Dermal fillers are a popular non-surgical solution for facial rejuvenation, but they come with certain risks. Understanding the anatomy of the face and the potential danger zones for filler injections is essential to avoid vascular complications. In this article, we'll discuss the five most dangerous injection zones for dermal fillers and how to safely inject them. The three main classic anatomical hazard zones for filler injections are the glabella and forehead, the nasal and labial areas.
Understanding 3D anatomy is essential to avoid vascular complications. In fact, vessels can travel through tissues at different depths along the same pathway (Figure). 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 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, middle temporal vein, subalar artery, and central retinal artery.
It is recommended to use a low-G filler around this region using the serial puncture technique. The injection sites with the highest risk were glabella, nasal region, forehead and nasolabial fold. 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.
Accidental intra-arterial injection with a filler product can cause obstruction of the central retinal artery. Injecting dermal fillers into the face and hands can improve the appearance of facial lines and volume loss caused by age or certain medical conditions. Because the vascular network of the nose is superficial and below the dermis, filler injections should be performed deep into the musculo-aponeurotic layers, in the preperichondrial and preperiosteal planes to avoid injury or cannulation of the vessels. In addition, there are numerous strategies for WHERE (and HOW MUCH) the dermal filler should be injected to get the results you are looking for. Sandra has a long history of supporting Dr.
Rubinstein and other plastic surgeons and facelift surgeons to help patients receive a full facial rejuvenation effect, using anti-wrinkle injections and dermal fillers. The injection strategy your injector uses, such as the type of filler, volume, delivery, and injection locations, is crucial to getting a good result. Read on to become an educated consumer who fully understands the risks of dermal filler injections and what the top five danger zones are. Therefore, with only cursory research, one might think that, beyond the minor risks, fillers are safe regardless of who is injected.
