Our hospital have started laparoscopic cholecystectomy in 1991, and after then many surgeons have been trained in the era of laparoscopic and minimally invasive surgery. Since then numerous procedures have been applied for a laparoscopic surgery, and many patients have been benefited as a result. We have performed the first automated surgery in Korea using Automated Endoscopic System for Optimal Positioning (AESOP) in June, 1996. With the help of Inbae Yoon’s(a 1961 graduate of our medical school) inspiration and donation, our hospital has started “IB Yoon Multi-Specialty Endoscopic Research & Training Center” in 1998. As we started the robotic surgery we have change the name to “Severance Robotic and Minimally Invasive Surgery Center” in March 2005. These infrastructures enables us the expansion of laparoscopic surgery and inspires many surgeons to understand principles and equipments of laparoscopic and robotic surgery. We performed the first robotic surgery using da Vinci system in July, 2005. During 5 and half years after introducing the da Vinci surgical system in 2005 we have performed more than 10000 cases of robotic surgery successfully. With collaboration between medicine and robotic engineering company, we are developing our own version of Korean robotic system. In conventional laparoscopic surgery, limited motion of laparoscopic instruments, 2-D surgical field, and unstable surgical view resulted from unnecessary movement of laparoscope (shaking surgical field) by assist surgeons, magnifying tremor of laparoscopic instrument, and unexpected movement of laparoscopic instrument by another assist-surgeon can accidentally produce inappropriate environment for safe laparoscopic surgery. To the contrary, stable 3-D surgical field provided by robot surgical system, wrist like movement of instrument, stationary holding of fourth arm movement (to replace the role of assistant surgeon in laparoscopic surgery) seems to produce very appropriate surgical environment for safe laparoscopic HBP surgery. Therefore, robot is thought to be very appropriate for function-preserving minimal invasive HBP surgery.

OBJECTIVE: The purpose of this study was to investigate the changes in dentofacial morphology of non-orthodontically treated female patients with TMJ disk displacement. METHODS: The sample consisted of 25 Korean female patients with bilateral TMJ disk displacement who visited the Department of Orthodontics, Seoul National University Dental Hospital from 1996 to 2006. Disk displacements were diagnosed using the magnetic resonance imaging (MRI) of both TMJs. Baseline (T1) and follow-up (T2) lateral cephalograms were analyzed. The mean age of samples at T1 was 18.1 +/- 3.5 years (range 14.2 - 25.8 years) and at T2, 21.1 +/- 3.5 years (range 16.2 - 28.0 years). The mean observation period was 3.0 +/- 1.9 years. Descriptive statistics for each variable were calculated at baseline (T1) and follow-up (T2) stages, and during the observation period (T2-T1). RESULTS: Skeletal changes were found in 64% of the non-orthodontically treated female patients with TMJ disk displacement during the observation period. The L1 to Mandibular plane distance (mm) increased significantly by 0.8 mm (p < 0.01). But there were no significant differences in the other dental relationship variables (overjet, overbite, U1 to palatal plane) during the observation period. Most patients with skeletal changes showed a backward rotation of the mandible. The ratio of the rotation was a decrease of SNB by 0.43degrees for every 1degrees increase of FMA (Spearman rho = -0.660, p < 0.01). A few patients showed a distal shift of the mandible without rotation or significant changes in the vertical dimension. CONCLUSIONS: During observation periods without orthodontic treatment, non-growing patients with TMJ disk displacement showed dentoskeletal changes, mainly backward rotation of the mandible.

The goal of reduction mammaplasty is a breast with natural contour and volume, aesthetically situated scars, and a well-placed, sensate nipple and areola. The most successful techniques achieve this through the excision of tissue from the lower part of the breast based on some variation. However, the Mckissock's vertical bipedicle technique is the popular method for reduction mammaplasty. As an alternative modified Mckissock's method, we have found the use of only an inferior dermal flap with a keyhole pattern to be a simple and safe method for obtaining satisfactory aesthetic results. We have used inferior dermal flap for 4 patients recently and obtained the advantages as below compare to the Mckissock's method. 1. Rich blood supply to the broad based inferior flap. 2. More easy transposition of the nipple and areola. 3. More good operation field for resection of breast tissue. 4. Short operation time. 5. Can applied to the gigantomastia.

BACKGROUND: The proportion of patients with subacute cutaneous lupus erythematosus(SCLE) is considered to be 10% among the total LE population in western countries. The morphology of LE-specific skin lesions in SCLE : appear as papulosquamous erythema or annular erythema developing mostly on the exposed areas. Among Korean patients with LE the prevalence and the pattern of cutaneous eruption of SCLE may be different from those patients of western countries. OBJECTIVE: To obtain the prevalence and the morphological characteristics of cutaneous lesions in Korean patients with SCI E v;ere the main objectives. METHODS: With 7 cases of SCLE, clinical dermatologic examinations for the character, the distribution, and the clinical course of those cutaneous lesions, and for the extent of systemic symptoms and LE-related laboratory abnormalities in each patient were performed. Results/Coeclusion. The prevalence of SCLE among Korean patients with LE or latent LE was much lower than those seen in Caucasians. The pattern of cutaneous lesions were papular/ papulosquamous erythemas with no (or rare) cases of annular erytherna among those patients diagnosed as SCLE. ~Other cl~inica! features were similar to Caucasian patients. It seems that there are some racial differences in the cutaneous manifestat.ions of LE, which may be relevant to the dissimilarities in immunogenetic backgrounds between different racial groups.
