Abstract
Bipolar radiofrequency (RF) is capable of delivering higher energy fluencies direct to the dermis through a needle electrode. This produces heat when the tissue electrical resistance converts the electric current to thermal energy in the tissue. A 38-year-old man visited our clinic for reduction of submental fat deposit, but otherwise in overall good health. After deciding to perform phosphatidylcholine (PPC) injections subcutaneously, we concerned about edema and swelling of injection site lasted several weeks. We wanted to shorten the period of edema and swelling, and we decided to add bipolar RF treatment. After 1 week of PPC injection combined with RF treatment, overall volume of jowl was decreased and edema and swelling on the PPC injected site markedly subsided. This reduction of fat deposit lasts longer than 1 year. Follow-up for 1 year demonstrated that the cosmetic results were well maintained.
