The diagnosis of Sinusitis is made after review of patient's medical history and completion of a full clinical examination. CT scan is the accepted form of radiologic evaluation. Scans with axial, coronal and reconstructed saggital views are the most useful.
Clinical examination includes anterior rhinoscopy and nasal endoscopy.
This can be carried out effectively under topical or local anesthesia. Rigid nasal endoscopy affords optimum viewing of the sinuses in different angles with the various angled Hopkins telescopes.
