In this article, we will share the advantages and disadvantages of curved injection needles, applicable parts and precautions during operation

➤ Advantages of curved needles:

1. Provides greater flexibility and control for better manipulation of injections.
2. Curved needles allow for better angles when the injected area needs to avoid certain sites or follow a specific curved shape.
3. For some specific maneuvers, such as vertical injection of the lips, the curved needle can better follow the curve of the lips.
4. If there is a bent needle, the operator does not have to move the needle too much to adapt to the shape of the injection area, which can reduce the workload.

➤ Disadvantages of bent needles:
1. Bent needles may require increased Extrusion Force, and with some viscous products, injectors may notice this change.
2. A bent needle may have weakened the needle somewhat, which could be a risk if the needle breaks during an injection. But in most cases, the risk is very small as long as the needle is not inserted into the bend.

3. When you start out with bent needles, you may forget that rotating your hand changes the position of the needle, because rotating a straight needle doesn't change its position, but rotating does change the position of the needle once it's bent. Therefore, great care must be taken with the placement of the needle, not just the orientation of the syringe.

➤ Curved needles are for areas that need to be avoided or follow a specific curved shape, including but not limited to:
1. Nose Tip: The curved needle provides a better angle when it is necessary to address the small V shape of the nose tip or to make the nose tip more pointed.
2. Lips: When performing vertical injections on the lips, the curved needle follows the curve of the lips better.
3. Jaw angle: If the patient's shoulder position makes injection into the mandibular angle difficult, a curved needle can help accommodate the shoulder position.

➤ Operation Precautions:
1. Determine the direction of the knife edge: Before bending the needle, you need to determine the direction of the knife edge. Usually we want the knife edge to face up, but sometimes it may face down.
2. Avoid injecting beyond the crease: To prevent needle breakage during injection, avoid inserting the needle beyond the bend.
3. Control of injection depth: During the injection process, it is necessary to adjust and control the injection depth according to the bending angle of the needle, and keep sliding at the correct depth.
4. Pay attention to the position of the needle tip: Once the needle is bent, the rotation of your hand will change the position of the needle tip, so you need to always pay attention to the position of the needle tip, not just the direction of the syringe.
5. Attention to care and cleaning: When using bent needles, they should be kept clean to prevent infection.
6. Choice of product: For some products that are viscous or difficult to inject, a bent needle may increase the difficulty of injection, so this should also be taken into account when choosing a product.
