What nerve pierces Buccinator?
buccal nerve
The Trigeminal Nerve On its extracranial course, it divides into three main branches: the buccal, mental, and auriculotemporal nerves. The buccal nerve pierces the skin on the face behind the ramus of the mandible, passes in front of the masseter, and innervates the skin anteriorly of the buccinator muscle.
