16 -carbamazepine(stronger evidence) or oxcarbazepine(better tolerability) should be offered as first-line treatment for pain control -for patients with TN refractory to medical therapy early surgical therapy may be considered. Gasserian ganglion percutaneous techniques, gamma knife and microvascular decompression may be considered. -microvasculardecompression may be considered over other surgical techniques to provide the longest duration of pain freedom -the role of surgery versus pharmacotherapy in the management of TN in patients with multiple sclerosis remains uncertain

17 complications of surgery PGL: percutaneousgasserianlesions (includes radiofrequency thermocoagulation, glycerol rhizotomy, balloon compression) MVD: microvascular decompression GKS: gamma knife surgery.Anoxic brain injury stories


18 percutane interventies voor TN (1) microvascular decompression is considered the gold standard percutaneous techniques remain an effective option for some patients most common procedures: balloon compression (BC), glycerol rhizotomy (GR), and radiofrequency thermocoagulation (RF) no randomized clinical trial exists comparing the efficacy and long-term outcomes of these procedures atypical symptoms are negative predictor of long-term efficacy across all treatments patients with MS have higher recurrence rates and require more treatments

19 percutane interventies voor TN (2) BC selectively injures larger pain fibers while sparing small fibers (useful in va pain: sparing of the corneal reflex) does not require an awake, cooperative patient more often trigeminal depressor response (hypotension, bradycardia) pain relief inup to 91% at 6 months and 66% at 3 years patients unable to tolerate general anesthesia or those with significant cardiac histories are generally poor candidates dysesthesia in10% to 20%, severe numbness in 20% masseter weakness typically resolves within 12 months

20 percutane interventies voor TN (3) RF T monitoring, short-acting anesthetic agents and electric stimulation with awake-patient feedback is needed to minimize side effects somatotopic nerve mapping and selective division lesioning pain relief in up to 97% initially and 58% at 5 years multiple treatments improve outcomes but carry significant morbidity risk masticatory weakness up to 29%, dysesthesia average3.7%, corneal numbness average 9.6%

21 percutane interventies voor TN (4) GR does not require an awake patient trigeminal depressor response in up to 20% contrast cisternogram and injection of glycerol in sitting position after injection patient remains sitting for 2 h to prevent leakage into the posterior fossa pain relief in up to 90% at 6 months and 54% at 3 years pain relief correlates with degree of numbness dysesthesias in 8.3%, corneal numbness in 8.1%, masseter weakness in 3.1%
