How Does Radiofrequency Ablation Work?
It begins with a probe needle being inserted into the body at the desired locations. From there, the probe emits waves or electromagnetic radiation consisting of large wavelengths and low frequency, which corresponds to lower energy to heat the desired tissue. The heat eventually destroys the tissue; thus, from a chronic pain standpoint, the nerve can no longer send pain signals to the brain. From a tumor standpoint, it was subjected to heat that killed cells. The procedure itself can take as short as 15 minutes but can take as long as 90 minutes, depending on what is being treated.
During the procedure, the area to be treated is usually numbed with a local anesthetic to minimize discomfort. The probe is carefully guided to the targeted tissue, often using imaging techniques to ensure precise placement. Once the probe is in position, the radiofrequency energy is delivered in controlled amounts, allowing the tissue to be heated to the desired temperature. In chronic pain treatments, this process interrupts the nerve’s ability to transmit pain signals, offering relief. For tumors, the heat can effectively shrink or destroy abnormal tissue. After the procedure, patients may experience mild soreness, but recovery is typically quick, with many resuming normal activities in just a few days.
