Anatomic Abnormality Clinical Trial
— AMEOfficial title:
Constitution d'un modèle 3D d'Anatomie Modale de L'Ethmoide Par intégration de Multiples Instances d'Acquisition
The creation of a 3D model of modal anatomy of the ethmoid could, like other parts of the body, improve anatomical, radiological and perhaps even surgical learning. Anatomical variations might constitute a "background noise" of the modal anatomy, which can be attenuated by multiplying the instances of acquisitions. The objective of this work is to establish modal anatomy of the ethmoid by the analysis of a large number of CT-scan acquisitions carried out in individuals with no acquired sinus pathology.

Primary | Descriptive study of the anatomy of the final 3D model | Descriptive study
The study aims to produce the "modal" (generic) model from all the individual sub-models. The structures obtained will be described anatomically by ENT experts: the created model will be described in comparison with anatomical data from literature: constant structures (e.g. middle turbinate, inferior turbinate, or orbital wall) will be listed and described (sites of insertion, direction, form), while variations in anatomical structures will be described through the variance (variances of voxels, pooled for each anatomical sub-site) (e.g. anterior ethmoid, sphenoid...). The heat map of voxels' variances will be superposed on the final model. No scale/physiological parameter/questionnaire can be used for anatomical description of a single model. Therefore we don't really understand your remark "Please further specify the measurement that will be used (e.g., descriptive name of scale, physiological parameter, questionnaire) to assess this outcome measure." |
Through completion of the study: 1 month (The model will be available only at the end of the study, after implementation of all CT-scans) |
