RESUMEN
Objective:To investigate the efficacy of radiofrequency ablation combined with ozone therapy under CT guidance in the treatment of lumbar disc herniation.Methods:A total of 93 patients with lumbar disc herniation who were admitted to The First Hospital of Jiaxing from January 2019 to May 2022 were included in this study. They were randomly divided into an observation group ( n = 47) and a control group ( n = 46). The control group was treated with radiofrequency ablation and the observation group was treated with radiofrequency ablation combined with ozone therapy. Efficacy was compared between the two groups at 3 months after surgery. The pain was compared between the two groups before and 7 days and 3 months after surgery. Inflammatory factors were compared between the two groups before and 7 days after surgery. The lumbar spine function was compared between the two groups before and 3 months after surgery. Results:At 3 months after surgery, the excellent and good rate in the observation group was significantly higher than that in the control group [89.36% (42/47) vs. 71.74% (33/47), χ2 = 4.63, P < 0.05). At 7 days and 3 months after surgery, Visual Analogue Scale scores in the observation group were (2.91 ± 0.54) points and (1.32 ± 0.31) points, respectively, which were significantly lower than (3.76 ± 0.62) points and (2.08 ± 0.47) points in the control group ( t = 7.06, 9.22, both P < 0.001). At 7 days after surgery, serum interleukin-1β, interleukin-6, and tumor necrosis factor-α in the observation group were (0.24 ± 0.05) μg/L, (18.49 ± 3.47) ng/L, and (97.94 ± 17.43) ng/L, respectively, which were significantly lower than (0.37 ± 0.09) μg/L, (24.31 ± 4.12) ng/L, and (148.87 ± 20.13) ng/L, respectively in the control group ( t = 8.63, 7.37, 13.05, all P < 0.05). At 3 months after surgery, the Japanese Orthopedic Association score in the observation group was significantly higher than that in the control group [(25.68 ± 2.28) points vs. (21.17 ± 3.24) points, t = -7.78, P < 0.001], and the Oswestry Disability Index in the observation group was significantly lower than that in the control group [(9.84 ± 1.43) points vs. (13.46 ± 2.18) points, t = 9.49, P < 0.001]. Conclusion:Radiofrequency ablation combined with ozone therapy under CT guidance is highly effective on lumbar disc herniation. The combined therapy can reduce pain and inflammatory reactions in patients and improve lumbar function.
RESUMEN
Objective To observe the clinical effect of CT-guided percutaneous puncture of stylomastoid foramen and radiofrequency ablation on primary hemifacial spasm. Methods Twenty-seven patients with primary hemifacial spasm, admitted to and accepted CT-guided percutaneous puncture of stylomastoid foramen and radiofrequency ablation in our hospital from August 2018 to May 2019, were chosen in our study. Clinical data and efficacy of the patients were retrospectively analyzed. Results All patients were punctured to the stylomastoid foramen precisely under the guidance of CT localization; 21 could detect facial muscle twitch with 0.1-0.5 mA current, and positive results were also found in 6 patients with 0.5 mA current after adjusting the position of the needle tip. After standard radio frequency ablation (mean 83.3 ℃ for 23.7 seconds), 26 patients had complete disappearance of facial spasm, but left grade II (n=18) or grade III (n=8) facial paralysis; one patient with disappearance of abnormal electromyographic response waveform as the end criterion only partially relieved, but no facial paralysis. No facial hematoma, intracranial hemorrhage, infection, or death occurred. Follow-up for 2-12 months showed no recurrence or aggravation of facial paralysis. Conclusion CT-guided percutaneous puncture of stylomastoid foramen by radio frequency ablation can effectively treat primary hemifacial spasm, but there will be mild facial paralysis.
