  • Ebstein anomaly is a rare congenital heart malformation typically involving the tricuspid valve and the right ventricle that has a wide range of anatomical and pathophysiological presentations. Various surgical repair techniques for Ebstein anomaly have been reported because of its near-infinite anatomical variability. Cone repair for Ebstein anomaly can achieve nearly anatomical reconstruction of the tricuspid valve with promising outcomes. In this article, the surgical techniques for cone repair in adult patients with Ebstein anomaly are described in detail, and clinical experiences and technically challenging cases are presented.

  • The challenges of successful nasal reconstruction, which are related to the anatomical complexity of the region, have been extensively studied. Revisional operations are often required to achieve proper nasal reconstruction, with results resembling the premorbid nasal status. This is necessary to ensure the quality of life of skin cancer patients. Fundamental nasal reconstruction requires both proper soft tissue coverage and proper function. However, earlier studies in the field primarily focused on the functional aspect of nose reconstruction, although the cosmetic aspect is also an important factor to consider. In response to this need, many recent studies on nose reconstruction have proposed various refinement strategies to improve aesthetic satisfaction. Most plastic surgeons accept the nasal aesthetic subunit principle as a standard for nasal reconstruction. This review outlines the commonly used surgical refinement options and management strategies for postoperative complications based on the subunit principle. In patients with nasal defects, a proper technical strategy might help minimize revision operations and optimize the long-term results.

  • In order to create three-dimensional model for human body, a method that reconstructs geometric models from contour lines on cross-section images is commonly used. We can get a set of contour lines by acquiring CT or MR images and segmenting anatomical structures. Previously proposed method divides entire contour line into simply matched regions and clefts. Since long processing time is required for reconstructing cleft regions, its performance might be degraded when manipulating complex data such as cross-sections for human body. In this paper, we propose a fast reconstruction method. It generates a triangle strip with single tiling operation for simple region that does not contain branch structures. If there exist branches in contour lines, it partitions the contour line into several sub-contours by considering the number of vertices and their spatial distribution. We implemented an automatic surface reconstruction system by using our method which reconstructs three-dimensional models for anatomical structures.

  • The anterolateral thigh flap(ALT flap) was originally described in 1984 as a septocutaneous nap based on the descending branch of the lateral circumflex artery. This nap has some significant advantages for reconstruction of the head and neck. It can be raised as a subcutaneous flap, a fasciocutaneous nap, or a myocutaneous nap and can resurface large defects in the head and neck. In addition, it has a large and long vascular pedicle, and because of the distance of the donor site from the head and neck, it can easily be harvested with a two-team approach. However, the number and locations of cutaneous perforators vary individually, and thus, it is not widely used because nap elevation is often complicated and time-consuming owing to unexpected anatomical variations. The purposes of this study are to clarify the vascular anatomy and to assess the suitability of anterolateral thigh nap for oral cavity reconstruction in Koreans. In addition, we used anterolateral thigh free nap for oral cavity reconstruction in 20 oral cancer patients from 2006 to 2011. Through our clinical experience, we discuss a series of practical "pearls and pitfalls". Our experience has not only given us new flap choice using anterolateral thigh nap in oral cavity reconstruction, but also given us a new possibility on the applicability of chimeric naps.

  • Peroneal tendon disorders are one of many causes of chronic lateral ankle pain. They are related to chronic conditions and anatomical factors and can cause persistent pain and functional impairment if neglected. Peroneal tendon tears are frequently misdiagnosed due to the absence of clear symptoms. For subacute or chronic peroneal tendon ruptures, tendons often became irreparable, and hence various surgical options have been introduced to address this issue. Current surgical treatment options include debridement and tubularization, tenodesis, tendon transfer, and reconstruction with a graft. There have been a few reports on the use of reconstruction techniques with an allograft. In this report, we present a rare case of a peroneal tendon reconstruction technique using an allograft in a young male with simultaneous irreparable peroneus longus and a complete rupture of the brevis tendon. The management plan, prognostic outlook, and a subsequent review of the relevant literature are also presented.

  • The anterolateral thigh flap (ALTF) is a versatile fasciocutaneous or myocutaneous flap, which can be harvested incorporating several skin islands and muscle components. The perforator of the ALTF is usually derived from the descending or transverse branch of the lateral circumflex femoral artery, and these vessels are based mainly on musculocutaneous perforators traversing the vastus lateralis muscle, and also based on the septocutaneous vessels running in between the rectus femoris and vastus lateralis muscle. Despite its usefulness for the oral cavity reconstruction, anatomic variations of these nutrient vessels, such as three main branches of ALTF and its relations with sartorius, vastus lateralis, tensor fasciae latae and rectus femoris muscle, have been reconstructive surgeons to be hesitated for the selection of ALTF. For the better understanding of ALTF as a routine reconstructive procedure in oral and maxillofacial surgery, various anatomical findings must be learned and memorized by young doctors in the course of the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article will discuss the vascular anatomy and relavant anatomical variations of ALTF with Korean language.

  • The latissimus dorsi myocutaneous flap (LDMF) was initially described at the turn of the century by Tansini et al, and latissimus dorsi myocutaneous free flap (LDMFF) was also first described for the coverage of a chronically infected scalp by Maxwell et al. As a pedicled flap, LDMF has been often used for breast reconstruction and for soft tissue replacement near the shoulder and the lower reaches of the head and neck. LDMFF is a flat and broad soft tissue flap with large-caliber thoracodorsal vessels for microvascular anastomosis. A skin paddle of the LDMFF can be more than $20{\times}40$ cm, so very large defects in the oral cavity and outer facial region can be covered by this LDMFF. Other advantages include consistent vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with tumor resection. For a better understanding of LDMFF as a routine reconstructive procedure in large defects of the oral cavity and facial legion, 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 LDMFF with Korean language.

  • Midfacial reconstruction following resection of extensive malignant oral cavity tumors constitutes a challenging problems for reconstructive surgeons. Rectus abdominis muscle free flap (RAMFF) can be considered as the optimal reconstructive option in this case, because this flap has some advantages including consistent deep inferior epigastric artery anatomy, easy to dissect with well defined skin boundaries, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with oral cancer ablation surgery. The rectus abdominis muscle forms an important part of the anterior abdominal wall and flexes the vertebral column, which is a long strap-like muscle divided transversely by three tendinous intersections, fibrous bands which are adherent to the anterior rectus sheath, which is thickly enclosed by the rectus sheath, except for the posterior part below the arcuate line that is usually located midway between the umbilicus and symphysis pubis. Below the arcuate line, this muscle lies in direct contact with the transversalis fascia and parietal peritoneum. For the better understanding of RAMFF as a routine reconstructive procedure in oral and maxillofacial surgery, the constant anatomical findings muse be learned and memorized by the young doctors in the course of the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article will discuss the anatomical basis of RAMFF with Korean language.

  • Injury of posterolateral corner is unusual, but it can cause disability due to severe instability and cartilage damage. However, the anatomical structures, diagnosis and treatment have not defined clearly yet. Posterolateral corner injury is regarded as the one of main factor to the results of failure in cruciate ligament reconstcution if it was undiagnosed and untreated. Diagnosis of postetolateral corner injury is consists of physical exam, radiographic finding, MRI, and arthroscopic findings. The treatment method of of postetolateral corner injury depends on the time and severity of injury. Anatomical reconstruction of posterolateral corner shows the better clinical outcome than non anatomical reconstructions, but the clinical results of long term follow up is still needed. Therefore, the aim of this article is to review the recent literatures and to organize diagnosis and treatment of posterolateral corner injury.
