Face And Scalp Anatomy

Front 1

Clinical signs of Bell's palsy

Back 1

Unilateral flaccid paralysis of muscles innervated by facial nerve. Drooling, inability to smile, life eyelid, raise brow. Hyperacusis (acute hearing) is sometimes a symptom.

caused by lesion of facial nerve.

Front 2

Orbicularis oculi

Back 2

winking muscle

Front 3

Clinical signs Frey's syndrome

Back 3

abherent reinnervation causes profuse sweating over cheek, temple, side of face unilaterally. Caused by reinnervation of trigeminal nerve.

Front 4

zygomaticus major

Back 4

smile muscle!

Front 5

trigeminal neuralgia

Back 5

sudden pain along course of trigeminal nerve, radiating to maxillary or mandibular area. Caused by abherrant blood vessels, aneurysms, chronic meningeal inflammation, or brain tumors which compress the trigeminal nerve at the base of the brain.

Front 6

danger area of the face

Back 6

area of face near nose drained by facial veins. Skin infections may spread to cavernous sinus via facial vein, pterygoid sinus plexus, and ophthalmic veins.

Front 7

Scalp hemorrhage

Back 7

laceration of arteries in dense subcutaneous tissue which contract or retract and remain open

Front 8

metopic suture

Back 8

divides the frontal bone in halves, usually fuses after birth, but persists unfused in 8% of adults

Front 9

facial fascia

Back 9

because no distinct deep fascia, facial lacerations gape

Front 10

black eye

Back 10

blood accumulation in loose connective tissue following injury

Front 11

herpes zoster ophthalmicus

Back 11

viral infection of face along ophthalmic nerve. cornea often involved. infection can spread within the orbit to CN III, IV, and VI and cause partial paralysis of their associated muscles

Front 12

scalp lacerations

Back 12

bleed profusely because of extensive anastamoses and because lack of venous valves. Infections of scalp are potentially dangerous because scalp emissary veins communicate with intracranial venous dural sinuses.
