One hundred and fourty cases of postoperative cysts of maxilla underwent revision-surgeries of Caldwell-Luc operation during the five years from 1975 to 1979.Statistical analyses were done for incidences of male and female, and the affected sides, the age at onset, and years after the initial sinus surgeries.Similar analyses of these items seen in the major reports in the past were compared with the results of the present report.Only the ratio of male to female by incidence showed a changing pattern and the ratio tends to decrease. A brief review concerning the etiology of the cysts was done and it is suggested that the decreasing tendency of male to female ratio by the postoperative cysts of the maxilla is due to the already decreased ratio of male to female at the initial sinus surgeries.Other items such as ratio of right to left, age at onset, and years after the initial sinus surgeries did not show significant changes.
