Abstract

Statistical shape analysis captures the geometric properties of a given set of shapes, obtained from medical images, by means of statistical methods. Orthognathic surgery is a type of craniofacial surgery that is aimed at correcting severe skeletal deformities in the mandible and maxilla. Methods assuming spherical topology cannot represent the class of anatomical structures exhibiting complex geometries and topologies, including the mandible. In this paper we propose methodology based on non-rigid deformations of 3D geometries to be applied to objects with thin, complex structures. We are able to accurately and quantitatively characterize bone healing at the osteotomy site as well as condylar remodeling for three orthognathic surgery cases, demonstrating the effectiveness of the proposed methodology.

摘要

统计形状分析通过统计方法捕捉从医学图像中获得的给定形状集的几何特性。正颌外科是一种颅面外科手术，旨在矫正下颌骨和上颌骨的严重骨骼畸形。假设为球形拓扑的方法无法表示具有复杂几何形状和拓扑结构的解剖结构类别，包括下颌骨。在本文中，我们提出了基于三维几何非刚性变形的方法，以应用于具有薄而复杂结构的物体。我们能够准确且定量地表征三例正颌外科手术病例中截骨部位的骨愈合以及髁突重塑情况，证明了所提方法的有效性。
