Mental foramen (MF) is an important landmark to consider for surgical procedures performed in the mandible. Anatomical variations such as accessory mental foramen are considered to be a rare occurrence. Only a few cases have been reported in the literature. The purpose of this article is to present a case with Cone-beam computed tomography (CBCT) images and suggest that preoperative cone-beam computed tomography (CBCT) would aid in the assessment of anatomical variations and prevent any post-operative complications.
