Abstract　： [Abstract] A cyst appeared between the upper lateral incisor and canine is called "intermaxillary cyst" and it is believed to be nonodontogenic. This site does not always correspond to the incisive suture. The intermaxillary cyst is sometimes called "globulomaxillary cyst, " since it is believed to be derived from the remnants of the fused epithelial wall of globular and maxillary processes. The united part of the globular process and maxillary process does not correspond to the incisive suture or the junction of the premaxilla and maxilla. This cyst in question would be embryologically derived mainly from the disintegrated dental lamina, and partly from the disintegrated nasopalatine duct. In this sense, most of the globulomaxillary cysts are odontogenic. Nasoalveolar cysts would not be derived from the fused epithelial wall of three facial processes, but they would be derived mainly from the disintegrated accessory lamina (which corresponds to the marginal tooth lamina in reptiles) from which the mesiodens develops, and partly from the ectopic disintegrated nasolacrimal duct, or from the ectopic nasal epithelium of the primary nasal cavity close to the transient area connected to the secondary nasal cavity. The median cyst in the lower jaw could be derived from this accessory dental lamina.
