INTRODUCTION: The retromolar fossa, a triangular area present posterolateral to the 3rd lower molar contains retromolar foramen (RMF) and retromolar canal (RMC), as an anatomical variation in the mandible.
These fibres extend to the base of coronoid process & enter the mandible in retromolar fossa and innervates the lower molar.
The RMF is an inconstant foramen situated in the central portion of the retromolar fossa which is bounded by the anterior border of ramus of the mandible and temporal crest.
The RMF in our study was mostly located in medial aspect of the retromolar fossa close to lingula (Figure 1).
The most common sites of tumors of the minor salivary glands are, in order, the palate, the oral mucosa, and the retromolar fossa
. (2) This distribution probably reflects the higher number of glands in this area.
