CATALINA PIETROSANU, VIOREL ZAINEA, IRINA IONITA, CRISTIAN DRAGOS STEFANESCU, MURA HAINAROSIE, RAZVAN HAINAROSIE CHEMICAL ABLATION OF THE TISSUE IN ENT SURGERY Various interventions require tissue ablation in ENT surgery. This can be achieved using a multitude of methods, but the tendency today is to use minimally invasive methods. The development of new technologies has allowed us to consider the use of coblation for tissue ablation, which is based on a chemical reaction, instead of a thermal or mechanical ablation. The technology proved to be extremely used in the field of ENT. Its indications range from functional surgery to benign or even malignant tumors and it can be used in the nose, pharynx and larynx, with probes of different length and angulation. This minimally invasive method of tissue ablation associates less scaring, a faster recovery and a lower postoperative discomfort. Although the time required for the intervention may be somewhat longer, the overall results are superior to the classical methods, considering it provides instant hemosthasis as well. We consider it to be a reliable method, fit for a wide range of indications.
