Purpose: To evaluate the results of anterolateral thigh perforator free flap for reconstruction of foot and ankle in old diabetic patients. Materials and Methods: Fifteen diabetic foot ulcer patients over the age of 55 were operated with anterolateral thigh perforator free flap. Hematological, hemodynamic, diabetic, bacteriologic and radiologic tests were checked with examination of blood vessel state in both the donor site and the recipient site. After surgery, serial check-up was performed at 6 week, 6 month, and 1 year postoperatively on the survival of transplantation tissue, condition of foot, and condition of walking. Results: There are one case of transplantation failure and four cases of partial tissue-necrosis. Delayed wound-healing was observed both recipient and donor tissue sites. At the final follow up, three cases of small ulcer were found at junction of flap and recipient tissue in plantar area. Fourteen out of fifteen patients could walk without any brace or walking aids. Conclusion: Reconstruction of foot and ankle region in old diabetic patients with the anterolateral thigh perforator free flap is a useful method which can prevent the amputation of foot and ankle.

Sole reconstruction should consider both functional and aesthetic aspects; durable weight bearing surface, adequate contour for normal footwear, protective sensation and solid anchoring to deep tissue to resist shearing. The anterolateral thigh perforator free flap has such favorable characteristics as long pedicle, reliable perforators and minimal donor site morbidity. This flap can be safely thinned to 3-4 mm. It can also be elevated with sufficient bulk with muscles like vastus lateralis for complex defect. Between June 2002 and December 2004, 48 cases of sole reconstruction were performed with anterolateral thigh perforator free flaps. Follow up period ranged from 4 to 34 months with a mean of 14.7 months and with exception of one case, all flaps survived. One case of total flap loss was noted due to infection in a patient who was administered lifetime immunosuppressant. Partial necroses developed in three cases but were treated conservatively. Satisfactory aesthetic and functional results were achieved and acceptable gait recovery was noted. Seventy-eight percent of the patients regained protective sensation by 6 months and earlier sensory recovery was noted in sensate flap group. The authors also present a standardized protocol for preoperative patient evaluation and postoperative management and rehabilitation.

The reconstruction of deep soft tissue defects of lower extremities combined with bone exposure has been difficult problems. When it is impossible to raise local skin flap, we have been usually used the gastrocnemius musculocutaneous flap, cross leg flap or free flaps. However, In musculocutaneous flap, aesthetical appearance of the calf is not appropriate because of too bulky flap. Although the success rate of the free flap has improved, still failure of flap occurs in cases of the chronic ischemic state. As the concepts of perforator flap has recently developed and widely used due to its thin flap thickness. Between January 2002 to December 2004, we treated 7 patients with soft tissue defect in leg with chronic ischemic limbs with perforator island flap. Preoperative angiography were done in all case and we used 2 medial sural perforator flaps, 1 anterior tibial artery perforator flap, 1 posterior tibial artery perforator flap, 3 anterolateral thigh perforator flap. Partial necrosis of flap was seen in one patient but no further surgical procedure was required for wound healed spontaneously. Perforator island flaps are thin, reduce donor site morbidity, conceal donor site with primary closure and it is useful for resurfacing soft tissue defect of lower extremities.

Reconstruction of calvarial bone defects from congenital anomaly or from bone loss due to traumatic or neoplastic processes remains a significant problem in craniofacial surgery and neurosurgery. To facilitate bone regeneration, there have been many trials such as autologous bone graft or allograft, and the addition of demineralized bone matrix and matrix-derived growth factor. Guided bone regeneration is one of the methods to accelerate bone healing for calvarial bone defects especially in children. Pericranium is one of the most usable structure in bone regeneration. It protects the dura and sinus, and provides mechanical connection between bone fragments. It supplies blood to bone cortex and osteoprogenitor cells and enhances bone regeneration. For maximal effect of pericranium in bone regeneration, authors used pericranium as a flap for covering calvarial defects in surgeries of 11 craniosynostosis patients and achieved satisfactory results: The bone regeneration of original cranial defect in one year after operation was 74.6%(${\pm}8.5%$). This pericranial flap would be made more effectively by individual dissection after subgaleal dissection rather than subperiosteal dissection. In this article, we reviewed the role of pericranium and reported its usefulness as a flap in surgery of craniosynostosis to maximize bone regeneration.

The reconstruction of major head and neck defects must be an integral part of the overall cancer treatment plan. The priorities of surgical treatment of head and neck tumor are 1) local tumor control, 2) relief of pain, 3) avoidance of difficult dressing, 4) provision of oral continence, and 5) ability to swallow and manage saliva. The recent advances in reconstructive surgery including the development of musculocutaneous flaps and microvascular free tissue transfer have allowed the surgical restoration of head and neck tumor defects that previously were not possible. These techniques have provided the opportunity to undertake larger, more aggressive resection while at the same time permitting functional rehabilitation. The timing of reconstruction demands on the nature of the resection, the ability of the ablative and reconstructive teams to coordinate efforts, the overall health of the patients, the patient's needs and wishes. So, we report to emphasize current methods for restoring major head and neck tumor defects after tumor ablation, reviewing for the reconstructive operations, postoperative complications, and postoperative sequelae etc, of patients from Jan, 1990 to Dec, 1993.

Purpose: Extensive midface defect following total maxillectomy with orbital exenteration and cheek skin resection should be three dimensionally reconstructed with a large flap that have a sufficient volume of tissue and multiple skin islands. We describe our transverse rectus abdominis myocutaneous(TRAM) free flap with three skin islands which was successfully used in this situation. Methods: A 58-year-old man was performed enbloc total maxillectomy including orbital contents and wide cheek skin because of invasive maxillary squamous cell carcinoma. He was immediately reconstructed with TRAM flap that was designed not vertical but transverse fashion for providing sufficient skin area. Also, deepithelialization procedure making for multiple skin islands was done in flap insetting period when appropriate modification according to the intraoperative situation was possible. Dead space was completely obliterated by bulky muscular tissue, and three skin islands were used for lining of lateral nasal wall, palatal surface, and cheek skin restoration. Results: Postoperative course was satisfying. Maintaining of proper ipsilateral nasal airway, loss of rhinolalia and oronasal regurgitation of food particles, and restoration of cheek contour were successfully obtained. Conclusion: We report clinical experience of threedimensional reconstruction using free TRAM flap after total maxillectomy with orbital exenteration.

Purpose: The goals of cranioplasty are to protect the brain from trauma and restore normal cranial contour with as few complication as possible. In patient who suffered from cranial defect, the most satisfactory form of cranioplasty may be archived with autogenous bone grafts. We report on the treatment of large frontal bone defect using pericranial flap and split-rib graft. Methods: A 29-year-old male was referred to our department. He was involved in an automobile accident resulting in large frontal bone and sinus defect and skull basal defect. The reconstruction was undertaken using galeal frontalis myofascial flap and split-rib cranioplasty using bicoronal incision. Results: The postoperative course was successful. For 9 months follow up period, there was no complication about hematoma, infection, CSF leakage and washboard deformity. He was pleased with the results even when absolute symmetry was not achieved. Conclusion: We experienced large frontal bone and sinus defect and skull basal defect patient and successfully treated with split-rib graft and galeal frontalis myofascial flap.

Purpose: The jejunal free flap is the most standard and reliable procedure of reconstruction of the circumferential pharyngoesophageal defect because it provides pliable, elastic, secreting mucosa and posses reliable vascular anatomy. In this report, the authors introduce the modification of jejunal free flap for decreasing the complications in fatty complicated patients. Method: After harvesting the jejunum with mesentery and mesenteric vessels, both ends of jejunum were excised remaining the mesenteric portion. The jejunal portion of this composite flap was placed to reconstruct esophagopharyngeal defect area and the mesenteric portion was used to obliterate the dead space at paratracheal region and to cover the vital structure and the vascular anastomotic region. Result: A 72 year-old man with recurrent hypopharyngeal cancer who had about 15 cm sized circumferential pharyngoesophageal defect after total pharyngectomy was reconstructed with jejunomesenteric composite free flap without any complications. Conclusion: The mesenteric flaps at both side of jejunomesenteric composite free flap provide the advantages that could obliterate dead space, that could provide cover for the vital cervical vascular structure in case of vascularity was compromised due to previous radiation therapy, and that could preserve as much vascularity at both ends of jejunal flap as possible.
