摘要
目的:计算机辅助设计技术在医学领域得到了越来越多的应用,将计算机辅助设计技术引入到颅骨缺损的修复过程中,观察其修复效果。方法:选择2005-01/2006-12泸州医学院附属医院脑外科采用计算机辅助设计颅骨缺损成型技术修复颅骨缺损患者56例,对治疗均知情同意,且得到医院伦理道德委员会批准。所有病例经过CT扫描收集数据、缺损重建、钛网成型、模拟装配和手术修复等步骤完成修复过程;术后给以止血、抗炎、对症治疗;以手术切口一期愈合,无头皮下积血、积液,钛网无松动,外形美观为出院标准,出院随访6～18个月。结果:56例颅骨缺损患者全部进入结果分析,除1例术后并发短时脑脊液切口漏、1例发生硬膜外血肿外,无切口感染和头皮坏死,无颅内出血与术后癫痫,无修补材料外露、塌陷、松动等常见颅骨修补并发症发生;钛网与骨缺损区吻合良好,颅腔塑形满意,效果良好。结论:计算机辅助设计颅骨缺损成型技术简单易行,可有效减少术后并发症,提高修复效果。
AIM： Computer-assisted design （CAD） has been widely applied on the medical field. The purpose of this study was to evaluate the utility of CAD in skull defect reconstruction.
METHODS： With the approval of the hospital ethnic committee, 56 patients with skull defect repaired with CAD were recruited from the Department of Neurosurgery in the Affiliated Hospital of Luzhou Medical College from January 2005 to December 2006. Informed consents were obtained from all the patients. The treatment course included CT scan, data collection, defect reconstruction, titanium mesh molding, simulating assemble and operative repairing; After operation, all the patients were given to stop bleeding, anti-inflammatory and symptomatic treatment; the discharge standards included the primary healing of surgical incision, no hematocele and fiuidify under scalp, no loosening and removal of the titanium meshes and the beautiful appearance. All the patients were followed up for 6-12 months postoperatively. RESULTS： All the 56 patients with skull defect were involved in the result analysis. Among them, there was 1 patient complicated with extracranial hematoma and 1 patient with transient cerebral spinal leakage, but without symptom of incision and scalp necrosis. No patients appeared the common complications, such as intracranial hemorrhage, epilepsy, and titanium mesh displacement, looseness, deformation. The coincidence of titanium mesh and skull defect was very good, cranioplasty was also satisfied, and this result was better than traditional reconstructive ways. CONCLUSION： The technology of CAD used for the reconstruction of skull defect is convenient, effective and safe. This way can reduce the postoperative complications and improve the reconstructive results.
