Ultrasound-aided fixation of a biodegradable cranial fixation system called SonicWeld Rx, has been widely applied in the fields of craniofacial surgery and plastic surgery. However, there are few reports that denote its use in the field of neurosurgery. This study aimed to evaluate the usefulness of SonicWeld Rx system in pediatric neurosurgery.
This study included 11 pediatric patients(10 boys, 1 girl), who underwent craniotomy for moyamoya disease, brain tumor, and arachnoid cyst. Their mean age was 6.4 years, ranging from 4 to 10 years. LactoSorb system was applied in 6 patients and SonicWeld Rx system in 5.
The time required for screw fixation was significantly shorter in the SonicWeld group(6.5±1.4sec)than in the LactoSorb group(13.4±2.8sec), with p<0.05. The quality of fixation strength was adequate in both groups. There were no perioperative complications related to the absorbable fixation device. A 3-D skull CT detected no malposition of the bone flap 3 months postoperatively. There were no scalp complications noted for an average of 21 months.
SonicWeld Rx system can be easy and useful in fixing the bone flap to the cranium in the field of pediatric neurosurgery.
一种名为SonicWeld Rx的可生物降解颅骨固定系统的超声辅助固定已在颅面外科和整形外科领域广泛应用。然而，鲜有报道表明其在神经外科领域的应用。本研究旨在评估SonicWeld Rx系统在小儿神经外科中的实用性。
本研究纳入11例儿科患者（10例男孩，1例女孩），他们因烟雾病、脑肿瘤和蛛网膜囊肿接受开颅手术。他们的平均年龄为6.4岁，范围在4至10岁。6例患者应用LactoSorb系统，5例应用SonicWeld Rx系统。
SonicWeld组的螺钉固定所需时间（6.5±1.4秒）显著短于LactoSorb组（13.4±2.8秒），p<0.05。两组的固定强度质量均足够。没有与可吸收固定装置相关的围手术期并发症。术后3个月的三维颅骨CT检查未发现骨瓣移位。平均21个月内未发现头皮并发症。
SonicWeld Rx系统在小儿神经外科领域将骨瓣固定至颅骨时操作简便且实用。
