  • This study tried to reveal incision rate distribution of streams on the northern part of the Sobaek Mountain Range with OSL age dating and geomorphic analysis, and factors influencing on the distribution were also discussed. With results from the previous studies, a total of 10 sites from 7 streams in the study area showed the rates ranging from 0.220 m/ka to 0.297 m/ka. Namhan-gang and Geum-cheon indicated the highest and lowest rates, respectively. Both sides in the northern section in the study area showed similar rates, while the western side in the middle section and the eastern side in the southern section showed higher rates than the other sides. Higher rates were also found from the eastern and northern sides where the Range runs N-S and E-W directions, respectively. Certain relationships with altitude and distance from the divide can be recognized from the rates and may be attributed to active incision with altitude and location of the uplift axis near the present divide. The rates on granite and sedimentary rock were higher than those on metamorphic rock, indicating that bedrock type is one of the important factors influencing on stream incision. Tectonic movement seemed to play some roles in the rates, because areas with lineaments showed lower rates. This study suggests that incision rate distribution of streams on the northern part of the Sobaek Mountain Range reflects various local geomorphic and geologic conditions.

  • Background Descent of the lateral aspect of the brow is one of the earliest signs of aging. The purpose of this study was to describe an open surgical technique for lateral brow lifts, with the goal of achieving reliable, predictable, and long-lasting results. Methods An incision was made behind and parallel to the temporal hairline, and then extended deeper through the temporoparietal fascia to the level of the deep temporal fascia. Dissection was continued anteriorly on the surface of the deep temporal fascia and subperiosteally beyond the temporal crest, to the level of the superolateral orbital rim. Fixation of the lateral brow and tightening of the orbicularis oculi muscle was achieved with the placement of sutures that secured the tissue directly to the galea aponeurotica on the lateral aspect of the incision. An additional fixation was made between the temporoparietal fascia and the deep temporal fascia, as well as between the temporoparietal fascia and the galea aponeurotica. The excess skin in the temporal area was excised and the incision was closed. Results A total of 519 patients were included in the study. Satisfactory lateral brow elevation was obtained in most of the patients (94.41%). The following complications were observed: total relapse (n=8), partial relapse (n=21), neurapraxia of the frontal branch of the facial nerve (n=5), and limited alopecia in the temporal incision (n=9). Conclusions We consider this approach to be a safe and effective procedure, with long-lasting results.

  • Acute compartment syndrome of the lower leg and foot is a surgical emergency. The clinical symptoms is an important clue to diagnose compartment syndrome. In cases of ambiguous diagnosis, unconscious patients and children additionally need a intracompartmental pressure measuring. Immediate fasciotomy should be performed when clinical signs are obvious or when delta pressure is less than 30 mmHg or intracompartmental pressure is greater than 30 mmHg. Fasciotomy of the lower leg can be performed either by one lateral single incision or double incision, which of the foot mainly has a dorsal or medial incision. A delayed in diagnosis that leads to a delay in treatment can result in devastating disability. Acute compartment syndrome of the lower leg and foot is a relative rare but serious complication of which a surgeon should be aware.

  • From Jan. 1983 to Dec. 1985, seven cases of pectus excavatum, six were male and one female, were underwent an operation at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. The ages of patients ranged from 6 to 27 years. They all had symptoms of feeling inferiority about chest deformity. The concavity on the funnel chest varied in its extent, and the severity, which was measured by water volume filled into it, varied from 59.5cc/m2 to 129.9cc/m2. All but one patients were approached through a bilateral transverse submammary incision and one approached through a vertical midline incision. Successful surgical correction required resection of all deformed costal cartilages with transverse anterior osteotomy and internal fixation using retrosternal metal bar. No serious complication have followed the use of this technique, but minor complications such as serous accumulation, pneumothorax and strut migration have been experienced. All patients were satisfactory about the surgical results.

  • Background: The traditional approach for reduction of frontal sinus fractures is coronal incision. Inherent complications of the coronal approach include long scar, hair loss, and long operation time. We describe a simple approach for the reduction of frontal sinus anterior wall fractures using a suprabrow incision that is commonly used for brow lift. Methods: From March 2007 to October 2016, the authors identified patients with anterior wall frontal sinus fractures treated by open reduction through a suprabrow incision. Only cases with photographic/radiographic documentation and a minimum follow-up of 6 months were included. The incision line was designed to be at the upper margin of the eyebrow. Medical records and radiographic data were retrospectively reviewed. Surgical outcomes, cosmetic results, and complication were assessed. The patient scale of the patient and observer scar assessment scale was used to assess patient satisfaction for incisional scar at the 6-month follow-up. Results: Thirty-one patients underwent fracture reduction through a suprabrow approach during the study period, with a mean follow-up of 41 months. No patients showed any recurrent displacement, eyebrow asymmetry, or infection during follow-up. Thirteen patients reported their forehead paresthesia postoperatively, and 12 of them had preoperative symptom. One patient complained of incisional scar and underwent scar revision. All patients were satisfied with their eyebrow and forehead contour. Conclusion: The suprabrow approach allowed for an accurate reduction of the fractures in the anterior wall frontal sinus by providing direct visualization of the fracture. This transcutaneous approach can effectively restore forehead contour with acceptable postoperative complications and patient satisfaction.

  • Propose: There have been many debates about the ideal surgical technique for acute Achilles tendon rupture. The purpose of this study is to review and analyze the clinical outcome of the acute Achilles tendon ruptures that had been repaired by indirect suture technique with minimal incision that utilized an instrument called Achillon (Newdeal, France). Materials and Methods: This study is based on the 14 cases (14 patients) of acute Achilles tendon total ruptures that have been repaired by minimal incision technique utilizing Achillon instrument from June 2003 to December 2004. Two cases were reruptured before 8 weeks and repaired again using Krackow suture which left 12 feet for postoperative functional evaluation with at least 6 months of follow-up. Ten cases were men and average age at time of injury was 34.4 (26-49) years. The time from injury to surgery was an average of 4.5 (1-9) days and the postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. The ability to return to original work and sports activities as well as patient satisfaction were also evaluated. Results: The follow-up period was averaged for 13.2 (6-24) months. Seventy-one percent of cases were ruptured during sports activities. The ruptured level was the average of 5.1 cm (3.2-8 cm) above calcaneal attachment and the skin incision was averaged for 2.7 cm (2.5-3.0 cm) long. At final follow-up, standing on tip-toe was possible in all cases while the heel-floor height on ruptured side was shorter by 0.7 cm (0-2 cm). By Arner-Lindholm evaluation scale, 9 cases were excellent, and 3 cases were good. Overall AOFAS score was an average of 96.1 (94-100), and all patients were satisfied with the result. Patients returned to work at an average of 1.3 months after the surgery and pre-injury sports activities were all possible from at 6 months after operation. Conclusion: Since we have treated acute Achilles tendon ruptures with minimal incision technique utilizing the Achillon and gained encouraging functional results with all patients returning to previous work with high patient satisfaction, this technique could be recommended as one of the ideal surgical options for the Achilles tendon ruptures.

  • Purpose: Good results using minimal invasive hallux valgus surgery has been reported recently. We evaluate the usefulness of linear distal metatarsal osteotomy with minimal skin incision in mild and moderate hallux valgus deformity. Materials and Methods: Twenty-eight patients (thirty-one cases) who had mild to moderate hallux valgus deformity and underwent linear distal metatarsal osteotomy using minimal skin incision were evaluated between February 2005 and February 2006. Hallux-metatarsophalangeal-interphalangeal scale of AOFAS (American Orthopaedic Foot and Ankle Society) score was used as clinical evaluation. Preoperative, postoperative, after pin removal, and final follow up plain radiographs were used as radiologic evaluation. Results: Twenty-six cases (83%) among thirty-one cases showed more than average satisfaction, Average AOFAS score were improved from 63.2 points (range 45-74 points) to 86.4 points (range 67-93 points). Preoperative radiologic index of IMA $14.0^{\circ}$ (range $10-18^{\circ}$), HVA $30.2^{\circ}$ (range $19-39^{\circ}$), DMAA $13.8^{\circ}$ (range $5-23^{\circ}$) were improved postoperatively as IMA $8.3^{\circ}$ (range $5-10^{\circ}$), HVA $10.5^{\circ}$ (range $2-20^{\circ}$), DMAA $7.2^{\circ}$ (range $0-14^{\circ}$) correctively. Mean operative time was 15.5 minutes (range 11-18 minutes) and mean operative time was 5.6 days (range 2-8 days). Conclusion: Despite small skin incision and short operative time and admission period, linear distal metatarsal osteotomy with minimal skin incision showed similar results with conventional distal metatarsal osteotomy. Thus, it was thought to be useful operation in mild and moderate hallux valgus deformity.

  • Purpose: In general, orientals including Korean, have a mesocephalic face whereas Caucasians, among the western, have a dolichocephalic face. Unlike the western, in orientals including Korean, prominent malar bones are recognized as stubborn and unattractive appearance. That is why reduction malarplasty is one of the most popular aesthetic surgical procedure in Korea. Many surgical methods to reposition prominent malar bones have been performed by means of a coronal incision or a combined incisions, using both the intraoral and the external incision. Bicoronal approach has advantage such as wide operative field, easy to maintain symmetry and possibility of combining facial lift but has shortcoming, such as external scars, long operative time, and the possibility of facial nerve or artery injury. Intraoral approach has advantages of short operative time, simplicity of procedure and no external scar. But this approach is associated with problems of cheek drooping, limited exposure and difficulty in making symmetry. Methods: During 8 years, we performed a reduction malarplasty without internal fixation through an minimal intraoral incision and dissection in 39 patients. Results: The patients were followed for 46 months, with satisfactory results and no cheek drooping. There was no patient who want to revise the inappropriate operative result such as asymmetry and incomplete correction. Conclusion: We conclude that minimal intraoral incision and dissection could acquire satisfactory result of reduction malarplasty along with prevention of cheek drooping.
