摘 要:目的通过观察活体内Carnoys液处理牙源性角化囊肿的囊壁变化探讨其治疗机理材料和方法选择临床和X线诊断为牙源性角化囊肿的病例28例术中打开囊腔吸净囊内容蘸取Carnoys液涂布在囊壁表面20min后切取囊壁作组织学、组织化学、酶组织化学。Objective: The aim of the present study is to investigate histomorphological change of keratocyst after spreading cyst walls with Carnoy's solution.Materials and Methods:28 consecutive cases clinically and radiographally diagnosed as keratocysts were employed.The cysts' walls and removal of content were carried out sequentially.The cyst walls in vivo were spread with Carnoy's solution for 20 minutes.Then cauterized and uncauterized specimens of cysts were excised and evaluated histologically,histochemically,enzyme histochemically and ultrastructurally.Results:The decline of elasticity and ready removal of cysts' walls were noticed.Disruption and disintegration of overlying epithelium and loss of the activity of acid phosphatase were observed.Disarrangement and disconnection of collagen fibers were revealed.Conclusions:This study suggests that management of cysts walls with Carnoy's solution during an enucleation procedure may destroy cystic tissues.
