A study was designed to document heat production subjacent to tissue excision by electrosurgery. In Phase I of the study, 20 electrosurgery excisions were made with a loop electrode in the palatal mucosa of miniature swine. Subjacent heat production was measured with implantation thermistors. Temperature measurements adjacent to 20 single incisions made with a needle electrode were used for comparison. Energy used and duration of active electrode contact with the tissue were recorded for each procedure with an electronic measuring device. In Phase II, 20 sets of excisions consisting of three successive excisions were performed. The following intraexcisional cooling periods were used for four sets each: 1 second, 5 seconds, 8 seconds, 10 seconds, and 15 seconds. Results indicate that single electrosurgery excisions with a loop electrode generate more energy than incisions made with a needle electrode. Subjacent heat production, however, is not significantly different. Cooling intervals of at least 15 seconds between successive electrosurgery excisions made with a loop electrode are necessary to prevent heat build-up of a magnitude capable of initiating destructive alveolar changes.
一项研究旨在记录电外科手术切除组织下方的热量产生情况。在该研究的第一阶段，使用环形电极在小型猪的腭黏膜上进行了20次电外科切除。通过植入热敏电阻测量下方的热量产生。使用针电极进行的20次单一切口附近的温度测量用于比较。使用电子测量设备记录每个手术过程中使用的能量以及电极与组织的有效接触持续时间。在第二阶段，进行了20组由三次连续切除组成的切除。以下切除内冷却时间每组各使用四次：1秒、5秒、8秒、10秒和15秒。结果表明，使用环形电极进行的单次电外科切除比使用针电极进行的切口产生更多能量。然而，下方的热量产生没有显著差异。在用环形电极进行连续电外科切除之间，至少需要15秒的冷却间隔，以防止热量积聚到能够引发破坏性牙槽变化的程度。
