Amedian mandibular cyst is a type ofcyst that occurs in the midline of themandible, thought to be created by proliferation and cystic degeneration of restingepithelial tissue that is left trapped within the substance of the bone duringembryologic fusion of the two halves of the mandible, along the plane of fusion later termed thesymphysis menti. A true median mandibular cyst would therefore be classified as a non-odontogenic, fissural cyst. The existence of this lesion as a unique clinical entity is controversial,[1] and some reported cases may have represented misdiagnosedodontogenic cysts,[2] which are by far the most common type of intrabony cyst occurring in the jaws. It has also been suggested that the mandible develops as a bilobed proliferation ofmesenchyme connected with a central isthmus. Therefore, it is unlikely that epithelial tissue would become trapped as there is noectoderm separating the lobes in the first instance.[1]
