Masseter Muscle Thickness in Gasser Ganglion Radiofrequency Treatment
Condition(s) studied
Investigational drug(s) / intervention(s)
Gasserian Ganglion Radiofrequency Thermocoagulation: Gasserian ganglion radiofrequency thermocoagulation is performed in the operating room under fluoroscopy. In sterile condition, the foramen ovale is shown by the pain management specialist under fluoroscopy guidance. After this condition, the entry of the needle is marked and anaesthetised with local anaesthetic. After the entry of the gasserian ganglion with the radiofrequency needle, 10 cm long, the location is checked with sensory and motor stimulation. If the placement is correct, 70 degrees 70 seconds of radiofrequency thermocoagulation is applied.
Study summary
Trigeminal neuralgia is common painful disorder in pain medicine clinics. Gasserian ganglion radiofrequency thermocoagulation is one of the treatment option in patients with trigeminal neuralgia in refractory cases. The most commonly involved branch in trigeminal neuralgia is the mandibular branch. Masseter muscle is innervated by mandibulary nerve branch of the trigeminal nerve.
The radiofrequency thermocoagulation therapy is used to ablate the affected trigeminal nerve branch and some of patients complain of subjective masseter weakness after this procedure.
In theoretical basis, muscles innervated by target nerve are affected from ablation procedure. In this study the primary aim is to evaluate the change of the masseter muscle thickness in patients treated by gasserian ganglion radiofrequency thermocoagulation. The results may also show possible functional effect of the procedure related with masseter muscle.
Eligibility
Primary outcome measure(s)
- Masseter muscle thickness — Pre-procedural time
The thickness of the masseter muscle will be measured and recorded by ultrasound while bilaterally contracted and relaxed. - Masseter muscle thickness — Post-procedural first month
The thickness of the masseter muscle will be measured and recorded by ultrasound while bilaterally contracted and relaxed. - Masseter muscle thickness — Post-procedural third month
The thickness of the masseter muscle will be measured and recorded by ultrasound while bilaterally contracted and relaxed.
