正常成人阴茎及其毗邻组织结构的可视化研究

Visualization of the adult penis and adjacent structure of the Chinese visible human

目的建立正常成人阴茎及其毗邻结构的数字化可视模型,为阴茎整形修复获得手术前后形变参数及手术方案的选择,提供形态学依据。方法采用第三军医大学解剖学教研室建立的数字化可视人体数据集(chinesevisiblehuman,CVH)部分连续图像,运用表面绘制的方法,对阴茎及其毗邻组织结构进行计算机三维重建和立体显示。结果可视化模型可清晰显示阴茎内部及毗邻结构的形态、分布特点和相互间的三维空间解剖关系。重建图像能单独或联合显示,并可进行任意径线和角度的适时三维测量。结论阴茎可视化模型能够准确反映出该区域复杂的解剖学特点及其内部空间毗邻关系,可为成人阴茎整形修复外科手术提供重要的形态学数据来源。

Objective To build digitized visible model of the adult penis and adjacent structure of the Chinese visible human, providing morphological data for plastic plerosis of external genitals diagnosis and the adult penis surgery planning. Methods Cross-sectional images of fresh tissues from the Chinese visible human dataset and the visible penis and adjacent structure dataset were reviewed, the structures of the penis and adjacent structure were confirmed on a section-by-section basis. Three-dimensional computer reconstructions of the penis and adjacent structure were generated from these data by surface rendering. Results The quality of the computerized 3D-reconstructed images was distinct and perfect. The adult penis and adjacent structure were all reconstructed and displayed jointly. All reconstructed structures can be represented individually or jointly. Any diameter and angle of the structures reconstructed could be measured conveniently. Conclusions The digitized model of the penis and adjacent structure offer unique insights into the complex penis anatomy, providing morphological data for plastic plerosis of external genitals diagnosis and surgery planning.
