Modification of the measurement of the major variables in mandibular condylar fractures: angulation of sidewards displacement and shortening of the height of the ramus

Our aim was to improve the accuracy of measurement of the angulation and the shortening of the height of the ramus in fractures of the mandibular condyle using modified methods. We analysed spiral computed tomography (CT) of 67 unilateral fractures with the OsiriX v 5.0 (©Pixmeo Sarl) and Mimics 19.0 (©2016 Materialise NV, Belgium) and analysed them with SPSS (version 24.0, IBM® SPSS®). Angulation was measured using both the traditional method and our modified method. The results showed significant difference (p = 0.000), and the values measured with the traditional method were lower, which is consistent with geometric analysis.
