The aim of this study was to evaluate the incidence, clinical features, and risk factors of sustaining inferior rectus (IR) palsy in a group of pediatric patients with orbital floor blowout fractures. We performed a retrospective case review of sequential cases of pediatric orbital floor blowout fractures (<18 years old) from 2000 to 2013 in a tertiary ophthalmic center in Singapore. A total of 48 patients were included in our study, of whom 5 had IR palsy (10.4%). Patients with IR palsy had a higher mean age (16.4 ± 1.5 years) compared with patients without IR palsy (12.4 ±3.3 years), had significantly ( < 0.05) worse preoperative motility, and had significantly greater proportion developing postoperative hypertropia (100%) compared with patients without IR palsy (4.7%). Our series of pediatric blowout fractures demonstrated IR palsy prevalence and clinical features for IR palsy which may be distinct to the pediatric group.
本研究的目的是评估一组小儿眶底爆裂骨折患者发生下直肌（IR）麻痹的发生率、临床特征和危险因素。我们对2000年至2013年新加坡一家三级眼科中心连续收治的小儿眶底爆裂骨折（<18岁）病例进行了回顾性病例分析。我们的研究共纳入48例患者，其中5例发生IR麻痹（10.4%）。与未发生IR麻痹的患者（12.4±3.3岁）相比，发生IR麻痹的患者平均年龄更大（16.4±1.5岁），术前眼球运动明显更差（P<0.05），且术后发生上睑下垂的比例显著更高（100%），而未发生IR麻痹的患者这一比例为4.7%。我们的小儿爆裂骨折系列研究显示了IR麻痹的患病率和临床特征，这些特征可能在小儿群体中具有独特性。
