Bicoronal approach is adopted as an universal method for reduction and internal fixation of the fractured zygomatic arch in the treatment of complex zygomatic fracture. However bicoronal approach leaves many disadvantages, such as long incision, alopecia, prolonged edema, and paresthesia. Nowadays endoscopically assisted minimal invasive technique has been widespread not only for the aesthetic surgery, but also for the reconstructive surgical fields because of the benefits. We have been recently trying to apply endoscopic surgery to facial bone fracture surgery. Endoscopically assisted minimal invasive technique has been applied to 14 patients who admitted to Chosun university hospital from March 1996 to July 1997. We used 4 mm, 30' endoscope and two 1.5-2 cm temple incisions and a subciliary incision for approaching to the zygomatic arch. Protected drill bit and driver had access to fractured zygomatic arch though tiny(5 mm) stab incision over the zygomatic arch. We have been able to successfully reduce and make fixation of the fracture of zygomatic arch by using endoscopically assisted minimal invasive technique. Follow up for 3 months revealed good maintenance of the reduction. We think that application of the endoscopic technology to midfacial bone fracture will result in significant reduction in morbidity and improve postoperative results.

Recent studies have demonstrated that the patients with psoriasis have various immune alternation in both humoral and cellular immunities. However the results of these are still controversial. These facts promoted us to analyze the immune cells (T cell, T subsets and B cell) by rosette method for these cells in peripheral blood of 15 patients with psoriasis. And we also analyzed the effects of photo- chemotherapy(PUVA) on these cells. The results were summerized as follows; 1. The mean values of T cell, T, T, cell and B cell in peripheral blood of the- patients with psoriasis before PUVA therapy were 56. 2+-5.7%, 35.1+-6.9%, 5. 5+l.4%, 11.6+4. 0% respectively, These results of immune cells showed signi- ficantly lower mean values when these were compaired with the mean values. of nomnal control group(T cell; 65. 2+-2.9%, TM cell; 45.8+-3.2%, T cell; 7.3+ 1.3% B cell; 16.2+2.4%), respectively (T cell, Tm Tg, p<0.01, B cell; p<0.05). 2. The mean values of T cell, T, T, cell and B cell in peripheral blood (countinue..)

PURPOSE: To evaluate the treatment outcome and prognostic factor of postoperative radiotherapy for extremity soft tissue sarcoma (STS). MATERIALS AND METHODS: Forty three patients with extremity STS were treated with conservative surgery and postoperative radiotherapy from January 1981 to December 2010 at Korea University Medical Center. Median total 60 Gy (range, 50 to 74.4 Gy) of radiation was delivered and 7 patients were treated with chemotherapy. RESULTS: The median follow-up period was 70 months (range, 5 to 302 months). Twelve patients (27.9%) sustained relapse of their disease. Local recurrence occurred in 3 patients (7.0%) and distant metastases developed in 10 patients (23.3%). The 5-year overall survival (OS) was 69.2% and disease free survival was 67.9%. The 5-year local relapse-free survival was 90.7% and distant relapse-free survival was 73.3%. On univariate analysis, no significant prognostic factors were associated with development of local recurrence. Histologic grade (p = 0.005) and stage (p = 0.02) influenced the development of distant metastases. Histologic grade was unique significant prognostic factor for the OS on univariate and multivariate analysis. Severe acute treatment-related complications, Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4, developed in 6 patients (14.0%) and severe late complications in 2 patients (4.7%). CONCLUSION: Conservative surgery with postoperative radiotherapy achieved a satisfactory rate of local control with acceptable complication rate in extremity STS. Most failures were distant metastases that correlate with tumor grade and stage. The majority of local recurrences developed within the field. Selective dose escalation of radiotherapy or development of effective systemic treatment might be considered.

BACKGROUND: This study aimed to assess the recent changes of radiation therapy (RT) modalities in Korea. In particular, we focused on intensity-modulated radiation therapy (IMRT) utilization as the main index, presenting the application status of advanced RT. METHODS: We collected information from the Korean Health and Insurance Review and Assessment Service data based on the National Health Insurance Service claims and reimbursements records by using treatment codes from 2010 to 2016. We classified locating region of each institution as capital vs. non-capital areas and metropolitan vs. non-metropolitan areas to assess the regional difference in IMRT utilization in Korea. RESULTS: IMRT use has been steadily increased in Korea, with an annual increase estimate (AIE) of 37.9% from 2011 to 2016 (P < 0.001) resulting in IMRT being the second most common RT modality following three-dimensional conformal radiotherapy. In general, an increasing trend of IMRT utilization was observed, regardless of the region. The rate of AIE in the capital areas or metropolitan areas was higher than that in non-capital areas or non-metropolitan areas (40.7% vs. 31.9%; P < 0.001 and 39.7% vs. 29.4%; P < 0.001, respectively). DISCUSSION: The result of our survey showed that IMRT has become one of the most common RT modalities. IMRT is becoming popular in both metropolitan and non-metropolitan areas, while metropolitan area has faster AIE possibly due to concentration of medical resources and movement of advanced patients.

Purpose: To explore the clinical characteristics and profiles of newly diagnosed glaucoma subtypes in urban Korea. Methods: All newly diagnosed glaucoma patients enrolled in the participating ophthalmology outpatient clinics were in-cluded. A review of medical history including family history of glaucoma was conducted. The patients underwent complete ophthalmologic examinations including visual field test. The diagnosis of glaucoma was based on the International Society of Geographical and Epidemiological Ophthalmology criteria developed by glaucoma specialists. Results: A total of 198,671 patients visited the participating ophthalmology outpatient clinics during the study period (from January 1, 2001 to June 30, 2016), of which 5,530 (2.8%) were diagnosed with glaucoma. The mean age of the newly diag-nosed glaucoma patients was 52.0 ± 17.3 years (range, 6 to 89) and 2,830 patients were male (51.2%). The mean untreated in-traocular pressure and vertical cup-to-disc ratio of the optic nerve head of newly diagnosed glaucoma eyes were 22.1 ± 10.6 mmHg and 0.66 ± 0.22, respectively. The most frequently observed subtypes of glaucoma were: normal tension glaucoma (33.0%) primary open-angle glaucoma (28.4%), ocular hypertension (11.1%), chronic angle-closure glaucoma (6.8%), neovas-cular glaucoma (5.2%), glaucoma associated with inflammation (3.8%), acute angle-closure glaucoma (3.3%), and glaucoma associated with aphakia or pseudophakia (2.2%). Conclusions Normal tension glaucoma was the most frequently observed glaucoma subtype in urban ophthalmology outpa-tient clinics in Korea.

Chordoid glioma is a rare, low-grade brain neoplasm typically located in the third ventricle. Herein, we report an unusual case of histologically confirmed chordoid glioma located in the pituitary fossa and suprasellar region, not attached to the third ventricle. A 57-year-old woman presented with a 2-month history of headache and visual disturbance. Magnetic resonance imaging revealed an ovoid mass in the pituitary fossa and suprasellar region, compressing the optic chiasm without involvement of the third ventricle. The tumor showed low signal intensity on T1-weighted images and iso- to high signal intensity on T2-weighted images, with strong and homogenous contrast enhancement. Subtotal resection was performed via the transcranial approach, and the patient subsequently received adjuvant gamma knife radiosurgery. However, the residual mass showed disease progression 5 months after the initial surgery.

BACKGROUND: Inguinal herniorrhaphy remains one of the most common general surgical operations. Mesh repair is advocated by several specialized hernia centers. The purpose of this study was to compare results of mesh and Shouldice repair for inguinal herniae. METHODS: A clinical review was made of 73 cases of inguinal herniae treated during the 3 years from January 1993 to December 1996 at the Department of Surgery, Dae Rim Saint Mary's Hospital, and at the Department of Surgery, Eum Sung Saint Mary's Hospital. We treated 38 patients with mesh repair and 35 patients with a Shouldice procedure. Among 73 cases, 72 cases were males and only one case was a female. All except 8 cases had indirect types of hernias. RESULTS: Mesh repair required less time (80 minutes) and was an easier operative technique than the Shouldice procedure (95 minutes), but postoperative pain was similar between the two procedures. Postoperative pain was relieved after one week in 60% of the patients and after four weeks in 88% of the patients. The complications following the operations were similar between the two procedures: voiding difficulties developed in two cases, wound infection in one case, and a hematoma in two cases. There were no recurrences during the 6 month to 3 year follow up. CONCLUSIONS: Inguinal herniorrhaphy using a mesh repair technique provides is simple, rapid, less painful, and effective.

The purpose of this study is to develop new standards for the disability evaluation with reference to existing laws and other study reports regarding disabilities for the rational evaluation of the diverse kinds of disfigurement in appearance and skin. Three plastic surgery specialists and 3 dermatology specialists developed a new standard for the disability evaluation which is appropriate for circumstances in Korea. Disability rate does not take into account the social occupation, gender or age of the patient, but instead, evaluate the Activity of Daily Living and the social adaptability of the appearance and skin disfigurement regardless of the balance between different disabilities. We tried to include most cutaneous disorders and categorized them into 3 types; congenital (Type 1), acquired (Type 2) as well as any permanent skin impairment sequelae of disease, trauma or treatment process (Type 3). For type 3 disorders, we tried to rate the score according to the size of involved skin lesion. The disability rate is determined by dividing the disability class into 8 steps based on the seriousness of each type of disability.
