Abstract EN
Background.
Preoperative imaging of the nose and paranasal sinus is standard in otorhinolaryngology.
Previous studies on phantoms demonstrated the potential for dose reduction of cone beam computed tomography (CBCT) by varying the application parameters.
Methodology.
Based on previous studies, the standard protocol of paranasal sinus imaging by CBCT was altered.
One hundred and fifty examinations using the old protocol (01/2010–01/2011, high dosage) and 150 examinations using the new protocol (09/2012–09/2013, low dosage) were evaluated and compared for the visibility of 17 anatomical structures, the Lund-Mackay Score, and technical parameters.
Results.
Alteration of the protocol resulted in a significant reduction in dosage (6.64 mGy versus 2.88 mGy).
Both groups showed the same amount of pathology (Lund-Mackay Score: 4.95±3.79 versus 5.26±5.77; p=0.558).
There was a significant better visibility of the anatomical structures (all visible = 1, nothing visible = 4) (results: 1.25 versus 1.17; p=0.001) in the low-dosage group.
Conclusion.
Despite a significant reduction in the applied dosage, reliable visualization of the bony anatomy of the anterior skull base is possible by CBCT.
This demonstrates the need for the discussion of the required clinical imaging quality.
