  • The mandibular contour determines the shape of the lower part of the face and thus influences the appearance of the face. A patient with a large, squarish, or broad face who desires a small, round, or slender face can undergo mandibular contouring surgery to reduce the width of the lower face. The successful correction of a prominent mandibular angle by conventional angle ostectomy has been reported. But, in the majority of patients with a widened facial appearance, both the mandibular angle and part of the mandibular body anterior to it are protuberant laterally, so both must be resected. The purpose of this study is to introduce a new method of performing mandibular contouring surgery, more effectively and easily, and to reduce postoperative complication and evaluate its results. We treated 6 patients who has prominent mandibular angle using multiple step osteotomy with angle-splitting ostectomy. The advantages of this new method are as following. (1) easily performable (2) effective mandibular contouring surgery by reducing the width of lower face (3) producing a natural relief of the mandibular angle (4) low risk of soft tissue damage and complications (5) shortening of the operation time. etc.

  • Background: Recent trends suggest that minimally invasive cardiac surgery reduces postoperative morbidity and offers a cosmetic benefit. This study was performed to evaluate the CPB time, ACC time, OP time, ICU stay and postoperative hospital stay following a lower partial sternotomy and those of the median sternotomy. Material and Method: A group of 26 adult patients who underwent cardiac surgery through lower partial sternotomy from August 1997 to July 1999(A group) were compared to 45 adult patients who underwent cardiac surgery through median sternotomy from January 1996 to July 1997(B group). The mean ages(46.4$\pm$14.6 years, A group and 46.8$\pm$13.2 years, B group) were similar. Operations were performed with central cannula and antegrade/retrograde blood cardioplegia. Result: There was no death in each group. No differences were found in CPB time, ACC time, OP time, ICU stay and postoperative hospital stay. Postoperative complications were sternal splitting in a patient in group A and a patient with bleeding that required reoperation and a patient with delayed wound closure in group B. Conclusion: The lower partial sternotomy offered a cosmetic benefit, but does not significantly reduced the length of operative time and hospital stay. Minimally invasive cardiac surgery will be applied increasing because of the suggested advantage and choosing a proper operative technique will be helpful.

  • Three-dimensional solid model has not been widely used in surgical prediction of orthognathic surgery because frequent artifacts from occlusal restorations or prosthesis limited the usefulness of simulated surgery involving occlusion. We prepared three-dimensional(3D) solid model from CT data and integrated the 3D solid model with dental cast using a face-bow transfer technique combined with skeletal reference measurement and confirmation with cephalometric radiographs. With this simple and easy method, it was possible to predict bony interference between the proximal and distal segment of the mandible so that we can prevent condylar displacement after sagittal split ramus osteotomy of the mandible with prominent asymmetry. The method error was within 2mm and it seemed to be useful in preoperative planning for maxillofacial surgery with maxillo-mandibular occlusal change.

  • Purpose: Traditional transcutaneous incision and transconjunctival incision methods are commonly used in the lower blepharoplasty. The transconjunctival method leaves no visible scars nor does it change the shape of lower eyelid contour and the surgical technique is not difficult. However removal of excess baggy skin is not possible through this method. Therefore, the transconjunctival incision method is useful only for patients who still have normal elasticity of the lower eyelids and fat that is protruding only anterocaudally. The Author will introduce a technique, which complements the limitations of these two methods mentioned above. Methods: The author combined the transconjunctival approach and lower blepharoplasty with only the excised skin flap method. This method does not go beyond the previous methods but does apply the advantages of them. Results: From March 2007 to October 2010, this new technique was performed in a total of 62 patients. Fat was removed and repositioned through transconjunctival incision. Drooped skin was excised as in the traditional blepharoplasty but only the skin flap was elevated. This prevents post-operative complications such as ectropion, sclera show, and deformation of the shape of the lower eyelids or under-resection of fat. All patients were satisfied with the post-operative appearance. Conclusion: The author was able to get satisfactory results while avoiding complications of traditional transcutaneous technique with this combined technique of the transconjunctival approach and the lower blepharoplasty method of skin flaps only.

  • The septal extension graft is a very useful method of controlling nasal lengthening and tip projection, rotation, and shape by fixing a graft to the septum, which leads to a strong supporting structure. Enhancing graft stability is important for better long-term outcomes and minimizing complications or relapse, and even more efficient application of these methods is needed for East Asians who lack enough cartilage to be harvested in addition to possessing a weak cartilage framework. In this paper, the methods for overcoming the drawbacks of the septal extension graft, such as instability, a fixed tip, and insufficiency of cartilage, are presented, and the applications of each method for greater satisfaction with surgical outcomes are also discussed.

  • Most interdigital neuroma can be diagnosed clinically. But, diagnostic local injection method, sonography and magnetic resonance image(MRI) have been used as secondary tests for clinical confirmation or surgery. Recently, there have been active discussions on the method of interdigital neuroma diagnosis for which sonography or MRI is used. For finding out the location or the number of interdigital neuroma particularly in non-typical clinical manifestation or surgery, MRIs, which are exellent in tissue contrast, may be quite helpful. This case had an interdigital neuroma showing non-typical manifestation. MRIs were used for clinical diagnostic confirmation and finding out the location and the number of interdigital neuroma. Thus, the validity along with literary consideration is being reported.

  • For a bursal-side retracted laminated rotator cuff tear, simple repair of the retracted bursal-side rotator cuff might be insufficient because the repaired tendon could remain as an intratendinous tear of the rotator cuff. We present a repair method for intratendinous rotator cuff tears using the suture-bridge technique. We believe that this method helps to preserve the remnant rotator cuff tendon without tissue damage and restores the normal rotator cuff footprint in bursal-side delaminated rotator cuff tears.

  • 비절개식 봉합법의 하나인 이 술식은 이론적인 배경은 너무나 잘 알려진 술식이나 적용시에 저자가 제안한 예정 중검선의 설정방법은 실제 술중에 간단하면서도 중검선이 개개인의 검판의 모양에 따라 형성되기에 유용한 방법으로 합병증의 가능성이 낮아서 임상에서 유용하게 상용될 수 있다고 생각된다. 결찰시 실을 이용한 봉합 매듭의 고정법, 그리고 발사를 하기 때문에 결찰하여 매몰된 실에 의한 염증을 피할 수 있는 장점은 비절개식 중검술의 적응증인 경우에 유용하게 사용될 수 있다고 사료된다.

  • Purpose: To study inter- and intra-observer reliabilities of computerized measurements of the angular parameters of hallux valgus deformity, using two different kinds of software tools for angle measurement on the digital radiography. Materials and Methods: On 35 digital radiographies of standing foot anteroposterior view of hallux valgus, two observers (A, B) independently measured hallux valgus angle (HVA) and 1-2 intermetatarsal angle ($IMA_{1-2}$) twice, using two methods. In method I, an angle was determined from duplicated lines to longitudinal axes made for bisecting line on the target bones with software tool. In method II, an angle was calculated automatically and directly from bisecting lines (longitudinal axes) made on the target bones. We compared two methods using paired t-test to determine significance of differences. Inter- and intraobserver reliabilities were evaluated using the intraclass correlation coefficients (ICC). Results: There were no significant differences between measurements of method I and II for each observer (p>0.05) and intraobserver reliability were good. (ICC>0.9) Inter-observer reliability for method I and II was good of the HVA (ICCs, 0.912 and 0.905) and moderate of the $IMA_{1-2}$ (ICCs, 0.505 and 0.537). There were interobserver differences in HVA of method I and II. Conclusion: No significant difference was found statistically between measurements of method I and II. Both methods I and II would be acceptable to measure angular parameters of hallux valgus deformity.

  • Purpose: The purpose of this study was to compare the method of using coraco-clavicular (C-C) sling with modified Phemister operation by postoperative clinical results, radiologic analysis and complications. Materials and Methods: 33 patients of acromioclavicular joint dislocation were included in this study. Thirteen patients were treated with simple C-C sling method and twenty patients were treated with modified Phemister operation. The assesment of clinical and radiological evaluation were performed and the final results were examined by using the Weitzman's classification. Results: In the final result of C-C sling method group, forward elevation $161^{\circ}$, external rotation $70^{\circ}$, internal rotation T8 level, Visual Analogue Scale (VAS) 83.3 points were checked. In modified Phemister operation group, forward elevation $155^{\circ}$, external rotation $67^{\circ}$, internal rotation T6 level, VAS 83.8 points were checked. In coracoclavicular distance of C-C sling method group, pre-operation 12.82 mm and last follow up 8.37 mm were checked. In modified Phemister operation group, pre-operation 12.8 mm and last follow up 7.7 mm were checked. In functional evaluation by the Weitzman criteria, C-C sling group had excellent 8, good 1, fair 1 and modified Phemister group had excellent 13, good 4, fair 3. Conclusion: C-C sling method would be the better than the Modified Phemister operation because of short operation time and smaller skin incision.
