Radiofrequency Energy for Denervation of Selected Facial Muscles: Clinical Experiences at Six Months

Abstract

The goal of treatment with a unique, bipolar radiofrequency (RF) ablation device is to provide the surgeon with a minimally invasive and neurotoxin altrernative, percutaneous approach to glabellar frowning. Therapeutic RF energy delivered via the probe tip area produces thermal effects that inhibit the designated nerve and produce selective conduction block. In our prospective study, significant glabellar frown reduction was immediately achieved in 80% of patients (40). All 40 of these patients maintained significant results at the 3-month time period, and 78% at the 6-month time period. Bruising and swelling were seen in 6% and 92% of patients respectively, mostly during the first week and resolving within two weeks. The cohort continues to be followed for longer term follow up. Further studies will help determine mass market viability of thermal deneveration as an alternative to injectable nerve paralytic agents.
