本研究的目的是评估饱和盐液防腐身体在口腔外科手术技能培训中的有用性。在东京医科大学举办了两个半天的手术技能培训讲习班，使用了8具用饱和盐溶液进行防腐的身体。共有22人参加了工作坊，其中包括口腔外科医生、住院医生和牙医。外科培训包括六个与口内和口外取骨相关的程序。在每个研讨会结束之前和之后，参与者被调查以评估每个外科手术的自信水平。采用Wilcoxon符号等级检验比较培训前后各评分中位数的差异。在颧骨(P=0.003)、上颌骨结节(P=0.002)和其他部位(P<；0.001)的自评信心评分中，有统计学意义的增加。对饱和盐液防腐身体的解剖学特征也进行了研究。口腔粘膜和皮肤的质地与活人相似。骨组织结构保存完好，硬度逼真。因此，所有的程序都是以足够的现实主义进行的。饱和盐溶法制备和储存成本相对较低，且几乎没有异味。作者认为，饱和盐液防腐身体可以为口腔外科手术技能训练提供一种新的模式。
The purpose of this study was to assess the usefulness of saturated salt solution-embalmed cadavers for oral surgical skills training related to bone graft harvesting. Two half-day surgical skills training workshops were held at the Tokyo Medical University utilizing eight cadavers embalmed with the saturated salt solution. A total of 22 participants including oral surgeons, residents, and dentists attended the workshop. Surgical training consisted of six procedures related to intraoral and extraoral bone harvesting. The participants were surveyed to assess self-confidence levels for each surgical procedure before and after completion of each workshop. The Wilcoxon signed-rank test was used to compare the differences between each median score before and after the workshop. There were statistically significant increases in the self-assessed confidence scores in bone harvesting procedures for the zygomatic bone (P = 0.003), maxillary tuberosity (P = 0.002), and other sites (P < 0.001). The anatomical features of saturated salt solution-embalmed cadavers were also examined. The textures of the oral mucosa and skin were similar to those of living individuals. The structure of bone tissues was well-preserved and the hardness was realistic. Consequently, all procedures were performed with sufficient realism. The saturated salt solution method has a relatively low cost of preparation and storage, and almost no odor. The authors suggest that saturated salt solution-embalmed cadavers could provide a new model for oral surgical skills training in bone harvesting.
