Inferior alveolar artery and nerve enters into the foramen and inferior alveolar vein comes out of it. Dissection studies on 16 male and 4 female cadavers suggested that inferior alveolar nerve was medial to inferior alveolar vessels and inferior alveolar artery was anterior to inferior alveolar vein. Knowledge of interrelationship of structures at mandibular foramen is important for dental surgeon or oral surgeons while giving the inferior alveolar nerve block.
