Modal Anatomy of the Ethmoid Bone — AME  

Anatomic Abnormality Clinical Trial

Official title: Constitution d'un modèle 3D d'Anatomie Modale de L'Ethmoide Par intégration de Multiples Instances d'Acquisition

Status Not yet recruiting

Clinical Trial Summary

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.

Clinical Trial Description

Non-interventional descriptive research. Sinus CTscans (period 2016-2019) will be reviewed from the PACS database of the CHRU of Nancy and selected in individuals without sinus pathology. All CT-scans will be fully anonymized. 26 landmarks will be pointed out to enable : 1. prior images alignment (centering on the median line, realignment rotations then resizing) 2. a mean and median calculation, allowing to establish a mean and median ethmoid model 3. calculation of standard deviations for each voxel The structures obtained in this way (bone, tissue or aerial) will be described anatomically. ;
