The purpose of this report is to describe the clinical, radiographic, and histopathological findings of 41 cases of postoperative maxillary cyst(P.O.M.C.). The surgical ciliated cyst of the maxillary sinus originally reported by Gregory and Shafer in 1958 is a cyst which develops after surgical entry into the maxillary sinus, especially Caldwell-Luc operation. Besides the etiology of the P.O.M.C., its clinical course and treatment is not particular, but each cyst has various epithelial lining which reveals etiology in relation to its origin. We reviewed 41 patients diagnosed as P.O.M.C. at Dept. of Oral and maxillofacial Surgery, Seoul National University Hospital during the period from Jan. 1981 to Mar. 1989, and following results were obtained. 1. The incidence of P.O.M.C. was the highest between the age of 30 and 49 and affected 32 men and 9 women, suggesting the possibility of high incidence in men. 2. The most frequent time period between the radical operation on the maxillary sinus and the visit to hospital were from 10 to 19 year (34.1%) and 20 to 29 year (34.1%). 3. There is no significant difference in the number of each sinus involvement. The number of right sinus involvement was 22 cases(53.7%). 4. The most frequent chief complaint was the facial swelling and tenderness on the buccal cheek area. 5. Radiography showed unilocular(67.9%) and multilocular radiolucency(32.1%). 6. Histopathologically, the lining epithelium of cysts were ciliated columnar epithelium (78.0%), squamous epithelium(31.7%), cuboidal epithelium(4.9%) and columnar epithelium (4.9%). The main epithelium was ciliated columnar epithelium. 7. The surgical treatment method were Caldwll-Luc operation(28cases, 68.3%), modified Caldwell-Luc operation(8 cases, 19.5%), and cyst enucleation and primary closure 4 cases, 9.6%).

This is a retrospective study on lymphangioma of jaw bone and soft tissue. This is based on pathologic reports and clinical charts of 10 patients treated as inpatient and outpatient at Dept. of Oral and Maxillofacial Surgery, College of Dentistry, Seoul National University between 1980 and 1987. The results obtained are as follows. 1. Age distribution of patient ranged from birth to 19 years of age. 2. The ratio of men to women was 50:50. 3. The most common location of lymphangioma was buccal cheek mucosa (40%), tongue (30%) and gingiva (20%) were next in decreasing order. 4. The most frequent misdiagnosis of lymphangioma was hemangioma (50%). 5. On microscopic view, simple lymphangioma was 70%, cavernous lymphangioma was 20% and hemangiolymphangioma was 10%. 6. The mean duration from patient s fiist recognition of lesion to visiting doctor was 7.2 years. The most chief complaint was multiple small. pebble -like masses (40%). 7. Recurrence: 2 cases (20%).

악골에 발생하는 양성섬유골성병소는 예후가 양호하고 섬유이형성증과 구별되는 질환으로 잘알려져있다. 이번 연구의 목적은 본 교실에서 치료된 증례를 중심으로 이들의 임상적, 방사선학적인 특징을 조사하고 치료 후 예후를 추적조사함으로서 이 질환만의 특징과 섬유이형성증과의 관계를 추정해보기 위함이다. 대상은 1984년 1월에서 1994년 3월까지 본 교실에서 양성섬유골성병소로 진단받고 치료받은 증례를 대상으로 하였고 임상병록지와 방사선사진, 조직병리학적인 소견을 참고하였다. 최소 1년에서 최대 11년까지 장기간 추적조사를 시행하였고 통계적 검정은 t-검정을 이용하여 다음과 같은 결과를 얻었다. 1. 양성섬유골성병소는 20대와 30대에 호발하였고, 남녀의 성비는 1:2.2였다. 2. 환자가 주장한 병소의 지속기간은 1년이상이 53.75%로 발병후 장기간 경과한 병소가 대부분이었고, 주소가 종창이었던 경우가 80%로 동통을 호소한 경우는 드물었다. 3. 화골성섬유종의 경우 변연형의 경우가 대부분이었음에 비하여 백악질형성섬유종과 백악골화섬유종의 경우 중심형이 우세하였다. 4. 치료방법은 보존적인 처치를 시행한 경우가 82.5%였고 전체 증례중 재발된 경우는 5%로 이는 치료방법과는 무관하였다. 결론적으로 양성섬유골성병소는 보존적인 방법 후에도 비교적 양호한 예후를 보였으며 재발은 드물었고 악성으로 변화한 증례는 하도 없었다. 이에 본 저자들은 양성섬유골성병소는 섬유아세포가 주된 종양세포로 섬유이형성종보다 분화된 섭유아세포에의한 양성질환으로 생각한다. The benign fibro-osseous lesions (BFO) of the jaw are well known for their good prognosis and their clinical entities defferentiated with fibrous dysplasia. Our objectives of this study are to review these lesions, and confirm their clinical-radiologic-histologic characteristics. We have analyzed the eighty patients who visited in the Dept. of oral and maxillofacial surgery, Seoul National University Hospital, from January 1, 1984 to March 31, 1994 as being diagnosed with benign fibro-osseous lesions. We have compared their clinical features, radiologic findings and treatment methods, and have investigated their individual prognosis. The results were as follows ; 1. The benign fibro-osseous lesions occured frequently in the 3rd to 4th decades, and the ratio of male to female was 1 : 2.2. 2. The subjective duration of lesions more than one year was 53.75%. The chief complaint was swelling in 80% and pain was uncommon. 3. In the case of an ossifying fibroma, the peripheral type was frequent, but in the case of a cementifying fibroma and cemento-ossifying fibroma, the more frequent type was the central. 4. Conservative treatement was used in 82.50% and the recurred cases were 5%. In conclusion, the prognosis of BFO was god after complete enucleation. Recurrence was unusual and malignant change was none. BFO is a more mild lesion than fibrous dysplasia and we suspected that the mesenchymal stem cell is a major contrubuting factor in the development of the lesion.
