The size of the needle used for Platelet-Rich Plasma (PRP) injections varies depending on the technique and area being treated. Based on the provided reference, here’s a breakdown:
Needle Sizes for PRP Injections
| Needle Gauge | Description |
|---|---|
| 25 or 27 gauge, 1.5” cannula | Used with a fanning technique for injecting into the problem area. |
| 30-31 gauge | Used for intradermal bleb injections. |
Here's a more detailed explanation of how needle selection impacts PRP treatment:
-
Fanning Technique: The 25 or 27 gauge, 1.5” cannula is often used for a fanning technique. This involves injecting PRP in a series of shallow, overlapping passes in the treatment area. It allows for even distribution of PRP.
-
Intradermal Blebs: For intradermal injections, a finer gauge like a 30 or 31 needle is preferred. The injections create small "blebs" just under the skin, which can be effective for certain conditions, like hair restoration.
-
Syringe Size: The reference notes the use of a 1 cc syringe for injecting PRP.
Key Takeaways:
- Different needle sizes cater to different injection techniques.
- 25-27 gauge needles are used for fanning.
- 30-31 gauge needles are used for intradermal blebs.
It is important to note that the specific needle size may be chosen by the practitioner depending on the area of treatment, patient comfort and desired results. The reference also indicated that typically 3-4 treatment sessions are needed within 4-6 week intervals for optimal results.
