Adenoidectomy by a new surgical tool, called FR Coblator is being performed in Jubilee Hospital, Trivandrum, south India By Dr.K.O.Paulose FRCS, Consultant ENT Surgeon.Coblation (cold ablation) is a new technique for adenoidectomy and tonsillectomy.Coblation is a controlled, non-heat-driven process where radiofrequency energy is applied to a conductive medium, which causes a precisely focused plasma field to form around the electrodes. This field is comprised of highly ionized particles.
Since radiofrequency current does not pass directly through tissue during the coblation process, tissue heating is minimal. Most of the heat is consumed by the ionization process. These ions then bombard tissue in their path, causing molecular bonds to simply break apart and tissue to dissolve at a relatively low temperature, typically 40 degrees to 70 degrees Celsius.
