The perforator flaps are based on cutaneous vessels which are originated from a main pedicle and penetrate fascia or muscle to reach the skin. The lateral lower leg is one of the most suitable areas for harvesting perforator flaps because a number of perforator vessels exist. The authors applied peroneal perforator flaps in nine patients. Five flaps were reverse island flaps based on peroneal artery and septocutaneous perforator, and four flaps were free flap based on musculocutaneous perforator only. The recipient site was the posterior ankle in three patients, posterior heel in three patients, lateral malleolus, anterolateral ankle, and foot dorsum in one patient each. The flap size ranged from 5 to 12cm long, from 3 to 5cm wide, and the primary closure of the donor site was possible in most cases. All flaps, except for the flap in two patients in the reverse island flap series, survived completely. The peroneal perforator flap is a very thin, pliable flap with minimal donor site morbidity and is suitable for the reconstruction of small and medium sized superficial skin defects. Also, this flap may be considered as an alternative to radial forearm flap or other perforator flaps.
Calcific myonecrosis is a rare condition in which hypoperfusion due to compartment syndrome causes soft tissue and muscle to become calcified. As calcific myonecrosis gradually deteriorates, secretions steadily accumulate inside the affected area, forming a cavity that is vulnerable to infection. Most such cases progress to chronic wounds that are unlikely to heal spontaneously. After removing the calcified tissue, the wound can be treated by primary closure, flap coverage, or a skin graft. In this case, a 72-year-old man had extensive calcific myonecrosis on his left lower leg, and experienced swelling and increasing tenderness. After removing the muscle calcification, we combined two anterolateral thigh free flaps, which were harvested from the patient's right and left thigh, respectively, to reconstruct the wound with a dead-space filler and skin-defect cover at the same time. The patient recovered without revision surgery or major complications.
Purpose: Electrical burn of scalp is uncommon. Much more, chronically exposed dura in unstable burn scar is quite exceptional. Hence, we report a case of chronically exposed dura following electrical burn. Methods: A 63-year-old man presented with an about 40 years history of an ulcerative lesion arising from electrical burn scar with 'squeeze like sensation' around wound. Wound was about $6{\times}8$ cm. Area in the center was $3{\times}3$ cm nonviable dura without sequestrum. Tangential excision with an intraoperative neurosurgical consultation and transposition flap under general anesthesia was done. Intraoperative biopsy was done. The wound was diagnosed as chronic osteomyelitis, not Marjolin ulcer. Flap was taken successfully. But after 5 days, infectious discharge had been appeared during 2 weeks, despite irrigation and drainage. As flap was re-evaluated, we could see remnant necrotic dura. After that, latissimus dorsi muscle free flap with meshed split thickness skin graft was transferred without excision of necrotic dura. Results: Flap was taken successfully. Follow-up at 10 weeks has been uneventful, with good and stable coverage of the wound. Conclusion: It is true that complete excision of devitalized tissue with sagittal sinus obliteration is prerequisite to flap taken. But necrotic dura was tangentially excised instead of total dura excision, because, posterior two-thirds of the sagittal sinus was involved underneath. Muscle is rich in blood vessels and decrease the recipient-site bacterial count effectively. In this case, muscle flap with skin graft without total dura excision is an alternative treatment.
Background Thoracodorsal vessels (TDVs) and internal mammary vessels (IMVs) have both been widely employed as recipient vessels for use in free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps. However, whether TDVs or IMVs are preferable as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap remains controversial. The purpose of this study was to compare the clinical outcomes when TDVs were used as recipient vessels to those obtained when IMVs were used as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap. Methods A retrospective matched-cohort study was performed. We retrospectively reviewed data collected from patients who underwent a free MS-TRAM flap for autologous breast reconstructions after mastectomy between March 2003 and June 2013. After a one-to-one matching using age, 100 autologous breast reconstructions were selected in this study. Of the 100 breast reconstructions, 50 flaps were anastomosed to TDVs and 50 to IMVs. Patient demographics and clinical outcomes including operation time, length of hospital stay, postoperative complications, and aesthetic score were compared between the two groups. Results No statistically significant differences were found between the two groups in patient demographics and clinical outcomes, including the complication rates and aesthetic scores. There were no major complications such as total or partial flap loss in either group. Conclusions The results of our study demonstrate that both TDVs and IMVs were safe and efficient as recipient vessels in terms of the complication rates and aesthetic outcomes.

Background The anterolateral thigh (ALT) perforator flap has become a popular option for treating soft tissue defects of lower extremity reconstruction and can be combined with a segment of the vastus lateralis muscle. We present a comparison of the use of the ALT fasciocutaneous (ALT-FC) and myocutaneous flaps. Methods We retrospectively reviewed patients in whom free-tissue transfer was performed between 2005 and 2011 for the reconstruction of lower extremity soft-tissue defects. Twenty-four patients were divided into two groups: reconstruction using an ALT-FC flap (12 cases) and reconstruction using a vastus lateralis myocutaneous (VL-MC) flap (12 cases). Postoperative complications, functional results, cosmetic results, and donor-site morbidities were studied. Results Complete flap survival was 100% in both groups. A flap complication was noted in one case (marginal dehiscence) of the ALT-FC group, and no complications were noted in the VL-MC group. In both groups, one case of partial skin graft loss occurred at the donor site, and debulking surgeries were needed for two cases. There were no significant differences in the mean scores for either functional or cosmetic outcomes in either group. Conclusions The VL-MC flap is able to fill occasional dead space and has comparable survival rates to ALT-FC with minimal donor-site morbidity. Additionally, the VL-MC flap is easily elevated without myocutaneous perforator injury.

Background The ability to achieve a long-term, stricture-free urethral repair is one of the ongoing challenges of reconstructive urologic surgery. A successful initial repair is critical, as repeat procedures are difficult, owing to distortion, scarring, and short urethral stumps. Methods We describe a technique in which the gracilis muscle flap is laid on or wrapped around the urethral repair site to provide a well-vascularised soft tissue reinforcement for urethral repair. This technique promotes vascular induction, whereby a new blood supply is introduced to the repair site to improve the outcome of urethral repair or anastomotic urethroplasty. The surface contact between the muscle flap and the repair site is enhanced by the use of fibrin glue to improve adherence and promote inosculation and healing. We employed this technique in 4 patients with different urethral defects. Results After a follow-up period of 32 to 108 months, all of the urethral repairs were successful without complications. Conclusions Our results suggest that the use of a gracilis muscle flap to vascularise urethral repairs can improve the outcome of challenging urethral repairs.

Background The aim of lower-extremity reconstruction has focused on wound coverage and functional recovery. However, there are limitations in the use of a local flap in cases of extensive defects of the lower-extremities. Therefore, free flap is a useful option in lower-extremity reconstruction. Methods We performed a retrospective review of 49 patients (52 cases) who underwent lower-extremity reconstruction at our institution during a 10-year period. In these patients, we evaluated causes and sites of defects, types of flaps, recipient vessels, types of anastomosis, survival rate, and complications. Results There were 42 men and 10 women with a mean age of 32.7 years (range, 3-72 years). The sites of defects included the dorsum of the foot (19), pretibial area (17), ankle (7), heel (5) and other sites (4). The types of free flap included latissimus dorsi muscle flap (10), scapular fascial flap (6), anterolateral thigh flap (6), and other flaps (30). There were four cases of vascular complications, out of which two flaps survived after intervention. The overall survival of the flaps was 96.2% (50/52). There were 19 cases of other complications at recipient sites such as partial graft loss (8), partial flap necrosis (6) and infection (5). However, these complications were not notable and were resolved with skin grafts. Conclusions The free flap is an effective method of lower-extremity reconstruction. Good outcomes can be achieved with complete debridement and the selection of appropriate recipient vessels and flaps according to the recipient site.
Purpose: Cancer arising from the external auditory canal is a rare disease. A lesion that seems harmless in someway, can be lethal when inadequately excised, the tumor may infiltrate nerves, the parotid and auditory tissues before re-invading the skin. Wide resection of the lesion surrounding the structure and reconstruction with an adequate plan is crucial for the treatment of this disease. Methods: Two patients with external auditory canal cancer were treated with muscle flaps and skin grafts. Lateral temporal bone resection (LTBR) was performed for complete resection of the cancer. The defect cavity was obliterated with highly vascularized tissue using pedicled sternocleidomastoid muscle, and temporalis muscle individually, combined with full thickness skin graft for covering the skin defect of the ear. Results: Clear resection margin was obtained, and both patients showed disease free survival during the follow up. There was no complications of hematoma, infection, flap loss, or wound problem in both patients. Both patient received radiation therapy, there was no osteoradionecrosis or any other complication related to radiation therapy. Conclusion: Utilizing pedicled muscle flaps for managing defects after wide resection of the external auditory canal cancer is an effective method for managing this difficult disease.

Background Reconstruction of large soft tissue defects of the lower extremity often requires the use of free flaps. The main limiting factor and potential for complications lie in the selection of proper donor and recipient vessels for microvascular anastomosis. While the superficial veins of the lower leg are easier to dissect, they are thought to be more vulnerable to trauma and lead to a higher complication rate when using them instead of the deep accompanying veins as recipient vessels. No clear evidence exists that proves this concept. Methods We retrospectively studied the outcomes of 97 patients who underwent free flap plasty to reconstruct predominantly traumatic defects of the lower extremity at our institute. The most used flap was the gracilis muscle flap. We divided the population into three groups based on the recipient veins that were used for microvascular anastomosis and compared their outcomes. The primary outcome was the major complication rate. Results Overall flap survivability was 93.81%. The complication rates were not higher when using the great saphenous vein as a recipient vessel when comparing to utilizing the deep concomitant veins alone or the great saphenous vein in combination to the concomitant veins. Conclusions In free flap surgery of the lower extremity, the selection of the recipient veins should not be restricted to the deep accompanying veins of the main vessels. The superficial veins, especially the great saphenous vein, offer an underrated option when performing free flap reconstruction.
Introduction : The Functional muscle transfer is used to reconstruct the injuried muscle and paralysis of the shoulder. Especially transfer of the trapezius has been the treatment of choice but it has disadvantages of inadequate function and deformed contour, and instability of humeral head in case of acromion resection. We report an operation for shoulder reconstruction after wide resection of malignant fibrous histiocytoma, using rotational latissimus dorsi flap and review the operation method and clinical outcome. Materials and Methods : A patient, 53 year old, with malignant fibrous histiocytoma in the acromioclavicular joint area had been underwent wide excision, including the deltoid, clavicular head of pectoralis major, part of trapezius, lateral 1/3 of clavicle and acromion including scapular spine. The rotational latissimus dorsi flap with its neurovascular pedicle was dissected and then placed over the resected area and transfer of muscle attached at coracoid process was done to achieve stability of the humeral head. The range of motion of the shoulder and test of muscle power were evaluated for functional outcome. Total follow-up period is 2 years 11 months. Results : At last follow-up, the range of motion of the shoulder is abduction $90^{\circ}$, flexion $90^{\circ}$, internal rotation $40^{\circ}$, external rotation $50^{\circ}$ and the muscle power is 4 grade in all direction and then we obtained good functional results. There are no complications such as instability or subluxation of the humeral head and deformed contour and he is a disease-free survival state. Conclusions : The transfered latissimus dorsi flap provides adequate lever arm and stabilization and covering of the humeral head by sufficient muscle volume and width. This procedure can be useful not only for the paralysed deltoid reconstruction but also for use in reconstructive surgery after wide resection of the shoulder for malignant tumor.
