Abstract
Sinonasal anatomy is complex and well assessed on imaging, particularly using CT and MRI. Coronal imaging is the preferred clinically applicable plane, allowing assessment synonymous to clinical evaluation whilst sagittal views also provide useful anatomical information. Possible surgical hazards including anatomical variants must be addressed in the radiology report. CT imaging is commonly utilised in the evaluation of chronic rhinosinusitis, where the use of the ‘CLOSED’ acronym can provide a checklist for radiologists in sinonasal assessment in order to aid in surgical planning. Complications of sinusitis, namely infection including intracranial involvement and non-infective aetiologies such as a mucocele can also be assessed on imaging. Unilateral nasal mass lesions must also be carefully interrogated radiologically, often warranting both CT and MRI evaluation. This chapter aims to highlight the optimum use of radiological investigations, provide an overview of radiological anatomy and review the most common pathologies of the sinonasal tract.
