Purpose: Dermoid cysts are benign neoplasms that are derived from both ectoderm and mesoderm. Approximately 7 percent of all dermoid cysts occur in the head and neck, as most common sites are the lateral ends of the eyebrows, the midline in the nasal root and neck. Rarely they can be found in the frontal sinus, temporal bone, maxilla and the floor of the mouth. Dermoid cysts in the temporal fossa are extremely rare. We experienced a characteristic dermoid cyst that occupied the temporal fossa. Methods: A 16-year-old man had a progressive enlarging mass on the left eyebrow. Computerized tomographic scan showed a bulging mass in the temporal fossa, and it had the density similar to that of fat. The size of the mass was $3{\times}3{\times}2cm$, and it was composed of high density of fat with clear margin. There was no bony invasion, but the mass was fixed on bone. Results: We performed the surgery through coronal incision under general anesthesia. Because the mass was closely connected with temporal fat pads, we removed this mass with some portion of temporal fat pads, avoiding damage to the facial nerve. The postoperative course was ordinary without complication. Conclusion: The reports about dermoid cyst on the temporal fossa is uncommon. However, if there is a mass in the temporal fossa which has the density similar to that of fat in CT scan, we should consider the possibility of dermoid cyst. We suggest that excision through coronal incision with bewaring temporal fat pad can induce good result.

상악 전치부 치료 시에는 다양한 구도 속에서 체계적인 진단을 통해 적절한 형태와 배열, 색조를 가지는 수복물을 제작하여 심미적으로 환자가 만족할 수 있는 결과를 이끌어내야 한다. 이를 위해 치아 구도, 치은구도, 안면구도, 치아-안면 구도의 4가지 구도 속에서 조화를 이루는 진단 및 치료계획이 필요하다. 심미적인 욕구가 강한 경우, 주관적인 환자의 심미안을 만족시키면서 기능적인 부분을 확인하기 위해, 적절한 임시 수복물을 제작하여 기능적, 심미적 측면의 평가가 필요하다. 최종 보철물 제작에 이중 스캔을 이용하여 임시 수복물의 정보를 반영할 수 있다. 본 증례는 상악 전치부가 비심미적인 환자에서, 체계적인 심미 분석 하에 임시 수복물을 제작하고 기능적, 심미적 측면을 평가 및 수정하여, 이중 스캔을 통해 임시수복물의 정보를 최종 수복물에 반영 후 최종 수복한 증례이다.

The midline nasal dermoid cysts are rare congenital neoplasms, which are diagnosed frequently in childhood. Masses are often noticeable at birth gaining size over time with recurrent infections and usually arise from the nasal cavity or lower 1/3 of the nasal dorsum. CT scan as the primary investigation is helpful to determine accurately the size and extent of the lesion as well as the integrity of adjacent bony structures. MRI scan is recommended to rule out an intracranial extension or sinus tracts. Treatment of choice is the complete surgical excision preserving the cyst wall. Here in, we present an unusual case of nasofrontal dermoid cyst in a 19-year-old boy without radiographic evidence of transcranial extension. In this case, we surgically removed nasofrontal dermoid cyst via transcolumellar approach. We also corrected saddle nose deformity after mass removal. Therefore, in this case, we experienced a successful case in which the nasofrontal dermoid cyst was totally removed without facial scar and deformity.

We reviewed 30 cases of superior vena cava syndrome in adult patients who were seen at the Yeungnam University Hospital from January 1985 to June 1990. The results were as follows : 1. The male-to-female ratio was 6.5:1, and the most patients were in the age group between the sixth and seventh decades. 2. The most common symptoms were dyspnea (87%) and followed by cough (63%), facial swelling (63%) and chest pain (44%) and the physical signs were dilated neck vein (97%), facial edema (93%) and facial flushing (45%) in order of frequency. 3. The simple chest x-ray findings were superior mediastinal widening (90%), right hilar mass (77%) and pleural effusion (31%). 4. Diagnosis was made by history and physical examination (100%), chest C-T scan (100%), simple chest x-ray (97%), bronchoscopy with biopsy (40%) and so on. 5. 21 cases of patients were confirmed by histology : 14 cases (46%) of bronchogenic ca. 4 cases (14%) of lymphoma, 3 cases (10%) of metastic lung ca. Of bronchogenic ca. small cell ca was 7 cases (23%), squamous cell ca, 5 cases (17%), and unclassified ca was 2 cases (6%). 6. In response of treatment, the clinical improvement was achieved in 18 cases with radiotherapy alone. 1 case with chemotherapy only, and 6 cases with radio-chemotherapy.

디지털 기술은 점차 그 영역을 넓혀 치의학의 여러 분야에 큰 영향을 미치고 있다. 최근 디지털 치의학에서는 다양한 삼차원적(3D) 이미지 데이터를 하나로 중첩시켜 진단 및 보철물 제작에 활용하는 것의 중요성이 대두되고 있다. 안면 스캔, 구내 스캔, 하악 운동 기록(mandibular movement recording) 등의 데이터를 통합하면 가상 환자 모델을 구성할 수 있다. 가상 환자(Virtual patient)란 구내 및 구외 연조직, 잔존 치열, 동적 교합 등 디지털 3D 진단 데이터를 통합하여 형성되며 이를 통해 보철 치료의 결과 등을 가상으로 시뮬레이션을 시행할 수 있다. 본 증례에서의 환자는 37세 여성 및 55세 여성 환자로 각각 기존 보철물의 외형이 틀어진 것 같다는 주소와 근관치료 후 전치부 보철물의 재제작을 주소로 내원하였다. 각 환자에서 3D 안면 스캔을 채득하였으며, ARCUS Digma 2 (KaVo Dental GmbH, Biberach an der Riss, Germany)를 통해 환자의 하악 운동을 기록하였다. 수집한 데이터를 computer-aided design (CAD) 소프트웨어(Exocad dental CAD; exocad GmbH, Darmstadt, Germany) 상에서 하나로 통합하여 가상 교합기에 옮겨 디지털 가상 환자를 형성하였다. 이를 통해 임시 고정성 보철물을 디자인하고 수복하여 평가하였으며, 최종수복물로 옮겨 심미적, 기능적으로 만족할 만한 결과를 보였기에 이를 보고하고자 한다.

Purpose: Sebaceous carcinoma is a rare malignant tumor that occurs mostly in head and neck regions. Early diagnosis and treatment are necessary because it tends to be locally aggressive and goes through distal metastasis with fast progression. This study presents reliable surgical methods for sebaceous carcinoma in head and neck regions. Methods: Three patients were included in this study. First, a 61-year-old woman visited the hospital with a yellow-colored, slowly growing mass on the left ala. A 54-year-old woman had a brown-colored mass on her right preauricle. Last case was a 62-year-old man who had a yellow-colored mass on his scalp. CT scan and punch biopsy were done. All cases were diagnosed as sebaceous carcinoma. The lesions were resected with 10 mm safety margin and various regional flaps were used for reconstruction. Results: Histological examination revealed sebaceous differentiation and local invasions. Postoperatively, all patients did not suffer from complication and no recurrence was found. Conclusion: We recommend early wide excision with an enough safety margin, and a regional flap as a treatment of sebaceous carcinoma.

The arteriovenous malformation, an uncommon lesion, is a direct communication between an artery and a vein that bypasses the intervening capillary bed. The authors experienced two cases of arteriovenous malformation in 17-year-old and 18-year-old female patients who had suffered from mandibular pain and gingival bleeding. As a result of careful analysis of clinical and angiographic radiological examinations, we diagnosed them as arteriovenous malformations, and the results were as follows : 1. Main clinical symptoms were dull pain and gingival bleeding on the mandibular body area, and reddness, pain on palpation, thrill and palpitation in the lesional sites were also observed. 2. Radiographically, well-defined radiolucent lesions with multiple osteolytic defects were observed. In radio-nuclide scan, increased uptakes of radioisotope were observed in the lesional sites. 3. Increased venous shunt supplied by the facial, lingual and inferior alveolar arteries was observed in angiography. After embolotherapy was performed, no recurrence was reported during 3 to 6 months follow up.

In the present study, a fibular osteotomy guide based on a computer simulation was applied to a patient who had undergone mandibular segmental ostectomy due to oncological complications. This patient was a 68-year-old woman who presented to our department with a biopsy-proven squamous cell carcinoma on her left gingival area. This lesion had destroyed the cortical bony structure, and the patient showed attenuation of her soft tissue along the inferior alveolar nerve, indicating perineural spread of the tumor. Prior to surgery, a three-dimensional computed tomography scan of the facial and fibular bones was performed. We then created a virtual computer simulation of the mandibular segmental defect through which we segmented the fibular to reconstruct the proper angulation in the original mandible. Approximately 2-cm segments were created on the basis of this simulation and applied to the virtually simulated mandibular segmental defect. Thus, we obtained a virtual model of the ideal mandibular reconstruction for this patient with a fibular free flap. We could then use this computer simulation for the subsequent surgery and minimize the bony gaps between the multiple fibular bony segments.
