The distal thigh atrophy is a frequently associated sigh in the presence of knee pathology, and it is usually proved by the difference of the distal thigh circumference using tapeline measurement. But the proper position of measurement is known at this moment. From January of 1988 to December of 1991, we have 320 patients who had knee problems. Among them, 50 patients were selected as a sample of this study. We measured distal thigh circumference of normal and abnormal side by patella and also real circumference and area by taking cross sectional C-T image at each point of measurement. The obtained data are analysed by SPSS for statistical treatment. And the results are as follows: 1) We notice the largest difference on the point of 10cm above superior pole of patella. 2) The vastus medialis is the most conspicuously atrophied muscle among quadriceps and the atrophy of hamstring is minimal. 3) We have experienced the largest difference in cruciate ligament injury but a little difference in meniscus pathology. 4) There is no significantly difference between tapeline measurement and real circumference. As a conclusion of study, The position of 10cm above from the patella upper pole is the best site of clinical measurement of distal thigh circumference, and the muscle mainly associated with artophy is vastus medialis.

BACKGROUND AND OBJECTIVES: Microsurgical resection of intracordal cysts is technically difficult and challenging because the wall of cysts may be tightly attached to underlying vocal ligament and/or overlying epithelium, and therefore their thin wall will easily rupture during surgical dissection. We aimed to evaluate the voice outcomes of standard microflap subepithelial resection and the recurrence rate depending on the intraoperative rupturing of the cyst. MATERIALS AND METHODS: Medical records of Samsung Medical Center, Seoul, Korea, were reviewed for sixty-four consecutive patients who received surgical resection of vocal cyst using microflap subepithelial dissection technique between the year 2004 and 2013. Meticulous dissection was performed to completely remove the cyst wall while preserving the mucosa and the lamina propria as much as possible. Voice outcomes and recurrence rates were compared according to the type, size and the intraoperative rupture of cyst. RESULTS: Presence or absence of cyst rupture was clearly described in the operation records of 41 patients. Intraoperative rupture of the cyst occurred in 32 of 41 (78%) patients. The recurrence was detected in 5 of 64 (7.8%) total cases and 4 of 32 (12.5%) cases of ruptured cyst, but not in 9 cases of intact extirpation. Rupture was more common in case of mucous retention cyst compared with epidermoid cyst (p=0.036). Subjective and objective voice parameters were measured at before and 3 months after surgery, which improved regardless of the cyst rupture. CONCLUSION: Although complete microsurgical extirpation of intracordal cyst while keeping the cyst wall intact is technically difficult, meticulous dissection with maximal preservation of surrounding tissue may warrant the improvement of voice outcomes.

BACKGROUND AND OBJECTIVES: We evaluated the two-year clinical outcomes in patients with angiographically intermediate lesions according to the plaque burden and treatment strategy. SUBJECTS AND METHODS: We prospectively enrolled patients with angiographically intermediate lesions (diameter stenosis 30-70%) with an intravascular ultrasound (IVUS) minimum lumen area (MLA) <4 mm2 with 50-70% plaque burden of 16 Korean percutaneous coronary intervention centers. Patients were divided into medical therapy group (n=85) and zotarolimus-eluting stent group (ZES; Resolute) group (n=74). We evaluated the incidences of two-year major adverse cardiovascular events (MACE). RESULTS: A two-year clinical follow-up was completed in 143 patients and MACE occurred in 12 patients. There were no significant differences in the incidences of death (1.3% vs. 3.0%, p=0.471), target vessel-related non-fatal myocardial infarction (0.0% vs. 0.0%, p=1.000) and target vessel revascularizations (7.8% vs. 4.5%, p=0.425) between medical and ZES groups. Independent predictors of two-year MACE included acute myocardial infarction {odds ratio (OR)=2.87; 95% confidence interval (CI) 1.43-6.12, p=0.014}, diabetes mellitus (OR=2.46; 95% CI 1.24-5.56, p=0.028) and non-statin therapy (OR=2.32; 95% CI 1.18-5.24, p=0.034). CONCLUSION: Medical therapy shows comparable results with ZES, and myocardial infarction, diabetes mellitus and non-statin therapy were associated with the occurrence of two-year MACE in patients with intermediate lesion with IVUS MLA <4 mm2 with 50-70% of plaque burden.

Background/Aims: The study investigated the incidence of thromboembolic events (TEE) in head and neck (H&N) cancer patients who received concurrent chemoradiotherapy (CCRT) with cisplatin, and analyzed the factors affecting TEE occurrence Methods: Two hundred and fifty-seven patients who started CCRT with cisplatin for H&N cancer from January 2005 to December 2019 were analyzed. Results: TEE occurred in five patients, an incidence rate of 1.9%. The 2-, 4-, and 6-month cumulative incidences of TEE were 0.8%, 1.6%, and 1.9%, respectively. Khorana score was the only factor associated with TEE occurrence (p = 0.010). Conclusions The incidence of TEE in H&N cancer patients who underwent CCRT with cisplatin was relatively low when compared to other types of cancer. However, patients with a high Khorana score require more careful surveillance for possible TEE occurrence.

PURPOSE: This study sought to determine the 1-year clinical effectiveness and safety of a biodegradable, polymer-containing Biolimus A9™-eluting stent (BES) in Korean patients with acute coronary syndrome (ACS). MATERIALS AND METHODS: A total of 1000 ACS patients with 1251 lesions who underwent implantation of BESs at 22 centers in Korea were enrolled between May 2011 and July 2013. We assessed major adverse cardiac events (MACE) defined as the composite of cardiac death, non-fatal myocardial infarction (MI), and clinical-driven target vessel revascularization at 12 months. RESULTS: Patient mean age was 62.6±11.4 years. 72.8% of the patients were male, 28.5% had diabetes, 32.8% had multi-vessel disease (MVD), and 47.9% presented with acute MI (AMI). The mean global registry of acute coronary events risk score of all patients was 103.0±27.6. The number of stents per patient was 1.3±0.6. The incidences of MACE and definite stent thrombosis at 12 months were 3.9% and 0.2%, respectively. On multivariate Cox-regression analysis, age ≥65 years was identified as an independent predictors of 1-year MACE (hazard ratio=2.474; 95% confidence interval=1.202−5.091). Subgroup analyses revealed no significant differences in the incidence of MACE between patients with and without diabetes (4.3% vs. 3.7%, p=0.667), between those who presented with and without AMI (4.4% vs. 3.4%, p=0.403), and between those with and without MVD (4.6% vs. 3.5%, p=0.387). CONCLUSION: Our study demonstrated excellent 1-year clinical outcomes of BES implantation in patients at low-risk for ACS.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.
