While post-procedure responses can vary, the ThermiRase patient should expect some swelling in the treatment area for a couple of days. The injection site will heal in a few days without scarring like any skin puncture. In the peer-review study that used ThermiRase protocols, 78% of patients had relaxation that lasted more than12 months. So 22% had results lasting a shorter time, meaning there is some variability from patient to patient.
A small device called a Peripheral Nerve Stimulator is first used to map out the path of the nerve with small marks on the top of the skin. When the PNS is placed on the skin immediately above the nerve the muscle twitches and that point is marked, A series of these points marks the path of your nerve under the skin. Numbing medicine is placed where a hollow needle called a cannula is inserted and placed along the path of the nerve, which is re-stimulated to confirm correct placement. Then more numbing medicine is pushed through the cannula directly onto the nerve. The ThermiRase system is set to deliver a temperature of 85C for a period of 60 seconds. As energy is applied the patient begins to feel increasing temperature at the treatment location but at the 30 second mark the sensory bourbons become dormant and the patients feels very little. This process is repeated along the pathway of the nerve until a number of thermal lesions have been created and the nerve function is disabled.
The treated area will be a bit tender and edematous or swollen for one to three days. Your surgeon can recommend medicine or therapy to minimize this effect. Normal activity can be resumed immediately.
