Trismus is a common problem to most people experiencing at once in his or her life and to most dental practitioners experiencing frequently. It has a number of potential causes which are single factor or complex factors. Its treatment will depend on the cause. The purpose of this study was to discuss the causes of trismus condition and the various treatments available. This study was made by reviewing of collected data from 86 patients complained of trismus among patients who were diagnosed by TMD, tumor, infection including tetanus, soft tissue anomalies, bony fracture and ankylosis from Jan 2002 to Dec 2004 on department of oral and maxillofacial surgery at Pusan National University Hospital, South Korea. The clinical reviews regarding chief complaints, clinical characteristics, diagnostic examination, treatments and the results on the patients were given as follows. 1. The etiology of trismus commonly were derived from temporomandibular joint(TMJ) disorder, TMJ ankylosis, TMJ tumor, odontogenic maxillofacial infection, mandibular condylar fracture, tetanus. 2. The chief complaints of trismus patients were progressive mouth opening limitation, TMJ pain, malocclusion, facial asymmetry, retrognathic state. 3. Especially, for the differential diagnosis between the fibrous ankylosis and true bony ankylosis, computed tomogram (CT) was useful. Surgical gap arthroplasty on bony ankylosis patients was applied and the gain of mouth opening after operation was average 35.8 mm during 19 months. 4. The tetanus, rarely, also induced the trismus with the range of mouth opening less than 10 mm. The average serum level of tetanus anti-toxin was 0.02-0.04 IU/mL. The limitation of mouth opening was improved into average 38 mm on 4 weeks after injection of 10,000 units of tetanus immune globulin. 5. In the treatment of osteochondroma, TMD, odontogenic infection and fracture, and the others inducing trismus, to obtian the maximum result and decreased inadequate time and effort, it is important to finding the causes from the exact clinical examination and diagnosis.

It is difficult to manage the growing deformity of forearm bone caused by hereditary osteochondromatosis in children, because deformity and discrepancy of limb length is progressive. The are many treatment methods of these problems including excisio of osteochondroma, lengthening of ulna, shortening of radius, corrective osteotomy with or without lengthening apparatus. Among many treatment methods, we tried free vascularized epiphyseal transplantation with the proximal fibular epiphysis in 3 patients of hereditary osteochondromatosis for inducement of continuous bone growth and deformity correction. The average duration of follow up was 7 years and 1 month, the shortest duration being to 4 years and 5 months and the longest 10 years and 8 months. Serial radiologic and clinical evaluation were carried out during follow up and there were satisfactory length gain, deformity correction and improvement of adjacent joint motion in 2 cases. According to our follow up evaluation, free vascularized epiphyseal transplantation is valuable procedure in forearm deformity of hereditary osteochondromatosis although it needs skillful and experienced operative technique.

A parosteal lipoma is a benign tumor containing mature adipose tissue and is intimately related to the adjacent periosteum. We experienced a very rare case of parosteal lipoma arising from the shaft of femur. A 46 years old lady visited the hospital with complaining of slowly growing mass in her thigh for 7 month. Initially, it was difficult to differentiate from osteochondroma, parosteal osteosarcoma or liposarcoma. Based on the assessment of plain radiogram and magnetic resonance imaging, it was suspected the parosteal lipoma or osteosarcoma. Marginal excision was performed, and it was confirmed to parosteal lipoma histologically. We present the case with review of literatures.

The incidence of chest wall tumor is rare than those of other portions of the body. The chest wall tumors need special attention about their diagnosis and management than other tumors. From March, 1985 to September, 1994, 33 patients with chest wall tumor underwent surgical treatment, and those were consisted of 28 benign tumors and 5 malignant tumors arising from soft tissue, rib and sternum.Benign tumors were included 11 lipoma, 4 cysticercosis, 2 chondroma and 1 each of fibroma, dermatofibroma, osteochondroma, fibrous dysplasia and hemangioma,and 6 other cases. Malignant chest wall tumors were included 2 metastatic carcinoma,1 each of giant cell tumor, chondrosarcoma and epithelioid sarcoma.Sex ratio of male to female was 1.5:1, and the range of age was 16 to 72 years,and the mean age was about 40 years. Clinical manifestations of chest wall tumor were palpable mass[55% , pain[21% ,tender mass[9% , growing mass[9% and asymptomatic[9% .The all cases were treated surgically, the results were as follows:Local excision 16 cases, wide resection 12 cases, wide resection with chemotherapy 3 cases, each one case of wide resection with radiotherapy and wide resection with chest wall reconstruction.

안모비대칭은 심미적 정서적으로 영향을 줄 뿐만 아니라 기능적인 장애를 초래하는 경우도 있다. 안모비대칭은 안면골 중에서 특히 하악골과 관련된 경우가 많은데 이는 하악골이 안면하부의 연조직을 지지하므로 작은 위치, 형태 변화에도 두드러지게 나타나기 때문이다. 비대칭안모를 초래하는 하악과두의 거대증은 Hyperplasia, Hypertrophy, 골증, 외골증, 골연골증, 연골육종 등을 들 수 있다. 비대칭안모 분류는 여러 학자에 의해 다양하게 분류되지만 Bruce와 Hayward는 Deviation prognathism, Unilateral macroganthia, Unilateral condylar hyperpiasia로 분류한 바 있다. 과증식된 하악과두의 절제술은 1856년 Humphry에 의해 최초로 시행된 후 여러 학자들에 의해 성공적으로 시행되고 있다. 본 증례에서는 Unilateral condylar hyperlpasia와 골연골종으로 인한 안모비대칭 환자로써 Condylectomy, Le Fort I osteotomy, Vertical ramus osteotomy, Mandibular inferior border ostectomy, Genioplasty 등을 시행하여 심미적 기능적으로 양호한 결과를 얻었기에 이를 보고하는 바이다.

Thromboembolic complications (TECs) are clinically important sequelae of nephrotic syndrome (NS). The incidence of TECs in children is approximately 2%-5%. The veins are the most commonly affected sites, particularly the deep veins in the legs, the inferior vena cava, the superior vena cava, and the renal veins. Arterial thrombosis, which is less common, typically occurs in the cerebral, pulmonary, and femoral arteries, and is associated with the use of steroids and diuretics. Popliteal artery thrombosis in children has been described in cases of traumatic dissection, osteochondroma, Mycoplasma pneumoniae infection, and fibromuscular dysplasia. We report of a 33-month-old girl with bilateral iliac and popliteal arterial thrombosis associated with steroid-resistant NS due to focal segmental glomerulosclerosis. Her treatment involved thrombectomy and intravenous heparinization, followed by oral warfarin for 8 months. Herein, we report a rare case of spontaneous iliac and popliteal arterial thrombosis in a young child with NS.

Purpose: The earlobe is one of the areas which are most vulnerable to trauma. Various auricular diseases need compression treatment. We report a new compression method using magnetic disks. Methods: Seventeen patients with auricular diseases were treated from October 2002 to September 2006. The mean age was 29.1 years. The diseases details were osteochondroma in 2 patients; cauliflower's ears in 2 patients; acute otohematoma in 1 patient; and hypertrophic scars in 11 patients. The most common cause of their disease was ear piercing. The mean follow-up period was 8.9 months. All surgical procedures were performed under local anesthesia. To compress immediately, a pair of magnetic disks was applied to the anterior and posterior surface of the earlobe. Results: The results were generally good. Major complications, such as recurrence, necrosis, dehiscence, or infection, did not occur. Conclusion: A pair of magnetic disks are useful compression tool in various auricular diseases.

Alloplastic total replacement of the temporomandibular joint (TMJ) was developed in recent decades. In some conditions, previous studies suggested the rationale behind alloplastic TMJ replacement rather than reconstruction with autogenous grafts. Currently, three prosthetic products are available and approved by the US Food and Drug Administration. Among these products, customized prostheses are manufactured, via computer aided design/computer aided manufacturing (CAD/CAM) system for customized design; stock-type prostheses are provided in various sizes and shapes. In this report, two patients (a 50-year-old female who had undergone condylectomy for the treatment of osteochondroma extending to the cranial base on the left condyle, and a 21-year-old male diagnosed with left temporomandibular ankylosis) were treated using the alloplastic total replacement of TMJ using stock prosthesis. The follow-up results of a favorable one-year, short-term therapeutic outcome were obtained for the alloplastic total TMJ replacement using a stock-type prosthesis.

Introduction : Patients with temporomandibular disorder may have various ear-related symptoms. If an excessive load is applied to the ear area due to the skeletal shape of the mandibular condyle or malposition of the disc, an auditory problems may occur. Case report : The patient was referred to our clinic due to the suspicion of temporomandibular disorder from the local otorhinolaryngology clinic. A few days ago, his right ear could not be heard. MRI showed that the left TMJ disc was anterior displacement with reduction, the right TMJ disc was anteromedial displacement without reduction. Also Right mandibular condyle showed sclerotic bone change, subchondral cyst and was compressing the frontal wall of the ear on MRI view. Right TMJ arthroplasty was done under the diagnosis of right TMJ osteoarthritis and osteochondroma. Postoperative intermaxillary fixation was done with SAS screw and elastics for 2 weeks. One month after the operation, hearing and TMJ discomfort were recovered without any complications. Conclusions As seen in this case, hearing loss due to benign tumor-like lesions of the temporomandibular joint should be treated surgically to restore the TMJ function and hearing.
