There are few papers on experimental burns of the external ear. An experimental model was made and a study was conducted on 18 white rabbits to evaluate the response of the rabbit ear in relation to temperature, surface and histologic appearances and healing response with depth of injury. The rabbit model showed that: a) the rabbit ear resembled that of the human ear in histological structure. b) there was a definite correlation of the temperature of the scalding agent with the depth of the injury. c) it was possible to classify morphologically the depth of injury based on surface appearance. d) there was an accurate morphologic correlation with that of histopathologic assessment of burns depth. e) the sequential biopsy at different times (immediate, third, fifth day) showed that the depth of the burns was already apparent soon after the injury. f) there was also a correlation of burns depth with the rate of ear healing.
关于外耳实验性烧伤的论文较少。制作了一个实验模型，并对18只白兔进行了研究，以评估兔耳在温度、表面和组织学外观以及愈合反应与损伤深度方面的情况。兔模型显示：a）兔耳在组织结构上与人类耳朵相似。b）烫伤剂的温度与损伤深度有明确的相关性。c）根据表面外观对损伤深度进行形态学分类是可能的。d）与烧伤深度的组织病理学评估存在准确的形态学相关性。e）在不同时间（即刻、第三天、第五天）进行的连续活检表明，烧伤深度在受伤后不久就已显现。f）烧伤深度与耳部愈合速度也存在相关性。
