To evaluate the success rate of adjustable suture techniques in horizontal eye muscle surgery in children aged 10 years and younger.
A retrospective review of children who had horizontal eye muscle surgery at or before the age of 10 years. Patients were divided into 1 of 2 groups according to whether a nonadjustable or an adjustable technique was used. The preoperative measurements, type of strabismus, and postoperative results were analyzed.
A total of 98 cases in the nonadjustable group and 298 cases in the adjustable group were identified. Early success rate, defined as alignment within 8(Delta) of straight at the end of 3 months, was notably greater in the adjustable group (79%) than in the nonadjustable group (64.5%). The difference was statistically significant (p < 0.01). In the adjustable group, adjustment was performed in 64% of the cases, either because of an undercorrection or overcorrection. The adjustment procedure was performed under topical proparacaine in 20% of cases and under intravenous propofol in 80%. No complications were reported during the adjustment procedure.
The use of adjustable sutures can provide an improved success rate over nonadjustable sutures in eye muscle surgery in children aged 10 years or younger.
评估10岁及以下儿童水平眼肌手术中可调节缝线技术的成功率。
回顾性分析10岁及以下接受水平眼肌手术的儿童。根据是否使用不可调节或可调节技术，将患者分为两组。分析术前测量、斜视类型和术后结果。
不可调节组共98例，可调节组共298例。早期成功率定义为术后3个月末眼位在正位8（棱镜度）以内，可调节组（79%）显著高于不可调节组（64.5%）。差异具有统计学意义（p<0.01）。在可调节组中，64%的病例进行了调整，原因是矫正不足或过度矫正。20%的病例在表面麻醉丙美卡因下进行调整，80%在静脉注射丙泊酚下进行。调整过程中未报告并发症。
在10岁及以下儿童的眼肌手术中，使用可调节缝线比不可调节缝线可提高成功率。
