The head and neck surgeon is dependent on radiographic technology to diagnose deformity, plan surgery, and evaluate operative results. The development of computerized tomographic scanning has facilitated osseous definition as well as allowed study of intracranial and extracranial soft tissue. Nonetheless, the computerized tomographic image slice format requires an educated interpreter and a fertile imagination for correlation with physical findings. We have created computer software that presents computerized tomographic data as surface images that resemble photographs of the patient or a specimen skull. The program runs on standard computerized tomographic scanners, requires no operator intervention, and is efficient in computation time and space. The surgeon can directly visualize the osseous deformity and mathematically relate it to the overlying soft tissue. The surface images can be viewed from a variety of perspectives, with or without selected structures, such as removing the body of the mandible in the pseudo-Water's projection to demonstrate the palate. The image data can be manipulated to obtain a variety of useful results beyond the images themselves. The addition of this technology to the preoperative evaluation and longitudinal follow-up of patients with head and neck cancer has increased our understanding of the extent of their malignancy.
头颈外科医生依靠放射成像技术来诊断畸形、规划手术以及评估手术效果。计算机断层扫描技术的发展有助于清晰显示骨骼结构，并能对颅内和颅外软组织进行研究。尽管如此，计算机断层扫描图像的切片形式需要专业的解读人员，且需要丰富的想象力才能与体格检查结果相互关联。我们开发了一种计算机软件，它能将计算机断层扫描数据呈现为类似于患者照片或标本颅骨照片的表面图像。该程序可在标准的计算机断层扫描仪上运行，无需操作人员干预，且在计算时间和空间方面效率很高。外科医生可以直接观察到骨骼畸形，并从数学角度将其与覆盖其上的软组织相关联。表面图像可以从各种视角查看，可选择显示或不显示特定结构，比如在伪华氏位投影中移除下颌骨体以显示腭部。除了图像本身，还可以对图像数据进行处理以获得各种有用的结果。将这项技术应用于头颈癌患者的术前评估和长期随访，加深了我们对其恶性肿瘤范围的理解。
