目的 探讨水平肌加强减弱术联合下斜肌切断减弱术治疗小儿斜视的临床疗效.方法 选取我院2013年1月至2014年1月间收治的斜视伴下斜肌功能亢进的80例患儿作为研究对象,随机将其分为研究组和对照组,每组各40例.对照组患儿单纯采用水平肌加强减弱术进行治疗,研究组采用水平肌加强减弱术联合下斜肌切断减弱术进行治疗.观察两组患儿的临床疗效.结果 经治疗后,研究组患儿斜视症状治疗的有效率为97.5%,明显高于对照组患儿斜视症状治疗的有效率87.5%(P<0.05) 差异均有统计学意义;研究组患儿下斜肌功能治疗的有效率为87.5%,明显高于对照组患儿下斜肌功能治疗的有效率72.5%,(P<0.05) 差异均有统计学意义.结论 水平肌加强减弱术联合下斜肌切断减弱术治疗小儿斜视具有良好的临床疗效,值得在临床上进一步推广.%Objective To evaluate the effects of horizontal muscle strengthening/weakening combined inferior oblique cutting/weakening on strabismus in children.Methods 80 strabismic patients with hyper-functioning inferior oblique were enrolled from out hospital between January 2013 and 2014.Patients received either horizontal muscle strengthening/weakening alone (n=40), or combined with inferior oblique weakening (n=40).Results The efficacy of the surgery was 97.5% in children received combined surgeries.This rate is significantly higher than that in children received horizontal correction only (87.5%;P<0.05).Inferior oblique function returned to normal in 87.5% of the children who received combined surgeries, significantly higher than that in control group (72.5%;P<0.05).Conclusions Inferior oblique weakening combined with horizontal muscle correction is effective in treating strabismus in children.
