For patients with facial asymmetry, complete and precise diagnosis, and surgical treatments to correct the underlying cause of the asymmetry are significant. Conventional diagnostic radiographs (submento-vertex projections, posteroanterior radiography) have limitations in asymmetry diagnosis due to two-dimensional assessments of three-dimensional (3D) images. The advent of 3D images has greatly reduced the magnification and projection errors that are common in conventional radiographs making it as a precise diagnostic aid for assessment of facial asymmetry. Thus, this article attempts to review the newly introduced 3D tools in the diagnosis of more complex facial asymmetries.
对于面部不对称的患者,进行完整而精确的诊断以及通过手术治疗纠正不对称的根本原因非常重要。传统的诊断性X光片(颏顶位片、正位片)由于对三维(3D)图像进行二维评估,在不对称诊断方面存在局限性。3D图像的出现极大地减少了传统X光片中常见的放大和投影误差,使其成为评估面部不对称的精确诊断辅助工具。因此,本文试图综述新引入的用于诊断更复杂面部不对称的3D工具。
