The mental nerve is one of two terminal branches of the inferior alveolar nerve, which is rooted in the mandibular division
of the trigeminal nerve.
This artery supplies branches to the medial pterygoid muscle, upper head of the lateral pterygoid, tensor veli palatini, parts of the sphenoid bone, middle cranial fossa, braches of mandibular division
of the trigeminal nerve, and the otic ganglion.
1), involvement of mandibular division
of facial nerve, or suspicious neck lymph nodes metastasis.
of trigeminal nerve was involved in 43.3% and maxillary division in 40% of the cases.
The branches of mandibular division
of inferior alveolar nerve may arise high in the infratemporal fossa as explained by Ikeda et al  in his study.
