These complications are not just casued by botulinum injection, but also many other types of injection.
About accidental injury to blood vessels during injection:
There are many points when injecting botulinum toxin, and the layers are generally in the muscle layer. During the process of needle insertion from the skin surface, invisible large and small blood vessels (both arteries and veins are possible) will inevitably be pierced, which will cause local obvious. Bleeding and swelling is not uncommon. Therefore, I say that doctors must have excellent injection skills, as well as a certain understanding of relevant anatomy and facial aesthetics.
Since the needles for botulinum toxin injection are mostly small needles of 30G or even finer, even if a blood vessel is punctured, it will not cause much damage, and there is no need to worry about affecting the central nervous system through the blood-brain barrier. A few minutes of gentle pressure on the cotton swab should stop the bleeding.
After the operation, the patient can be iced for 10 to 15 minutes according to the doctor's instructions, and the blood vessels can be contracted by the physical principle of thermal expansion and cold contraction, and most of the formed hematoma can also subside.
When the injection needle is inserted into the blood vessel, the patient may feel more pain at the needle point than other surrounding points (or may not feel it), and there is no need to worry that the injection of botulinum toxin into the blood will cause serious vascular embolism like hyaluronic acid. There is no need to worry that botulinum toxin will cause systemic poisoning when it enters the bloodstream. Usually, when the blood vessels are damaged, the single-point injection volume is only 2u. Even if all these toxins are injected into the blood vessels, they will be diluted to a great extent.
The common postoperative adverse reaction is that the amount of botulinum toxin injected into the target muscle may be slightly less than the contralateral side. Imperceptible. If there is a relatively obvious asymmetry, it is only necessary to make a small supplementary injection at the point where the expression muscle is slightly less inhibited about 1 month after the operation.
Adding a small amount of triamcinolone acetonide injection to botulinum toxin can indeed enhance the face-lifting effect of botulinum toxin, increase the maintenance time of the effect, and reduce drug resistance. For patients with ineffective botulinum toxin, it may be a reasonable treatment method.
The main manifestations are about 2 weeks after injection, facial depression, most obvious at 1 month, depigmentation, painless, and occasional itching. Of course, it can usually recover by itself in 6 months.
