“…The authors explained that the variability of measurements gained in the Dolphin ® Imaging Software may be caused by the fact that even though the anatomical landmarks may be identified by multiplanar guide, the selection of the initial and final points must be made on the same spatial plane. This comprises the identification and measurement of anatomical landmarks [18]. Power et al [19] also found weaknesses in the Dolphin Imaging Software.…”

Background. Pterygomaxillary dysjunction is the most dangerous part of Le Fort I osteotomy. Preoperative evaluation of the patient's anatomy in 3D imaging software may help to choose an appropriate surgical approach and minimize the risk of the operation. Objectives. The aim of this study was to evaluate the reproducibility of linear measurements performed at the pterygomaxillary junction using open source software. Material and Methods. The study population consisted of 101 patients who underwent a CBCT examination for reasons independent of this study. Eight anatomical landmarks in the pterygomaxillary junction were pre-defined to measure the thickness and length of this structure. Linear measurements between the landmarks were performed in duplicate by two independent observers over 14 days. The data was evaluated using Netfabb Basic Studio (Netfabb Company, Parsberg, Germany). An analysis of variance (ANOVA) studied the influence of certain factors (side, observer, and repetition) on the accuracy of the measurements. Results. The mean value of all the valid measurements was 2.76 mm for thickness and 16.71 mm for the length of the pterygomaxillary junction. ANOVA showed no inter-observer bias. None of the observers reported statistically significantly higher or lower values than the other observer (p > 0.05). The intra-observer reproducibility was better than the inter-observer reproducibility of the measurements. The intra-and inter-observer reproducibility analyzed for log-transformed absolute values of differences between the measurements was very good (< 0.5 mm mean difference for linear values reconstructed from the log). The results were from a relatively large population and offered useful and reproducible measurements using open source software during the planning of orthognathic procedures. Conclusions. The results confirmed the reproducibility of the measurements. This method may be used during the diagnostics and planning of Le Fort I osteotomy. We also propose further evaluation of open-source software programs. Their comparison may help standardize the planning of orthognathic procedures (Dent. Med. Probl. 2016, 53, 3, 320-331).

Estimation of stature from femur length measured using computed tomography after the analysis of three-dimensional characteristics of femur bone in Korean cadavers

et al. 2017

Estimation of stature is a basic and important forensic procedure in identifying decomposed or skeletonized bodies. Due to advances in radiologic equipment, forensic science frequently uses computed tomography (CT) and software to apply these findings to investigations. Technical developments have increased the accuracy of the measurement of various bones. However, there are still some inaccuracies, such as defining correct landmarks in three-dimensional (3D) images. Femur length is frequently used for calculation of stature, but because it is a 3D structure, the digital image may not always correlate with the femur length measured with an osteometric board. However, more studies are now showing that the maximum femur length calculated in 3D imagery is comparable to the maximum femur length calculated using an osteometric board. This study used digitalized data of the femur obtained from the CT image through the specialized software. The digitalized femur images were put on the virtual osteometric board, which helped us to understand the anatomic characteristics of the femur and to confirm that the maximum femur lengths calculated in 3D images are similar to the results obtained using an osteometric board. These data were used to obtain a stature estimation formula for the Korean population.
