Cystic lesions of the maxilla could be generally divided etiologically and anatomically into those related or not related to the teeth. During the past eight years, two hundred cases of cystic lesions of the maxilla were observed. Among them, 178 cases (89%) were postoperative maxillary cysts. Three cases of cysitc lesions of the maxilla were related to the teeth. The summary of our investigations is as follows: 1. Two cases of large radicular cysts had complaints, resembled those of postoperative maxillary cysts. And one case of postoperative maxillary cyst with the dental infection. 2. Orthopantomography was most helpful for the diagnosis. 3. An examination of the dental pulp by the electric pulp tester was important. 4. Filling of the root canal for the nonvital teeth required the extirpation of the maxillary cyst. 5. The first CALDWELL-LUC operation must be performed carefully in order to aboid causing a maxillary cyst.
