The Stafne defect, first described in 1942,[1] is a depression of the mandible on the side nearest the tongue. It was previously known by many names, including static bone cyst,[2] Stafne idiopathic bone cavity,[3] and salivary gland inclusions in the mandible,[4] but is now known as a pseudocyst. The depression usually allows for the presence of a salivary gland.
Radiographically, it is a well-circumscribed radiolucency with a sclerotic border, and presents without any symptoms. It is usually a developmental defect of the jaw.
An early case of Stafne's defect has been discovered in a 7th century BC adult male individual from Klazomenai, one of the 12 cities of the Ionian League (now in modern Turkey) [5].
