  • Large and ptotic breast reconstruction in patients who are not candidates for a transverse rectus abdominalis myocutaneous flap and revision surgery for the contralateral breast remains challenging. We developed a novel breast reconstruction technique using a latissimus dorsi myocutaneous (LD m-c) flap set at the posterior aspect of the reconstructed breast, combined with an anatomical silicone breast implant (SBI), following tissue expander surgery. We performed the proposed technique in four patients, in whom the weight of the resected tissue during mastectomy was >500 g and the depth of the inframammary fold (IMF) was >3 cm. After over-expansion of the lower portion of the skin envelope by a tissue expander, the LD m-c flap was transferred to cover the lower portion of the breast defect and to achieve a ptotic contour, with the skin paddle set at the posterior aspect of the reconstructed breast. An SBI was then placed in the rest of the breast defect after setting the LD m-c flap. No major complications were observed during the follow-up period. The proposed technique resulted in symmetrical and aesthetically satisfactory breasts with deep IMFs, which allowed proper fitting of the brassiere, following large and ptotic breast reconstruction.

  • The purpose of this study was to aid in the evaluation of prognosis of temporomandibular joint following orthognathic surgery. For this study, 20 patients (40 TMJ) who undergone orthognathic surgery were examined. Preoperative and postoperative tomograms of TMJ were taken. And the subjects were divided into 3 groups according to postoperative periods. The obtained results were as follows; 1. There were no significant differences between preoperative and postoperative changes in joint spaces in each group and between groups(P<0.05). 2. There were no significant differences between preoperative and postoperative ratio of joint space(P<0.05). 3. There were no significant differences between preoperative and postoperative changes in the range of motion of condylar head(P<0.05). 4. The bony changes of condylar head were observed in 14(35%) condyles (6 erosion, 2 flattening, 5 double contour, 1 osteophyte).

  • This paper aims to discussion the characteristics of location and spatial organization on Hongneung and Yureung(royal tomb) in Namyangju through the interpretation of traditional oriental philosophy including Feng-Shui theory. To do this, we studied in two ways; analysis of the present conditions and photographing research materials about the form of physical structure and review of historical document. The result of analysis in sight of the location and spatial structure was good matched. Main finding of this paper are as follows: The location and landscape structure was characterized by the harmony with natural following traditional thinking and the Korean view of nature, while maintaining the dignity of the King. The spatial organization were placed in a straight line following the hierarchy of metaphysics by order of Neungchim(Tombs Vicinity) - Changmyungdeung(Stone Lantern) - Chungjakak(Pavilion) - Hongsalmun(Gate for Heavenly Gods) and was based on the Confucianism value, the natural contour and inner value. Through this study, we find the principles made it possibles to re-evaluate nature in modem society and provided us with new ways to conserve nature with the help of environmental theory.

  • Background Abdominoplasty, with or without liposuction, is among the most frequently performed aesthetic procedures. Its main objective is to improve the body contour by means of excising redundant skin and fat tissue. Although abdominoplasty is considered a safe procedure with high satisfaction rates, intraoperative and postoperative complications can become a challenge for the surgical team. The aim of this article is to offer a synopsis of the most common complications arising after abdominoplasty, along with evidence-based guidelines about how to prevent and treat them. Methods A systematic MEDLINE search strategy was designed using appropriate Medical Subject Headings (MeSH) terms, and references were scanned for further relevant articles. Results According to the published case series, local complications are considerably more common than complications with systemic repercussions. Approximately 10% to 20% of patients suffer a local complication following abdominoplasty, while fewer than 1% suffer a systemic complication. Prevention and management strategies are critically discussed for complications including seroma, haematoma, infection, skin necrosis, suture extrusions, hypertrophic scars, neurological symptoms, umbilical anomalies, deep venous thrombosis and pulmonary thromboembolism, respiratory distress, and death. Conclusions The complications of abdominoplasty vary in severity and in the impact they have on the aesthetic outcomes. Recommendations for prevention and management are based on various levels of evidence, with a risk of observer bias. However, most complications can be treated appropriately following the current standards, with satisfactory results.

  • Mandible angle ostectomy is the most widely-operated facial contour surgery. We experienced a rare case of necrotizing fasciitis of the lower leg following mandible angle ostectomy. A 20 years old female visited our department 5 days after mandible angle ostectomy. At the time, she was diagnosed as sepsis and on her 2nd admission day, she was diagnosed as necrotizing fasciitis on her left leg. She was treated by fasciotomy and necrotized tissue removal. Necrotizing fasciitis is a rare complication of any kinds of operation but once it develops, it causes fatal results, especially to cosmetic surgeries. Early diagnosis and aggressive operation is known as only treatment for the disease.

  • Lupus panniculitis (LP) often presents with tender nodules and intermittent ulcers that then heal with scarring and lipoatrophy. The current mainstay of treatment is medical treatment. Research regarding the treatment of lipoatrophy from LP with autologous fat grafting is limited. We would like to share our experience in this rare case, which was treated with autologous fat transfer. A 48-year-old female presented with erythematous plaque, tender nodules, and ulcers following by a depression of the lesion at the left temporal area. The patient also had indurated erythematous plaque at her left cheek. Both lesions were aggravated by sunlight exposure. After several investigations, she was diagnosed as LP with secondary lipoatrophy and tumid lupus erythematosus at her left temporal and left cheek, respectively. She received antimalarial drug and topical steroids. The patient underwent two sessions of autologous fat transfer. She was satisfied with the volume and contour improvement in the scar following the injection of 8 and 3.7 mL of fat. Furthermore, the patient reported the remission of tender nodules and ulcers since the first fat graft injection. In conclusion, the autologous fat transfer is a simple and effective treatment for lipoatrophy and scar secondary to LP with promising results.

  • STATEMENT OF PROBLEM: Interpoximal papilla could be re-established without immeidate support with a provisional resotration following an immdiate implant placement. PURPOSE: Successful esthetic outcomes were reported utilizing immediate provisionalization following immediate implant placements. The aim of this study was to evaluate the soft tissue esthetics around immediately placed single tooth implant restorations with or without immediate provisional restorations. METHODS: A total of ten patients, who had a hopeless maxillary anterior tooth, were enrolled in this study. Screw retained provisional restorations were delivered to the randomly chosen 5 patients (immediate provisionalization group) on the day of immediate implant placement and maintained for about 5 months. For the remaining five patients (non-immediate provisionalization group), healing abutments were delivered on the day of surgery, replaced with screw retained provisional restorations approximately 3 months afterwards, and the provisional restorations were maintained for about 3 months. Digital photographs were taken at the delivery of final restorations in order to assess following variables; mesial papilla, distal papilla, soft tissue level, soft tissue contour and facial soft tissue prominence. The variables were compared to those of the contralateral natural tooth and scored by prosthodontists, periodontists, orthodontists and dental students. RESULTS: The immediate provisionalization group marked significantly higher scores on the following variables; soft tissue level and facial soft tissue prominence. In evaluating each variable, there were no notable differences in opinion between four dentist groups. CONCLUSION: Immediate provisionalization can be a treatment option to achieve superior soft tissue esthetics around immediately placed single implant restorations rather than non-immediate provisionalization approaches.

  • An overall reduction in the horizontal and vertical dimensions occurs following tooth extraction and the resorption of the buccal part of the ridge is more pronounced than the lingual part. Thus, the resulting morphology of the healed alveolar ridge is often presenting with a discrepancy in bone height between the buccal and lingual aspects of the ridge. The implant with a sloped marginal configuration that is designed to match the sloped contour of the alveolar ridge provides the opportunity to maintain the buccal-lingual bone discrepancy and soft tissue around the implant. This paper introduces the OsseoSpeed TX Profile implants with sloped marginal configuration and explains the characteristics and clinical meanings of those implants.

  • This study was undertaken to investigate the values of the cephalometric standards of Korean children which consisted of 57 boys and 61 girls with normal occlusion and harmony of the facial musculature. The following conclusions were obtained. 1) The relatively vertical inclination of nasal bone and flat contour of the frontal bone contribute to the flattening of the upper face. 2) Slight lack of chin prominence characterizes the lower face while procumbent incisors and their alveolar bone dominate the middle face. 3) A caudal skull base inclination is probably the most specific feature for Korean.
