oris
mouth
palpebrae
eyelid
mentum
chin
branches of cervical plexus
lesser occipital (around occipital bone)
great auricular (around ear)
transverse cervical (front of neck)
supraclavicular (shoulder area)
dorsal root-like ganglion containing cell bodies of trigeminal afferents
Gasserian/Semilunar ganglion
caused by HSV type 1 and presents as chickenpox in children
Shingles
where does shingles virus reside
gasserian ganglion
stress will cause virus to travel on branches of trigeminal to one side of the face and it also affects what
vision
a person w/ shingles who is around an unvaccinated for chickenpox person, what could happen to unvaccinated person
they could get chickenpox
treatment for shingles
acyclovir, valacyclovir
this is caused by nerve covering destruction
Trigeminal neuralgia/Tic Douloureux
treatment for trigeminal neuralgia
medicine
gamma knife surgery
nerve ablation
arteries of the face
external carotid a.
internal carotid a.
branches of external carotid a. in the face
superficial temporal a.
transverse facial a.
facial a. (kink)
branch of internal carotid a. in the face
ophthalmic a.
main vein of face
internal jugular v.
branches of internal jugular v.
facial v.
superficial temporal v.
superior ophthalmic v.
pterygoid plexus
where does venous drainage of the face happen
cavernous sinus
what makes up danger zone of face
the veins of the face and cavernous sinus
skin abscesses caused by staph
furuncles (boils)
furuncles may produce what kind of clot
cavernous sinus thrombosis
lymphatic drainage of the head and neck really all drain to
deep cervical nodes to jugular trunk; then back into veinous system
2 important nodes along internal jugular vein
jugulodigastric
juguloomohyoid
where does parotid duct (Stenson’s duct) drain to
vestibule of the mouth (in the cheek)
what nerve can be damaged during a parotid gland tumor removal
CN VII branches
parotid/stenson’s duct pathology summary
stone in the duct
this nerve carries postganglionic parasympathetics to parotid gland and sensory to side of face anterior to the ear
auriculotemporal n. (branch of CN V3)
this nerve carries sensory to area below and in front of the ear and then postganglionic sympathetics to sweat glands
great auricular n.
Describe Frey Syndrome (deals with Parotid gland)
laceration cuts both nerves
regeneration of auriculotemporal n. causes whole face to sweat
inflammation of gonads
orchitis
swollen parotid glands
mumps
when to give mmr vaccine
1st dose and 1 year
2nd dose at 4 yrs
mumps can spread and cause infections where
meningitis (meninges of brain)
orchitis (gonads)
exits at stylomastoid foramen
facial nerve (CN VII)
innervates posterior belly of digastric and stylohyoid m.
CN VII
upper divisions of facial nerve
temporal
zygomatic
buccal branch
lower divisions of facial nerve
buccal branch
marginal mandibular
cervical
temporal muscles that furrow the brow and close the eye
frontalis
orbicularis oculi m.
zygomatic muscle that closes the eye
orbicularis oculi m.
buccal branch muscles that elevate the lip
buccinator m.
orbicularis oris
buccal branch muscle that depresses the lip
buccinator m.
marginal mandibular muscle that puckers the lip
orbicularis oris
cervical muscle
platysma
most common cause of bell’s palsy
herpes
symptoms of bell’s palsy
(all on one side of the face)
can’t close eye
drooping
drooling
hyperacusis (lose stapedius m.)
loss of ability to taste (lose chorda tympani m.)
SMAS (deals with facelifts)
Superficial
MusculoAponeurotic
System
SMAS is between what layers
dermis and investing layer and connects to superficial fat
