摘要
背景 儿童眼眶骨折有其自身的特点,选择合适的整复材料是提高手术成功率的有效措施.可吸收板材料的出现为儿童眼眶骨折的修复提供了一种新的、无需二次手术取出的填充物,但其与常规填充物的疗效和安全性比较研究较少见. 目的 比较可吸收板材料与Medpor材料在儿童眼眶骨折整复手术中的效果及安全性. 方法 对2008年4月至2014年8月在北京同仁医院手术治疗的儿童眼眶骨折72例72眼的临床资料进行回顾性分析,其中包括可吸收板植入物治疗者28眼及Medpor植入物治疗者44眼,2个组术前人口基线特征及临床症状匹配,2个组除植入物不同外,手术过程相同,并均于术后2d即开始眼肌功能性训练.CT检查评价术眼手术前后眶壁的影像学表现,平均随访12.7个月,比较2个组术后术眼的疗效,包括眼眶骨折的解剖学复位率、眼球运动和复视的改善率,评估2种手术的安全性和并发症,包括眼球内陷、眶下神经支配区麻木率及术后感染的发生率. 结果 所有术眼术后复视、眼球运动障碍等症状改善或消失,其中可吸收板植入物组症状改善者占92.9％（26/28）,Medpor植入物组占90.9％（40/44）,差异无统计学意义（P=0.57）.术后可吸收板植入物组眶下神经支配区麻木者13眼,占46.4％,Medpor植入物组20眼,占45.5％,组间差异无统计学意义（P=0.56）.CT检查结果显示,2个组术眼术后眶壁缺损区修复,眶内嵌顿的软组织回复,眶壁植入物在位.可吸收板植入物组未发现术后残存眼球内陷者及术后感染者,但Medpor植入物组眼球内陷及迟发感染者各1例,均占2.27％.结论 可吸收板材料与Medpor材料均可用于儿童眼眶骨折的整复,手术效果接近,可吸收板材料用于儿童眼眶骨折的修复并发症少.
Background Orbital fracture in children has its own characteristics.Choosing the suitable plastic materials is the effective measurement to improve the successful rate of surgery.Absorbable plate filling provides a new material for children with orbital fracture.However,few studies compare the effectivity and safety between absorbable plate filling and conventional filling.Objective The aim of this study was to compare the longterm efficacy and safety between absorbable plate and Medpor implants in the repair of pediatric orbital fracture.Methods Clinical data of 72 eyes of 72 pediatric patients with orbital fracture who received surgicals reconstruction in Beijing Tongren Eye Center from 2008 April to 2014 August were respectively analyzed,including 28 patients with absorbable plates filling and 44 patients with Medpor implants.Demography and preoperative clinical signs were matched between the two groups.Operative procedure was same except the implanted materials.The functional training of extraocular muscle was performed since the second day after surgery in both groups.The imaging findings of the orbit were evaluated by computed tomography （CT） before and after surgery.The patients were followed-up for avarage 12.7 months after operation.The therapeutic effectiveness and safety were compared between the different implants,such as incidence of enophthalmos,extraocular movement impairment and diplopia,and the sensory deficit of skin and complications were documented.Results Extraocular muscle movement improved and diplopia alleviated or disappeared in 92.9% （26/28） in the absorbable plate group and 90.9% （40/44） in the Medporgroup,without significant difference between the two groups （P=0.57）.The sensory deficit of skin was found in 13 eyes （46.4%） and 20 eyes （45.5% in the absorbable plate group and Medpor group,respectively,and there was no significant difference between the two groups （P =0.56）.CT revealed that the anatomical reconstruction of orbits could be achieved in all patients in both groups without the shifting of implants and extrusion.No enophthalmos and postoperative infection were found in absorbable plate group,however,the residual enophthalmos or late infection was found in I eye for each in the Medpor group.Conclusions Both the absorbable plate and Medpor implants show good results for reconstruction of pediatric orbital fracture.Absorbable plate is an ideal material for pediatric orbital blowout fracture because of fewer postoperative complications.
