what does this mean. TECHNIQUE: Noncontrast axial 2 mm sections were obtained through the maxillofacial/paranasal sinus regions. Multiplanar reconstructions were obtained in the sagittal and coronal planes. The CT scan was performed with attention to patient radiation dose reduction, as low as reasonably achievable (ALARA), while maintaining diagnostic image quality. This includes appropriate physician-selected protocols to tailor the exam for minimum exposure. FINDINGS: Nasal septum : Deviated to the right with a septal spur. Paranasal sinuses & nasal cavity : Chronic inspissated secretions in the left lateral aspect of the sphenoid sinus and left pterygoid recess. Small retention cyst in the left maxillary sinus. The rest of the paranasal sinuses are clear. Middle& Inferior turbinates : Left concha bullosa is noted. Cribriform plates, fovea ethmoidalis, lamina papyracea : normal Haller& Onodi cells : none Uncinate process, maxillary infundibulum & middle meatus : normal Frontal& sphenoid-ethmoidal recesses : Left sphenoid -ethmoidal recess is obstructed due to mucosal thickening. Anterior clinoid process & optic canals : Normal. Orbits: Orbital soft tissues are normal. Included skull base : Unremarkable. Included brain : Unremarkable. Small maxillary and mandibular tori are noted. Impression IMPRESSION: Nasal septum is deviated to the right with a septal spur. Chronic inspissated secretions in the left lateral aspect of the sphenoid sinus with an obstructed left sphenoid -ethmoidal recess. Small retention cyst in the left maxillary sinus. Both maxillary ostia are patent.
