A multiarray mapping method to minimize morbidity from thermocoagulation as treatment of refractory trigeminal neuralgia.

Background: Conventional percutaneous thermocoagulation of postgasserian fibers has shown high success rates, with significant residual morbidity.

Methods: This communication summarizes conclusions of multiple publications on our computerized mapping method and technique, and presents new data on short- and long-term results on trigeminal pain, including an actuarial analysis, complications.

Results: In TTN, 97.

Reducing unnecessary morbidity from percutaneous thermocoagulation in the treatment of trigeminal neuralgia--part C: a starting point for a somatotopic map of the human Gasserian ganglion.

Objectives: An original method and technique has been designed to reduce the significant morbidity associated with techniques currently used for percutaneous thermocoagulation in the treatment of trigeminal neuralgia. The current report deals with the mathematical and biostatistical analysis of verbal responses gathered using such a method in an attempt, as a starting point, to establish the somatotopic organization of the human gasserian ganglion.

Method: A correspondence analysis was used to validate verbal responses.

Reducing unnecessary morbidity from percutaneous thermocoagulation in the treatment of trigeminal neuralgia. Part B: a computerized protocol for quantitative analysis of data for radiofrequency thermocoagulation with the quadripolar electrode method and technique.

Objectives: An original method and technique was designed to reduce the still significant morbidity of percutaneous thermocoagulation in the treatment of trigeminal neuralgia. A critical part of this technique is the computerized analysis of data, which is the subject of this report.

Method: We fully describe the computerized program for data collection and analysis, which is designed to evaluate addressed and unaddressed aspects of trigeminal neuralgia using the quadripolar electrode method and technique.
