There are several kinds of maxillary cysts, but it is sometimes difficult to differetiate among them, because there is no useful clinical classification of maxillary cyst.
Recently we treated four patients with maxillary cysts. In the first we used fatty tissue for filling the dead space in the maxillary bone after extirpating the cyst.
The results were very good. We propose a new classification of maxillary cysts on the basis of our operative results.
