A型肉毒毒素治疗痉挛性斜颈的临床研究

目的 观察A型肉毒毒素(BTX-A)治疗痉挛性斜颈的效果.方法 对64例痉挛性斜颈患者在颈部肌肉多点注射BTX-A,分析评价其疗效.结果 痉挛性斜颈患者经BTX-A治疗后症状明显改善,BTX-A用量(120.37±25.26)U;注射点数(30.00±4.85)个;Tsui评分治疗前为(13.08±4.16)分,治疗后2周为(4.21±2.63)分,差异有统计学意义(P<0.01).完全缓解16例(25.0%),明显改善39例(60.9%),部分改善8例(12.5%),无效1例(1.6%),有效率85.9%(55/64);疗效维持时间为(16.86±4.57)周;重复治疗者复发症状减轻,治疗剂量下降,疗效仍良好.所有患者均未见严重不良反应.结论 BTX-A治疗痉挛性斜颈是一种安全有效、简便易行的治疗手段,可作为治疗痉挛性斜颈的首选药物.

Clinical study of botulinum toxin type A in the treatment of spasmodic torticollis

Objective To evaluate the therapeutic effect of botulinum toxin type A(BTX-A)injection in the treatment of spasmodic torticollis.Methods Sixty-four patients with spasmodic torticollis underwent the treatment of intramuscular injection of BTX-A in neck muscles.As a result,the efficiency of BTX-A therapy could be evaluated successfully.Results Considerable improvement of symptoms for the spasmodic torticollis patients was observed with BTX-A treatment.The average dose of BTX-A was(120.37 ±25.26) U.Injection points were 30.00 ± 4.85.The Tsui scores before treatment were (13.08 ±4.16) scores,and 2 weeks after treatment were (4.21 ± 2.63) scores.The Tsui scores showed a significant reduction after BTX-A injections (P <0.01).After treatment complete remission rate was 25.0% (16/64),significant improvement rate was 60.9% (39/64),partial improvement rate was 12.5% (8/64),invalid rate was 1.6%(1/64) and efficient rate was 85.9% (55/64).Duration of effect was (16.86-4.57) weeks.Patients who received repeated injections also had good response,with symptoms improved and dosage of BTX-A reduced.No serious adverse events happened in treatments.Conclusion BTX-A therapy is simple and effective in the treatment of spasmodic torticollis and should be considered as the first-choice treatment for the condition.
