IMAGING OF PARANASAL SINUSES

IMAGING OF PARANASAL SINUSES

Plain radiographs are of limited value in the assessment of sinus disease. CT is far superior in demonstrating sinus pathol ogy and for assessing bony anatomy to plan any surgical inter vention. CT scans are acquired and reconstructed to produce images in axial, coronal and sagittal planes. The three planes allow the drainage of the frontal sinus to be identified and important surgical landmarks can be reviewed preoperatively , including the cribrif orm plate, anterior skull base, lamina papyracea and location of the anterior ethmoid artery . MRI is useful in sinus pathology to assess any intracranial or orbital extension of disease. IMAGING OF PARANASAL SINUSES
