  • The superficial circumflex iliac artery perforator (SCIP) flap is a versatile flap that has been described for various applications, mostly for lower extremity coverage and head and neck reconstructions. However, there are few publications reporting its use for breast reconstruction, mainly because of its low volume availability. In this article, we present the case of a patient who successfully underwent a partial breast and immediate nipple-areola complex (NAC) reconstruction with an SCIP flap. She had been previously reconstructed with an implant after a nipple-sparing mastectomy, but the NAC turned out to be involved with cancer needing further resection. Our goal with this article, is to introduce a novel concept for addressing partial breast and NAC reconstruction and mostly, to illustrate the importance of an adaptable surgical plan based on every individual case emphasizing the versality of microsurgery for breast cancer reconstruction.

  • Reservoir Reconstruction Priority(RRP) model is constituted both possibility and restriction criteria for establishing reconstruction priorities and their subdivisions that can be extracted each priorities from the GIS data and by using AHP as the multi-criteria method, it can extract the weighting parameters each criteria of the model. As such, RRP model appeared to provide reasonable criteria in determining the priority of agricultural reservoirs for reconstruction.

  • Autologous microvascular breast reconstruction is widely accepted as a key component of breast cancer treatment. There are two basic donor sites; the anterior abdominal wall and the thigh/buttock region. Each of these regions provides for a number of flaps that are successfully utilised in breast reconstruction. Refinement of surgical technique and the drive towards minimising donor site morbidity whilst maximising flap vascularity in breast reconstruction has seen an evolution towards perforator based flap reconstructions, however myocutaneous flaps are still commonly practiced. We review herein the current methods of autologous microvascular breast reconstruction.

  • Structure-from-Motion(SfM), Multi-view Stereo(MVS)이 이용되는 3D Reconstruction 과정에서 생성된 3D 포인트 클라우드는 RGB 영상에 기반하여 생성되므로 실제 객체 혹은 Scene 과 달리 point 와 point 간에 존재하는 빈 공간이 발생한다. 이를 개선하기 위하여 3D 포인트 클라우드를 이용하여 3D Mesh 를 복원하는 Mesh Reconstruction 과정을 거치게 된다. 본 논문에서는 Mesh Reconstruction 과정에서 자유공간 지지도에 기반해 수정한 가중치를 이용하는 효율적인 방법을 제안한다. 실험을 통하여 제안한 알고리즘을 이용한 복원 결과가 기존보다 개선됨을 보인다.

  • In this invited paper, numerical reconstruction and pattern recognition using integral imaging are overviewed. The computational integral imaging method reconstructs three-dimensional information at arbitrary depth-levels. Photon-counting nonlinear matched filtering combined with the computational reconstruction provides promising results for the application of low-light level recognition.

  • 족관절 만성 외측 불안정증을 비해부학적인 방법으로 재건한 후에 발생하는 여러가지 문제점들을 해결하기 위하여 해부학적으로 재건하는 여러가지 방법이 보고되었다. 해부학적인 위치로 재건하는 것이 정상 관절 역학과 안정성을 회복하는데 중요하다. 해부학적인 재건 방법의 가장 큰 문제점은 인대를 정상적인 주행 방향으로 재건하는 것이 매우 어렵다는 점인데, 저자는 전거비 인대와 종비 인대가 서로 인접하여 위치하므로 두 인대의 비골측 부착부에 한 개의 터널을 만드는 것이 각각의 인대가 통과 할 별도의 터널을 만드는 것보다 좀 더 해부학적이라고 생각하였다. 이 논문에서는 외측 인대의 해부학적 재건에 필요한 기초 지식을 알아보고 반건양건을 이용한 재건 수술 방법을 소개하였다.

  • Background: The purpose of this study was to investigate the usefulness of quadriceps exercise for improvement of knee extensor muscular function after cruciate ligament reconstruction. Methods: Participate in 18 of patients with cruciate ligament reconstruction, ACL & PCL reconstruction was 9 of patients, respectively. All subjects instructed that quadriceps exercise repeated daily, composed to QSE(quadriceps femoris setting exercise) and SLR(straight leg raises). Knee extensor muscular function was measured before and after quadriceps exercise. Initial test was measured before cruciate ligament reconstruction, and retest was measured 6month after cruciate ligament reconstruction. Results: Knee extensor muscular function significantly increased in both ACL and PCL reconstruction(P<0.05). Conclusion: The results of this study indicated that quadriceps exercise useful for improve knee extensor muscular function in patients with cruciate ligament reconstruction.

  • Background: Condylar dislocation can arise as a complication in patients who required mandibular and/or condylar reconstruction and were operated on with fibula free flap (FFF) using surgical guides designed using simulation surgery. Surgeons should be aware of the complications in these present cases when planning and performing reconstructions as well as predicting prognoses. Cases presentation: Two cases showed condylar dislocation in mandibular reconstruction using a FFF fixed with a reconstruction plate. Three cases showed condylar dislocation in mandibular reconstruction using a fibula free flap fixed with a mini-plate. Conclusion: Despite the lack of clinical symptoms in these cases following mandibular reconstruction using an FFF, the mandibular condyle was severely displaced away from the glenoid fossa. A surgeon must have sufficient time to consider the use of a long flap with thickness similar to that of the mandible, ways to minimize span and bending, and methods of fixation. The patient, moreover, should be educated on condylar dislocation. Customized CAD/CAM-prototyped temporomandibular condyle-connected plates may be a good alternative even if virtual simulation surgery is to be performed before surgery. These considerations may help reduce the incidence of complications after mandibular reconstruction.
