Effects of repair for defect after xanthelasma removal with a orbicularis oculi myocutaneous flap by converse shift grafting / 中华医学美学美容杂志

Objective:To explore the method and effect of blepharoplasty of upper eyelid combined with orbicularis oculi myocutaneous flap in repair of the canthus defect after excision of xanthelasma.Methods:According to the relaxation of the upper eyelid skin and the width of the xanthoma to be removed, the double eyelid line and the peeling line were designed individually, and the myocutaneous flap was removed to repair the inner canthus defect. After resection of the xanthelasma, the orbicularis oculi myocutaneous flap was transferred retrogradely to repair the defect, and then the upper eyelid plasty was performed.Results:During the follow-up of 3-12 months after operation, 13 cases (24 eyes) of the transferred flaps in the inner canthus survived well, the incision scars were hidden, and the double eyelids on both sides were naturally symmetrical.Conclusions:The method of upper eyelid plasty combined with the reverse transfer of orbicularis oculi myocutaneous flap provides more options for the treatment of defects after resection of xanthoma of the inner canthus. The flap survives well, improves the shape of the upper eyelid while completely removing the focus, and avoids complications such as postoperative deformation and obvious scars.

Choices for treatment of pressure sores in different parts of buttocks / 中华显微外科杂志

Objective:To explore the treatment of pressure sores in different parts of the buttocks.Methods:From May, 2005 to March, 2020, 170 (157 patients) pressure sores in different parts of buttocks were treated. Eighty-two pressure sores located at sacrococcyx, 52 at ischial tuberosity, 24 at greater trochanter (without hip joint exposure) and 12 at femoral greater trochanter with exposure of the hip joint. Flaps were used to repair the pressure sores. ①Seventy-one sacrococcygeal pressure sores were repaired by the gluteal epithelial neurovascular flap; ②10 (10 patients) sacrococcygeal and 42 (36 patients) sciatic tubercle pressure sores were repaired by the posterior femoral neurovascular flap; ③24(24 patients) femoral trochanter pressure sores and 1(1 patient) sacrococcygeal pressure sore were repaired by the tensor fascia lata myocutaneous flap; ④2 (2 patients) sciatic tubercle pressure sores were repaired by the gracilis myocutaneous flap; ⑤12 (10 patients) femoral trochanter pressure sores were with hip joint exposure treated with hip joint amputation; ⑥8 (8 patients) pressure sores at ischial tuberosity were treated with VSD. The pressure sores were measured at 5.0 cm×8.0 cm-15.0 cm×30.0 cm, and the flaps were sized 10.0 cm×12.0 cm-17.0 cm×32.0 cm. The follow-up was conducted in 2 methods: visit of outpatient clinic by patients and WeChat distanced interview by medical staff.Results:The gluteal epithelial neurovascular flaps, tensor fasciae lata flaps, gracilis myocutaneous flaps and posterior femoral neurovascular flaps all survived; 4 of 10 posterior femoral neurovascular flaps had partial necrosis and healed after dressing change. A total of 139 patients were treated by flap repair, of which 136 pressure sores healed, except 1 sacrococcygeal pressure sore and 1 femoral greater trochanter pressure sore did not heal because the patient was in old age, long-term hypoproteinaemia and anaemia, and 1 ischial tubercle pressure sore failed to heal due to osteomyelitis osteomyelitis. Ten pressure sores at femoral greater trochanter decubitus with hip joint exposure treated by hip joint amputation and 8 pressure sores at ischial tubercle decubitus treated by simple insertion of VSD were all healed. The follow-up period was 0.5-15.0 years, 7.5 years in average. The results of follow-up showed that pressure sores healed without recurrence in 154 patients, but failed to heal in 3 patients.Conclusion:The gluteal epithelial neurotrophic vascular flap has reliable blood supply and is simple to harvest, and it is a good flap to repair sacrococcygeal pressure sores. The tensor fascia lata myocutaneous flap has reliable blood supply and is simple to harvest, hence it is a good flap to repair greater trochanteric pressure sores. Transposition of the posterior femoral cutaneous nerve nutrient vessel flap or the V-Y advancement flap is simple and effective in repair of the sciatic tuberosity pressure sores. However, it is not recommended to apply the transposition of posterior femoral cutaneous nerve nutrient vessel flap in repair of the sacrococcygobtaineal pressure sore, because it would cause a necrosis at the distal part of the flap. When a greater trochanteric pressure sore coexists with an expose of hip joint, the hip joint can be dissected. For the pressure sore at ischial tuberosity, and if there is a small wound with a large internal cavity, it can be treated with simple insertion of VSD.

Use of Abnobaviscum to treat refractory seroma after breast reconstruction with a latissimus dorsi flap: A case report

In recent years, there has been a notable increase in the rate of refractory donor site seroma, defined as seroma that persists for at least 3 months postoperatively, as the number of breast reconstructions using a latissimus dorsi (LD) musculocutaneous flap has increased. Various factors have been proposed to be related, including smoking, obesity, flap mass, and body weight, and several studies have been conducted to explore treatment methods. Typically, surgical treatment, such as capsulectomy, has been considered for refractory seroma, but in this case report, we describe positive outcomes achieved by using Abnobaviscum to treat three female patients who developed a donor site seroma at least 3 months after breast reconstruction using an LD flap.

Optimized reconstruction of oral and maxillofacial defects with common soft-tissue free flaps / 口腔疾病防治

@#Severe tissue defects in the oral and maxillofacial region are commonly caused by tumor resection and trauma and can impair physiological function and aesthetics in patients. Applying a soft-tissue free flap transfer may avoid exposing important blood vessels and nerves and restore basic anatomical structures and facial features. However, the outcomes of soft-tissue free flap transfer have tended to be unsatisfactory because of the exquisite anatomical structure and complicated functions of the oral and maxillofacial region. Therefore, it is clinically important to choose a proper reconstructive method based on specific tissue defects and to optimize the processes involved in the designing and harvesting of soft-tissue free flaps. In this review, we summarize the application of soft-tissue free flaps in oral and maxillofacial defects and strategies for optimizing the quality of tissue reconstruction.

Comparison of the therapeutic effect between immediate breast re-construction with latissimus dorsi musculocutaneous flap after modified radical mastectomy and conventional modified radical operation on breast cancer / 中国肿瘤临床

Objective:To compare the therapeutic effect of immediate breast reconstruction using latissimus dorsi musculocutane-ous flap after modified radical mastectomy with the conventional modified radical surgery of breast cancer. Methods:A retrospec-tive analysis of 224 female patients with Stage 0 to IIIA breast cancer was conducted. The patients were admitted to the Department of Breast Surgery of Liuzhou People's Hospital between November 2009 and July 2012. The cases were divided into two groups accord-ing to different surgical options:immediate breast reconstruction (IBR) and modified radical surgery of the breast (MRSB). After con-trastive analyses of the postoperative complications, cosmetic results, quality of life, local failure rate, distant metastases and mortality rates between the two groups, the therapeutic efficiency of the two surgeries was evaluated. Results:No statistical differences were ob-served in the postoperative complications between the two groups, such as hydrops, skin flap necrosis, limb exercise and shoulder joint motion, drainage time, and starting time of adjuvant therapy (P>0.05). The patients in the IBR group had a better quality of life than those in the MRSB group (P0.05). Conclusion:Compared with the tradi-tional MRSB group, the option of IBR after modified radical mastectomy not only achieves similar therapeutic outcomes but also pres-ents advantages such as better aesthetic effect of the reconstructed breast, easy surgical procedures, high safety, improvement of the breast contour outline, and improved quality of life after operation. Therefore, IBR is a safe and available therapeutic method for pa-tients with early breast cancer.

Comparison of the Complications in Vertical Rectus Abdominis Musculocutaneous Flap with Non-Reconstructed Cases after Pelvic Exenteration

BACKGROUND: Perineal reconstruction following pelvic exenteration is a challenging area in plastic surgery. Its advantages include preventing complications by obliterating the pelvic dead space and minimizing the scar by using the previous abdominal incision and a vertical rectus abdominis musculocutaneous (VRAM) flap. However, only a few studies have compared the complications and the outcomes following pelvic exenteration between cases with and without a VRAM flap. In this study, we aimed to compare the complications and the outcomes following pelvic exenteration with or without VRAM flap coverage. METHODS: We retrospectively reviewed the cases of nine patients for whom transpelvic VRAM flaps were created following pelvic exenteration due to pelvic malignancy. The complications and outcomes in these patients were compared with those of another nine patients who did not undergo such reconstruction. RESULTS: Flap reconstruction was successful in eight cases, with minor complications such as wound infection and dehiscence. In all cases in the reconstructed group (n=9), structural integrity was maintained and major complications including bowel obstruction and infection were prevented by obliterating the pelvic dead space. In contrast, in the control group (n=9), peritonitis and bowel obstruction occurred in 1 case (11%). CONCLUSIONS: Despite the possibility of flap failure and minor complications, a VRAM flap can result in adequate perineal reconstruction to prevent major complications of pelvic exenteration.

Use of the Anterolateral Thigh and Vertical Rectus Abdominis Musculocutaneous Flaps as Utility Flaps in Reconstructing Large Groin Defects

BACKGROUND: Groin dissections result in large wounds with exposed femoral vessels requiring soft tissue coverage, and the reconstructive options are diverse. In this study we reviewed our experience with the use of the pedicled anterolateral thigh and vertical rectus abdominis musculocutaneous flaps in the reconstruction of large groin wounds. METHODS: Groin reconstructions performed over a period of 10 years were evaluated, with a mean follow up of two years. We included all cases with large or complex (involving perineum) defects, which were reconstructed with the pedicled anterolateral thigh musculocutaneous or the vertical rectus abdominis musculocutaneous (VRAM) flaps. Smaller wounds which were covered with skin grafts, locally based flaps and pedicled muscle flaps were excluded. RESULTS: Twenty-three reconstructions were performed for large or complex groin defects, utilising the anterolateral thigh (n=10) and the vertical rectus abdominis (n=13) pedicled musculocutaneous flaps. Femoral vein reconstruction with a prosthetic graft was required in one patient, and a combination flap (VRAM and gracilis muscle flap) was performed in another. Satisfactory coverage was achieved in all cases without major complications. No free flaps were used in our series. CONCLUSIONS: The anterolateral thigh and vertical rectus abdominis pedicled musculocutaneous flaps yielded consistent results with little morbidity in the reconstruction of large and complex groin defects. A combination of flaps can be used in cases requiring extensive cover.

Chest Wall Reconstruction with a Transverse Rectus Abdominis Musculocutaneous Flap in an Extremely Oversized Heart Transplantation

An 8-year-old girl diagnosed with dilated cardiomyopathy and Russell-Silver syndrome was admitted to our pediatric intensive care unit due to low cardiac output and multiple-organ dysfunction. The patient was placed on the heart transplant waiting list and extracorporeal membrane oxygenation was performed as a bridge to transplantation. After 17 days, heart transplantation was performed. The donor was a 46-year-old female (weight, 50 kg; height, 150 cm). The donor:recipient weight ratio was 3.37:1. Because the dimension and volume of the recipient's thoracic cage were insufficient, the sternum could not be closed. Nine days after transplantation, the patient underwent delayed sternal closure. To obtain adequate space, we left the sternum 4.5 cm apart from each margin using four transverse titanium plates. A transverse rectus abdominis musculocutaneous flap was chosen to cover the wound. Due to the shortage of donors, a size-mismatched pediatric heart transplantation is sometimes unavoidable. Closure of the opened sternum of a transplant recipient can be challenging. Sternal reconstruction after an extremely oversized heart transplantation with transverse titanium plate fixation and a musculocutaneous flap can effectively achieve sternal closure and stability.

Rotational pectoral musculocutaneous flap for the repair of gastric conduit necrosis in cervical esophagogastrostomy / 대한외과학회지

We experienced a case of wide necrosis of the cervical gastric conduit during esophageal cancer surgery. We attempted to repair this defect with various methods including conservative care, stents two times, and sternocleidomastoid muscle flap without successful results. Finally, we were able to reconstruct the gastric conduit defect with rotational pectoralis major musculocutaneous (PMM) flap. PMM flap is thought to be a reconstruction method applicable to the intractable gastric conduit defect.

Using flap or musculocutaneous flap by anatomosis repairs soft tissue defects of serious traumatic shank / 中华显微外科杂志

Objective To summary and discuss the curative effect and experience of repairing serious and complicated soft tissue defects of traumatic shank by flap or musculocutaneous flap by anatomosis.MethodsFrom October 2009 to December 2011, the wounds of 59 patients suffering from serious and complicated soft tissue defects of traumatic shank were covered by VSD after repeated debridement,when the conditions of the whole bodies were stable and the local acute infection was controlled in the main. Fifty-six patients were repaired by a single flap or musculocutaneous flap attributing to the fresh granulation, three patients were repaired by compound tissue flaps because a single flap was insufficient. Five patients who had no available blood vessels at recipient site were repaired by flaps with bridge cross vascular anatomosis. The compound flaps were no more than 2 pieces, the maximum area of flap was 32 cm × 13 cm, the minimum was 15 cm × 8 cm.Results The flaps of all of 59 cases survived, fifty-seven cases were healed in one stage, two in two stage, one case had complication of infection at donate site due to the hematocele, and was cured by debridement and skin graft. Serious and complicated soft tissue defects of shanks were repaired by reconstruction,damaged limbs were salvaged,the functions of the legs were reserved. Conclusion It is the most effective and irreplaceable way that using flaps and musculocutaneous flaps,by anatomosis with the microsurgery technique, repairs the serious and complicated soft tissue defects of shank, which can shorten course and salvage the damaged limbs.

Breast reconstruction using pedicled transverse rectus abdominis musculocutaneous (TRAM) flap

The demand for the breast reconstruction continues to grow following the acute increase in the incidence of breast cancer in Korea. The pedicled transverse rectus abdominis musculocutaneous (TRAM) flap is one of the most commonly used methods among the autologous breast reconstruction options. A pedicled TRAM flap consists of the lower abdominal skin, subcutaneous fat tissue, and one of the rectus abdominis muscles. The blood flow to the flap is supplied through the muscle perforators, which should be strictly selected and preserved. This flap can provide sufficient healthy tissue, which can create the most ideal breast shape. Although the free flap has largely replaced the pedicled TRAM flap, the latter has also evolved with increased understanding of anatomy and physiology. Furthermore, if refined techniques are applied, complications can be minimized and comparable outcomes can be achieved. Besides all the advantages of autologous tissue breast reconstruction, the most distinct feature of the pedicled TRAM flap over the free flap is simplicity of flap elevation and elimination of the microsurgical crisis. The pedicled TRAM flap is still a competitive procedure, yielding consistent results with acceptable complication rates for most patients and should be considered as a primary option for breast reconstruction.

Considerations for Postoperative Results of Pressure Sores around Buttock Region by Musculocutaneous Flaps and Perforator Flaps

PURPOSE: Perforator flaps have been widely used for reconstruction of pressure sores because they have many benefits, especially reducing tension. Otherwise in order to prevent recurrence of a pressure sore, sufficient thickness of a flap is desirable, so a musculocutaneous flap is also useful for reconstruction of a pressure sore. Therefore, the authors considered about the postoperative results of reconstruction of pressure sores between using perforator flaps and musculocutaneous flaps. METHODS: In this study, 33 patients(46 flaps) who underwent reconstructive operation of pressure sores from January 2007 to February 2011 were reviewed. Patients operated by using perforator flaps were 18(18 flaps), and musculocutaneous flaps were 17(28 flaps). We studied postoperative complications and recurrence. RESULTS: We experienced five patients(10 flaps) with complications or recurrences who were operated using musculocutaneous flaps and one patient using a perforator flap. One case using a perforator flap stemmed from dehiscence caused by a urinary fistula occurring in two months after the surgery. Among ten cases using musculocutaneous flaps, one case was caused by total necrosis of flap, five cases by partial necrosis of flap and dehiscence, and four cases by recurrences during follow-up period. CONCLUSION: Even if more cases were required, it can be more considerable to operate using the perforator flap rather than the musculocutaneous flap to reduce the complication or recurrence of pressure sore.

V-Y Latissimus Dorsi Musculocutaneous Flap for Reconstruction of Radiation-induced Skin Injuries on the Back

PURPOSE: Cardiac radiofrequency catheter ablation procedures using fluoroscopy were performed for the treatment of supraventricular and selected ventricular tachyarrhythmia. Fluoroscopy is used to localize the position of the intracardiac catheter. Fluoroscopically- guided procedures often involve high radiation doses to patient's skin, but the incidence of serious radiation injuries in these patients is rare. We reported two cases of severe postradiation skin injury on the back treated with the V-Y latissimus dorsi musculocutaneous flap. METHODS: These two patients underwent radiofrequency catheter ablation under the diagnosis of Woff Parkinson White syndrome(WPW syndrome). They had radiation- induced skin injuries on the subscapular area and these lesions represented chronic ulceration, surrounding induration, hardness, and dyspigmentation. We treated these lesions with complete excision and coverage with V-Y latissimus dorsi musculocutaneous flap. RESULTS: These two patients had no recurrence and no special complications during 20 months and 12 months follow-up periods and were satisfied aesthetically and functionally. CONCLUSION: V-Y latissimus dorsi musculocutaneous flap obtained better results functionally and aesthetically compared with conservative management and skin graft in severe radiation-induced skin injuries after cardiac radiofrequency catheter ablation procedure.

Reason analysis and treatment of post-operative infection of tibial plateau fracture / 中华显微外科杂志

Objective To analyze the reason of post-operative infection of tibial plateau fracture, the therapeutic effect of using pedicle musculocutaneous flaps of proximal leg was researched and summarized. Methods There were 52 patients of tibial plateau fracture after internal fixation complicated by disunion of infected wound and soft tissue defects, traumatic osteomyelitis from January 2005 to May 2009. After pre-operative physical examination, laboratory examination, X-ray, CT scan and bacterial culture of the secretion,the operation, such as debridement, dead bone moving, medullary cavity cleaning, transferring to the external fixation when the internal fixation lost efficacy and bacterial culture of granulation tissue of different levels. The cavity was filled with RBK combined with vancomycin or tobramycin. If the cavity was rather large, autografts from the iliac bone were combined. The tissue defects were covered with pedicle musculocutaneous flaps of proximal leg, and the wound had effective drainage. The antibiotic was used for 3-4 weeks, and the X-rays were given at fixed period until the fracture was cured. Results The soft tissue defects of all 52 patients were repaired well. They were followed from 1 year to 5 years, and the time of bone union ranged from 4 months to 1 year. Two patients of osteomyelitis had a relapse after 3,4 months, then they were cured by the second operation. Three patients had unhealed fracture after 6 months, then they were cured by bone grafting again after 4-6 months. Conclusion Patients of tibial plateau fracture after internal fixation complicated by disunion of infected wound and soft tissue defects, traumatic osteomyelitis should be cured by comprehensive treatments, one of the crucial treatment for success is using pedicle musculocutaneous flaps of proximal leg to fill in lacuna, close wound, improve the local blood supply and promote bone union.

Repair the complex defect of lateral side of ankle with free anterolateral thigh musculocutaneous flap / 中华显微外科杂志

Objective To explore the long-time clinical results and effection of free anterolateral thigh musculocutaneous flap for repairing the complex defects involving lateral or medial malleolar of the ankle and heel,especially for reconstructing stability of the ankle joints. Methods Thirteen patients with complex tissue defects,involving lateral or medial malleolar of the ankle and heel,were treated by free anterolateral thigh fasciomusculocutaneous flap.The fascia lata which was involved in the flap was fixed with the adjacent tissue of the recipient area.The descending branches of the lateral circumflex femoral vessels were anastomosed with the vessels in the recipient area.The largest area of the flap was 20 cm × 12 cm.The ankle joint was fixed in functional position with plaster in the early 3 months post-operatively.The following time ranged from 1.5 years to 20 years.The stability of the ankle joint were evatuated with the patients' objective feeling and clinical symptoms and imaging study.Results The stability of the ankle should be protected by external fixation in the early 3 months postoperatively,and was restored at 6 months usually.In all cases,ten cases were followed over 10 years,six cases were followed over 6 years,three cases were followed over 15 years.Though radiological discovering suggesting traumatic esteoarthritis exited in 3 cases with a follow-up more than 5 years,the clinical manifestations were fair and no one need undergo arthredesis. Conclusion Using ant erolateral thigh musculocutaneous flap for reconstructing the complex defects involving lateral or medial malleolar of the ankle and heel repairing stability of the joint and ovoiding off early arthrodosis of the joint is one of the favorable choice,especially for the teen-agers.
