Background:
Trigeminal neuralgia is the most common cause of facial pain but can be challenging to treat. Some patients fail on medications, and while surgical procedures achieve short-term efficacy, they can be associated with numerous complications. We present a case series suggesting the efficacy and safety of using pulsed radiofrequency (PRF) through the transcoronoid approach to treat trigeminal neuralgia.
Methods:
This retrospective analysis included 8 cases with data collected from the electronic medical record. Outcomes were pain scores before and after the procedure as well as the percent improvement after the procedure (improvement in severity, frequency, and duration).
Results:
Patients had an average age of 56.4 ± 13 years. All patients reported improvement after the procedure, and 3 patients reported that their improvement was ongoing at the time of follow-up. No complications were reported by any of our patients.
Conclusion:
PRF through the transcoronoid approach may be a safe and effective approach for treating trigeminal neuralgia in patients resistant to conservative management.
