Argon plasma coagulation (APC) surgery in otorhinolaryngology

The Argon Plasma Coagulation (APC) technique has been used with success in open surgery and endoscopy for hemostasis and thermal devitalisation of pathological tissue. We developed techniques and instruments for the use of this technique in Otorhinolaryngology, because of its excellent hemostatic effects and devitalising properties. APC surgery is based on a monopolar high-frequency (HF) electrical current transmitted through ionized argon gas from the tip of an applicator to the tissue surface in a contact-free mode. Indications for the use of this technique include hyperplasia of the inferior turbinate in nasal obstruction, recurrent epistaxis in hereditary hemorrhagic telangiectasia, leukoplakia of the mucosa, recurrent respiratory papillomatosis (RRP) of the lower airway, in combination with flexible systems. A combined technique of blunt dissection and plasma coagulation has been designed for bloodless removal of the tonsils. This new technique offers a wide variety of advantages. The limited penetration depth makes APC surgery a safe procedure; damage to neighbouring tissue can be avoided. The APC technique is a useful and comparable inexpensive method to achieve devitalisation of tissues and easy to handle hemostasis.
