RESUMO
Objective To investigate clinical efficacy about treatment of trigeminal neuralgia using botulinum toxin of type A and ultrashort wave.Methods 40 patients with trigeminal neuralgia were randomly divided into the control group(n =20)and the treatment group(n =20)according to digital table method,patients in the control group were injected with lidocaine,triamcinolone acetonide and vitamins B12 injection in pain -sensitive point,the treatment group were injected botulinum toxin of type A 50 -150 u in pain -sensitive point.The two groups were in the ultrashort wave therapy.Used VAS pain scores to evaluate local pain about two groups of patients before treatment,one week after treatment,one month after treatment,three months after treatment,the clinical efficacy after treatment at different time points were compared between the two groups.The two groups of patients showed sleep improvement,the sleep status of patients were observed.Results The VAS score in the control group 1 week after treatment was (3.78 ± 1.35)poinrs,and was (7.03 ±1.07)poinrs before treatment,the difference was statistically significant(t =-3.39, P 0.05). After treatment for 1 week,the scores of VAS in the treatment group was (5.18 ±1.03)poinrs,which was decreased compared with that before[(7.63 ±1.04)poinrs],the difference was statistically significant(t =4.23,P 0.05).After the treatment for 1 month and 3 months,VAS score differences were statistically signifi-cant(t =7.56,11.61,all P <0.05).In the control group,after treatment for 1 week,1 month and 3 months showed significant efficiency of 77.5%,33.3% and 11.1% respectively,which showed a downward trend.In the treatment group,after treatment for 1 week,1 month and 3 months,the efficiency were 57.7%,69.2% and 80.7%,which was a rising trend.And the efficiency was significantly higher than that of the control group,the differences were statistically significant(χ2 =5.16,17.99,P <0.05).Conclusion The treatment of trigeminal neuralgia using botulinum toxin of type A with ultrashort wave can significantly reduce pain in patients,the effect is better than lidocaine,triamcinolone acetonide and vitamin B12 .
