Assessment of the Morphological Concordance Between CT and Cone Beam in Sinus Imagery
Assessment of the Morphological Concordance Between CT and Cone Beam in Sinus Imagery
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.
Inclusion Criteria:

 -  man or woman older than 18 years old

 -  patient affected by sinonasal pathology : who show one or more of the following
 functional sign : anosmia, pain with sinusal origin (frontal headache, lower-orbital
 throbbing pain increased in anteflexion, chronic unexplained headache), nasal
 blockage, runny nose, epistaxis requiring the realisation of a sinus imagery overview.

 Exclusion Criteria:

 -  Deprivation of liberty by administrative or legal decision

 -  patients under 18 years old

 -  Patients in emergency
