Cannula, cannulas for fillers

What are cannulas?

Cannulas differ from needles in that they do not have a sharp tip, but a closed and rounded tip. The flow of product from the cannula is through an opening located on the side, while in the needle it is through the tip opening.

What are the advantages of using a cannula?

The advantages of using cannulas are related to their length, but mainly to the fact that they have a rounded tip and thus are not sharp. The advantages can be grouped into several basic points:

• Limited entry openings
• Large correction areas
• Reduced injury and pain
• Reduced vascular destruction
• Reduced formation of petechiae
• Astringent effect on the skin

Cannulas come in a variety of sizes, both in terms of length and diameter, choosing the right cannula will depend on the operator, depending on the product used and the area treated.

What does the treatment with a cannula look like?

Using a needle of the same diameter as the cannula, a small hole is made in the skin through which it can be inserted . How to properly administer the product with a filler cannula? First of all, it is important to choose the entry point of the cannula, which should be carried out in a safe, easily accessible place that leaves a good maneuvering space for the cannula itself. Second, it is important to follow the correct plan for inserting the cannula, which must run tightly under the skin. Third, the release of the filler material (hyaluronic acid or other) must be done evenly and in the right amount.

Correct technique

The main indications for filler administration with the cannula are large volumetric facial fillers, and in particular, due to the tightening effect the cannula generates, it finds a proper indication on non-structural facial fragments such as:

• cheekbones
• orbital region
• chin area
• mandibular border

What are the results using a cannula for fillers?

The results obtained with this technique are truly fascinating:

• Volumetric rebalancing of the face, which becomes firmer and rejuvenated
• skin improvement
• Tightening effect, with consistent reduction of skin flaccidity and restoration of facial oval

The resulting effect is very natural.

The special blunt tip of the filler cannula makes insertion under the skin very easy for the specialist and much more comfortable for the patient. The lack of a sharp tip avoids trauma to nerve or vascular tissues in the subcutaneous tissue, which is especially important for use in risk areas such as the mouth and around the eyes (ophthalmoplegia). The cannula's flexible stem allows for "controlled sliding" in subcutaneous tissue and allows for coverage of a larger treatment area with a single insertion. The distal opening allows for even distribution of the filler, which can give a precise result in the shortest possible time. Each cannula comes with a needle to perform skin micropunctures and can give the patient a virtually pain-free experience.

The needle is always larger in diameter than the cannula to be used

• 27G, 30G cannulas require 26G needle
• 25G cannula requires 23G needle for initial puncture
• 22G cannula requires 21G initial puncture needle

4 steps to inject HA (hyaluronic acid) with a filler cannula:

1. Perform micropuncture with the sharp needle provided with each cannula. Tip: to determine the micropuncture site, place the cannula to be used on the skin, calculating the area of application; the entry point must correspond to the proximal tip of the cannula.
2. Insert the flexible microcannula through the previously performed micropuncture, maintaining an angle of 60-90 ° to the skin
3. Insert the cannula into the subcutaneous tissue with gentle movements tangential to the plane of the skin
4. Inject the filler while moving backwards 
5. At the end of the treatment, the treatment area should be massaged to evenly distribute the filler.

Choose the right cannula for each application:

Flexible 22 Gauge Cannula

Special for high-viscosity and high-concentration fillers, for deep treatments to achieve solid volumes.

Flexible 25 Gauge Cannula

Designed for medium to high consistency hyaluronic acid (HA) based fillers and non-hyaluronic acid (non-HA) injectable filler formulations in medium to high depth treatments. Used for most facial procedures in which precise skin filling is required.

Flexible 27 Gauge Cannula

It can be used with hyaluronic acid-based fillers of medium concentration and viscosity.

The 1.5 inch (38 mm) length is the most universal size, commonly used for major facial treatments.

The 2 "(50 mm) cannulas allow coverage of larger areas.

Flexible 30 Gauge Cannula

It is designed for fillers with low concentration and viscosity of hyaluronic acid, used for more superficial injections (especially scars and wrinkles)
