Nasopalatal Cyst - A Case Report

Nasopalatal cyst (NPC) is rare but most common among the developmental, non-odontogenic cysts of the jaws. NPC also called as incisive canal cyst, Nasopalatal canal/duct cyst. It is unique in that it develops in only a single location, in the midline anterior maxilla. . NPC was first described by Mayer in 1914. It arises from the embryonic ducts of scrapa and stenson. It accounts for about 5-10% of the jaw cysts and 1% of the population. Majority of the cases occur between fourth to sixth decades of life. Males are more commonly affected than the females. Most of NPCs are asymptomatic. Usually patient complains of palatal swelling, upper anterior teeth displacement, sub-labial swelling, and low grade pain. Various combinations of swelling, discharge and pain may occur. Histopathologically, the type of cystic lining varies according to the location involved (palatine, nasal or intermediate). The cuboidal cystic epithelial lining is very rarely seen. NPCs are usually treated by enucleation, in case of large cysts, marsupialization may be considered before definitive enucleation. Recurrence rate ranges from 0% to 11%. we report a case of nasopalatal cyst in 38year old lady. Keywords: incisive canal cyst, developmental cyst, cysts of oral cavity
