Clinical study of upper cervical nerve block combined with injection of ozone for the treatment of cervicogenic headache
Abstract：Objective To study the effect of the upper cervical nerve block combined with injection of ozone for the treatment of cervicogenic headache.Methods Sixty patients suffering from cervicogenic headache were randomly divided into group A(n =31)and group B(n =29).Group A received C2,3 nerve block combined with injection of ozone;group B received upper cervical nerve block.The efficacy and improvement of pain were compared.Results For group A,at 1 week,1 month and 3 months after opeartaion,the visual analogue scale(VAS) scores were (1.3 ± 0.4),(1.8 ± 1.2) and (3.1 ± 1.4) scores ; the excellent and good rate was 100.0％ (31/31),87.1％ (27/31),80.6％ (25/31) respectively.For group B,the VAS scores were (1.5 ± 1.1),(3.4 ± 1.3) and (4.3 ± 2.2) scores ; the excellent and good rate was 100.0％ (29/29),72.4％ (21/29),62.1％ (18/29),respectively.Compared with group B,3 months and 6 months after treatment,the VAS in group A were significantly reduced,the excellent and good rate were higher (P ＜ 0.05).Conclusion Upper cervical nerve block combined with injection of ozone in treatment of cervicogenic headache is better than the upper cervical nerve block alone,but its long-term effect remains to be explored.
