Nasopalatine cyst

Overview
This cyst, also known as a nasopalatine duct cyst, occurs in the median of the palate, usually anterior to the first molars. It is the most common type of oral non-odontogenic cysts. Radiographically, it appears as a heart-shaped radiolucency. It is usually asymptomatic, but may sometimes produce an elevation in the anterior portion of the palate.

The median palatal cyst has recently been identified as a possible posterior version of the nasopalatine cyst.

Treatment
It is treated by excision.
