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.
RESULTS
The volume of the lesion correlated well with increasing temperature. In step two, the mean energy was 238 J and the mean volume of 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%).
背景与目的
在猪舌上对新开发的射频单极针电极进行体外评估。
患者与方法
将处于不同组织温度（20±1）℃和（32±2）℃的猪舌进行90秒的凝固处理。第二步，在（34±2）℃下以7瓦功率进行23次凝固处理。
结果
病变体积与温度升高密切相关。在第二步中，平均能量为238焦耳，病变平均体积为507立方毫米（100±15）%。延长能量施加时间与更大的病变体积无关。
结论
新型射频针电极能够以精确且可控的方式（标准差±15%）减小舌体积。
