A clinical investigation of monocystic and polycystic types of postoperative cysts of the maxillary sinuses in 107 cases (114 sides) was done. The age at the initial sinus operation and the duration from the initial surgery to the revision surgery for the postoperative cysts did not show the significant difference between monocystic and polycystic types. From the polytomographic findings, the polycystic type was classified into central and peripheral ones according to the location in the maxilla. The central cyst was also classified into central-expansive and central-basal types. The central cyst was found in 90% of polycystic type, and in 70% two cysts were found the one beside or the one above the other. In three types, monocystic, central-expansive polycystic and central-basal polycystic, the first two types showed the oral signs (toothache, swelling of the gingiva, etc) more frequently than the last one.
