉器辅助下缝合6例次，部分植皮修复1例次。传统皮瓣修复组皮瓣供区采用直接缝合12例次，皮肤牵拉器辅助下缝合11例次，部分植皮修复6例次。两组差异无统计学意义（χ2=2.657，P>0.05）。跨区皮瓣修复组中出现并发症1例，患者满意度达到94.4%；而传统皮瓣修复组中出现并发症7例，患者满意度为70.0%且明显低于跨区皮瓣修复组（χ2=4.448，P<0.05）。结论: 与传统股前外侧皮瓣相比，结合内增压技术的股前外侧跨区皮瓣切取面积更大，并发症更少，患者满意度更高，只牺牲一个供区，共用一组血管蒂，就可以最大限度的修复“超长”、“超大”或不规则的肢体创面缺损，而皮瓣供区大多可Ⅰ期直接缝合，不需要植皮修复。.

BACKGROUND: Breast reconstruction after cancer surgery through lipomodeling can be performed alone or in combination with a flap. Our objective is to describe the proportion of techniques used on patients who underwent autologous reconstructive surgery after tumorectomy or mastectomy in Franche-Comté.
METHODS: A bicentric retrospective observational study was conducted between October 2017 and December 2021 (NCT06101732), including three groups: those who underwent exclusive lipomodeling reconstruction after mastectomy (1) or in addition to a flap (2), and those who underwent exclusive lipomodeling reconstruction after tumorectomy (3). Socio-demographic, medical, and surgical data were collected and recorded in a specially designed software.
RESULTS: Two hundred and fifty-one lipomodeling procedures were performed on 91 patients. In group 1, the average transferred volume was 1191mL with an average number of sessions of 4.4 spreads over 19.4months. In group 2, the average transferred volume was 676mL with an average operative time of 2.5 spread over 16.1months. In group 3, the average transferred volume was 223mL with an average number of sessions of 1.5 spreads over 6.2months. Regarding postoperative complications, 11% had cysts of fat necrosis, 4.4% had infections, and 2.2% had hematomas.
CONCLUSIONS: Lipomodeling is a technique that has clearly established itself in the field of breast reconstructive surgery. It results in a few complications and improves the final aesthetic outcome whether used exclusively or in addition to a flap.

UNASSIGNED: Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) presents significant challenges, especially in elderly and comorbid patients, often necessitating revision surgeries. We report on a series of patients with confirmed PJI of the knee and concomitant soft-tissue/extensor apparatus defects, treated by using pedicled myocutaneous medial or lateral sural artery perforator (MSAP/LSAP) gastrocnemius flaps.
UNASSIGNED: Our retrospective study at the Center for Musculoskeletal Infections, included patients with knee PJI undergoing pedicled myocutaneous MSAP/LSAP gastrocnemius flap reconstruction for combined soft tissue and extensor apparatus defects. The tendinous back of the gastrocnemius muscle was used and, if required, the Achilles tendon for extensor apparatus reconstruction, with the skin island addressing the cutaneous defect. Perioperative complications and postoperative outcomes after 1 year were evaluated, including functional and clinical assessments with the American Knee Society Score (AKSS).
UNASSIGNED: Eight patients (mean age 73 years; five female) were included, predominantly with Staphylococcus aureus infections. Six patients involved isolated MSAP flaps, two were extended with the Achilles tendon. The median time for wound healing was 9 days. Short-term follow-up showed successful reconstruction in seven patients, with minor wound dehiscence in one patient. One patient required flap revision for a perigenicular haemato-seroma and two patients were diagnosed with new haematogenous PJI infection. Significant improvement in AKSS scores after surgery was observed (functional AKSS: median 33-85; clinical AKSS: median 64-91, p = 0.001).
UNASSIGNED: Pedicled myocutaneous MSAP/LSAP gastrocnemius flaps offer a safe, reliable and versatile option for reconstructing combined soft tissue and extensor apparatus defects in PJI after TKA. This approach yields excellent functional outcomes with minimal peri- and postoperative complications, which is particularly beneficial in elderly and comorbid patients and feasible in settings without microsurgical availability.
UNASSIGNED: Level IV.

OBJECTIVE: The choice of surgical technique for aponeurectomy in Dupuytren\'s disease is controversial due to varying outcomes and complication rates. The Malingue plasty has shown mathematical and mechanical advantages, but long-term efficacy and results compared to other techniques have never been reported. This study aimed to evaluate the long-term functional, esthetic and recurrence outcomes of Malingue plasty in Dupuytren\'s disease.
METHODS: The study included patients who underwent aponeurectomy with Malingue plasty performed by a highly experienced surgeon between January 2014 and December 2016, with a minimum follow-up of 5 years. Preoperative records were analyzed. At follow-up, extension lag was analyzed in each joint (metacarpophalangeal, proximal interphalangeal and distal interphalangeal) in each operated finger, as well as signs of recurrence or extension of the disease. Function and esthetics were assessed using the QuickDASH (Disabilities of the Arm, Shoulder and Hand) questionnaire and the Michigan Hand Outcomes Questionnaire.
RESULTS: Out of 107 eligible patients, 55 were included in the study after exclusions and loss to follow-up. Three patients required revision surgery for recurrence during follow-up. All preoperative deformities of the proximal interphalangeal and metacarpophalangeal joints were corrected postoperatively, and no intraoperative or postoperative complications occurred. Mean extension deficit at follow-up was 18.1 °. Only the little finger showed significant loss of correction (p = 0.02). Mean QuickDASH score was 13.2 and the overall Michigan Hand Outcomes Questionnaire score was 91.8%. Recurrence affected 50% of patients according to the Leclercq criteria and 27.5% according to the Felici criteria.
CONCLUSIONS: Although Malingue plasty did not improve the recurrence rate in Dupuytren\'s disease compared with other techniques, its advantages in terms of functional improvement and complications make it an interesting surgical option.

OBJECTIVE: Genital burns are rare injuries. Reconstruction of penile skin defects should consider cosmetic and functional outcomes. Skin grafts can develop scar contractures and carry hair follicles, causing unwanted results. These downsides remain unsolved issues. This work aimed to describe a new foreskin advancement flap method for completely reconstructing penile shaft skin defects in severely burned patients.
METHODS: From 2021 to 2023, four patients with third-degree burns in the genital area were enrolled in this investigation. We describe a series of cases with deep burns to the penile shaft and surrounding area that needed debridement and reconstruction using a novel technique called \"reverse circumcision,\" which consists of tangential excision of the penis and a foreskin advancement flap without longitudinal cuts with less morbidity, preservation of function, and a better aesthetic appearance. The patients had an average follow-up of nine months.
RESULTS: The reverse circumcision technique was established for patients with severe burns in the genital area. The four patients were satisfied with the postoperative results and the aesthetic results of the procedure without reporting any complications. No scarring or contractures were observed on the glans or penile shaft after surgery.
CONCLUSIONS: Compared with other flap methods, the use of a reverse circumcision foreskin advancement flap was more straightforward, feasible, and effective. In adults, the foreskin tissue completely covers the penile shaft skin defect. It is a viable reconstructive surgical technique that is easily reproducible and has excellent aesthetic and functional results. For this surgical technique, tissue transfers, bulky regional flaps, or skin grafts were not needed.
