Study Notes
Face & Scalp Lecture Notes
- This lecture covers the superficial structures of the face and scalp.
- Learning objectives include describing the superficial structures, identifying cutaneous nerves and their territories, identifying facial nerve branches and muscles of facial expression, distinguishing between upper and lower motor neuron lesions of the facial nerve, and describing the blood supply and venous drainage of the face.
- The scalp has five layers: skin, connective tissue, epicranial aponeurosis, loose connective tissue, and periosteum.
- Superficial tissues of the face include skin, fibro-adipose tissue (subcutaneous layer), SMAS (Superficial Musculoaponeurotic System), parotid-masseteric fascia, facial nerve divisions, and buccopharyngeal fascia.
- Major facial nerves (trigeminal) branches and their sensory regions are discussed, including the ophthalmic, maxillary, and mandibular divisions with their terminal cutaneous nerves (supraorbital, supratrochlear, infraorbital, and others).
- Clinical correlates of subgaleal hemorrhage, trigeminal neuralgia, and facial nerve palsy (including Bell's palsy, UMNL vs LMNL, and symptoms like hypo-lacrimation/salivation, ageusia, hyperacusis, and potential issues with the greater/lesser petrosal and chorda tympani nerves, and involvement of the nerves to stapedius, etc.) are included.
- The facial nerve's five major branches (temporal, zygomatic, buccal, mandibular, cervical) and their associated muscles are explained, along with specific muscles like orbicularis oculi, levator labii superioris, etc. A pneumonic (like: "To Zanzibar By Motor Car") can help memorization.
- The facial vasculature, including arteries (facial, maxillary, superficial temporal, posterior auricular, occipital, and ophthalmic, with their associated branches such as superior and inferior labial, etc.) and their associated venous drainage (facial vein, retromandibular vein, occipital vein, posterior auricular vein, and tributaries of IJV and EJV), are detailed. The pathways and functions of various nerves in the face are examined and referenced to diagrams.
- Bell's palsy is a type of facial paralysis.
- Bell's phenomenon is a normal response triggered by forcible eye closure, a defense mechanism.
- The infraorbital, mental, auriculotemporal nerves, and their functions are discussed, related to facial sensation and innervation. The pathways of these major branches are described in diagrams.
- The dermatomes that are served by the trigeminal nerve divisions are addressed. Information on branches serving the skin of the anterior temple, midface, inferolateral orbit, and parts of the internal nose are also included.
