The 5 best danger injection zones for dermal fillers between the eyebrows and just above the nose. It is recommended to use a low-G filler around this region using the serial puncture technique. Lines between the corner of the nose and the mouth. The injection sites with the highest risk were glabella, nasal region, forehead and nasolabial fold.
The three main classic anatomical hazard zones for filler injections referred to in the literature 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 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. It may seem obvious, but all physicians who administer dermal filler injections should have a thorough and practical knowledge of vascular anatomy. The injection strategy your injector uses, such as the type of filler, volume, delivery, and injection locations, is crucial to getting a good result. 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 the keys to successfully injecting dermal fillers.
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. 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. Over the past decade, the use of facial filler injections for minimally invasive rejuvenation has been steadily increasing with a consequent increase in its unpredictable adverse events.
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. The use of facial filler injections has increased dramatically over the past 10 years, as has the incidence of complications. 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.
