It is crucial for doctors and patients alike to know the areas of the facial region to avoid injecting dermal fillers. This is to prevent fatal complications that could potentially cause harm to the patient. These regions include:
Between the eyebrows and just above the nose
It is recommended that you use a Low-G filler around this region using the serial puncture technique. This is because this region is home to the supraorbital and supratrochlear arteries. Medical practitioners are advised to use digital pressure to prevent backflow in the event of inadvertent injection of the vasculature.
Temple area
Injecting dermal fillers into the temple area makes it easier to regain a more youthful look. It is important to note that if your dermatologist/plastic surgeon lacks the proper skill or uses an improper injecting technique, the procedure may result in serious consequences. Consequences can also arise from the use of wrong filler products. These consequences include:
- Bruising
- Swelling
- Chewing discomfort
- Overcorrection problems
- Skin infections
- Intravascular necrosis
- Potential Blindness
Lines between the corner of nose and the mouth
This region is referred to as the nasolabial grooves. It is close to the facial artery and it runs close to the surface of the skin. Dermal fillers should be injected deep into the dermis as restricting the blood flow of this blood vessel could result in skin damage. Restricted blood flow could also lead to damage to the tip and side of the nose.
Infraorbital region
Overall, when injecting deep into the mid-face, measurements should be kept in mind to avoid intravascular cannulation or vascular injury. Avoid direct deep injections into this area, going just lateral. Medial injections should be avoided completely. Migraines and blindness are some extreme risks that may occur in case of injection errors in the area.
Nasal Augmentation
When injecting dermal fillers into the nose, the injections should be carried out deep into musculoaponeurotic layers. One could also target the pre perichondrial and preperiosteal layers to avoid injury or cannulation of vessels. The vasculature in the nose is superficially located beneath the dermis.
