PARANASAL SINUSES

PARANASAL SINUSES
Internal inspection of  the nasal fossae can be achieved to a limited extent with the use of a Thudichum speculum. The anterior nasal septum, nasal vestibule and anterior inferior turbinate can be assessed. A more detailed examination of  the nose is possible with the use of  either rigid or flexible endoscopes and camera and the image is displayed on a monitor.
