Background Herpes zoster neuralgia has a considerable impact on people’s quality of life, especially after the development of postherpetic neuralgia. There are many clinical reports on the treatment of herpes zoster neuralgia, but there have been no special reports on the treatment of herpes zoster involving the neck. Our research focuses on a posterior and upper quarter of the cervical foramina puncture approach for herpes zoster involving the cervical 3–8 (C3-8) nerve region and to consider the safety and efficacy of pulsed radiofrequency combined with steroid injection and ozone injection in this puncture path under CT guidance. Materials and Methods A total of 104 patients with herpes zoster neuralgia involved in the cervical 3–8 nerve region use a posterior and upper quarter of the cervical foramina puncture approach received pulsed radiofrequency combined with steroid and ozone injection to the dorsal root ganglion. The total number of injection procedures, complications, NRS collection (preprocedure, postprocedure at once, two, four and 12 weeks) and drug dose decreases were documented. Results During a total of 257 procedures, 254 procedures successfully completed PRF (3 cases failed to reach the C8 aim points), and the rate of puncture failure was 1.17%. Drug injection was successfully performed in 252 procedures (the injection success rate was 99.21%); the NRSs (preprocedure, postprocedure at once, two, four and twelve weeks) were 5.75 ± 0.682, 2.6 ± 1.023, 2.21 ± 0.925, 1.89 ± 1.162, and 1.43 ± 1.369, and the difference among them was statistically significant. Drug dosages decreased before and after operation and showed statistically significant differences. Conclusion Pulsed radiofrequency combined with steroid and ozone injection for herpes zoster neuralgia involving the C3-8 nerves under CT guidance through a posterior superior quarter approach showed safety and efficacy and had a high success rate, and the NRS decreased significantly.
