  • 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.

  • 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.

  • Purpose: Reconstruction of microtia using costal cartilage graft is commonly used technique nowadays. The chest wall depression at the donor site after the graft, however, has been noticed in many articles. Prevention or correction technique for the depression at the donor site also has been reported and we also have been concerned about the problem. This article is a case report about a new technique preventing chest wall depression after costal cartilage graft. Methods: We selected total 15 microtia patients who visited our clinic, from December 2005 to July 2007. They were 10 male and 5 female patients and the mean age was 11.9 years. The average follow up period was 9.2 months(2 to 15 months). We used 6, 7, and $8^{th}$ costal cartilage for microtia reconstruction. And then we turned over pivot of cartilage resection margin, after bihalving costal cartilage involving about 5-6 cm of $6^{th}$ and $7^{th}$ rib bone. After microtia reconstruction, chest donor sites were evaluated by physical examination and radiography. Results: Postoperative depression at the donor site was much less when the costal cartilage turnover technique was performed. Postoperative physical examination and three dimensional reconstruction CT showed that the rest part of rib bone was turned over and it supported the soft tissue defect during respiration. Conclusion: We expect that the turnover rib bone will not be absorbed after graft, as well as offering mechanical support, compared to the other reports.

  • We experienced satisfactory outcomes by synchronously transplanting an artery and vein using an anterolateral thigh flap pedicle between the vascular pedicle and recipient vessel of a flap for scalp reconstruction. A 45-year-old man developed a subdural hemorrhage due to a fall injury. In this patient, the right temporal cranium was missing and the patient had $4{\times}3cm$ and $6{\times}5cm$ scalp defects. We planned a scalp reconstruction using a latissimus dorsi free flap. Intraoperatively, there was a severe injury to the right superficial temporal vessel because of previous neurosurgical operations. A 15 cm long pedicle defect was needed to reach the recipient facial vessels. For the vascular graft, the descending branch of the lateral circumflex femoral artery and two venae comitantes were harvested. The flap survived well and the skin graft was successful with no notable complications. When an interposition graft is needed in the reconstruction of the head and neck region for which mobility is mandatory to a greater extent, a sufficient length of graft from an anterolateral flap pedicle could easily be harvested. Thus, this could contribute to not only resolving the disadvantages of a venous graft but also to successfully performing a vascular anastomosis.

  • Purpose: Typical cross finger flap is still a good method for reconstruction of fingertip injuries. However, it is necessarily followed by great loss and aesthetically unpreferable result of donor finger. Hereby, we introduce a modification of cross finger flap with reduction pulp plasty and full thickness skin graft, with which we could reduce the defect size of injured fingertip and donor site morbidity at the same time, without any need for harvesting additional skin from other part of hand. Method: This method was performed in the patients with fingertip injuries of complete amputation or in case of loss of fingertip due to necrosis after replantation. Firstly, reduction pulp plasty was performed on the injured finger to reduce the size of defect of fingertip. Additional skin flap was obtained from the pulp plasty. Secondly, cross finger flap was elevated from the adjacent finger to cover the defect on the injured finger. At the same time, defect on the donor finger produced by the flap elevation was covered by full thickness skin graft with the skin obtained from the pulp plasty of injured finger. Results: Flap and graft survived without any necrosis after surgical delay and flap detachment. All of them were healed well and did not present any severe adversary symptoms. Conclusion: Cross finger flap with reduction pulp plasty and full thickness skin graft is an effective method that we can easily apply in reconstruction of fingertip injury. We think that it is more helpful than the usual manner, especially in cases of children with less soft tissue on their fingers for preservation and reduction of the morbidity of donor finger.

  • Purpose: Reconstruction of a full thickness defect of the nose is a difficult task for plastic surgeons because the anatomical characteristic, shape, and function of the nose all need to be taken into consideration. Most often, a local flap or a composite graft is used, but for a large defect, reconstruction using free flaps is the most ideal method. In free flap reconstruction, the chondrocutaneous preauricular area can be a suitable donor site. We performed a chondrocutaneous preauricular free flap with an interpositional vascular graft for reconstruction of a nasal ala. Methods: A 46 year-old male presented to the hospital with a right alar deformity induced by a dog bite. During the surgery, the existing scar tissue was removed and thereby a newly formed full thickness defect was reconstructed using the chondrocutaneous preauricular free flap with an interpositional vascular graft harvested from the descending branch of the lateral femoral circumflex vessel between the facial and superficial temporal vessels of the free flap. Results: The flap survived without flap loss and showed symmetry in its overall shape, contour, texture, and color. The patient was satisfied with the results and the surgery yielded no additional scars at the nasolabial fold area. Conclusion: The chondrocutaneous preauricular free flap is a valuable method in reconstruction of full thickness defects of the nose, and using the descending branch of the lateral femoral circumflex vessel as the interpositional vascular graft at the anastomotic site produces reliable results.

  • Background: The mental V-Y advancement flap method is useful for reconstruction of lower lip defect because of its many advantages. However, it is not easy to select the optimal reconstructive method for the vermilion defect that remains after application of the mental V-Y advancement flap. In choosing the representative surgical method for vermilion mucosal reconstruction including mucosal V-Y advancement flap, buccal mucosal flap, and buccal mucosal graft. We describe an efficient technique to large lower lip defects combining mental V-Y advancement flap and buccal mucosal graft Methods: This study included 16 patients who underwent reconstructive surgery for full-thickness and large defect (> half the entire width) of the lower lip from October 2006 to September 2017. The operation was conducted using mental V-Y advancement flap with various vermilion mucosal reconstruction methods considering the location of the defect and the amount of residual tissue of the lip coloboma after excision. Results: All patients underwent mental V-Y advancement flap. In vermilion mucosal reconstruction, five patients underwent mucosal V-Y advancement flap, three underwent buccal mucosal flap, and eight underwent buccal mucosal graft. There were good aesthetic and functional results in all patients who underwent buccal mucosal graft. However, two patients who underwent mucosal V-Y advancement flap complained of oral incompetence, and all patients who underwent buccal mucosal flap had oral commissure deformity. Conclusion: Buccal mucosal graft combined with mental V-Y advancement flap can produce suitable functional and aesthetic outcomes in near total lower lip reconstruction in patient with large mucosal defect including vermilion portion.

  • Patients with cleft lip and palate require interdisciplinary treatment to achieve successful rehabilitation. However, there are special difficulties in orthodontic treatment of adult cleft lip and palate patients: 1. Lack of Tissue, Bone, and Soft tissue; 2. Heavy Scar Tissue, Vestibule, and Palate; 3. Severe Anteroposterior discrepancy and Impaired Maxilla; 4. Distortion of Alveolar Ridge; 5. Abnormal Eruption Path and Malalignment of Tooth. Solving these problems, orthodontist should have differential diagnosis on extent of cleft site and residual deformities of adult cleft lip and palate patient. The tooth missing area in cleft site was commonly treated with a removable or fixed prosthesis, but this method is not stable to retain maxillary arch shape. To establish the more stable arch shape in cleft lip and palate, endosseous implants in the alveolar clefts with bone graft is helpful for management of adult cleft lip and palate patient.

  • Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome can be treated through numerous surgical and nonsurgical methods. We present a surgical technique in which a neovagina was reconstructed and shaped by a vaginal expander with acellular porcine dermal matrix (XCM Biologic Tissue Matrix) and mucosal interposition using microfragments harvested from the hymen. In our case, we found this procedure to be safe and effective, resulting in satisfactory sexual function and good cosmetic results, without donor site morbidity. To our best knowledge, this tissue-engineered biomaterial has never been used for vaginal reconstruction before.

  • The soft tissue triangle is an easily recognizable subunit of the nose. Therefore, deformities in this region resulting from trauma or complications after cosmetic surgery can have serious cosmetic impacts. Various reconstruction choices exist for deformities such as depression of the soft triangle but choosing the most appropriate treatment in each case remains a challenge. In the case described herein, a patient underwent augmentation rhinoplasty with a silastic implant and experienced implant exposure in the soft triangle area. After implant removal, the patient complained of depression in this area. The authors effectively solved this problem through a de-epithelialized composite tissue graft. In this report, we present this case and review similar cases of reconstruction of the soft triangle.
