Fissurai cysts are believed to be derived from entrapped epithelium in the fusion lines of the frontonasal and maxillary processes during facial development. Because of their histologic similarities, fissurai cysts are distinguished from one another by anatomic locations. They are classified as midline or lateral cysts.

Recently we experienced three cases of fissurai cysts, which were diagnosed as nasolabial cyst, globulomaxillary cyst and nasopalatine cyst by history, physical examination, radiologic studies and histopathologic examination. The cysts were successfully enucleated by sublabial approach using marginal gingival incision. So we report these cases with review of literature.
