Nose filler: What are the risks?

This is a good question and its a conversation I have with my patients regularly. You are correct that there have been (rare) reports around the world of blindness with filler treatment. The reason this can occur is that there are many interconnections between the blood vessels of the face, and if filler product is injected inadvertently into an artery it can travel forwards or backwards in the vessel and cause a blockage, which in the case of the eye can be very serious.
The key to providing safe treatment in the nose, and anywhere else in the face, is a thorough knowledge of the anatomy and correct technique when carrying out the injections.
You should feel free to raise this question with your doctor, and he/she should be able to explain the steps they take to provide safe treatment. 

Hi kleraa,
There are rare but documented cases of necrosis, vascular occlusion, even blindness when injecting fillers. While the nose is highly vascularized, an expert doctor can inject safely. Thorough knowledge of anatomy and a good track record keeps you on the safe side. Some doctors also prefer to use the cannula which is blunt and sort of slides over sensitive nerves and blood vessels. You can also use hyaluronic fillers which are temporary but can be dissolved by hyaluronidase instead of fillers like Bellafill which can't be dissolved with ease if the procedure goes wrong or if you are unhappy with the results.
All the best,
