Nasolabial folds are a normal part of the human anatomy. Usually, it is not considered a medical condition or a sign of aging. However, some people undergo cosmetic surgery in order to reduce the appearance of the nasolabial folds or remove them.
These procedures include the use of dermal fillers. Fillers are implants placed under the skin to fill the nasolabial fold area to fill and reduce the appearance of wrinkles. Also, lift the cheeks in the upper cheek area to make the nasolabial folds less noticeable.
Dermal Filler Injection is a great challenge for doctors because it is injected in the very fragile area of the facial artery. Because there are so many changes in the anatomy of the facial artery, it is difficult to know the location of the artery or its branches with the naked eye.
If a dermal filler is injected into an artery or its branches, it can impede the supply of oxygenated blood to the skin and can reach even more of the blood supply to the retina of the eye, causing blindness in extreme cases.
For example, the Portable Infrared Vein Finder: Vdetector-P3 is very suitable for this program. It helps to visualize the location of the facial veins. Especially, it has a stent that can support the vein viewer to fix on the patient’s face. In this way, the surgeon’s hands can be completely free, while having a very clear map for up to 4 hours.
