Nasal Endoscopy
What is nasal endoscopy?
Nasal endoscopy is an examination procedure that allows an ear, nose and throat (ENT) specialist to view the nasal passages, paranasal sinuses as well as the pharynx (throat) under magnification.
Either a flexible or rigid (non-flexible) endoscope is inserted through the nostrils after local anaesthesia has been applied to minimise discomfort in the nose.
Why do you need a nasal endoscopy?
Your ENT specialist may recommend a nasal endoscopy as a diagnostic procedure for nose-related symptoms such as :
- Nasal obstruction or congestion
- Nose bleeds
- Nasal discharge (e.g. mucus or pus)
- Sinus pressure or pain
- Loss of smell
Nasal endoscopy can also be performed as part of treatments such as:
- Suctioning of pus for microbial testing (viruses, bacteria, fungi)
- Biopsy of polyps
- Cautery to stop a nose bleed
- Removing a foreign body in the nose
Nasal endoscopy is also conducted to see if a treatment for a nose or sinus problem is working, such as checking to see whether nasal polyps have shrunk.
What are the risks and complications of a nasal endoscopy?
Nasal endoscopy is a generally safe procedure, but it may have rare complications such as:
- Adverse reaction to the decongestant or anaesthetic
- Fainting
- Nosebleed
If you have a bleeding disorder or take blood thinners, you may have a higher risk of bleeding.
Your risks may also vary according to your age and other health conditions. Your doctor will discuss with you the risks before the procedure.
