Study Arms (2)

Balloon Compression Rhizotomy

ACTIVE COMPARATOR

Patients that are submitted to Balloon Compression Rhizotomy

Procedure: Balloon Compression Rhizotomy

Radiofrequency Thermal Coagulation Rhizotomy

ACTIVE COMPARATOR

Patients that are submitted to Radiofrequency Thermal Coagulation Rhizotomy

Procedure: Radiofrequency Thermal Coagulation Rhizotomy

Interventions

The balloon compression rhizotomy is performed in a percutaneous fashion where a Fogarty catheter is positioned in the gasserian ganglion and inflated with 0,7 milliliters of radiopaque dye during 120 seconds.

Balloon Compression Rhizotomy

The gasserian ganglion is submitted to a controlled thermal coagulation with a electrode with 80 Celsius degrees of temperature during 60 seconds on the specific division.

Radiofrequency Thermal Coagulation Rhizotomy
