Anatomic Variations


The normal flexibility in morphology and topography of body structures may be termed as an anatomical variation. This manuscript, aims to present a unique discovery of ‘coronoid foramina’ bilaterally along with bilateral accessory foramina over the ‘lateral aspect of the ramus of the mandible’ which has never been seen or documented in the literature so far in a live patient. It is noteworthy to realize a trait of phylogenetic context in these discoveries.


Mandible Coronoid foramina Lateral accessory foramina Mandibular foramen Mandibular canal
