Abstract
The juxtaoral organ of Chievitz (JOOC) is a normal permanent anatomical structure located within the soft tissue overlying the angle of the mandible in the buccotemporal space. It is considered of neuroepithelial origin with no known function. In children, the normal organ may be discovered as a small mass in the cheeks, which may lead to extensive and unnecessary investigations. Chievitz first described JOOC in 1885 while studying human embryos. The aim of this review is to draw attention to the clinical importance of this organ and to provide a concise biography on the scientist who first described it.
