Cannula – what is it?

Hollow tubes with a side hole are called cannulas. They have a blunt end, unlike conventional needles, which lessens pain for the patient and helps prevent damage to soft tissues. The cannula spreads and bends around the vessels without harming them because of its flexibility.

French plastic surgeon Bernard Herzog first proposed the concept of flexible blunt-tipped needles in 2009. Plastic surgeons started using the first cannulas to remove fatty tissue. Their benefits were later recognized in the field of cosmetology as well.

Cannula – application in cosmetology and contour plastic surgery

The use of cannulas in contour plastic surgery and cosmetology is relatively new. Cosmetologists observe that facial contours appear more natural when utilizing a cannula.

Its flexibility allows for the least amount of punctures during the procedure and the most accurate administration of the injection.However, experts claim that cannulas cannot fully replace needles in a given situation. It is done with a needle because the blunt end prevents it from puncturing the skin. In situations where an injection near the skin or with a stroke is required, it is also utilized.

In cosmetology, cannulas are used for skin hydration injections, age-related changes removal, and facial oval equilibration. Cannulas are used in contour plastics procedures to smooth out deep wrinkles, increase and correct specific areas, and eliminate flabby skin on the face, neck, and décolleté.

Advantage of a cannula – which is better: needles or cannulas

Flexibility is a cannula’s primary benefit. This feature enables it to effortlessly navigate subcutaneous obstacles without compromising their integrity.

Cannulas lessen the chance of bruises and swelling, which is significant because cosmetology places a high value on appearance. Cannulas, as opposed to conventional needles, enable the most precise dispersion of the material beneath the skin. This allows cosmetologists to create the most natural-looking contours possible.

Cannula-assisted injections are thought to be the safest, according to medical professionals. It is ideal for operations performed in difficult-to-reach and delicate areas, like the neck, whisky, cheekbones, nose bridge, and vicinity of the eyes.

With only a few punctures required for rejuvenation using a cannula, the process is nearly painless and takes less time to heal.

When comparing cannulas to needles, there are several advantages for the former. However, cosmetologists prefer to use needles for some injections. These consist of drawing thin or dashed lines and lip correction.

REMARKABLE FACT 90% less chance of bruising and swelling occurs with cannulas. It only takes a few days to recover.

Disadvantages

Although the cannula has a long list of benefits, it also has some drawbacks. Among them are:

1. High qualification requirements for a specialist. The procedure for injections with a cannula, compared to a needle, is much more complicated, so the doctor must undergo preliminary training. A specialist must have an idea of ​​the basic location of important vessels and be able to work on sensitive areas of the body.
2. High material consumption. On average, the volume of the substance used increases by 15%. This is a significant disadvantage, given the high price of cosmetics.
3. Increase in the cost of the procedure. In most cases, the drugs are dispensed ready-made. A regular needle is included in the kit. Cosmetic centers have to buy cannulas separately, and this leads to an increase in the cost of injections. Many patients do not agree to additional costs.
4. Contraindications. Cannulas are not prescribed in cases where the client is doing the procedure again, and the first injection was made with a needle. This is due to the fact that the needle disrupts the integrity of the tissues and during healing, micro scars are formed, through which it will be difficult for the cannula to pass.

In cosmetology and medicine, a cannula is a thin, flexible tube used for precise, minimally invasive procedures. It makes it possible to administer treatments like fillers in a safe and efficient manner, lowering the possibility of swelling and bruises and guaranteeing smoother outcomes. Comprehending the function of a cannula can assist you in making well-informed choices regarding medical and cosmetic procedures.

How to use cannulas – cannula operation

Cosmetologists concur that cannula procedures should only be carried out by qualified specialists.

Algorithm for procedure:

1. Marking the area to be treated and applying puncture points.
2. Disinfection and pain relief.
3. Preliminary puncture with a sharp needle.
4. Insertion of the cannula. In this case, the skin is stretched in the opposite direction from the movement of the needle.
5. Injection of the drug.
6. Massage of the treated area for the correct distribution of the substance.

When is it better to use regular needles

Although they are frequently used in contour plastic surgery, cannulas are not suitable for all procedures. The needle enables thin, precise injections, and the cannula is made for uniform, linear drug injections. Because of the cannula’s thick tip, piercing the skin near the surface is not possible.

Cosmetologists advise using a standard needle to adjust lip shape instead of a special one. The use of a needle is also suggested when the patient needs to remove wrinkles or fill in small scars.

The cost of the procedure goes up because cannulas are more expensive than needles.

Certain cosmetologists are not authorized to use cannulas. Furthermore, there may be circumstances in which a patient should not use a cannula.

With good reason, the cannula is seen as the wave of the future for cosmetology and contour plastic surgery.

In turn, the needle comes in handy when precise work is required. When the cannula and needle are used together, the outcome is perfect.

In both cosmetology and medicine, cannulas provide a safer and more efficient method for a variety of procedures. Patients will find treatments more comfortable because of their blunt tip and flexibility, which lowers the possibility of bruises and tissue damage.

The cannula has shown to be an effective tool for delivering medications and fillers, allowing for precision and minimizing side effects. Because of its adaptability, it will probably always be a major factor in improving aesthetic and medical procedures.
