Comparison of Ganglion Impar Radiofrequency Ablation and Phenol Neurolysis Techniques for Chronic Coccydynia Treatment
Source: ClinicalTrials.gov · Last updated 17 Jun 2025 · Not updated for over 12 months - ask the site whether it is still open
Brief summary (registry, in English)
Radiofrequency ablation and phenol neurolysis of the ganglion impar are methods used in cases unresponsive to medication, particularly in patients who derive short-term or partial relief from the initial ganglion impar block. In clinical practice, clinicians frequently use these two injections in patients with treatment-resistant pain who only partially benefit from the initial blockade procedure. To date, the medical literature lacks a comprehensive study comparing the efficacy of radiofrequency ablation and phenol neurolysis in patients who partially benefit from ganglion impar block. Therefore, this study is designed to compare the effectiveness of these two methods in patients with chronic coccydynia.
