Buccal Nerve (N. to M. Buccinator)
Abstract
The following variations in the course and/or branches of this nerve have been reported. Instead of its usual course on the medial side of the temporal muscle, the nerve may pierce the muscle. When absent, the nerve is replaced by the posterior superior alveolar nerves. The buccal nerve may also arise from the inferior alveolar nerve, in which case it emerges from the inferior dental canal through a small foramen in the alveloar border of the mandible, just anterior to the ramus.

The buccal nerve may also arise from the inferior alveolar nerve, in which case it emerges from the inferior dental canal through a small foramen in the alveloar border of the mandible, just anterior to the ramus.
The nerve may arise directly from the gasserian (trigeminal, semilunar) ganglion, in which case it exits from the cranial cavity through a special foramen between the foramina ovale and rotundum.
