Nasoendoscopy

A nasoendoscope is an extremely useful tool for examining the nasal cavity. Before placement it is more comfortable for the patient if you administer some local anaesthetic into the nasal cavity. This can be done by injecting the anaesthetic from a syringe into each nostril. Once this has been given sufficient time to take effect, the nasoendoscope can be inserted. The scope shows the nasal turbinates and can extend into the post nasal space. If extended far enough the vocal cords can be visualised.
