Background : Important factors to determine treatment method and prognosis of oral cancer are anatomical site, tumor size, metastatic lesion, histologic cell differenciation and microvascular invasion. Anatomical site has great effect to oral cancer patient's survival rate because each site's accessibility and lymph node metastasis is different but this factor was't studied much than other factors. Patients and Methods : 228 patients with squamous cell carcinoma of common primary sites(Mandible, Maxilla, Floor of Mouth and Tongue) in oral cavity who were diagnosed in the Korea Cancer Center Hospital from January 1989 to December 1999, were clinically studied and analyzed on survival rate. Results : 1. Survival rates of each anatomical sites were Tongue(36.8%), Mandible(33.3%), Maxilla(28.7%) and Floor of Mouth(24.5%). Survival rates difference between Tongue and Floor of Mouth has significance(p<0.05). 2. Survival rates for early cancer of each site were Maxilla(100%), Mandible(57.1%), Tongue(54.2%) and Floor of Mouth(46.7%). Survival rates difference between Maxilla and Floor of Mouth has significance(p<0.05). 3. Survival rates by surgery method of each site were Maxilla(60.6%), Tongue(56.9%), Mandible(44.8%) and Floor of Mouth(26.3%). Survival rates difference between Maxilla and Floor of Mouth has significance(p<0.05). 4. Survival rates by radiation or chemo method of each site were Floor of Mouth(23.5%), Mandible(20.0%), Maxilla(9.5%), and Tongue(9.1%). Survival rates difference between each site doesn't have significance(p>0.05). 5. In advance stage, Survival rates by single therapy of each site were Tongue(33.6%), Mandible(23.5%), Floor of Mouth(16.7%), Maxilla(0%), and Survival rates difference between Maxilla and Tongue has significance (p<0.05). Survival rates by combination therapy of each site were Mandible(38.1%), Maxilla(30.0%), Floor of mouth(18.2%), Tongue(12.5%), and Survival rates difference between Mandible and Tongue has significance(p<0.05). Conclusion : Survival rate of tongue is higher than the other sites, early detection of oral cancer can increase survival rate at any site and combination therapy is the most effetive method, especially at maxilla.

Background The most common cutaneous malignant masses are basal cell carcinoma (BCC) and squamous cell carcinoma. The predominant site of a malignant mass is the face, which has many opportunities to be exposed to ultraviolet radiation. However the predilection sites of malignant masses have been equivocal due to the use of general regions, rather than anatomical landmarks, in surveys. A facial esthetic unit is an anatomical site classified as an area of similar facial contour characteristics that can be distinguished from other areas. The purpose of this study is to determine widely accepted anatomical landmarks using the esthetic unit. Methods We retrospectively analyzed 118 cases of malignant masses in our clinic from January 2005 to October 2012. We evaluated the patients' age, gender, and predilection site of the malignant mass by esthetic unit through pathology, medical records and patient photographs. We mapped the occurrence site of the malignant mass on schematic drawings of the esthetic units. Results Most of the malignant masses were BCC. The ratio of males to females was 1:1.41. The frequent predilection site of a malignant mass was on the nasal unit (33.1%), followed by the buccal unit (11.0%). Primary closure was the most common method of repairing a surgical defect (38.9%), followed by a local flap (35.5%). Conclusions This review described the relationship between clinical characteristics and esthetic units by proposing objective predilection sites for malignant masses, which can be used commonly as a framework in the study of malignant masses by unifying equivocal occurrence sites.

The skin is one of the largest organs in our body and participates in many of the human organism's physiological and pathological events. Skin function were known for self-maintenance and self-repair, mechanical and chemical stress protection, protection against UV and environmental pathogenic micro-organisms, production of vitamin D, and social and psychological function through the physical aspect. The aim of this study was to evaluate the variation of biophysical parameters and to find relation with skin biomarkers in different anatomical site and age in Korean women. About 70 healthy volunteers in age range 20 to 49 were participated in this test. Test areas were the forearms and the cheek. Investigation to determine biophysical parameters on human skin, was carried out using various non-invasive methods. For analysis to skin biomarkers, we studied to examine various biomarkers for the quantitative determination of cortisol, fibronectin, keratin-1, 10, and 11, involucrin, and keratin-6 in human face and forearm. And we measured to skin biophysical parameters for skin anatomical site and age difference with non-invasive methods. As results of measuring site, some parameters were have following significant difference, stratum corneum hydration, trans epidermal water loss and skin color (L and a value). As results of age difference, skin colors were had only significant difference with age. For cortisol, keratin-6, fibronectin, keratin-1, 10, 11 contents, there were no significant difference in age and site. However, involucrin level in the cheeks were the highest for age group 30 ~ 39 compared to other age groups. These results suggest that in individual skin condition may explain detailed skin state variation.

Purpose: The purposes of the present study were to find the ideal insertion position syndesmosis screw and relation to the surrounding anatomical structures when indirectly inserting the screw anteriorly at a 30 angle at 3 cm proximal portion of the ankle join t. Materials and Methods: We performed computed tomography from the axial view in 20 normal individuals at 3 cm proximal portion of the ankle joint and divided the lateral side of the fibula into 4 sections. We drew a line from the middle of each of these 4 sections to the posterolateral tibia at a 30 angle and determined the relationship between each of these lines and the surrounding anatomical structures and confirmed the site at which each of these 4 lines passed through the posterolateral tibia which divided into 3 sections and the site of the fibula at which each of these lines passed through the middle 1/3 portion of the tibia. Results: The posterior 3/4 portion of the fibula that passed through the middle 1/3 portion of the posterolateral tibia in 18 cases. The portion did not approach the surrounding anatomical structures(Peroneal vessels and the muscular portion of FHL). Conclusion: The ideal insertion position of syndesmosis screw at 3 cm proximal portion of the ankle joint at a 30 angle is the posterior 3/4 portion of the lateral side of the fibula, and injury to the surrounding anatomical structures could be avoided when the screw passes through the middle 1/3 portion of the posterolateral tibia.

Despite improvements in the surgical treatment of gastric adenocarcinomas, the recurrence rates remain high in patients with advanced-stage disease. Most of the recurrence occurs within 3 years of the surgical resection, and nearly $90\%$ of the patients with recurrence die within 2 years of the diagnosis of recurrence. A recent study analyzed recurrence patterns for patients who had undergone a potentially curative gastrectomy. For those patients, $33\%$ of the recurrences involved locoregional sites, $44\%$ the peritoneum, and $38\%$ distant sites. A 51-year-old female patient was diagnosed with stomach cancer and underwent a total gastrectomy with D2 lymph node dissection during Oct. 1999. The pathologic report indicated a T3N1M0 tumor. We performed immunochemotherapy for 2 years with regular follow up. A gastrofiberscopic examination done during sep. 2004, cancer recurrence was found at the Kim's tie site of the jejunual loop. We did an abdominal exploration and a segmental resection of cancer site with pathologically negative resection margins. After the operation, we started secondary chemotherapy with TS-1.

Purpose: Pain perception is affected by a wide range of contributing factors, including biological, psychological, and social factors. Although the provision of visual information could have a modulatory effect on pain perception, it is unclear whether such a visual effect might vary depending on the anatomical site and stimulation type. This study aimed to analyze the modulatory effect of visual information on the perception of sharp and dull pain in the face and hand and to assess the influence of individual fear levels on modulatory visual information. Methods: A total of 68 healthy male and female volunteers were recruited for this study. Pressure and pricking pain with and without visual information were induced on the masseter and thenar muscles, and alterations in pain threshold were evaluated. The survey was conducted using the Geop-Pain Questionnaire (GPQ). Results: The pricking pain threshold of the hand was significantly elevated when viewing the stimulated hand. This result indicated that the provision of visual information could decrease sensitivity to sharp pain in the hand. However, when correlating the GPQ score with the alteration in thresholds induced by visual information, no significant correlation was observed between the GPQ score and the threshold difference induced by visual information. This finding showed that the visual effect was not significantly affected by the fear level. Conclusions: This study showed that the effect of visual information on the pain threshold could vary according to the anatomical site and stimulation type. A better understanding of such a modulatory effect on pain perception might be useful for clinicians during painful therapeutic procedures.

Reconstruction following a resection of malignant oral cavity tumors is one of the most difficult problems in recent oral oncology. The radial forearm free flap (RFFF) is a thin, pliable soft tissue flap with large-caliber vessels for microvascular anastomosis. Its additional advantages include consistent flap vascular anatomy, acceptable donor site morbidity and the ability to perform simultaneous flap harvest with a tumor resection. For a better understanding of RFFF as a routine reconstructive procedure in oral and maxillofacial surgery, the constant anatomical findings must be learned and memorized by young doctors during the special curriculum periods for the Korean national board of oral and maxillofacial surgery. This review article discusses the anatomical basis of RFFF in the Korean language.

Obstructive Sleep Apnea Syndrome(OSAS), that is a complex disease of neuromuscular, respiratory and cardiovascular system, can be cured by various treatment such as weight control, medical and surgical intervention. As most of OSAS may be caused by various anatomical abnormalities, preoperative evaluation for exact anatomical site of obstruction must be needed. And various diagnostic procedures such as fiberoptic nasopharyngoscopy, Mueller test, cinefluoroscopy, cephalometry, computerized tomography, polysomnography would be used for this purpose. Uvulopalotopharyngplasty is currently the most popular method for the patient with OSAS among various surgical maneuvers and is very effective for the relieving the symptoms as like snoring, daytime somnolence, and nocturnal restlessness etc. Although subjective improvement is not compatible with it's objective assessment in postoperative evaluation for it's results, uvulopalatopharyngoplasty could be a recommandable surgical procedure because of it's ample effectiveness in promoting symptom improvement without any risk of serious complications.

Ependymomas arise from ependymal cells and can grow at any site in the central nervous system (CNS), as well as in some locations outside of the CNS. The latter is rare, contributing to the frequent misdiagnoses of such cases. Herein, we present the case of a 54-year-old man with a history of lower limb weakness and numbness. Magnetic resonance imaging revealed an extradural, heterogeneously enhanced solid lesion with a regular and well-defined border in the posterior mediastinum. A post-resection histopathological examination revealed tumor-forming perivascular pseudo-rosettes that showed immunoreactivity against glial fibrillary acidic protein, epithelial membrane antigen, and vimentin, as well as a high Ki-67 labeling index. Based on pathological features, a diagnosis of anaplastic ependymoma was established.

To clarify the clinical utility of the calvarial bone graft in the maxillofacial reconstruction, we performed on anatomical study by measuring the regional thickness of the parietal bone on 17 Korean adult dry skulls. Before the sectioning the calvarium, the anatomical landmarks were marked on each specimens. And then we measured the total thickness of the parietal bone, the thickness of the outer and inner cortical plates on various points in each sections of parietal bones using a digital caliper under the stereomicroscope. The total thickness of the parietal bone was ranged from 5.17mm to 7.50mm, and there were no statistical difference in the total thickness of the parietal bone on the same points bilaterally. But there was a tendency that the thickness of the parietal bone was thicker toward to the lambda point than the coronal suture area. At the other hand, the thickness of the outer and inner plate of the parietal bone was the thickest at the first point of the right aspect on the line 1, the first point of the left aspect on the line 5, respectively. In conclusion, this study showed that the donor site of the parietal bone for the maxillofacial reconstruction should be located at more posterior and medial area of the parietal bone than the prevalent known donor site.
