Cortical defects in the mandibular sulcus.
Examination of 5366 dry mandibles at the Smithsonian Institution revealed three cases of unilateral lingual defects superior to the mandibular foramen. The differential diagnosis includes a neuroma, neurolemmoma, hemangioma, or aneurysm of the inferior alveolar artery. The clinical significance of a vascular neoplasm or aneurysm would be the likelihood of increasing the risk of injecting the anesthetic solution directly into a blood vessel.
