Randomized Controlled Trial Comparative Study
Anatomoradiological landmarks for accuracy of radiofrequency thermorhizotomy in the treatment of trigeminal neuralgia.
The correct positioning of the electrode is of prime importance for effectiveness and selectivity of percutaneous trigeminal radiofrequency thermorhizotomy (RF-TR) for the treatment of trigeminal neuralgia (TN). The aim of our study was to establish some anatomoradiological landmarks for the purpose of accurate placement of the electrode tip in RF-TR. ⋯ Our data suggest that the determination of the presented landmarks allows customization to individual patient anatomy and may help the surgeon achieve a more selective effect with a variety of percutaneous procedures for each branch of the trigeminal root.
