Abstract:

【Abstract】 Objective To observe the short-term effect of injection of botulinum toxin type A (BTX-A) in neck muscles for treatment in residual torticollis after strabismus surgery. Design Retrospective case series. Participants The 21 children with residual torticollis more than 3 months after superior oblique incomplete paralysis surgery. Methods BTX-A injections in neck muscles were performed in 21cases with residual torticollis after strabismus surgery. Before the injection, target muscles were fixed by surface markers. Injection dose is with 4-8 U/kg and administrated at 2-8 points. Head position was measured with head position measuring instrument. And the parents’ feelings about these children’ head position were recorded too. Follow up time is 3-6 months. Main Outcome Measures Measured head position and parents’ assessment of these children’ head position. Results 3 month after BTX-A injection, mild amelioration of torticollis were presented in 38.1% of children, and significant amelioration was 9.5%. According to parents’ assessment, 57.1% children had mild amelioration and 9.5% had significant amelioration. Conclusions Short-term observation suggests injection of BTX-A in neck muscles has a limited effect in treatment of residual torticollis. (Ophthalmol CHN, 2015, 24: 258-262)
