This study compares the morphological concordance between CT (computed tomography) and cone beam in sinus on 26 validated items. CT and cone beam is performed on each patient. Performances of these two imagery technics seem to be closed. Nevertheless, the exposure of the ionizing radiations is lower with the cone beam.

The reproducibility of the measurement between the two neuroradiologists will be assessed by intraclass correlation coefficient, based on 26 benchmarks of primary endpoint. Similarly inter-observer reproducibility will be assessed for the 36 specific criteria

| Diagnosis concordance radio-endoscopic and radio-surgical | Radio-endoscopic surgical concordance and radio will be estimated by calculating the proportion of concordant diagnoses between the radiological evaluation and cone beam scanner and endoscopic evaluation obtained at the first nasal endoscopy and radiological evaluation between the scanner and cone beam and intraoperative assessment in case of surgery. The investigators then compare the radio-endoscopic surgical concordance and radio and the cone beam scanner. | 1 day |
