Introduction: Four-megahertz radiowave surgery is a relatively new technology usage of which rapidly expands reaching superior results compared to other surgical techniques. Radiosurgery is an atraumatic metod of cutting and coagulation of soft tissues that uses optimal low heat 4.0 MHz source for numerous plastic,esthetic and cosmetic interventions which reguires surgical precision, penetration control and low temperature. This technology allows us to simultaneously cut and coagulate the tissue with minimal lateral tissue alteration, without burning damage and with better wounds healing.This mode is used by the author in high vascularity anatomical areas and for the deeper tissue of the head and neck. The pure cutting wave-form is ideal for skin excision with otoplasty and blepharoplasty when we expect ideal esthetic result. Coagulation is obviously paramount for any surgeon and can make the difference between a good and poor result. When he coagulates tissues in the head and neck, the surgen is frequently close to significant structures such as nerves and vessels which we must protect. Ellman Sugitron 4.0 offers great advantages. One of the stronges point of the Ellman system is the large array of specialized electrodes. By bending the malleable electrodes we can use them at any angle or even around corners. Material and Methods: The Author has done surgical procedures on over 600 patients using this technique on different esthetic problems with satisfying results. In operative material dominate various skin growths (hemangioma, fibroma, naevus, wart) blepharoplasy, otoplasty, rhinoplasty and other minor surgical procedures. Interventions were done in local anesthesy. The aim of this work is to present our observations about radioablation in heterogenous pathological process on head and neck based of our own experience. Results: Our results show that this technology have great advantage over other techniques (scalpel, electrocouter, laser) from which the most important are simultaneous cutting and coagulation,coagulation in liquid medium, minimal termal damage of latteral tissues, faster healing of wounds with excellent cosmetic results. If we want surgery without cut,cut without scar, Ellman Sugitron is the best choice.

A radio-frequency wave is normally incident upon an inhomogeneous plasma slab. The plasma slab is composed of partially ionized high-temperature air corresponding to the characteristics of the plasma sheath surrounding hypersonic reentry vehicles. The isotropic part of the electron velocity distribution function is Maxwellian because of electron–electron collisions. The electromagnetic wave is intense enough to heat selectively the electron gas, altering the various electron production and loss processes. The high-frequency limit is considered, and expressions are obtained for the electron number density and effective collision frequency as a function of electron temperature. The effective collision frequency takes into account the effects of electron–neutral and electron–ion collisions for momentum transfer. From an energy balance equation, the electron temperature is found to be a function of both the frequency and field strength of the wave. The electron temperature is found also to exhibit an instability that gives rise to a hysteresis effect.
