Rhinoscopy
Anterior and posterior examination of the nasal cavity and nasopharynx, typically combined with CT under the same anaesthetic.
Indications
- Chronic nasal discharge, sneezing or epistaxis not explained by initial work-up
- Suspected nasal or nasopharyngeal foreign body
- Targeted biopsy following cross-sectional imaging
Limitations
- Frontal sinuses and some recesses difficult to assess
- Haemorrhage may limit visualisation
- Biopsies may be non-diagnostic; CT generally better for extent and bony involvement
