Effect of Nerve Ring Block Anesthesia on Lip Edema after Dermal Filler Injection

Abstract

Background and Aim: Due to the good intraoperative environment and its advantages such as rapid recovery, fewer side effects, long-term analgesia into the postoperative period, earlier discharge and reduced costs, regional nerve ring block is an alternative to other anesthetic techniques for procedures to be applied in the lips. In this study, we aimed to determine the effects of nerve ring block anesthesia on lip edema after  dermal filler injection.

Materials and Methods: From January 2017 to June 2018, 72 patients who presented to a plastic surgery clinic desiring filler treatment for lip augmentation were enrolled. The severity and duration of edema and the effect of lip augmentation procedure after the different local anesthetic applications were evaluated in both groups.

Results: Of the 72 patients enrolled in the study, 68 patients completed the study and 2 patients from each group were lost to follow-up. We observed that the severity of edema was less and the transient edema was resolved in a shorter time in group A where regional nerve ring block were performed as a pre-treatment. 

Conclusion: We believe that regional nerve ring block administration before the lip filler procedure may have an impact to reduce the edema occurred in the treatment area due to local anesthetic’s anti-inflammatory effects and neural therapy properties. However, further studies are needed in this respect.
