摘要
目的总结桥小脑角肿瘤21例患者，借助三维个体化数字解剖技术行乙状窦后入路显微手术的临床经验，评价该技术在处理桥小脑角肿瘤的应用价值。方法2011年1月至2011年11月共收治桥小脑角肿瘤21例，术前行薄层CTA扫描，数据经3Dview软件重建局部结构，根据解剖标志物设计个体化骨窗范围，术中根据三维个体化解剖模型制作骨瓣及制定显微手术方案行乙状窦后入路显微手术。结果所有病例骨瓣均一次成型并复位，无入路相关并发症，术野暴露良好，复位的骨瓣在随访中愈合良好。术后随访3～12个月，均行CT及MRI检查，无1例出现脑脊液漏或皮下积液，无1例出现手术入路相关并发症。术后CT检查均显示骨瓣无移位，并且骨瓣生长良好．三维重建更直观显示颅骨固定及愈合情况。结论根据三维个体化解剖技术施行桥小脑角肿瘤的显微手术，能减少术后相关并发症发生。
Objective To summary the microsurgery clinical experience of 21 patients with cerebel- lopontine angle tumor by the help of three dimensional individual digital anatomy. And to evaluate the value of three dimensional individual anatomy in the treatment of tumors in cerebellopontine angle. Methods Between January 2011 and November 2011, 21 patients with various cerebellopontine angle tumor, managed at the Third Affiliated Hospital of Sun Yat-Sen University, underwent CTA scan, and reconstruct the local anatomy by 3D view software. According to the individual anatomical model, the microsurgery program by restrosig moid approach was developed. Results All patients had reposition of the bone flap at original site after craniectomy during the same operative setting mentioned above with retrosigmoid approach. No compli- cation was noted. Patients did not have any delayed postcraniectomy pain at operation site. Postoperative computed tomography of the skull showed good healing and shaping of the suboccipital bone at the surgical region. Conclusion With the help of three dimensional individual anatomy, the microsurgery of cerebello- pontine angle tumor underwent less postoperative complications. This study provides a safe and effective indi- vidualized microsurgical methods by restrosig moid approach.
