摘要：

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+/-1degreesC and 32+/-2degreesC) were coagulated for 90 s. In a second step, 23 coagulations at 7 W were applied (34+/-2degreesC). Results. The volume of the lesion correlated well the lesion was 507 mm(3) (100+/-15%). Prolonged energy application did not correlate with a larger volume of the lesion. Conclusion. The new radio-frequency needle electrode can reduce tongue volume in a precise and controlled manner (SD+/-15%).
