Dermal fillers are a popular choice for those looking to reduce the signs of aging and restore volume to their face. However, it is important to understand the risks associated with these injections, as they can have serious consequences if not administered properly. In this article, we will discuss the five best danger injection zones for dermal fillers, as well as the importance of understanding 3D anatomy and injection strategies. We will also discuss the qualifications recommended by Health Education England (HEE) for administering non-invasive cosmetic procedures.The five best danger injection zones for dermal fillers are between the eyebrows and just above the nose, lines between the corner of the nose and the mouth, glabella, nasal region, forehead and nasolabial fold.
It is recommended to use a low-G filler around this region using the serial puncture technique. Understanding 3D anatomy is essential to avoid vascular complications, as vessels can travel through tissues at different depths along the same pathway. In its latest guidelines on qualification requirements for the administration of non-invasive cosmetic procedures, Health Education England (HEE) recommends that courses teaching injectables such as botulinum toxin and dermal fillers offer 50% theoretical training. Accidental intra-arterial injection with a filler product can cause obstruction of the central retinal artery, so it is important that all physicians who administer dermal filler injections have a thorough and practical knowledge of vascular anatomy.
The injection strategy your injector uses is also crucial to getting a good result. This includes the type of filler, volume, delivery, and injection locations. In-depth knowledge of facial anatomy through safety techniques such as vessel mapping, aspiration, knowledge of its depths, when you can bolus and when not, when to use a needle instead of a cannula or a visa are all important considerations when injecting dermal fillers. In addition to avoiding these danger zones, there are numerous strategies for WHERE (and HOW MUCH) the dermal filler should be injected to get the desired results.
For example, it is recommended to inject small amounts of fillers with extreme caution in patients with previous rhinoplasties, as the anatomy may have changed and residual sclerosis makes the vessels less mobile in their environment, increasing the risk of being cannulated. In other words, the lower-risk strategy involves deep injection in the upper part of the forehead (below the galley) and very superficial injection in the lower zone, and taking additional precautions in the zone of deep to superficial vascular transition.The middle temporal vein drains into the jugular and can cause a distal pulmonary embolism if a dermal filler is injected. Due to its anatomical position in the upper third of the nasolabial fold (FLN), the subalar artery constitutes an anatomical danger zone for filler injections often requested in this area of the face.In conclusion, it is important to understand all potential risks associated with dermal filler injections before undergoing treatment. It is essential that injectors have a thorough knowledge of facial anatomy and injection strategies in order to avoid any potential complications.
By following these guidelines and avoiding these danger zones, you can ensure that you get a safe and effective result from your dermal filler injections.
