Vebous drainage of the face

Facial vein

10

Dangerous Area of the face

Root of the nose two angles of the mouth

11

Cavernous Sinus Thrombosis

Due to the connection of facial vein to superior opthalmic vein. affects CN 3, 4, 6; ophthalmic and maxillary division of CN 5; internal carotid artery

Junction of falx cerebri with tentorium cerebelli

15

what forms straight sinus

inferior sagittal and great cerebral vein

16

Right Transverse Sinus

From superior sagittal sinus

25

Facial Nerve Branches

1. Greater petrosal Nerve - lacrimal gland (passes the foramen lacerum) 2. nerve to stapedius - supply stapedial muscle, prevent hypermovement of stapes 3. Chorda tympani - joins with the lingual nerve - supply submandibular and sublingual salivary gland; taste sensation from ant 2/3 of tongue 4. post auricular, nerve to post. belly of digastric, nerve to sylomastoid muscle - exit from stylomastoid foramen 5. Parotid Plexus - divides into 5 branches
