摘要/Abstract

摘要： 目的利用CT三维重建技术研究隧道法射频对离体猪舌的损伤容积,探讨隧道法射频作用点的选择。方法 9只新鲜离体猪舌随机分成三组,每组3只。对三组猪舌采用不同的射频参数,每组3只猪舌采用不同的作用点。用低温等离子射频发生仪进行射频操作。作用前后分别将猪舌进行CT扫描并三维重建,并对损伤区域进行容积计算。结果相同能级和作用时间下,不同作用点射频损伤容积无统计学差异; 作用10 s时,射频损伤容积随能级提高而增大; 能级为6时,射频损伤容积随作用时间延长而增大。结论舌根隧道法射频治疗在一定的参数设置范围内,随着能级提高损伤容积随之增大,随着作用时间延长损伤容积亦随之增大。

Abstract: Objective To investigate tunnel radiofrequency (RF) volumetric reduction of porcine tongue by computed tomography (CT) 3D reconstruction and explore better RF points. Methods Nine fresh porcine tongues were randomly divided into 3 groups, with 3 in each group. The 3 groups were set to different RF parameters, and 3 porcine tongues of each group were designed 3 RF points respectively and RF operation was done with RF generator. CT scan and 3D reconstruction were performed before and after RF, and volumetric reduction was calculated. Results With the same level and RF time, there was no significant difference between different RF points. When RF time was 10 s, volumetric reduction increased with the increase of the energy level, and volumetric reduction increased with the increasing of RF time when the energy level was 6. Conclusion Within certain parameter range of tunnel RF, volumetric reduction increases with the raise of energy level, along with the RF time extension volumetric reduction also increases.
