[The post-operative maxillary cyst: report of 14 cases].
The author observed 11 patients with buccal symptoms and history of surgical intervention for maxillary sinusitis who had come to KNUH during 3 years (1986. 6-1989. 5). As a result of careful analysis of clinical, radiological and histopathological findings, the author diagnosed them as postoperative maxillary cysts. The obtained results were as follows; 1. On the 11 patients, 6 were male and 5 were female and age distribution was from 35 to 53 years. Average age of patients was 45-year-old. 2. The most frequent chief complaint was buccal symptom type and 5 patients complained in the right side and 6 in the left. 3. The initial surgery was performed by means of the Caldwell-Luc's method for maxillary sinusitis in all cases and the duration between the initial radical operation and the onset of cyst was mainly from 10 to 35 years. The average was 24 years. 4. In radiological observations, bilateral lesions were noticed in the 3 patients. And 7 lesions were found in the right side and 7 in the left among the 14 lesions in 11 patients. Generally these lesions were shown monolocular cystic radiolucency with a well-defined, smooth margin and without marginal sclerosis. 5. Histopathologically, these cysts were basically composed of pseudostratified ciliated columnar epithelium and squamous metaplasia was occasionally founded.
