The conservative treatment of the condylar fracture has been used for a long time because of its simplicity, good prognosis and less complication. Traditionally the conservative treatment has been carried out by maxillomandibular fixation using arch bar and wire. But a simplified technique of maxillomandibular fixation introduced here is a procedure that 4 bone screws are placed above the apecies of the maxillary and mandibular canines and then ipsilaterally placed maxillary and mandibular bone screws are linked by a loop of wire each other. This procedure has several advantages compared with the traditional maxillomandibular fixation method. 1) it provides simplicity for the operators. 2) it sustains maxillomandibular fixation more rigidly compared with arch bar technique. 3) it keeps stable maxillomandibular fixation in the region of the anterior teeth so that anterior open bite tendency can be remarkably minimized. 4) it does not injure the periodontal tissue because the teeth are not engaged and causes less discomfort to the patient. 5) it decreases the possibility of operator's AIDS infection through inadvertent skin puncture. 6) it is highly recommended for the patients whose teeth are available for maxillomandibular fixation. The two male patients were diagnosed as bilateral condylar and symphyseal fracture of the mandible. They restored stable occlusion and functional mandibular movement only by a simplified technique of maxillomandibular fixation.

In the presence of acute pericoronitis of mandilbular third molar, antibiotic therapy and early incision and drainage are the method of choice, followed by definitive surgical extraction of the tooth as soon as it becomes subacute. If excision of the overlying tissues is decided on, it should be done adequately. All overlying tissues must be throughly excised, and the crown portion of the unerupted tooth should be completely exposed. After excision has been completed, the wound should be managed with a surgical dressing. This should be allowed to remain approximately 7 days. And then, surgical extraction of the impacted mandibular third molar can be done usually. In this operation, there are many complications, such as, postoperative bleeding, infection, trismus, dysphasia and paresthesia. The surgeon are discredited and medicolegal problem may be occurred in the presence of many distressed complications. Therefore, the relatively nonsurgical treatment is the method of choice. So, authors selected the conservative treatment methods of incision and drainage, primary endodontic drainage, operculectomy without surgical extraction of the mandibular third molars. The results were more favorable without the postoperative complication in Wonju old offender prison.

Purpose: Most clavicular fractures can be healed by conservative treatment, although there are many factors that influence healing. The aim of the present study was to analyze factors that influence (i) bone union of midshaft fractures of the clavicle treated conservatively and (ii) bone functioning, after union. The long-term goal was to determine which treatments are adequate. Materials and Methods: We evaluated factors that have an effect on bone union and bone function after union. We evaluated age, fracture site, comminution, displacement, shortening and other factors. Among 523 clavicular midshaft fractures that presented between January 2004 and Jun 2009 at our Department of Orthopaedic Surgery, we identified 270 who had conservative treatment and 173 patients who had surgical treatment. Results: The period required for bone union increased with the degree of displacement. For the group below 12 years of age, and the group without comminution, it took half the time to achieve bone union compared with the other groups. Displacement mostly occurred within 2 weeks after conservative treatment. Conclusion: In patients with a comminuted clavicular midshaft fracture, we might, because of expected delays in bone union, delay the start of rehabilitation until patients are more than 13 years old. Because the degree of displacement may be increased within 2 weeks during conservative treatment, we can think about surgical treatments.

A 21-year-old male visited our emergency room. He could not remember the mechanism of injury. He was found beside a motorcycle. Initial vital sign was stable. Observation and conservative treatment were planned at the intensive care unit (ICU). On the third day at ICU, he complained sudden flank pain. It was colicky and hard to control. Without the pain, he had no specific symptom, sign, or laboratory findings. On computed tomography, renal pelvis was filled with hematoma which induced hydronephrosis. Double-J catheter and percutaneous nephrostomy was implemented by an intervention radiologist. Hematome in the renal pelvis was aspirated during the procedure. Symptom of the patient was subsided after the procedure. He was discharged without specific complications.

Traumatic subcutaneous emphysema, which is the infiltration of air into subcutaneous tissues due to trauma, is caused by various factors such as chest and/or abdominal trauma, facial fractures, and barotrauma caused by mechanical ventilation. In this case report, a 32-year-old woman developed traumatic subcutaneous emphysema after undergoing abdominal liposuction at a local clinic. She was subsequently admitted to Busan Paik Hospital, and with early diagnosis and conservative treatment, she was discharged on the seventh day of hospitalization with no complications. However, because traumatic subcutaneous emphysema may accompany other injuries for various reasons, radiological examination and various tests should be performed to prevent serious complications and sequelae.

A Morel-Lavallée lesion (MLL) is a pathologic fluid collection within an abnormally formed space, resulting from an internal degloving injury between the muscle fascia and subcutaneous fat layer. Due to its resistance to conservative treatments such as drainage or compression dressing, various therapeutic methods have been developed for MLL. However, no standardized guidelines currently exist. Recently, endoscopic debridement and cutaneo-fascial suture (EDCS) has been introduced for the treatment of MLL, particularly for large lesions resistant to conservative approaches. While this procedure is known to be effective, limited reports are available on potential complications. The authors present a case of skin necrosis following EDCS for a massive MLL.

Apical sealing with proper retrograde filling material and technique is the key factor for successful apical surgery. In order to provide impeccable apical sealing and healing, various mechanical and chemical characteristics of retrograde filling material is required. MTA has been used as the gold standard of retrograde filling due to its unprecedented advantages. As MTA has long setting time and difficult handling properties, premixed putty type bioceramic material has been newly developed. For efficient retrofilling with premixed putty type biocreamic material, 'Lid technique' was also proposed. The following cases present apical surgery using newly developed premixed putty type bioceramic material with Lid technique.

One hundred and forty-eight cases of tennis elbow were treated by conservative managements firstly such as rest, medication, immobilization, physical therapy and local steroid injection, from Jan. 1985 to Jun. 1994 at Department of Orthopaedic Surgery, National Medical Center. Among the 148 cases, 16 cases who failed conservative managements, were treated with Nirschl & Pettrone operation. The results were summarized as follows, 1. Among the 148 cases, 110 cases$(74\%)$ were female, and 61 cases$(41.2\%)$ were in the age group 41 to 50, and mean age was 42.3 2. Ninety-nine cases were housewives and only 15 cases were related to sports. 3. The results 116cases$(78\%)$, of conservative treatment were excellent and good 10 fair and failure in 32 cases$(22\%)$, by Nirschl and Peettrone assessment. 4. Among the 16 cases who were treated with Nirschl and Pettrone operation, excellent result was obtained 10 7cases, good in 3 cases, fair in 4cases and failure in 2 cases. 5. Recurrence was developed in 18 cases$(12.2\%)$, and we obtained excellent & good result in 17 cases with both conservative and operative treatment. Above results suggest that the term, tennis elbow is a misnomer because it occurs more commonly in non-athletes such as housewives than in tennis players. So it seems to be a occupational disease rather than sports injury. Now, we propose eliminate of the term, elbow and substitute with terminology that described the true understanding and therapeutic orientation of it.

A total of 44 patients with extremity soft tissue sarcomas had received conservative surgery and radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine between Jan. 1980 and Dec. 1990. Initial surgical treatment consisted of intracapsular excision in 33 patients $(75\%),$ marginal excision in 9 patients, and wide excision in two patients. Total radiation doses were between 40Gy and 65Gy (median 60 Gy). Median follow-up period was 47 months. Overall actuarial 5-year survival rate was $76.9\%$ and 5-year recurrence free survival rate was $39.3\%.$ There was no statistically significant prognostic factors but the 5-year survival rates tended to be decreased in the patients with high grade tumors and treated with narrow surgical extent. Sixteen patients recurred during fellow-up (16/31, $51.6\%).$ The incidence of initial local recurrence was $22.6\%$ (7/31) and distant metastasis was $29\%(9/31).$ Of the 7 who did not have metastasis at diagnosis of local recurrence, 5 were submitted to a salvage treatment. All of them achieved local control and distant metastasis appeared in three of them. In conclusion, conservative surgery and radiation therapy in the patients with extremity soft tissue sarcomas was the effective treatment modality.

Objectives: Infererior alveolar nerve (IAN) damage may be one of the distressing complications occurring during implant placement. Because of nature of closed injury, a large proportion is approached non-invasively. The purpose of this study was to analyze the outcomes of conservative management of the injured nerve during dental implant procedure. Materials and Methods: Sixty-four patients of implant related IAN injury, who were managed by medication or observation from January 1997 to March 2007 at the Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital, were retrospectively investigated. The objective tests and subjective evaluations were performed to evaluate the degree of damage and duration of sensory disturbance recovery. Tests were performed on the day of the first visit and every two months afterward. Patient's initial symptoms, proximity of the implant to the IAN, time interval between implant surgery and the first visit to our clinic, and treatment after implant surgery were analyzed to determine whether these factors affected the final outcomes. Results: Among the 64 patients, 23 had a chief complaint of sensory disturbance and others with dysesthesia. The mean time until first visit to our hospital after the injury was 10.9 months.One year after nerve injury, the sensation was improved in 9 patients, whereas not improved in 38 patients, even 4 patients experienced deterioration. Better prognosis was observed in the group of patients with early visits and with implants placed or managed not too close to the IAN. Conclusion: Nearly 70% of patients with IAN injury during implant placement showed no improvement in sensation or dysesthesia with the conservative management. Earlier decision for active treatment needs to be considered because of possibility of deterioration of symptoms and unsatisfactory recovery.
