Mucocele of the paranasal sinuses is a benign, slow-growing, expansile lesion. Maxillary sinus mucoceles are usually associated with painless bulging of the cheek; however, orbital expansion is rarely observed. Maxillary sinus mucoceles can be classified as primary or secondary according to their etiology. An impediment to sinus ostium ventilation is thought to be the cause of primary mucocele, while sequestering of residual mucosa after surgery in the wound and long-term retention of tissue fluid have been suggested to lead to the formation of secondary mucocele. This report presents 2 cases of primary and secondary mucoceles, with a focus on radiographic features. As primary and superiorly positioned secondary maxillary sinus mucoceles are uncommon and their close proximity to the orbit predisposes the patient to significant morbidity, the authors expect that this report will contribute to a better understanding and diagnosis of maxillary sinus mucocele involving the orbit.

Purpose: The authors report unusual one case of a patient presenting with maxillary sinus mucocele who had underwent Lefort I procedure 7 years ago. Methods: Case report and literature review Results: A 25 year old man came to us with fullness, pain and nasal obstruction on his left cheek area. He had a history of multiple operations due to cleft lip and palate since birth. Two jaw surgery was performed for correcting class III malocclusion 7 years ago. Computed tomography showed haziness, and fluid filled cystic mass on left maxillary sinus. Nasoendoscopy revealed the bulging of inferior turbinate and mucosa coincided in medial wall of maxillary sinus. Antrostomy with Caldwell-Luc approach was performed. Mucin contaning brownish exudate was leaked out. Severe inflammation of maxillary inner wall and exposure of 2 screws fixed previously were noticed. The curettage and marsupialization were accomplished. The symptoms of patient were improved after that procedure. Conclusion: Maxillary sinus mucocele is related with Lefort I procedure and it may occur even long after that procedure.

Maxillary sinus mucocele can occur due to many medical factors such as chronic infection, allergic sinonasal disease, trauma, and previous surgery. However, it occurs mainly after Caldwell-Luc operation, usually more than 10 years after surgery. There are a few cases of maxillary sinus mucocele with ocular symptoms. Also, a case causing ocular symptoms because of invasion to the orbital floor is rare. Therefore, we report a case of a 55-year-old male patient who underwent Caldwell-Luc operation about 30 years ago. Then, symptoms such as exophthalmos, diplopia, and visual disturbance developed suddenly 3 months prior to admission. Computed tomography showed a cyst invading the orbital floor which resulted in eyeball deviation. The orbital floor defect measured approximately $2.5{\times}3.3cm$. Maxillary sinus mucocele was removed through an endoscopic approach. After this, we reconstructed the orbital floor through a subciliary incision. Observation was carried out after three years, and ocular symptoms such as diplopia and exophthalmos did not recur.

This study was designed to evaluate the correlationship between radiologic classifications of cysts in oral region and glycosaminoglycan analysis of cystic fluids using cellulose acetate electrophoresis. The materials for this study consisted of 37 cases-8 periapical cysts, 10 dentigerous cysts, 10 primordial cysts, 2 residual cysts, 3 incisive canal cysts, 2 post-operative maxillary cysts, 1 mucocele on maxillary sinus, & 1 unicystic ameloblastoma-diagnosed as cystic lesions radiologically. The obtained results were as follows: 1. At the stepwise discriminant analysis, four variables-low mobility material, heparin, hyaluronic acid, & dermatan sulfate-were used to define diagnostic model for the odotogenic cyst. The model produced a sensitivity of 100% and a specificity of 85%. 2. The intensities of heparin and chondroitin-4-sulfate were greater in dentigerous cyst than periapical cyst(p<0.05). The intensity of chondroitin-4-sulfate was greater in primordial cyst than in periapical cyst(p<0.05). 3. It showed no statistically significant difference in glycosaminoglycan of the cystic fluids between dentigerous cyst and primordial cyst(p>0.05). 4. On the fluids of the cysts originated from maxillary sinus, there were especially high intensities of heparin and dermatan sulfate, and low intensity of chondroitin-4-sulfate. 5. On the fluids of unicystic ameloblastoma, there were high intensity of dermatan sulfate and low intenity of chondroitin-4-sulfate.

영남대학교 의과대학 부속병원 안과에서 1984년 3월부터 1994년 8월까지 병리조직검사로 확인된 안와종양 95례를 대상으로 임상적 고찰을 실시하였다. 안와종양의 발생빈도는 성별로는 남자가 46명(48.4%), 여성이 49명(51.6%)으로서 유의한 차이를 보이지 않았으며, 연령분포는 양성종양의 경우 전 연령층에 걸쳐 고루 분포하였고, 악성종양의 경우 10세 미만과 50-60대에 특히 많은 발생을 보였다. 광학 현미경으로 살펴본 병리조직학적 검사상 양성 대 악성의 비율은 82% : 18%로서 다른 연구에서 보다 양성종양의 비율이 높았다. 종류별로는 피부지방종(20례, 21%), 유피낭(11례, 11.6%), 점액류(8례, 8.4%), 지방종(7례, 7.4%), 다형생 선종(5례, 5.3%) 순이었다. 양성종양은 성인의 경우 점액류, 유피낭, 다형성 선종, 해면혈관종 순의 발생빈도를 보였고, 소아의 경우 피부지방종, 유피낭, 지방종, 망막모세포종 순의 발생빈도를 보였다. 악성종양은 망막모세포종 3례, 악성 흑색종 2례, 피지선암 2례, 상악동암 2례 등이었다. 악성종양중 사망한 경우는 17례 중 8례 (47.0%)로서 모두 이차성 혹은 전이성 안와종양이었다.
