Jawline Filler Cannula Technique

The jawline is an important part of the facial contour. Many people pursue a clear and smooth jawline because such a jawline can give the face a more three-dimensional structure, making the face more three-dimensional and charming. In aesthetic standards, a delicate and clear jawline is often associated with a young and healthy image.

However, with age or weight gain, the increase in soft tissue and fat will lead to blurred jawlines, and even double chins and sagging facial contours.

In medical beauty, there are many ways to correct the jawline, such as Botox to thin the face, thread lifting to lift the face, and the use of fillers to create a perfect jawline.

Fillers such as hyaluronic acid (HA) filling have become a common solution for shaping the jawline. In terms of filling technology, the blunt cannula filling technique (Cannula Technique) has gradually replaced the traditional sharp needle injection due to its characteristics of less trauma, fast recovery and high safety. More and more operators have begun to use and love it, becoming a method that doctors and beauty seekers prefer.

Principle of Cannula Technology

Blunt cannula filling technology (Cannula Technique) uses a flexible blunt micro cannula tube to accurately and evenly inject fillers into the target layer through a small number of injection points to achieve the purpose of supporting facial tissue and improving the jawline contour.

Blunt cannulas have good flexibility. After insertion, the injection angle can be adjusted back and forth to perform injections in a larger range around the injection point to complete the filling task.

1. Advantages of Blunt cannulas

Compared with traditional sharp needle injection technology, Blunt cannula filling technology has the following obvious advantages:

Reduce vascular damage: Blunt cannulas will not easily puncture blood vessels, so the risk of vascular embolism can be greatly reduced, making the operation safer.

Reduce postoperative bruising and swelling: Due to less vascular damage, the recovery time after filling is shortened, avoiding severe postoperative bruising and swelling.

Reduce pain: Compared with the discomfort caused by multiple injections of sharp needles, Blunt cannulas can reduce the number of injections and reduce the pain of patients.

The filling effect is more natural: Since the Blunt cannula can slide within the tissue layer, the doctor can more accurately control the distribution of the filler, making the filling effect more uniform and natural.

Advantages and Disadvantages of Filler for the Jawline

Applicable to the following:

• People with blurred jawline contours who want to shape clear lines through filling.
• Mild to moderate facial sagging, need to improve the supporting structure through filling to restore youthful state.
• Those who want to improve facial fullness due to loss of soft tissue or fat at the jawline, resulting in facial depression and enhanced bone sense.
• Those who pursue a delicate V-face effect and want to create a more distinct facial contour.

2. Contraindications

Not everyone is suitable for jawline filling. The following people are not recommended to undergo this project:

• People who are allergic to filling materials may have severe allergic reactions.
• People with coagulation disorders or those who are taking anticoagulants are prone to bleeding problems.
• People with facial infections, inflammation or skin lesions, such as acne, eczema, etc., should avoid injections to avoid aggravating the condition.
• Pregnant or breastfeeding women are advised to postpone the filling treatment to ensure the safety of mother and baby.

Operation Steps of Blunt Cannula Injection at the Jawline

1. Preoperative evaluation

Face analysis: The doctor will conduct a professional evaluation of the patient's jawline, including the degree of skin laxity and bone structure, to determine the specific filling plan, such as where to insert the blunt cannula, where to inject the filler, how much filler to inject, and subsequent massage and adjustment.

Choose the right filler: The texture of different fillers, the doctor will choose the most suitable material according to the patient's needs. Or choose the right filler according to the patient's consumption ability.

Personalized design plan: The doctor will design a reasonable filling method according to the patient's face shape and expected effect to ensure overall facial coordination.

2. Preoperative preparation

Mark the injection point: Mark key positions such as the mandibular margin and mandibular angle to ensure the accurate distribution of the filler.

Disinfect the skin: Use iodine or alcohol for strict disinfection to avoid the risk of infection.

Local anesthesia: Lidocaine anesthesia is usually used to reduce discomfort during the injection process.

3. Cannula technique

Single-point insertion: Doctors usually choose the mandibular angle or the vicinity of the earlobe as the insertion point to reduce skin trauma.

Creating a channel: First, gently puncture the epidermal opening with a sharp needle, and then use a blunt cannula to enter the subcutaneous tissue layer.

Precise layered filling:

• Deep injection (above the periosteum): Provides the main support and enhances the jawline contour.
• Mid-layer filling (deep dermis): Increases smoothness and makes the transition more natural.

Slowly push the filler while withdrawing the cannula to ensure that the material is evenly distributed.

Shaping adjustment: The doctor will use manual shaping to make the filler fit the tissue naturally and optimize the final effect.

Advantages of Diaminy Cannula in Jawline Filling

As a high-quality blunt cannula filling tool, Diaminy Cannula has the following five advantages in jawline shaping:

Higher flexibility: Diaminy Cannula is made of stainless steel, which has excellent flexibility, so when injecting, the injection angle can be adjusted at will, so that it can slide smoothly in the subcutaneous tissue layer to reduce tissue damage.

Fewer insertion points: Due to its superior sliding ability, Diaminy Cannula allows doctors to complete large-area filling with fewer insertion points, reducing injection pain and improving patient comfort.

Reduce the risk of vascular damage: Its blunt head design is more optimized than traditional needles. The cannula is a bullet-shaped blunt cannula, which will not puncture blood vessels during insertion, ensuring the safety of injection and reducing injection side effects.

Precise filler distribution: The inner wall design of the Diaminy Cannula can release filler more evenly. It makes the filler distribution more even, bringing more natural results and smoother jawline shaping.

Compatible with multiple filler materials: Diaminy cannula is suitable for various types of fillers, such as hyaluronic acid, poly-L-lactic acid and calcium hydroxyapatite. Doctors can freely choose the most suitable filling solution according to the patient's needs to ensure the best shaping effect.

How to avoid jawline filling errors

When performing jawline filling, doctors need to ensure the filling is safe and effective. The following are key measures to avoid filling errors:

1. Evaluate the patient's facial structure Before treatment, doctors should conduct a detailed analysis of the patient's jawline to avoid over filling.

2. Choose the right filler Different filler materials have different textures and molecular sizes. Doctors should choose the most suitable filler based on the patient's facial features.

3. Master the correct filling level Filling effects vary at different anatomical levels. Generally speaking, filling should be located above the periosteum to provide optimal support.

4. Avoid overfilling Overfilling not only causes facial disproportion, but may also cause local swelling.

5. Control the uniform distribution of fillers When using a blunt cannula for filling, the filler should be pushed slowly.

Postoperative Care and Precautions of Jawline Filler Cannula Technique

1. Postoperative care

• Try not to press: Avoid touching or massaging the filled area within 24 hours after surgery to prevent the filler from shifting.
• Reduce facial movement: Avoid opening your mouth widely and chewing hard food to avoid affecting the shaping effect.
• Appropriate ice pack: ice packs can be used for short periods of time in the early postoperative period to reduce swelling and bruising.
• Keep the injection site clean to avoid infection, and avoid using cosmetics within 48 hours after surgery.

2. Possible adverse reactions and treatment

• Mild swelling and bruising (dissipates within 1-2 weeks): anti-bruise ointment can be used to relieve it.
• Asymmetry or nodularity: It usually improves on its own within a week, and if it persists, it can be adjusted after a return visit.
• Delayed inflammatory reaction (very rare): Take oral anti-inflammatory drugs if necessary. Follow the doctor's instructions.
• Risk of vascular embolism (very rare): If symptoms such as pale skin and severe pain occur, the filler should be dissolved immediately and medical treatment should be sought in time.

Conclusion

Jawline filler cannula technique is currently one of the safer and more effective methods for jawline shaping.

Compared with sharp needle technology, Blunt cannula reduces bleeding, bruising and postoperative pain, and has a shorter recovery period.

However, to ensure safety and effectiveness, doctors need to have solid and rich filling experience and accurately control the filling level and dosage to achieve the most ideal facial shaping effect.
