Traumatic brain injury is a leading cause of death and disability worldwide, with nearly 90% of the deaths coming from low- and middle-income countries. Severe cases of brain injury often require a craniectomy, succeeded by cranioplasty surgery to restore the integrity of the skull for both cerebral protection and cosmetic purposes. The current paper proposes a study on developing and implementing an integrative surgery management system for cranial reconstructions using bespoke implants as an accessible and cost-effective solution. Bespoke cranial implants were designed for three patients and subsequent cranioplasties were performed. Overall dimensional accuracy was evaluated on all three axes and surface roughness was measured with a minimum value of 2.209 μm for Ra on the convex and concave surfaces of the 3D-printed prototype implants. Improvements in patient compliance and quality of life were reported in postoperative evaluations of all patients involved in the study. No complications were registered from both short-term and long-term monitoring. Material and processing costs were lower compared to a metal 3D-printed implants through the usage of readily available tools and materials, such as standardized and regulated bone cement materials, for the manufacturing of the final bespoke cranial implants. Intraoperative times were reduced through the pre-planning management stages, leading to a better implant fit and overall patient satisfaction.
创伤性脑损伤是全球死亡和残疾的主要原因,近90%的死亡发生在低收入和中等收入国家。严重的脑损伤病例通常需要进行颅骨切除术,随后进行颅骨成形术,以恢复颅骨的完整性,达到保护大脑和美容的目的。本文提出了一项研究,旨在开发和实施一种用于颅骨重建的综合手术管理系统,该系统使用定制植入物作为一种可及且经济高效的解决方案。为三名患者设计了定制颅骨植入物,并随后进行了颅骨成形术。在所有三个轴向上评估了整体尺寸精度,并测量了表面粗糙度,3D打印原型植入物的凸面和凹面的Ra最小值为2.209μm。参与该研究的所有患者的术后评估报告显示,患者的依从性和生活质量有所改善。短期和长期监测均未记录到并发症。通过使用现成的工具和材料,如标准化和规范化的骨水泥材料来制造最终的定制颅骨植入物,与金属3D打印植入物相比,材料和加工成本更低。通过术前规划管理阶段减少了手术时间,从而使植入物更贴合,患者总体满意度更高。
