Assessment of non-invasive chronic fungal rhinosinusitis by cone beam CT: comparison with multidetector CT findings.

Objective : To investigate the accuracy of cone beam CT (CBCT) to diagnose non-invasive chronic fungal rhinosinusitis. Methods : Preoperative CT evaluation of non-invasive chronic fungal rhinosinusitis was performed by CBCT (3D Accuitomo 170 (R)) and traditional multidetector CT (MDCT) (Aquilion 32 (R)) in 13 and 38 patients with non-invasive chronic fungal maxillary sinusitis, respectively, in different facilities. Detection of intrasinus calcification was compared between these two groups. Results : Detection of intrasinus calcification in patients with non-invasive chronic fungal maxillary sinusitis was higher in the MDCT group (84.2%) than the CBCT group (46.2%). Conclusion : CBCT is inferior to MDCT in detection of intrasinus calcification in patients with noninvasive chronic fungal maxillary sinusitis. CBCT is frequently used in the screening of the paranasal lesion, but it is not enough to evaluate non invasive chronic fungal maxillary sinusitis alone. Study design Retrospective study.
