Incidence of Retromolar Canal in Egyptian Population Using CBCT “A Retrospective Study”

Abstract

The nerve of RMC is an anatomical variation of the mandible in the retromolar area which is thought to arise from accessory IAN or aberrant long buccal nerve, neurovascular bundle that runs through the RMC, contains veins, arteries and myelinated nerve fibers The course RMC varies from one individual to the other and was found to exhibit either a vertical or a horizontal course. It may also appear as an independent canal that starts from a separate foramen in mandibular ramus and ends in the retromolar fossa with the opening of RMF. In other instances, its course may start from the retromolar fossa and end in the radicular portion of the lower third molar with no evident relation with the IAN.
