| Popis: | PURPOSE To detect anatomical conditions that may benefit from an orbital rim advancement procedure in patients suffering from Graves orbitopathy. METHODS In postprocessed 70 clinical CTs from adults of white European ethnicity with unaffected orbits, the authors assessed the intra- and interindividual variability of the orbital rim angulation and orbital rim position relative to their medial rim parts. This included morphometrical analysis and computer model visualization using Amira software (version 5.3.1, Visage Imaging GmbH, Berlin, Germany). RESULTS Significant variation was observed in rim angulation, varying up to 16.6° in different individuals. A large variability of the sagittal rim position became evident, with the highest at the lateral orbital rim being 1.1 cm. CONCLUSIONS These anatomical data may be used to benchmark the given Graves orbitopathy patients. CT assessment to detect and quantify orbital rim pro-/retrusion may help to decide whether orbital rim advancement may be considered for orbital decompression/enlargement. |
