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
