Prosthetic reconstruction of musculoskeletal defects about the knee for tumor has many advantages, particularly the maintenance of motion and immediate functional restoration. But, prosthetic reconstruction has inherent limitations in terms of long-term durability. The authors have reported here a patient who had mechanical failure at 61 months later following use of a modular resection system to reconstruct the segmental defect of proximal tibia in osteosarcoma. In this case, another technique of extensor mechanism reconstruction using Achilles tendon allograft was attempted. Because of the concerns involving durability of tumor prosthesis, increased emphasis has to be placed on innovation in prosthetic design.

The microwave tissue coagulation therapy was originally used for hemostasis in the hepatic surgery, which is effectively applied in the endoscopic surgery such as the hemostasis of gastric ulcer or tumor bleeding, stenosis relieving of esophageal or rectal stenosis and tumor reduction in inoperable early cancer cases.We experienced one case of the restenosis after the tracheal reconstruction. The patient, who was 42 year-old male, had severe dyspnea due to the tracheal stenosis for 4 years. The resection of tracheal stenosis and tracheal reconstruction was done. But the restenosis occurred at the tracheal anastomosis site because of the protrusive granulation at one month after operation. The patient was successfully treated by the microwave tissue coagulation therapy.

Recently, computer-assisted surgery is popular for performing well-planned operations. Computer-aided navigation system is helpful in maxillofacial surgery with real time instrument positioning and clear anatomic identification. Generally, segmental mandibulectomy and reconstruction flap surgery have done by extra-oral approach such as, submandibular approach. This case report describes performing intra-oral segmental mandibulectomy and reconstruction with monocortical deep circumflex iliac artery (DCIA) flap and CT guided implant surgery by using computer-aided surgical guide and navigation for managing ameloblastoma in a 31 years old female patient.

The reconstruction of the mandible is a complex procedure because various cosmetic as well as functional challenges must be addressed, including mastication and oral competence. Many surgical techniques have been described to address these challenges, including non-vascularized bone grafts, vascularized bone grafts, and approaches related to tissue engineering. This review summarizes different modifications of the free vascularized fibula graft, which, since its introduction by Hidalgo in 1989, has become the first option for mandibular reconstruction. The fibula free flap can undergo various modifications according to the individual requirements of a particular reconstruction. Osteocutaneous flaps can be harvested for reconstruction of composite defects. 'Double-barreling' of the fibula can, for instance, enable enhanced aesthetic and functional results, as well as immediate one-stage osseointegrated dental implantation. Recently described preoperative virtual surgery planning to facilitate neomandible remodeling could guarantee good results. To conclude, the free fibula bone graft can currently be regarded as the "gold standard" for mandibular reconstruction in case of composite (inside and outside) oral cavity defects as well as a way of enabling the performance of one-stage dental implantation.

Purpose: The anatomical anomaly of the rectus abdominis muscle and it's fascia is very rare. No case of the absence of the linea alba below the umbilicus has yet been reported. During breast reconstruction with pedicled TRAM flap, we experienced one case of absence of linea alba. Methods: The patient was a 38-years old female who underwent immediate breast reconstruction with pedicled TRAM flap after Right modified radical mastectomy in June 2010. While the TRAM flap was being elevated, bilateral twitching of the rectus abdominis muscle occurred when electrocautery was applied, and we found the absence of the linea alba below the umbilicus. Results: When the rectus abdominis muscle was exposed, the linea alba below the umbilicus was not observed, and the bilateral rectus abdominis muscle was indistinguishably fused in a gross observation. In addition, bilateral twitching of rectus abdominis muscle was simultaneously observed as one muscle unit when electrocautery was applied. As with both rectus abdominis muscles was bluntly dissected with scissors, the scanty fatty tissues were observed between the both rectus muscles, and the bilateral rectus abdominis muscle was easily separated. The flap was transposed into the corresponding defect to make breast mound. Midline fascia was fixed to the posterior rectus sheath to reconstruct smilar anatomic linea alba. Abdominal defect was reinforced by suturing between remaining anterior rectus sheath. Conclusion: As the unexpected anatomical anomaly may affect the operation outcome, surgeons should be careful when they unexpectedly encounter the anatomical anomaly during an operation. Here, we report a rare case of absence of the linea alba seen at the time of pedicled TRAM flap elevation for breast reconstruction.

Soft-tissue deficits over the plantar forefoot, plantar heel, Achilles tendon, and distal parts of lower leg are often troublesome to cover with a simple graft or local flap due to limited mobility of surrounding skin and poor circulation in these area. Soft-tissue reconstruction in these regions should provide tissue components similar to the original lost tissue, supply durability and minimal protective pressure sensation and result in a donor site that is well tolerated and treated. We analysed 7 cases that were treated with the Instep flap due to soft-tissue defects over these regions from July of 1990 to July of 1993. All flaps were viable and successful at follow-up. 1. The age ranged from 9 years to 60 years, and 6 cases were male and 1 case female. 2. The sites of soft-tissue loss were the plantar forefoot(1 case), plantar heel(3 cases), Achilles tendon(2 cases), and distal parts of lower leg(1 case). 3. The causes of soft-tissue loss were simple soft-tissue crushing injury(1 case), crushing injury of the 1st toe(1 case) and posttraumatic infection and necrosis(5 cases). 4. The associated injury were open distal tibio-fibula, fracture(2 cases), medial malleolar fracture of the ankle(1 case), Achilles tendon rupture(2 case) and 1st metatarso-phalangeal disarticulation(1 case). 5. The size of flap was from $3{\times}4cm$ to $5{\times}10cm$(average $4{\times}5.6cm)$. 6. In 7 cases, we were not to find post-operative necrosis and infection, non-viability, limitation of ankle joint, and gait disturbance caused by the Instep flap surgery. 7. This study demonstrates that the Instep flap should be considered as another valuable technique in reconstruction of these regions.

We report a case of autologous breast reconstruction in which a thoracodorsal vessel was used as a recipient vessel after a hypoplastic internal mammary vessel was found on preoperative computed tomography (CT) angiography. A 46-year-old woman with no underlying disease was scheduled to undergo skin-sparing mastectomy and breast reconstruction using a deep inferior epigastric artery perforator flap. Preoperative CT angiography showed segmental occlusion of the right subclavian artery with severe atherosclerosis and calcification near the origin of the internal mammary artery, with distal flow maintained by collateral branches. The thoracodorsal artery was selected to be the recipient vessel because CT showed that it was of adequate size and was not affected by atherosclerosis. The patient experienced no postoperative complications, and the flap survived with no vascular complications. The breasts were symmetrical at a 6-month follow-up. This case highlights that preoperative vascular imaging modalities may help surgeons avoid using diseased vessels as recipient vessels in free flap breast reconstructions.

Maxillary defects are inherently complex because they generally involve more than one midfacial component. In addition, most maxillary defects are composite in nature, and often require bony support, as well as a mucosal lining for reconstruction. Therefore, midfacial bone and soft tissue defects present a unique challenge because they require a complex arrangement of tissues in a relatively limited space. This might be difficult to achieve only with free osteocutaneous flaps. The use of bone grafts allows greater flexibility in a reconstruction but is limited by graft resorption. We report a case of a patient reconstructed with a lateral arm free flap, iliac bone graft, sagital split ramus osteotomy for the reconstruction of a right maxillary defect zygomatico-maxillary defect caused by a zygomatico-maxillary malignant tumor resection.
