Being knowledgeable of neurovascularization of anterior mandible is crucial for successful local anesthesia and for safe minor and major oral surgeries of this part. The first case was 62 years old and was found to have two accessory mental foramina with buccal emergence on the left side and two accessory mental foramina with buccal and lingual emergence paths on the right side (overall five mental foramina). Incisive nerve plexus with multiple cephalic branching was obvious on both sides. The second case was 60 years of age and had two lingual foramina on the lingual side with two accessory foramina on the buccal side of the symphysis. Considering our findings, a pre-operation limited cone beam computed tomography is suggested to avoid inadvertent damage, especially when planning a surgery in the mandibular inter-mental region.
