Summary
A new microdroplet technique using an insulin syringe facilitates precise injection of Silikon 1000 for facial rejuvenation. This method ensures accurate dosing, preventing complications like silicone migration and granuloma formation.
Area of Science:
- Dermatology
- Plastic Surgery
- Medical Device Technology
Background:
- The Food and Drug Administration (FDA) approved Silikon 1000 for intraocular use.
- Off-label use of Silikon 1000 as a soft-tissue filler for facial rejuvenation is increasing in the U.S.
- Microdroplet technique is crucial for preventing adverse effects like silicone migration and granuloma formation.
Purpose of the Study:
- To present an accessible method for injecting viscous silicone oil (Silikon 1000) using the microdroplet technique.
- To utilize an inexpensive and readily available syringe and needle for this procedure.
Main Methods:
- The study proposes using a Becton Dickinson 3/10 cc insulin U-100 syringe for Silikon 1000 injection.
- This syringe allows for precise measurement of microdroplets (0.01 mL or 0.005 mL).
- A method for easily filling the syringe with viscous silicone oil is described.
Main Results:
- The Becton Dickinson 3/10 cc insulin syringe facilitates precise injection of minute Silikon 1000 amounts.
- Clearly marked, widely spaced calibrations on the syringe ensure accurate measurement.
- The technique minimizes the risk of overinjection, even with the smallest volumes.
Conclusions:
- Sequential microdroplets of 0.01 cc or less of Silikon 1000 can be accurately measured and injected.
- This precise method enhances ease of use and helps avoid inadvertent overdosing.
- The technique aids in preventing complications associated with silicone injections for facial defects.
