Abstract

Electrosurgery is used for intraoral incisions by many clinicians. Much controversy surrounds the effect of lateral heat produced during the electrosurgical incision upon the healing of adjacent connective tissue. Ten electrosurgical incisions were made in the gingiva in each of five adult male volunteers. The duration of incision and actual energy production for each incision were calculated. Excisional biopsies of the incisions were obtained at 0-504 hours. At the light microscopic level, epithelium, totally degenerated immediately following the electrosurgery incision, showed extensive activity at 24-48 hours and had covered all wounds by 72 hours. Early hour specimens showed a homogenous connective tissue region, adjacent to the wound site, devoid of cells and fibers. This zone of denatured connective tissue gradually diminished until it was no longer present at 396 hours.

摘要

许多临床医生使用电外科手术进行口腔内切口。电外科手术切口过程中产生的侧向热对相邻结缔组织愈合的影响存在诸多争议。在五名成年男性志愿者的牙龈上各进行了十次电外科手术切口。计算每次切口的持续时间和实际能量产生量。在0至504小时获取切口的切除活检样本。在光学显微镜水平下，上皮组织在电外科手术切口后立即完全退化，在24至48小时显示出广泛的活性，并在72小时时覆盖了所有伤口。早期样本显示，伤口部位相邻的结缔组织区域均匀，没有细胞和纤维。这个变性结缔组织区域逐渐缩小，直到在396小时时不再存在。
