case_images: A 62-year-old patient referred was found to have one main MF and two AMF with buccal emergence on the left side [Figure 1a and b]. Examination of the right side revealed two mental foramina with buccal opening and one with lingual emergence [Figure 1c and d].
case_images: (a-d) Communication of lingual AMF with IANC and buccal MF. Reconstruction of four continuous cross-sectional images. MF: Mental foramen, AMF: Accessory mental foramen, IANC: Inferior alveolar nerve canal

case_images: This lingual mental foramen was in communication with the main IANC and MF and a crestal extension of IANC [Figure 2].
case_images: (a) Panoramic view of patient's mandible. Note multiple branching incisive nerve on both sides with crestal extension. (b-d) Communications of the upper and lower lingual foramina and a crestal opening. Reconstruction of three continuous cross-sectional images. LF: Lingual foramen, ALF: Accessory lingual foramen

case_images: As evident in the panorama view, a communicating neural bundle existed between mental foramina, incisive canals and crestal opening of their vertical extension [Figure 3].
