retains its leading position in the list of the most requested injection procedures. Often the success of this procedure depends on the doctor's ability to determine the ideal proportions for a particular patient. However, there is no single technique for introducing a dermal filler, and each practitioner uses their own approach to achieve the desired results.
As for the perioral instrument,
cosmetician Jackie Partridgebelieves that its choice depends on the clinical case in question, but notes that the cannula still has a number of advantages. Benefits of cannula correction of the perioral zone
Although dermal fillers are traditionally injected with a pointed needle when working in the perioral area, the following advantages of cannula correction are worth noting:
• less bruising;
• less painful procedure;
• shorter recovery period;
• higher safety profile (reduced risk of intravascular injection, infections);
• better maneuverability;
• fewer insertion points.
Successful correction of the perioral zone with cannulas: general recommendations
When working with the lips and the area around the mouth, as in the case of any aesthetic procedure, one of the key conditions for the effectiveness and safety of the correction is knowledge of anatomy. In particular, the practitioner must be aware of the location of the inferior and superior labial arteries and be aware that their exact location may vary. Therefore, before administering the drug, the author always finds these vessels by palpation.
The use of aseptic technique is equally important, as injection procedures always carry the risk of infection.
Important aspects of lip augmentation: not only size matters The entry point of the cannula is usually located slightly lateral to the corners of the mouth, the author injects the product into the deep layers of the dermis.
When working in the correct plane, the cannula moves freely, and the maximum that the patient feels – slight discomfort.
Each insertion plane has its own characteristics: the adipose tissue is very smooth, while in the more superficial layers, a certain resistance is felt during insertion. When working in the correct plane, the cannula moves freely, and the maximum that the patient feels – mild discomfort.
How to choose a cannula for perioral correction
The author prefers to use a 38 mm cannula, which is slightly longer than a standard 25 gauge needle. Such an instrument provides access to the midline of the perioral region or lips from a point slightly lateral to the corner of the mouth.
Despite all the advantages of cannula correction of the lips and the area adjacent to them, there are cases when it is still better to use a needle for the introduction of dermal filler. Based on my own experience, the author notes that the needle provides a more accurate injection of the drug.
Another disadvantage of using a cannula for correction is its cost, since the needle is often included in the kit purchased by the doctor, unlike the cannula. Of course, the safety of patients is always in the first place, because such costs, according to the author, are fully justified.
Many patients prefer cannula correction for several reasons: less bruising, less risk, and a shorter downtime than needlework.
The choice of instrument for perioral correction depends on the chosen technique, product and patient.
Effective correction of the perioral zone: what shortcomings should be eliminated It is well known that many patients prefer cannula correction for several reasons: less bruising, less risk, and a shorter downtime than with needle work.
The success of the lip correction procedure with fillers largely depends on the knowledge and experience of the doctor, the correct choice of products and injection techniques, as well as taking into account all the wishes and individual characteristics of the patient.
