Clinical study of 133 cases (140 sides) of the postoperative cyst of the maxillae was performed by the analysis of such clinical data as chief complaints, age at onset, years after the initial sinus surgeries and the affected sides. Radiographic evaluations as to the sites of the cysts were performed using polytomographies of both the frontal and lateral sections. By comparing the cysts with the occult (clinically silent cysts), it was suggested that the anlage of the cyst originates, with predilection, at the medial ventral aspect of the sinus and further development of the cyst follows with the elapse of time. The sites of the cysts and other clinical statistical data were compared. Compression at the medial orbital floor gives rise to epiphora and subsequent extensive compression of the orbital floor produces diplopia and exophthalmos. Limited compression at the lateral orbital floor is seen by polycystic cases and produces no orbital signs. Compression of the sinus floor was little related to the oral signs including toothache and gingival swelling. The extension of the cysts to the sinus floor was restricted when the initial sinus surgeries were performed before the age of 15.
