  • 2-4% (young pt d/t MS)
112
Q

Postherpetic neuralgia (PHN)

A

nerve pain (neuralgia) that persists after shingles rash has cleared. If pain goes, but then returns at a later date, this too is called PHN.

Shingles is an infection of a nerve, and causes a typical rash. It is caused by the varicella-zoster virus.

  • UP 60yrs

  • more WOMEN
  • r/t some Sx dental procedures (damage to nerve)
  • attacks, remissions
113

114
Q

Postherpetic neuralgia (PHN): Triggers

A
  • touching face
  • chewing
  • shaving
  • speaking
  • brushing teeth
  • drinking hot/cold
  • trigger point areas along nerve
  • pain lasts sec - minutes
115

Q

Trigeminal Nerve Innervation (see pic of head w dermatomes)

A

1 - Ophthalmic Branch
2 - Maxillary
3 - Mandibular

117
Q

Trigeminal Neuralgia (tic douloureux): Dx

A
  • no specific test
  • neuro asst
  • pain Hx
  • MRI (to rule out MS or tumor)
118
Q

Trigeminal Neuralgia (tic douloureux): Sx

A

-Micro-vascular Decompression (removing or relocating BV in contact w trigem nerve)

-Gamma Knife Radiosurgery:
.surgeon directs focused dose of radiation to root of trigem nerve
.using radiation to damage nerve
.relief is gradual, may take several wks
.works in majority of pt
.can be repeated
.considered Safe
119
Q

Trigeminal Neuralgia (tic douloureux): MM

A
  • microvascular decompression
  • anticonvulsants
  • antispasmodics
  • Rhizotomy (alchohol or glycerol inj)
120
Q

Trigem Neur: Rhizotomy

A

-neurosurgical procedure that selectively destroys problematic nerve roots in the spinal cord

GLYCEROL INJ:
-needle through face to base of skull
-needle guided through
Post PO: numbness/tinging

ALCOHOL INJ:
-may need repeated injs

BALLOON COMPRESSION:

  • needle through face
  • baloon at end of catheter
  • inflate at right spot to supply pressure to trig nerve to damage it and block pn signals

SEVER NERVE COMPLETELY:
incision behind ear
Risk, perm numbness in face. instead of cutting, surgeon may decide to traumatize nerve instead (rubbing)

121
Q

Trigem Neur: Radiofrequency Thermal Lesioning

A
  • destroy nerve fibers asociated w pain
  • while dedated, insert hollow needle thru face to base of skull to trig nerve
  • when needle in position, awaken pt.
  • dr sends electrode thru needle and send current through
  • pt lets dr know when and where they feel tingling
122
Q

Trigem Neur: AntiConvulsants

A
  • **most common
  • also used to treat behavioral probs
  • MED: Tegretol, Carbatrol (Carbamazepine)

Q

Trigem Neur: Comfort Measures

A
  • avoid touching face
