or reviewed in the dental literature. However, these anatomical variations draw special attention in the recent years in oral surgery and clinical dental practice. The RMF is an inconstant foramen situated in the retromolar fossa, and it is often linked to the RMC. It presents morphologic and morphometrical variability. The introduction of advanced dental surgical procedures in this area, such as bone graft techniques, in which a surgeon often chooses the mandibular ramus as the donor site, has increased the probability of damaging the buccal nerve and other complications such as sensory deficits. To date, despite an exhaustive review of the literature, few links have been established between RMC or RMF and Buccal Nerve (BN) and bone harvesting techniques in this area. The purpose is to present a clinical case that shows a retromolar foramen contains a nervous branch originating from the buccal nerve instead of the infra-alveolar nerve and its surgical incidence in oral surgery.
