创伤性颊脂体疝的临床及机理

Clinical study and denominate of traumatic herniation of corpus adiposum buccae

目的加深对创伤性颊脂体疝的认识并揭示产生机理，为合理命名提供佐证。方法对１０例创伤性颊脂体疝临床病例观察，并采用６具（１２侧）未经处理的新鲜尸体标本实验观察。结果１侧撞击型与５侧刺戳型模拟实验成功标本的疝出物是咀嚼脂肪垫的颊突（即颊脂体），其形态大小部位与临床病例的疝出物相符。结论实验证实了临床疝出物是颊脂体而不是颊脂垫，合理的命名应是创伤性颊脂体疝。

Objective To deepen the recognition, and provide the evidence for rational name of traumatic herniation of corpus adiposum buccae.Methods 10 clinical cases of traumatie herniation of corpus adiposum buccae were studied. Simulat experiment on 6 fresh corpses (12 sides) were performed dissected immediately after bump (hitting) type and stab (thrusting) type of herniation of corpus adiposum buccae.Results In one side bump type and 5 sides stab type successful experiments, the buccal protuberance of masticatory fat pads (namely corpus adiposum beccae) were herniated into the mouth, with the shape, size, and position simulated with the herniated tissue of the clinical case.Conclusion The herniated tissue of clinical case is the corpus adiposum buccae but not the buccal fat pad, and the rational name should be traumatic herniation of corpus adiposum buccae.
