  • Prior to the advent of microvascular surgery, conventional prosthetic rehabilitation offered limited success to re-establish the physiological function in oromaxillofacial reconstruction. Microvascular surgery provided a new frontier and there are multitude of flaps. Each flap has the benefits and limitation for the application to various defects. Advantage of the scapular flaps over other reconstructive methods include the ability to design multiple cutaneous panels on a separate vascular pedicle allowing improvement in three-dimensional relationship and osseointegrated implants can be palced to restore occlusal and masticatory function. Here I present the detailed description of the important surgical anatomy as well as graft dissection and clinical application of free vascularized scapular flap.

  • Reconstruction following a resection of malignant oral cavity tumors is one of the most difficult problems in recent oral oncology. The radial forearm free flap (RFFF) is a thin, pliable soft tissue flap with large-caliber vessels for microvascular anastomosis. Its additional advantages include consistent flap vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with a tumor resection. For a better understanding of RFFF as a routine reconstructive procedure in oral and maxillofacial surgery, the constant anatomical findings must be learned and memorized by young doctors during the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article discusses the anatomical basis of RFFF in the Korean language.

  • Vascularized tissue coverage is necessary for treatment of soft tissue defect with bone and tendon exposure on hand and foot dorsum, which cannot be successfully covered with simple skin graft or local flap. The temporal fascia is one of the most ideal donor for coverage of soft tissue defect of dorsum of hand or foot in term of ultra-thin, pliable and highly vascular tissue. Also, this flap offers the advantage of a well-concealed donor site in the hair-bearing scalp and smooth tendon gliding. We have experienced 11 cases of reconstruction for soft tissue defect in the hand or foot using temporal fascial flap with skin graft. All cases survived completely and we could gain satisfactory functional results. There were no specific complications except one donor site alopecia We think that the free temporal fascial flap coverage is a highly reliable method for soft tissue defect in hand and foot dorsum. However, the potential pitfalls is secondary alopecia and requirement of skin graft after its transfer.

  • Despite the extensive use of lithotomy position in several plastic surgery procedures, most reports regarding the related incidence of complications are presented in the urologic, gynecologic, and anesthesiologic fields. We present the case of a 54-year-old male patient. polytrauma patient who underwent internal iliac artery embolization leading to extensive gluteal necrosis requiring: debridement, abdominoperineal resection and composite anterolateral thigh flap reconstruction with prolonged lithotomy position. The patient presented lower limb ischemia briefly after surgical theater. A computed tomography scan revealed the obstruction of the left superficial femoral artery requiring emergency revascularization. Arterial thrombosis is a potentially devastating complication and plastic surgeons should be aware of the possible dangers when performing surgeries in prolonged lithotomy position. Preoperative detection of patients at high risks for developing complications should be performed in order to implement preventive measures and avoid potentially life-threatening sequelae.

  • Background Myelomeningocele is a frequently seen condition at tertiary care hospitals. Its treatment involves a variety of plastic reconstructive techniques. Herein, we present a series of myelomeningocele patients treated using keystone flaps. Methods We gathered information regarding soft tissue reconstruction and the use of bilateral keystone flaps to treat myelomeningocele patients. We obtained data from clinical records and recorded the demographic characteristics of mothers and children with the condition. The size, level of defect, and complications detected during the follow-up were analyzed. Results A series of seven patients who underwent bilateral keystone flaps for myelomeningocele closure was analyzed. There were no cases of midline or major dehiscence, flap loss, necrosis, surgical site infections, or cerebrospinal fluid leakage. No revision procedures were performed. Minor complications included one case with minimal seroma and three cases with areas of peripheral dehiscence that healed easily using conventional measures. Conclusions The use of keystone flaps is an adequate option for closure of dorsal midline soft tissue defects related to myelomeningocele. This technique offers predictable results with an acceptable spectrum of complications. Robust blood flow can be predicted based upon anatomical knowledge.

  • Axillary defects need pliable, vascular tissue to cover the critical structures traversing the axilla and to allow near-normal range of motion in the shoulder. Although local flaps are the first choice, free tissue transfer is a good option when local tissues are injured or scarred. Herein, we report two cases of axillary defects that were reconstructed using anterolateral thigh free flaps. One was a post-electric burn axillary defect for which a thoracoacromial pedicle was used as the recipient, and the other was a posttraumatic axillary defect with the transverse cervical vessels as the recipient. In both patients, the flap survived well with no complications and resulted in adequate functional recovery. In large defects of the axilla with a scarcity of local tissues, free flaps can yield optimal results. The proper selection of recipient vessels and a donor flap with adequate pedicle length impact the outcomes of such reconstruction.

  • Free vascularized fibular is the most usuful bony donor of the long bone reconstruction in reconstructive microsurgical field. It has many benifits such as very strong strut tubular bone, very reliable vascular anatomy with large vascular diameter with long pedicle, minimal donor site morbity too. In that situations of the huge long bone defects in distal femur or proximal tibia, the defective bony shape and strength of the transplanted fibular bone is not enough if only one strut of the fibula is transfered. The bony circulation of the fibula has two ways, one from nutrient artery via peroneal artery through nutrient foramen which makes endosteal arterial network inside of the fibula, another way is periosteal network through outside encircling vascular network of the bone which distributed in muscle sleeves of the fibular diaphysis. Authors modified free vascularized fibular bone graft with transverse osteotomy is made from the anterolateral aspect of the fibular shaft just distal to entry of the nutrient artery. This produces two vascularized bone struts that may be folded pararell to each other but that remain connected by the periosteum and muscle cuff surrounding the peroneal artery and veins. The proximal strut is vascularized by both a periosteal and endosteal blood supply, whereas the distal strut is vascularized by a periosteal blood supply alone. This procedure can call "doule barrel" free vascularized fibular graft. We performed 7 cases of doule barrel fashined fibular transplantation on distal femur and proximal tibial large defects. Average bone union time takes 7 months from that procedure. There were no significant bone union time differences between both proximal and distal struts. After solid union of the transfered double barrel fibular graft, there were no stress fracture in our series. We can propose double barrel free vascualized fibular graft is usuful method in that cases with very large bone defect on large long bones especially metaphyseal defects.

  • One of the major advantages of microsurgical reconstruction for defects of the hand is that these techniques allow for selection of the most ideal tissue to reconstruct a particular defect, thus optimizing the functional and aesthetic outcome. The dorsalis pedis free flap is an excellent reconstructive tool for various hand reconstructions. It has a reliable vasculature with vessels that are relative large on a long pedicle. It provides thin pliable tissue and be innervated by deep peroneal nerve. Coupled with its thinness and pliability, it is ideal for innervated cover of critically sensitive area, especially such as the hand. Thus it can be used as a cutaneotendinous flap, or an osteocutaneous flap. Otherwise, the major criticism with this flap is related to its uncertain vascularity and the donor defect. It is the purpose of this paper to outline our technique of flap elevation and donor site closure and to indicate our current use of this flap in hand reconstruction. We have treated 10 cases (6 burn scar contracture cases, 4 acute hand trauma cases) of hand reconstruction from Dec. 3, 1997 to Mar. 4, 2004 using dorsalis pedis free flap. The key points for sucess in terms of a viable flap and acceptable donor site are the preservation of the critical dorsalis pedis-first dorsal metatarsal vascular axis and the creation of a viable bed for grafting. In addition, we substituted preserved superficial fat skin graft for split thickness skin graft and wet environment was offered for good graft take. Preserved superficial fat skin is defined as composite graft containing epidermis, dermis and superficial fat layer. With sufficient care in flap elevation and donor site closure, a good graft take of preserved superficial fat skin under wet environment can be achieved with no functional disability and minimal cosmetic deformity in donor site. This flap has proved itself to be a best choice for hand reconstruction.

  • With the recent progress of microsurgical techniques, radial forearm free flap has an established place in oral reconstruction. Providing thin, soft and pliable skin with a large and constant vascular pedicle, this flap is optimal for intraoral reconstruction. One of the disadvantages of the flap is donor site morbidity, therefore various methods can be used to reduce it. A male complained of palatal and retromolar area mass with ulceration, which was diagnosed as squamous cell carcinoma. He also complained of discomfort and mouth opening limitation, attributed to the location and characteristics of the mass. Because of mouth opening limitation, mandibular swing approach was performed to allow for the surgical approach to the mass. After the surgical excison of the lesion, the intraoral defect was successfully reconstructed with radial forearm free flap.

  • Background : Electrical burns are one of the most devastating types of injuries, and can be characterized by the conduction of electric current through the deeper soft tissue such as vessels, nerves, muscles, and bones. For that reason, the extent of an electric burn is very frequently underestimated on initial impression. Methods : From July 1999 to June 2006, we performed 15 cases of toe tissue transfer for the reconstruction of finger defects caused by electrical burns. We performed preoperative range of motion exercise, early excision, and coverage of the digital defect with toe tissue transfer. Results : We obtained satisfactory results in both functional and aesthetic aspects in all 15 cases without specific complications. Static two-point discrimination results in the transferred toe cases ranged from 8 to 11 mm, with an average of 9.5 mm. The mean range of motion of the transferred toe was $20^{\circ}$ to $36^{\circ}$ in the distal interphalangeal joint, $16^{\circ}$ to $45^{\circ}$ in the proximal interphalangeal joint, and $15^{\circ}$ to $35^{\circ}$ in the metacarpophalangeal joint. All of the patients were relatively satisfied with the function and appearance of their new digits. Conclusions : The strategic management of electrical injury to the hands can be both challenging and complex. Because the optimal surgical method is free tissue transfer, maintenance of vascular integrity among various physiological changes works as a determining factor for the postoperative outcome following the reconstruction.
