可吸收固定系统在儿童后颅窝肿瘤开颅骨瓣复位手术中的应用

Repositioning of cranial bone flaps using bioabsorbable fixation system after posterior fossa craniotomy in children

目的观察可吸收固定系统在儿童后颅窝肿瘤开颅手术骨瓣复位固定中的作用。方法对15例7个月～14岁开颅游离骨瓣成形切除颅内病变后需骨瓣复位固定的患儿，采用可吸收固定系统材料进行骨瓣复位固定，观察术后局部伤口及骨瓣复位和全身情况变化。结果所有患儿术后1周CT复查显示骨瓣复位良好，无伤口红肿、疼痛和感染发生；1例皮下少量积液，经穿刺抽吸和加压包扎1周内消失。随访3～23个月，平均随访10．25个月，患儿术后切口恢复良好，外观正常，无发热、局部凹陷及红肿等异常表现，CT或MRl扫描均无塌陷、移位及伪影表现。结论近期观察结果显示在儿童后颅窝肿瘤开颅手术应用可吸收固定系统材料进行骨瓣复位固定简单安全，固定可靠，且能消除术后CT或MRI复查时金属固定材料导致的伪影。

Objectire To study the safety and efficacy of bioabsorbable fixation system for repositioning of cranial bone flaps after posterior fossa craniotomy in children. Methods From July 2010 to March 2012,15 patients with posterior fossa tumor underwent surgery in this institute. Bioab- sorbable fixation system was used to reposition cranial bone flaps. After surgery, the healing of surgical incisions and recovery conditions were observed and retrospectively analyzed. Resnlts After operation, no pain, infection, redness and swelling of surgical incision was observed. CT or MRI scan showed good positioning of cranial bone flap after operation. Small amounts of subcutaneous hydrops occurred on 1 patient and disappeared after 1 weeks＂ paracentesis and pressure dressing at the puncture site. All pa- tients were followed up for 3 to 20 months,with a mean duration of 10. 25 months. All patients surgi- cal incisions healed well with a good appearance. CT and MRI scans showed good positioning of cranial bone flap without subside, displacement or artifacts. Conclusions This study suggests it is safe and effective to reposition of cranial bone flaps using bioabsorbable fixation system after posterior fossa craniotomy in children.
