ABSTRACT

Objective:To discuss the clinical results of treatment for congenital muscular torticollis with different injection points of botulinum toxin type A and traditional conservative method, and to expound the safety and effectiveness of this way.Methods:From January 2018 to December 2018, 60 cases aged from one month to six months with congenital muscular torticollis who visited the outpatient clinic of plastic surgery in Children＇s Hospital of Quanzhou, a teaching hospital of FuJian Medical University, and there were 38 males and 22 females. The treatment groups were divided into two groups according to random number method that were treated with botulinum toxin type A: the single point group was given one point injection, and the three-point group was injected with three points, while the control group was treated with traditional conservative treatment (mainly manual stretching exercises). The number of cases in each group was 20.Results:The differences of muscle thickness and muscle length were repeatedly measured at different time points in the same group and variance analysis conducted. The results showed that there were statistical significances among the two indicators at different time points in each group ( P<0.05). Least significant difference (LSD) was further adopted for pairwise comparison between indicators at different time points in each group and the differences were statistically significant ( P<0.05). In the comparison of treatment effect of different groups after twelve months follow-up, the cure rate was 85% (17 cases) in the single point group, 95 % (19 cases) in the three-point group, and 80 % (16 cases) in the control group, there was no significant difference among three groups ( P>0.05). Conclusions:Local injection of botulinum toxin type A is a safe and effective treatment option for congenital muscular torticollis, which can achieve the same clinical effect as traditional conservative treatment.
