Morphometric study of mandibular foramen in dry human mandibles



The mandibular foramen is located on the medial surface of the ramus of mandible through which inferior alveolar nerve enters the mandibular canal. This study was undertaken in 238 mandibles and the distance of the foramen from the bony landmarks was measured. The mean distance of the mandibular foramen from anterior border of ramus, posterior border of  ramus, gonion and condyle of the mandible were 16.47mm, 10.23mm, 21.07mm and 36.45mm respectively. Awareness of location of mandibular foramen is essential in dental   anaesthesia and to avoid complications during mandibular            surgeries.
