“…It is worth noting that the patients in our study did not achieve excellent pain relief immediately after undergoing PRF, but rather required a median interval latency of 3 days (IQR,2-5; range,1-14 ) and two cases needed even more than 10 days to achieve satisfactory results. The interval latency is consistent with our previous studies on PRF for the treatment of supraorbital neuralgia, infraorbital neuralgia, and TN [32][33][34]. We assume the reason for the existence of a recovery period is because PRF could cause plastic changes in pain transmission pathways and result in slow neuromodulation, which would require longer time to take effect.…”

“…Finally, although PRF treatment under the guidance of CT increases the rate of successful punctures and decreases the incidence of complications caused by inaccurate punctures, patients are inevitably exposed to radiation energy which may lead to safety concerns. In recent years, ultrasonography has been proven to be a safer and easier imaging modality, without ionizing radiation [32,42]. Further investigations for the therapeutic efficiency of ultrasound-guided PRF operation on glossopharyngeal nerve is of great importance.…”

Background: Safer and minimal invasive treatment options with minor side effects are in great demand for glossopharyngeal neuralgia (GPN). Pulsed radiofrequency (PRF) is a micro-destructive procedure that could be applied repeatedly without irreversible damage to target tissue. However, few studies have reported the long-term clinical outcomes of PRF in the management of idiopathic GPN patients. Methods: We retrospectively investigated the efficacy and safety of computerTomography (CT)-guided PRF in the treatment of 30 patients with idiopathic GPN in a multi-center clinical study. Numeric rating scale (NRS) score was used to evaluate pain intensity before and after PRF treatment. The effective rate was defined as the percentage of patients with NRS reduction of more than 50%. Baseline characteristics, surgical records, initial pain relief, time to take effect, long-term outcomes, patient satisfaction, the incidence of recurrence as well as subsequent treatment choices, intraoperative and postoperative complications were retrieved from electronic medical records.Results: A total of 30 idiopathic GPN patients who received PRF under CT-guidance were included in our study and the initial effective rate was 93.3%. The cumulative proportion of patients with satisfactory pain relief survival was 93.3% at 12 months, 89.6% at 24 months, 85.3% at 36 months, 79.6% at 48 months, 73.0% at 60 months and 72 months, and 54.8% at 84 months, 108 months as well as 120 months. No serious morbidity or mortality were observed in any of the cases. The median patient satisfaction in Likert scale rating was 4.0 (IQR, 3.0-5.0).Conclusion: According to our results, PRF is an effective and safe therapy for patients with idiopathic GPN. This minimally invasive, micro-destructive, neuro-modulatory technique could be a potential intervention of choice for the treatment of GPN patients who respond poorly to pharmacological treatment.

“…The interval latency is consistent with our previous studies on PRF for the treatment of supraorbital neuralgia, infraorbital neuralgia, and TN. 33 – 35 We assume the reason for the existence of a recovery period is because PRF could cause plastic changes in pain transmission pathways and result in slow neuromodulation, which would require longer time to take effect. Therefore, after receiving PRF procedure, individual variations in posttreatment protocols should be taken into consideration, such as: adjusting oral analgesics to assist patients in getting through the recovery period without progression of pain intensity.…”

Baseline characteristics, surgical records, initial pain relief, time to take effect, long-term outcomes, patient satisfaction using a five-level Likert Scale, the incidence of recurrence as well as subsequent treatment choices, intraoperative and postoperative complications were retrieved from electronic medical records. Results: A total of 30 idiopathic GPN patients who received PRF under CT-guidance were included in our study and the initial effective rate was 93.3%.

“…We have reported the efficacy of PRF for treating idiopathic supraorbital neuralgia and refractory infraorbital neuralgia in recent years. [15][16][17] A small number of patients developed numbness in the area innervated by the target nerve and recovered soon after the onset of numbness. In the present study, trifling numbness along the maxillary nerve was observed in 6 patients.…”

Objective To further evaluate the efficacy and safety of computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency treatment for patients with refractory episodic and chronic cluster headache (CH). Methods Forty‐five patients with refractory episodic CH and 14 patients with chronic CH who underwent computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency between January 2011 and December 2018 at the Beijing Tiantan Hospital were included and analyzed in this retrospective cohort study. Results A total of 59 patients underwent 106 computerized tomography–guided pulsed radiofrequency procedures throughout the observational period. Effective remission was observed in 95.6% and 64.3% of patients with refractory episodic and chronic CH, respectively. Repeated computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency procedures for recurrent CH was also proven to be effective. No severe side effects or complications were observed in this study. Conclusion The computerized tomography–guided sphenopalatine ganglion–targeted pulsed radiofrequency procedure is an effective, safe, and repeatedly effective strategy for refractory CH. For patients who have not responded to conservative treatment, this minimally invasive intervention is a reliable alternative.
