Overall a nasal endoscopy is a relatively low-risk procedure. However, as with any procedure, there's always the chance of potential nasal endoscopy side effects or complications, such as bleeding and mucosal trauma, especially in those who already have an increased risk for bleeding like those taking anticoagulant medicines (Coumadin, Plavix, etc.) or aspirin.
You could experience adverse reactions to anesthetics or topical decongestants received before your procedure. Therefore, your healthcare professional will verify if you have any allergies before they administer a topical medication.
Before your procedure, make sure you ask your physician if you need to stop taking any medications, such as blood thinners. Your physician will likely provide you with specific instructions about what you should and shouldn't do before your procedure. For instance, you may be asked to refrain from eating and drinking for a certain period of time before your procedure.
Rarely is the procedure painful, however, if you have an unusually narrow nasal cavity or swollen nasal lining, you could experience some mild discomfort. Your otolaryngologist will spray your nose right before your nasal endoscopy to minimize discomfort with a:
1. Local anesthetic, temporarily numbing your nose and helping to minimize your likelihood of sneezing due to sensitivity.
2. Nasal decongestant, gently reducing any nasal membrane swelling you have to provide the endoscope with an easy passage.
They may use a pediatric-sized endoscope or additional numbing spray to prevent and ensure there's no discomfort.
