Infraorbital foramen (IOF) located bilaterally within the maxillary bone about 1 cm inferior to infraorbital margin is a vital landmark when delivering local anesthesia and during surgical interventions in midface region. A total of 122 foramina 61 cone beam computed tomographic (CBCT) images 32 females 29 males age range 17 were analyzed determine shape, direction, presence accessory foramina, size precise position IOF relation orbital (IOM), midline (MM), lateral nasal wall (LNW), alveolus (ALV) teeth group Sri Lankan people.
