[Effect of high frequency application on the tongue base. In vitro results of "radiofrequency application" on the porcine tongue base].

Background And Objective: A newly developed radio-frequency monopolar needle electrode was evaluated in vitro on porcine tongues.

Patients And Methods: Porcine tongues with different tissue temperatures (20+/-1) degrees C and (32+/-2) degrees C were coagulated for 90 s. In a second step, 23 coagulations at 7 W were applied (34+/-2) degrees C.
