title: [The diagnostic reliability of the occipitomental radiograph of the paranasal sinuses. Correlation with magnetic resonance tomography].
abstract: 100 conventional occipitomental radiographs of the paranasal sinuses were studied independently by five radiologists. Predictive values were determined, based on MRI as the gold standard. Sensitivity and specificity for detection of mucosal thickening in the sinuses were: maxillary sinus: 0.73/0.76, frontal sinus: 0.20/0.85, ethmoid sinus: 0.38/0.87, sphenoid sinus: 0.14/0.96. In the maxillary sinus polypoid thickening was demonstrated with a significantly higher sensitivity than that of diffuse mucosal thickening (0.82 versus 0.65, Chi-square-test, p less than 0.01). Because of the low predictive values the occipitomental view is insufficient to assessing mucosal thickening in the paranasal sinuses, with the exception of polypoid mucosal thickening in the maxillary sinus.
