The submandibular fossa (SF) is an important an - atomic landmark of the mandible, where the sub - mandibular gland resides. During dental practice, particular attention is paid to SF when conducting the placement of dental implants and other surgi - cal procedures. Any procedure undertaken has to be carried out with great care and attention in or - der to avoid perforation of this area. Anatomical variations of SF can occur, such as a deeply prom - inent and flat area with no depression. On very rare occasions, the mylohyoid ridge cannot be detected radiographically or bimanually as the observation of this variation is not always possible using a con - ventional radiograph. However, as a modern imag - ing resource, cone beam computed tomography (CBCT) allows an accurate three-dimensional as - sessment of SF as well as the identification of its degree of concavity...
