An Approach for the Measurement of the Surface Area of Scalp Flap over the Cranial Defect after Decompressive Craniectomy

目的该文旨在介绍一种简单、快速并通用的测量方法,用于去骨瓣减压术后头皮表面积的测量。方法第一步,获取颅脑损伤病人去大骨瓣减压术后的颅脑CT图像,并将其导入Mimics软件;第二步,基于界定阈值,经Mimics软件三维化处理Dicom格式的原始图像获得颅脑和颅骨的三维几何模型;第三步,利用Mimics中的分割工具和测量工具对三维颅脑模型进行切割、分离、测量;第四步,通过数学计算方法估算出缺损区域的头表皮面积。结果应用该文所述的测量方法估算出了不同人群在不同颅脑损伤位置处的缺损区域头皮表面积。结论该文阐述了一种简单、快速、通用的新测量方法,运用此方法可以方便地估算出缺损区头皮表面积。

Objective To introduce a simple, fast and universal measuring method used in measurement of the surface area of scalp flap over the cranial defect after decompressive craniectomy. Methods The first step： CT images of the patient with craniocerebral trauma after decompressive craniectomy were obtained and imported into Mimics. The second step： based on the defined threshold, the 3D geometric models of brain and skull were reconstructed after the original Dicom format pictures three-dimensional processed by Mimics. The third step： based on the two builded 3D models, utilizing the segmentation and measurement tools of Mimics to conduct cutting, splitting and measuring operations for the 3D model of brain. The forth step： estimating the surface area of scalp flap over the removed bone flap by using mathematical computation methods. Results The application of the introduced method estimated the surface area of scalp flap over the cranial defect of different people with different position of craniocerebral trauma. Conclusions This paper introduces a simple, fast and universal new measuring method. We can conveniently estimate the surface area of scalp flap by using the introduced method.
