Evaluation of the Results of Ganglion Impar Blockade in Patients with Chronic Coccydynia

Our study examined whether bupivacaine and steroid injections followed by Radiofrequency Thermocoagulation (RFT) improved symptoms among coccydynia patients. The Ganglion Impar Block (GIB) treatment of eight patients with coccydynia in our neurosurgery clinic was reviewed. A retrospective analysis of demographics, pain causes, X-ray results, types of invasive procedures, and Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores was performed. VAS and ODI scores were recorded before the procedure, the first day after the procedure, and three months after the procedure. The study included five females (62.5%) and three males (27.5%). The mean age of the patients was 4 0.5 ± 10.6 years, and the mean BMI was 26.21 ± 4.2 kg/m². Two patients had idiopathic neuralgia, two had trauma -related neuralgia, two had post-herpetic neuralgia, and one patient had persistent pain following previous anorectal surgery and S2 perineural c ystrelated pain. There was a significant improvement in both VAS [2.5 (range: 1 -4)] and ODI scores [4 (range: 0-34)] on the first day after the procedure (p<0.001). These low scores were maintained at the third month [VAS: 1.5 (range: 1 -10) and ODI: 1 (range: 0-78)]. In only one patient, excision of the coccyx was planned due to inadequate pain relief. In patients with coccydynia, bupivacaine and steroid injections followed by RFT provide satisfactory long -term analgesia, as evidenced by decreased VAS and ODI scores.
