1/5 of pts w/Multiple Sclerosis also have Bell's Palsy

3

Trigger events

-occur 75% of cases and include:
-VIRAL INFECTION (herpes)

-local/systemic infections
-ischemia
-acute otitis media
-pregnancy

4

gender/age demographics for Bell's Palsy

-middle aged women (71%) > men

-in kids: secondary to viral infection, lyme disease, earache

5

Tx and prognosis for Bells Palsy

-82% recover slowly over 6mo
-histamine, steroids, HBO, surgical decompression, ocular Abs and artificial tears
-SELF LIMITING

6

what do neuralgias and headaches share in common

-both may mimic pain of dental origin
-need to r/o dental inflammatory diseases

7

age of onset for trigeminal neuralgia

avg age 50

9

what other neuromuscular disease is trigeminal neuralgia assoc with

4% have MS

10

name two disorders of facial pain that are associated with MS

-Bell's Palsy
-Trigeminal Neuralgia

11

Trigger points for trigeminal neuralgia

-nasolabial fold
-vermillion border
-periorbital skin
-alveolus

12

main branches affected by trigeminal neuralgia

CN V: mostly max/mand but opthalmic can also be affected

13

Criteria for Trigeminal Neuralgia Dx

-abrupt attack initiated by a light touch and a specific, CONSTANT, trigger point
-extreme paroxysmal lancinating pain
-duration of single spasm < 2min but may repeat
-pain is limited to 1 or more branches of CNV; NO MOTOR DEFICIT
-trigger point refractory to additional attacks for several minutes

14

what is trigeminal neuralgia often misdiagnosed as

dental pain

15

What disorder is characterized by paroxysmal facial pain that is accompanied by excess lacrimation, conjunctival injection, and intense headache?

SUNCT syndrome

16

what does SUNCT syndrome stand for? --> EXAM

-Short Lasting
-Unilateral
-Neuralgiform headache
-Conjunctival injection
-Tearing

17

What CN does Glossopharyngeal Neuralgia affect

CN IX

18

chronic pain associated w/VZV (shingles)

Postherpetic Neuralgia

19

constant burning sensation over nerve distribution w/episodic stabbing pains

Postherpetic Neuralgia

20

Facial paralysis seen in association with herpes zoster of the face or external auditory canal.

Ramsay Hunt Syndrome

21

tx and prognosis for Ramsay Hunt

-82% recover completely in 6mo
-antiviral
-antihistamines/vasodilators
- systemic corticosteroids
-ocular Abs and artificial tears

22

Persistent maxillofacial pain that doesn’t fit any of the more specific pain patterns that is diagnosed by exclusion of other disorders and is hard to localize and may extend to extra-oral area or may be confined to a specific area

Atypical Facial Pain

-male > female
-3-4th decade
-blacks
familial (50x increase risk)

30

unilateral pain of mid and upper face near eye, assoc w/opthalmic division of trigeminal nerve, abrupt onset, no trigger zone, recurs at same time, lasts for weeks then long remission

cluster headache
