Septal deviations interfere with the nasal airflow and contribute to the deformities in the external appearance of the nose. An aesthetically and functionally satisfactory correction of severe septal deformities often requires temporary intraoperative removal of the septal cartilage for appropriate remodeling. This article describes septoplasty through dorsal approach for the correction of septal deviation. From March 2001 to April 2004, the author performed septoplasty through dorsal approach for the correction of septal deviations on 45 patients, of whom 22 of whom had nasal obstruction. Open rhinoplasty was used for dorsal approach in all patients and operation was performed under the general anesthesia or local anesthesia. The follow-up period of the patients ranged from 3 to 15 months with a mean of 10 months, and postoperative results were quite satisfactory. There was neither incidences of patients' complaints, nor any complications such as hematoma, septal perforation, supratip deformity, or recurrence. And there was some improvement of nasal obstruction in 15 patients. In conclusion, Septoplasty through dorsal approach is an effective method for the correction of septal deviation and improvement of the nasal airway obstruction.

It is difficult to obtain a satisfactory bony union of large bone defect secondary to trauma, tumor resection, congenital pseudarthrosis of tibia and bony metaplasia following infection with conventional methods. Conventional nonvascularized autologous bone graft do not provide adequate large amounts of donor bone and usually undergo necrosis or nonunion due to lack of vascular nutrition. Currently, advanced in microsurgery have made it possible to provide a continuing circulation of blood in bone grafts so as to ensure viability. With the nutrient blood supply preserved, healing of the graft to the recipient bone is facilitated without the usual replacement of the graft by creeping substitution. Thus, the grafted bone is achieved more rapid stabilization without sacrificing viability. We reviewed 11 cases of vascularized fibular grafts which were performed from December 1982 to January 1993 and the following results were obtained: 1. Large bone defects with chronic osteomyelitis secondary to trauma were could be successfully treated by the vascularized fibular transfer. 2. In our experience, the vascularized fibular transfer was thought to be one of good methods of treatment for congenital pseudathrosis of tibia. 3. Complete tumor resection was followed by a free vascularized fibular transfer, resulting in good functional improvement, without local recurrence. Long bone defect secondary to bony dysplasia was could be reconstructed by the vascularized fibular transfer. 4. The transferred vascularized fibula had been hypertrophied with bony union during follow-up period and there was no resorption of the grafted fibula.

Northern Gyeonggi Province(NGP), consisting of 3 counties, is the northernmost region in South Korea adjacent to the de-militarized zone with North Korea. To supplement insufficient spatial coverage of official climate data and climate atlases based on those data, high-resolution digital climate models(DCM) were prepared to support weather- related activities of residents in NGP Monthly climate data from 51 synoptic stations across both North and South Korea were collected for 1981-2000. A digital elevation model(DEM) for this region with 30m cell spacing was used with the climate data for spatially interpolating daily maximum and minimum temperatures, solar irradiance, and precipitation based on relevant topoclimatological models. For daily minimum temperature, a spatial interpolation scheme accommodating the potential influences of cold air accumulation and the temperature inversion was used. For daily maximum temperature estimation, a spatial interpolation model loaded with the overheating index was used. Daily solar irradiances over sloping surfaces were estimated from nearby synoptic station data weighted by potential relative radiation, which is the hourly sum of relative solar intensity. Precipitation was assumed to increase with the difference between virtual terrain elevation and the DEM multiplied by an observed rate. Validations were carried out by installing an observation network specifically for making comparisons with the spatially estimated temperature pattern. Freezing risk in January was estimated for major fruit tree species based on the DCMs under the recurrence intervals of 10, 30, and 100 years, respectively. Frost risks at bud-burst and blossom of tree flowers were also estimated for the same resolution as the DCMs.

Purpose: Eccrine porocarcinoma is a very rare, potentially fatal tumor which arises from the intraepidermal portion of the eccrine sweat ductal apparatus. It does not have a characteristic clinical feature but does have a high incidence of metastasis. It may be developed de novo or in a preexisting benign eccrine poroma. It usually affects older people and is located most commonly on lower extremities. We report a rare case of eccrine porocarcinoma which developed on the back without metastasis. Methods: The patient was a 94-year-old woman who showed a painful, ulcerated, dark brown colored polypoid $3.5{\times}3.0cm$ sized mass on the back for 3 years. We totally excised the lesion including normal tissue. Results: After wide excision of the lesion, pathologist reported an eccrine porocarcinoma. Histopathologic findings reveal that the classic type of eccrine gland carcinoma, eccrine porocarcinoma. Immunocytochemical studies showed a positive reactivity to anti-EMA antibody and anti-CEA antibody. Conclusion: Authors experienced a rare case of primary eccrine porocarcinoma on the back. Because of the propensity to develop local recurrence, wide excision of the primary tumor with histologic confirmation of negative margins represents the only curative treatment regimen for eccrine porocarcinoma.

Background : Immediate breast reconstruction after mastectomy and delayed breast reconstruction with post-supplementary treatment are the two types of breast reconstruction currently performed when treating breast cancer. Post-mastectomy radiation therapy (PMRT) not only reduces local recurrence but also improves overall survival. However, the complications and survival rates associated with PMRT need to be clear when determining the timing of breast reconstruction. Accordingly, we investigated the optimal timing of breast reconstruction by observing patients who underwent mastectomy followed by PMRT, based on their overall health and aesthetic satisfaction. Methods : We retrospectively reviewed 21 patients who underwent breast reconstruction with PMRT between November 2004 and November 2010. We collected data regarding the various methods of mastectomy, and the modality of adjuvant therapy, such as chemotherapy, hormone therapy, and radiotherapy. Telephone interviews were conducted to study the general and aesthetic satisfaction. Results : Patients who received PMRT after breast reconstruction showed a greater complication rate than those undergoing breast reconstruction after PMRT (P=0.02). Aesthetic satisfaction was significantly higher in the groups undergoing breast reconstruction after PMRT (P=0.03). Patients who underwent breast reconstruction before PMRT developed complications more frequently, but they expressed greater aesthetic satisfaction with the treatment. Conclusions : It is recommended that the complication rates and aesthetic satisfaction after breast reconstruction be carefully considered when determining the optimal timing for radiotherapy.

Purpose: To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. Materials and Methods: The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. Results: Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. Conclusion: Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.
