Tissue expansion has now been widely used in various soft tissue defects and deformities. It is to reconstruct the lesion site by providing donor tissue of the same color, texture, and similar thickness and sensation with minimal scar formation and minor donor site morbidity. It is achieved through using a temporary expander capable of accumulating normal saline. Internal pressure from expander exerts its force on the flap, which gradually expands to provide additional tissue for reconstruction. We have applied tissue expander in three patients. The first case was soft tissue loss on the left forehead. The second case was multiple scar formation on the left mandibular angle and upper cervical area. The third case was scar contraction on the right cheek. All cases have been successfully reconstructed without complications. 저자들은 1예의 전두부 연조직 결손과 2예의 경부와 안면에 형성된 다발성의 반혼구축 환자에서 조직확장술올 이용하여 양호한 두경부의 연조직 재건을 얻을 수 있었다. 다양한 연조직의 결손이나 변형에서 적절한 증례를 선택하여 올바르게 적용할 경우 조직 확장술은 유용한 재건방법이 될 수 있을 것으로 생각된다.

Purpose : This study evaluated clinical and radiographic results after open reduction and lag-screw fixation of mandibular condyle fractures. Patients and Methods : 26 patients had been treated by lag-screw fixation for madibular condyle fracures via submandibular approach and follow up for over 6 months. The lag-screw used in this study was designed by Eckelt. Results : Radiographically, resorption of the condyle head found in 4 cases (15%) and minimal displacement of the condyle head was found in 3 cases (12%). Post-operative infection were not found in all cases. Clinically, All patiens had a stable occlusion and normal mouth opening (over 40mm). TMD problems with crepitus or some discomfort encountered in 4 patients but tolerable to the patients. Conclusion : Lag screw fixation can be a good option especially high level condylar fractures, however this procedure must be used in cautiously because of slipping of the fragments and possible to resorption of the fragments.

Compound comminuted mandibular fracture is defined as the presence of multiple fracture lines with open wound resulting in many small pieces within the same area. The incidence of mandibular comminution is difficult to determine but reported as 2.7~18.6 % incidence among mandibular fractures. There are controversies in the treatment of mandibular comminuted fractures. Treatment of comminuted mandibular fracture has traditionally involved closed reduction in an effort to avoid stripping periostcum from the bony segments, but rigid internal rigid fixation is used more popular at present. The extent of comminution, displacement of bony fragments and patient general conditions are important factors in decision of the treatment methods. When significant bone displacement is present, it is necessary to reduce these comminuted fragments to an anatomic, pretraumatic relationship to restore facial form and function. In these cases, ORIF allows anantomic reduction of comminuted segments as well as pretraumatic occlusion. Gentle handling of the soft tissue, rigid fixation of bony fragments and adequate immobilization are essential for reducing the complications. This is the report the incidence, causes, complications and treatment of the patients who visited our department for compound comminuted mandibular fractures.

Kaposi s sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi s sarcoma is classified to 4 categories; Classical, African, Epidemic and Transplant type. Epidemic or AIDS categories is found approximately 20 % of all AIDS and has strong predilection for head and neck region. The first case of Kaposi s sarcoma observed in patients with kidney transplants was reported in 1969. Kaposi s sarcoma now accounts for 5% of all tumors associated with transplanted patients and alteration of the immunosuppression may have played a key role in these recipients. The most common site of Kaposi s sarcoma in transplanted patients are extremities but rare in head and neck area. We report a case of Kaposi s sarcoma on the hard palate in the kidney transplantation patient.

골종은 성숙된 골 조직의 성장에 의하여 발생되는 양성 종양으로 안면골에서는 주로 전두동이나 하악골에서 보고되고 있으며 상악동에서는 매우 드물게 보고되고 있다. 이에 저자등은 46세 남자 환자의 좌측 상악동에서 외골종을 경험하였기에 문헌 고찰과 함께 보고하는 바이다. The osteoma is a benign tumor characterized by proliferation of compact or cancellous bone, that may form peripherally in a periosteal location or in a central position. The most common site of peripheral osteoma in craniofacial area is the frontal sinus, but rare in the maxillary sinus. Clinically, this lesion that shows slow growing without symptoms can produce swelling and cause asymmetry. This tumor may arise at any age, but slightly more frequently in men than in women, and more common in young age. Radiographically, this lesion appears as a well-circumscribed radiopacity and histopathologically shows proliferation of either compact or cancellous bone. The etiology of ostemas in the paranasal sinus is unknown, but it has been suggested that they are frequently associated with infection and trauma, and in a certain cases are believed to develop in sinus polyps, which are an inflammatory reaction. The treatment of osteoma is surgical excision, but need not be excised unless it causes obstruction to a sinus cavity or disturbing cosmetically, and this tumor usually does not recur after surgical removal. We report a case of peripheral osteoma on the maxillary sinus in 46 male-patient who came our hospital for discomfort of the left cheek and TMJ area.
