Background This systematic review compared free anterolateral thigh (ALT) flaps versus pedicled distally based sural artery (DBSA) flaps for reconstruction of soft tissue defects of dorsal foot and ankle in children. Methods A systematic literature search was performed to identify cases where an ALT or DBSA was used to reconstruct the dorsal foot in children. A total of 19 articles were included in the systematic review. Results Eighty-three patients underwent an ALT reconstruction and 138 patients underwent a DBSA reconstruction. Patients who had a DBSA were more likely to require grafting of the donor site (P<0.001). The size of ALT flaps was significantly larger than DBSA flaps (P=0.002). Subsequent flap thinning was required in 30% of patients after ALT and 12% of patients after DBSA reconstruction (P<0.001). Complications occurred in 11.6% of DBSA and 8.4% of ALT flaps (8.4%). Conclusions Both flaps are valid options in reconstructing pediatric foot and ankle defects. Each flap has advantages and disadvantages as discussed in this review article. In general for larger defects, an ALT flap was used. Flap choice should be based on the size of the defect.

The incidence of breast cancer, the second most prevalent cancer type in South Korea, has increased by 6.8% annually in the last six years. The higher number of breast cancer patients has led to an increase in the cases of skin-sparing mastectomies, thereby increasing the need for reconstructive procedures. The reconstruction options include alloplastic techniques such as implant or autologous reconstruction with numerous flaps. The abdominal area is the preferred donor site for the harvest of autologous tissue for breast reconstruction. Breast reconstruction using abdonimal tissue is commonly accomplished using the transverse rectus abdominis myocutaneous (TRAM) flap. The establishment of microvascular surgery led to the development of the free TRAM flap because of its increased vascularity and decreased rectus abdominis sacrifice. The muscle-sparing TRAM, DIEP, and SIEA flap techniques were later developed in an effort to decrease the abdominal-donar-site morbidity by decreasing the injury to the rectus abdominis muscle and fascia. This article summarizes the various abdominal flaps for breast reconstruction.

Frequently, a single muscle flap is not enough to cover a large compound defects after extensive trauma or ablation of tumor. For a extensive defects, several kinds of flaps are available for various needs of reconstruction. The combined latissimus dorsi and serratus anterior flaps provide the largest possible soft tissue coverage. Two flaps composed of latissimus dorsi and serratus anterior muscles are consistently nourished through the subscapular-thoracodorsal vessels and their many branches, and thus the two flaps can be isolated with one vascular pedicled free flap. We experienced 4 cases of reconstruction in closure of extensive compound defects using the combined latissimus dorsi and serratus anterior muscles with one vascular pedicled free flap. The advantages of using these flaps are : 1) its versatlity and excellent malleability 2) easy to dissection 3) long-stalked pedicle 4) the use of a vascularized rib 5) negligible motor dysfunction from the muscle removal.

Thoracodorsal artery (TDA) flaps, ranging from the vascular-pedicled thoracodorsal artery perforator (TDAP) flap, the propeller TDAP flap, and the muscle-sparing latissimus dorsi (MSLD) flap to the conventional latissimus dorsi (LD) flap and the extended LD flap, can all be used for breast reconstruction. The aim of this paper and review is to share our experiences and recommendations for procedure selection when applying TDA-based flaps for breast reconstruction. We describe the different surgical techniques and our thoughts and experience regarding indications and selection between these procedures for individual patients who opt for breast reconstruction. We have performed 574 TDA flaps in 491 patients: 60 extended LD flaps, 122 conventional LD flaps, two MSLD flaps, 233 propeller TDAP flaps, 122 TDAP flaps, and 35 free contralateral TDAP flaps for stacked TDAP breast reconstruction. All the TDA flaps are important flaps for reconstruction of the breast. The LD flap is still an option, although we prefer flaps without muscle when possible. The vascular-pedicled TDAP flap is an option for experienced surgeons, and the propeller TDAP flap can be used in most reconstructive cases of the breast, although a secondary procedure is often necessary for correction of the pedicle bulk. The extended LD flap is an option for women with a substantial body mass index, although it is associated with the highest morbidity of all the TDA flaps. The MSLD flap can be used if the perforators are small or if dissection of the perforators is assessed to be hazardous.

Various local flaps and distant flaps including tongue flap, palatal island flap, and buccal flap as well as skin grafts have been used for the reconstruction of oral mucosal defect. In the posterior region of oral cavity and the buccal cheek area, buccal fat pad can be used as a pedicled graft. The buccal fat pad is different from other subcutaneous fat tissue and it is easily accessible. There are many advantages in pedicled buccal fat pad graft for the closure of oral mucosal defect. The procedure is easy, there is no visible scar in the donor site, it is capable of reconstruction of various contour, and it has good viability. We had used buccal fat pad as a pedicled graft for the closure of oral mucosal defect after the excision of tumor and the oroantral fistula. From the results of these cases, we concluded that the use of the buccal fat pad flaps was worth of the consideration for the reconstruction of oral mucosal defect in the regions of the buccal cheek, and posterior oral cavity.

Introduction : The goal in the management of soft tissue injuries of the lower extremity is to obtain a closed stable wound as soon as possible. Recently, An anatomic study that has shown the role of the vascular axis that follows the superficial sensory nerves in supplying the skin developed the concept of a neuroskin island flap. It has been suggested that skin island flaps supplied by the vascular network of the saphenous nerve is one of the most reliable treatment to skin defect below the knee joint. Purpose : The aim of this article is to present a clinical experience of neuroskin island flaps based on the saphenous nerve and to estimate the clinical utilities of distally based saphenous neuroskin flap. Materials and Methods : From September 1995 to May 2000, a total 12 distally based neuroskin island flaps supplied by the vascular axis of the saphenous nerve were performed to cover defects in pretibial area below the knee. Result : flap necrosis due to reactivation of existing infection developed in a case that skin defect had been on infected nonunion site of tibia. But other 11 cases survived completely without any specific complications. Conclusion : The distally based neuroskin pedicled island flap using the vascular network of the saphenous nerve are versatile and reliable and especially indicated for limited defects in pretibial area below the knee joint which are not good indications for other better-known flaps.

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.

Purpose : Various free flaps and pedicled island flaps are effective for reconstruction of soft tissue defect developed after tumor excision. We want to know the advantage of dorsalis pedis island flap for reconstruction of soft tissue defect caused by soft tissue tumor excision. Materials and Methods : Between 1992 and 2002, we performed 4 dorsalis pedis island flap procedure for reconstruction of soft tissue defect of lower limb developed after soft tissue tumor excision. Average age was 54.7 years old $(40{\sim}68)$, and male 2 cases, female 2 cases. The kinds and number of soft tissue tumors were 2 squamous cell carcinoma and 2 malignant melanoma. The procedures that we performed were all dorsalis pedis island flap. The analysis for the result of treatment was retrospectively accessed by physical examination and questionnaire for whether the change of symptom after operation, range of adjacent joint motion. Also we reviewed associated complication after operative treatment. Results : All dorsalis pedis island flaps were alive. There is no problem for activity of daily living, no skin necrosis and no limitation of motion of adjacent joint. In 1 case of them, the patients died of distant metastasis. Conclusion: Dorsalis pedis island flap procedure as a pedicled island flap procedure is very effective and easy operative procedure for reconstruction of soft tissue defect of lower limb developed after tumor excision compared to free flap procedure because there is no need for microvascular surgery, we can obtain relatively large flap and the lesion and flap donor site locate in the same limb.

Background Pedicled perforator flaps can present postoperative complications similar to those encountered in free flap surgery. Beyond a clinical evaluation, there is still no reliable technical aid for the early prediction of vascular issues. The aim of this study was to assess the support of near-infrared spectroscopy technology as an intraoperative tool to anticipate postsurgical flap ischemia. Methods We prospectively enrolled 13 consecutive patients who were referred to our hospital from March 2017 to July 2018 and required a reconstructive procedure with a pedicled fasciocutaneous perforator flap. We measured flap peripheral capillary oxygen saturation (SpO₂) in each patient with a Somanetics INVOS 5100C Cerebral/Somatic Oximeter (Medtronic), both before and after transposition. Patient demographics, operative data, and complications were then recorded during the following 6 months. We analyzed the data using the Wilcoxon signed-rank test and linear regression. Results The mean flap SpO₂ before and after transposition was 92%±3% and 78%±19%, respectively. The mean change in SpO₂ was 14%±17%, with a range of 0% to 55%. The change in saturation and mean saturation ratio were significantly different between patients with and without postoperative flap necrosis. Conclusions An immediate quantitative analysis of flap peripheral capillary SpO₂ after transposition has never before been described. In our experience, an intraoperative drop in SpO₂ equal to or greater than 15%-20% predicted vascular complications in pedicled perforator flaps. Conversely, flap size and rotation angle were not correlated with the risk of flap necrosis.
