If you find the necrosis after filler injection, you need the management in a hurry.
If there is necrosis, you feel pain, heating sense on your nose and some bruise around the injected site IN A DAY!!!
Because the filler material would block the blood circulation, the patient needs emergent mangement to survive the nose.
The hyperbaric oxygen therapy is the most important therapy.
If the necrosis proceeds, the nasal reconstruction is needed like this picture.
In our clinic, we do the nasal reconstruction and fulfill the effective hyperbaric chamber.
