To surgically remove osteoma and to keep an optimal cosmetic profile would be very challenging. To solve the difficulty, we utilized the three-dimensional (3D) printing technologies in generating a patient-specific instrument guide (PSIG) for the safe removal of a skull bone tumor.
The preoperational brain computed tomography (CT) provided the digital imaging with thin slices, and then images were reconstructed into a 3D skull model. Based on the model, we designed a PSIG to make landmarks on the osteoma to avoid excessive removal of the skull bone. During the operation, the surgeons could remove the osteoma piece by piece by using the landmark as a reference point.
The PSIG was successfully applied to remove an osteoma that measured 60 × 48 × 40 mm over the left frontoparietal skull of a female patient. The 3D CT reconstruction taken both before and 4 months after surgery showed a significant change in the appearance of the osteoma.
The PSIG was able to guide the surgeon in the safe removal of the skull osteoma, as well as in maintaining the cosmetic skull profile.
通过手术切除骨瘤并保持最佳的美观外形极具挑战性。为解决这一难题，我们利用三维（3D）打印技术制作了患者特异性器械导向器（PSIG），用于安全切除颅骨肿瘤。
术前脑部计算机断层扫描（CT）提供薄层数字影像，然后将图像重建为三维颅骨模型。基于该模型，我们设计了PSIG，在骨瘤上标记地标以避免过度切除颅骨。手术过程中，外科医生可将地标作为参考点逐块切除骨瘤。
PSIG成功应用于一名女性患者左额顶颅骨上一个尺寸为60×48×40mm的骨瘤切除。术前及术后4个月的三维CT重建显示骨瘤外观有显著变化。
PSIG能够指导外科医生安全切除颅骨骨瘤，并维持颅骨的美观外形。
