Several reports have described the increased perioperative risks as well as surgical techniques for performing various procedures in obese patients. However, few reports have addressed the effects of obesity on routine arthroscopic procedures known to be common and safe. Describing the case of a partial meniscectomy performed in a 17-year-old male with a body weight of 120 kg, we review literatures published to the present and provide technical problems and possible complications that can occur when performing routine knee arthroscopy in bariatric patients.

If complication arises after glossectomy which leads to trouble in forming food bolus or transfer of the food, it is possible that either food bolus may block the airway or dysphagia may occur as the food bolus goes down into the airway. To solve the issue, palatal augmentation prosthesis could be used. In this case, the patient with an oral cancer is having difficulties swallowing food after glossectomy. Through taking impressions of polishing surface of his denture referring his tongue movement, the complete denture for the upper jaw was created using the concept of palatal augmentation prosthesis. This new upper denture increases the palatal-tongue contact pressure, allowing the patient to perform better swallowing and better pronunciation.

Purpose : To analyze the clinical results of isolated lateral meniscus injury according to discoid versus non-discoid, athletes versus non-athletes and repaired cases versus cases treated with meniscectomy. Materials and Methods : Between January 1997 and June 2000, arthroscopic lateral meniscus surgery was performed in 329 cases. We reviewed 80 cases of isolated lateral meniscus injury without associated ligament injury or other pathologic condition retrospectively. The study population was composed of 54 males and 26 females with average age of 30.2 years(range, $17\~40$ years). Average follow up period was 15 months(range, $12\~39$ months). Eighty cases were classified into three categories; discoid group versus non-discoid group, athletes versus non-athletes, repaired cases versus cases treated with meniscectomy. Clinical evaluation was performed using Lysholm knee score and Tegner activity. Results : Non-discoid group had higher incidence of longitudinal tear than discoid group. Athletes group had higher incidence of repaired cases than non-athletes group. The repaired group had better clinical result than patient treated with meniscectomy group. Conclusion : Although lateral meniscus has some special features including anatomic mobility which can cause instability after meniscectomy and technical difficulties in repairing, it is recommended repairing meniscus tear not only longitudinal but also horizontal and complex tear to obtain better clinical results.

Purpose: To study the long-term outcome of arthroscopic meniscectomy with regard to clinical symptoms and radiographic signs of osteoarthritic change. Materials and Methods: The materials for the investigation consisted of 79 individuals among 144 patients who underwent knee arthroscopy due to an isolated meniscal tear from October 1990 to September 1992 in our hospital. Those 79 individuals were followed up for $10{\sim}15$ years after the knee arthroscopy and were took clinical examination through the review of knee radiographies obtained with weight bearing. 52 of the 79 patients were men, and the mean age of the total materials was 34.6 years old (in the range $17{\sim}48$). Results: At follow-up, radiographic changes including Fairbank changes and joint space narrowing were seen from 45 of the 79 patients (56.2%). In other calculation, radiographic changes were seen in 23 out of 54 patients (42.6%) who had a partial meniscectomy, but were presented in 22 out of 25 patients (88.0%) who had a total meniscectomy. As a result, more radiographic changes were seen after total meniscectomy (p=0.03). In clinical results, 39 out of 54 patients (72.2%) after partial meniscectomy were satisfactory, and 14 out of 25 patients (56.0%) after total meniscectomy were satisfactory, therefore, more percentage of patients were satisfactory in partial meniscectomy group than in total meniscectomy group, but the statistical differences were absent (p=0.24). Conclusion: The frequency of radiographic changes in $10{\sim}15$ years after meniscectomy was related to the quantity of the meniscus removed, but the differences of these changes were low and had little influence on activity and knee function.

Congenital or traumatic loss on the oral and maxillary area or the loss of jaws due to the surgical excision of a tumor causes functional problems, such as masticatory and swallowing disorders, phonetic problems and psychological disorders in patients. In most cases, a prosthetic restoration is needed to resolve these problems and restore the damaged tissue and function. When loss occurs on the maxilla, foods and liquids leak into the nasal cavity, and a nasal sound can be heard due to air leakage into the removed area. In these cases, the palatal obturator can be used to improve the esthetic and functional aspects because it restores the removed area of the maxilla and closes the opened route between the oral cavity and maxillary sinus or nasal cavity. In this case report, a palatal obturator was applied to patients who had a hemimaxillectomy due to the occurrence of squamous cell carcinoma on the right maxillary area. Therefore, fundamental functions, such as phonetic and swallowing functions were restored, and the esthetic aspects of the facial profile were improved.

Heart transplantation was planned for a 10-year old boy who had dilated cardiomyopathy with severe congestive heart failure and had been on dopamine for 1month. However, partial left ventriculectomy and mitral annuloplasty were performed instead, because there was no donor heart of the adequate size and the symptoms were aggravated. The clinical symptoms were markedly improved after the surgery. Comparing the postoperative echocardiographic results with the preoperative results, there were remarkable changes in the left ventricular ejection fraction(preoperative LV EF 17% to postoperative 3 months 29%, 6 months 35%, 1 year 36%) and the left ventricular end-diastolic dimension(preoperative 72 mm to postoperative 3 months 59 mm, 6 months 61 mm, 1 year 61 mm). Partial left ventriculectomy and mitral annuloplasty reduced the cardiac loading in the dilated cardiomyopathy. Partial left ventriculectomy and mitral annuloplasty may be considered as one of the alternative surgical metho s to carry over until a heart transplantation can be performed, especially for children.

The cause and clinical course of the postoperative ARDS is, as of yet, not very well understood. The current study is a review of our experience on patients with ARDS after thoracotomy. Material and Method: Between Jan. 1996 to Aug. 2001, a retrospective analysis was conducted on 32 post-thoracotomy ARDS patients among 4018 patients receiving thoracotomy inclusive of thoracoscopic surgery. Result: The incidence of ARDS after pneumonectomy cases was 5.3%(13/245), 1.3% after lobectomy(9/ 710), and 4.4% after esophageal surgery(10/226). Of the 32 ARDS patients, 31 had malignant disease. The remaining 1 patient had aspergillosis. In the majority, the cause of ARDS was unknown. The average onset was on the 7.4th postoperative day. In 10 cases, the initial lesion was in the right lower lung field(31.2%), in the left lower lung field in 9(28.1%), and in both lower lung fields in 12(37.5%) cases. In all, the initial lesion was in the lower lung fields in 96.9% of the cases(31/32). There was a significant relationship between the development of ARDS and intraoperative I/O balance. The overall mortality rate was 65.6%(21/32). In the earlier period of the study(1996-Jun, 1998) the mortality rate was 100%, but in the latter period(July, 1998-Aug, 2001) it was significantly reduced to 47.6%: Conclusion: The current data showed a higher incidence of postoperative ARDS in patients with malignant disease and in those receiving extensive lymph node dissection with either lobectomy or pneumonectomy, and also in patients receiving esophageal surgery. In addition, introperative fluid overload was also associated with an increased incidence of ARDS. Treatment outcome could be improved with prone positioning and NO gas inhalation.

The tongue is one of the most common sites of oral cancer. Glossectomy is known as the gold standard for tongue cancer treatment. However, surgical removal can lead to reduced mobility of the tongue and the patients may have difficulty performing normal oral functions like swallowing and pronunciation. Therefore, additional prosthetic consideration to supplement the function of the impaired tongue is needed for oral rehabilitation of such patients. Palatal augmentation prosthesis helps the tongue to reach the palate by lowering the position of the palatal polished surface. The oral functions of the patients with limited tongue mobility can be improved by the prosthesis. In this case, palatal augmented maxillary denture and conventional mandibular denture were fabricated for the completely edentulous patient with reduced tongue mobility after glossectomy due to tongue cancer. As a result, the oral functions of the patient were improved with the prosthesis.

Epithelioid hemangioendothelioma (HE) is a very rare malignant tumor that is pathologically benign tumor originating from endothelial cell but clinically presents metastasis and recurrence. A 29-year-old asymptomatic man, preoperatively diagnosed as lung cancer in the left lower lung, underwent a lobectomy, a wedge lung resection of left upper lung, and partial resection of diaphragm. Left lower lobar lesion was confirmed as pulmonary epithelioid hemangioendothelioma, but the lesions of the left upper lung and diaphragm were remained calcified by spontaneous regression of HE. We report a case of subcutaneous metastasis that occurred two times at 10 months and 19 months after previous surgical treatment of pulmonary EH.
