Abstract
There are no quantitative standards for the volumetric measurements of the orbit after Le Fort III advancement. CT Scan images have given the opportunity to compare with accuracy the real anatomical changes, thus the functional improvements, resulted after a surgical treatment. Pre-operative (T0) and post-operative (T1: 6 months after surgery) 3D craniofacial CT scans of the subjects were collected and retrospectively analysed. Image segmentation of the anatomic structures of interest and the 3D graphic rendering were done by using the Dolphin Imaging Plus (TM) 11.0 software. This study showed that the orbital advancement in Caucasian subjects after Le Fort III advancement was significant and produced a critical augmentation of the orbital volume and correction of the ocular bulb proptosis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
