Nerve Supply to the Face and Scalp



A) Facial nerve
  • Comes through the stylomastoid foramen and appears posterior to the parotid gland.
  • Enters the parotid gland to give rise to five terminal branches, the temporal, zygomatic, buccal, mandibular, and cervical branches that radiate forward in the face.
  • Innervates the muscles of facial expression and sends the posterior auricular branch to the muscles of the auricle and the occipitalis muscle.
  • Also innervates the digastric posterior belly and stylohyoid muscles.

B) Trigeminal nerve
  • Provides sensory innervation to the skin of the face.
1) Ophthalmic division
  • Innervates the area above the upper eyelid and dorsum of the nose.
  • Supplies the face as the supraorbital, supratrochlear, infratrochlear, external nasal , and lacrimal nerves.
2) Maxillary division
  • Innervates the face below the level of the eyes and above the upper lip.
  • Supplies the face as the zygomaticofacial, zygomaticotemporal , and infraorbital nerves.
3) Mandibular division
  • Innervates the face below the level of the lower lip.
  • Supplies the face as the auriculotemporal, buccal, and mental nerves
