5. Study Description
Brief Summary
Two percutaneous procedures used in the treatment of idiopathic trigeminal neuralgia are analysed. The effects on pain relief, alterations in cutaneous sensibility and olfactory and salivatory functions are analysed as well.
Detailed Description
Patients diagnosed with idiopathic trigeminal neuralgia, refractory or intolerant to medical treatment, are randomly assigned (after signing a consent form), to receive one of two percutaneous procedures. The patients are evaluated a week before and a week, a month, two months, three months and six months after the surgery.
The questionnaires (Short-Form of the McGill Pain Questionnaire - SF-MPQ, Douleur Neuropathique - DN4, Neuropathic Pain Symptom Inventory - NPSI, Brief Pain Inventory - BPI, Global Clinical Impression - GCI, Hospital Anxiety and Depression - HAD, Brief World Health Organization Quality of Life Questionnaire - WHOQOL-brief, Pain Catastrophizing Scale - PCS) and tests (Quantitative Sensory Testing - QST, olfactory threshold - OT - and discrimination - OD, taste threshold - TT, and salivatory quantification - SQ) are applied as follows:
Pre-op evaluation: SF-MPQ, DN4, BPI, NPSI, HAD, WHOQOL-brief, PCS, QST, OT, OD, TT, SQ.
First visit post-op: SF-MPQ, BPI, NPSI, GCI
Second visit post-op: SF-MPQ, BPI, NPSI, GCI
Third visit post-op: SF-MPQ, BPI, NPSI, GCI
Fourth visit post-op: SF-MPQ, DN4, BPI, NPSI, GCI, WHOQOL-brief, HAD, PCS, QST, OT, TT, SQ.
Fifth visit post-op: SF-MPQ, DN4, BPI, NPSI, GCI, WHOQOL-brief, HAD, PCS, QST, OT, OD, TT, SQ.
Patients with pain recurrence are excluded after the last visit attended. An exploratory analysis is made with 30 patients for a proper sample size calculation during the study.

Procedure
Intervention Name(s)
Balloon Compression Rhizotomy
