INTRODUCTION TO RADIOSURGERY
Surgery that is performed with modern radiosurgical equipment should not be confused with the results obtained
with electrocautery, medical diathermy, spark gap generators, or partially rectified devices that do not provide
surgical cutting waveforms. Thus, before reviewing the instructions and clinical use, a brief definition of
radiosurgery and of the radiofrequency waves that produce this phenomenon may prove helpful.
Radiosurgery is an atraumatic method of cutting and coagulating soft tissue, without the post-op pain and tissue
destruction of electrocautery. The cutting effect, known as electrosection, is performed without manual pressure
or crushing tissue cells. It results from heat generated by the resistance the tissues offer to the passage of a
radiofrequency wave, which is applied with a fine wire called a surgical electrode. The heat disintegrates and
volatizes the cells in the path of the waves. This causes the tissue to split apart as though it had been cut with a
razor-sharp knife. Electrocoagulation is a nonvolatilizing destruction of tissue cells by a radiofrequency wave.
The atraumatic nature of electrosection provides a noteworthy advantage. The lack of trauma results in tissue
healing without fibrous contractile scar tissue, which characterizes healing of wounds created by manual cutting.
Radiosurgery, as a result of these advantages, facilitates, accelerates, and improves surgical procedures
tremendously. It also helps to eliminate the unfavorable post-operative sequelae such as swelling, infection, and
postsurgical shock from excessive blood loss, that are so often experienced after “traditional” instrumentation for
comparable surgery.
