9. Compression of blood vessels, especially the superior cerebellar
artery occurs
Chronic irritation of trigeminal nerve at the root entry zone
Increased firing of the afferent or sensory fibres
Trigeminal neuralgia

13. nerve Involvement :
maxillary-60%
mandibular-49%
ophthalmic-16%
all 3 divisions-1%
Right side > left side
1.7 : 1

14. Unilateral pain
Early pain or
pretrigeminal neuralgia
:-dull,aching,burning.
Pain lasts for few seconds
to a minute.
Aggravates and sufferer
have attempted suicide.

20. Diagnosis based on clinical history, supplemented
by physical examination findings and cranial
imaging studies.
Detailed intraoral examination to rule out
odontogenic and non odontogenic source for the
pain
Examination of CNV,VII &VIII
Symptomatic TN from a CPA mass often shows
facial weakness and hearing loss on that side

22. Diagnostic brain imaging to visualize anatomic
landmarks around trigeminal ganglion and
CPA
CT, MRI – to rule out CPA lesions and to
visualize subtle vascular anomalies causing
compression

24. Trigeminal neuralgia is usually treated with drugs called
anti- convulsants which include:
 Carbamazepine (drug of choice) (400-1000mg/day)
 Phenytoin (300mg/day)
 Oxycarbazepine
 Gabapentin (600-1200mg/day)
 Baclofen, lamotrigine, clonazepam

25.  Surgical options include:
1. Peripheral
• Cryotherapy
• Neurectomy
• Alcohol injections
2. Gasserian ganglion
• Radiofrequency, thermocoagulation
• Glycerol injection
• Microcompression (balloon compression)
3. Posterior fossa
• Neurovascular decompression
• Stereotactic radiosurgery

26.  Trancutaneus electric nerve stimulation
 Laser
 Rhizotomy
 Alcohol injections

28. :
1. Apply ice packs. Cold often numbs the area and
will reduce the pain
2.Get adequate rest in normal rest cycles
3.Manage your stress well and keep stress levels
low
4. Avoid foods that may act as nerve stimulants,
such as coffee, tea, and foods that are high in
sugar
5. Maintain adequate hydration and electrolyte
levels
6. Practice healthy living principles such as diet
and exercise
