Chronic inflammatory disease of paranasal sinuses

Purpose. Evaluation of the clinical Value of imaging techniques for chronic inflammatory disease of paranasal sinuses. Materials and methods. Beside clinical tests imaging of the paranasal sinus es is based on the techniques like conventional X-ray studies, ultrasound, computed tomography and magnetic resonance techniques. Results. The value of conventional X-ray is lowered and is today focused on the diagnosis of acute sinusitis with fluid level and the detection of inf lammatory foci. Spiral-CT using transverse and coronal orientation or refor matted images is considered as the diagnostic method of choice for the majo rity of clinical questions. MRT allows additional diagnostic informations i n completely obstructed maxillary sinuses and patients with suspected anter ior skullbase involvement. Conclusion. Imaging techniques do provide substantial diagnostic informatio ns in patients with chronic sinusitis.
