Description
Retromolar area in the mandible has considerable surgical importance for dental surgeons. The anatomy of this
area has not received much attention in standard texts of Anatomy. A variant foramen called retromolar foramen has been
described in the literature. This foramen transmits a neurovascular bundle. Presence of this neurovascular bundle poses
a risk in the surgical procedures carried out for impacted lower third molar tooth extraction. The dental surgeon should also
be aware of occasional presence of this neurovascular bundle in retromolar area while infiltrating local anesthetic agents.
The present study was conducted on 71 dry mandibles and 10 cadaveric specimens. In dry mandibles, the
boundaries and dimensions of retromolar trigone were studied. Prevalence of retromolar foramen was recorded. The
distance of retromolar foramen, if present was recorded from posterior border of socket for third molar and second molar
teeth respectively. In cadavers, retromolar areas were dissected and structures related were observed
