What's the risk of embolism and/or necrosis after nonsurgical nose reshaping?

?? If you can explain what you mean by nonsurgical nose reshaping, I might be able to help you.
Small but real risk. Injectable fillers may be used to to minimize appearance of the nasal hump. While this can be a quick "fix" does not permanently improve the appearance of the nose and does come with certain risks. Blood flow to the skin can be disrupted with filler injections - inadvertent injection into a small blood vessel or from pressure on blood vessels or skin itself - may result in tissue death/necrosis.
Very minimal. If you are referring to injectable fillers I feel it should be less than 1% in capable hands. The nasal vasculature at risk for an embolus is subdermal (just under the skin) and the vast majority of filler needs are deeper tissue planes. With small amounts and careful observation, emboli causing any necrosis resulting in scarring can be avoided. Aestheticspecialtycentre. Com.
What is used? Not clear what 'nonsurgical' nose shaping you are asking about. Use of fillers (like injectible silicone to accepted materials) have potential of damaging blood vessels and causing tissue loss & bear the potential of entering into the venous system around the nose which can embolize to the cavernous sinus in the cranium. Can be life threatening.

Is there a risk of arterial embolism with non surgical nose reshaping?

Explain non-surgical. It is not recommended that gel or liquid silicone be placed. There are silastic implants for that purpose, but these are placed by small incisions inside the nasal passageways.
Not if done right. Non-surgical nose reshaping is a wonderful procedure for the right kind of patient. Any risk of complications, which would include blood clots, or skin loss, have to do with improper placement of the material. I agree, no silicone, but other fillers work just fine and give beautiful results in the right hands. Make sure your surgeon is experienced with this technique.
Yes. Non-surgical nose reshaping usually refers to the use of fillers to improve nasal contours. Although very rare, there is a risk of arterial embolism whenever injectables are used anyplace in the body.
Yes. It is possible to inject filling material into an artery during filler injection. A properly trained physician can avoid this, but is also trained on how to recognize and treat this early.
Yes, but low. Yes but the riks is low. Some feel the use of blunt cannulae may diminish this risk.
Yes, but low. Low risk but not zero. Make sure any such procedure is done by a board certified facial plastic surgeon.
Possible. However, in most published cases, these lesions resolved with topical steroid therapy.
