The human temporal bones of five drowning victims, the largest such series, to our knowledge, were evaluated to determine what histopathologic changes occurred. Thickening of the periosteal epithelium, especially on the surgical dome of the otic capsule, was evident in all cases. There was also hemorrhage in the middle ear cavity in four of the cases. In the fifth case, a cholesteatoma and ruptured tympanic membrane were observed, but there was no evidence of hemorrhage. It is proposed that an intact tympanic membrane is needed to create sufficient negative pressure in the middle ear cavity to cause rupture of the blood vessels and hemorrhage. Such bleeding is indicative of drowning when the tympanic membrane is intact.
据我们所知,对五名溺水受害者的颞骨进行了评估,这是此类最大规模的系列研究,以确定发生了哪些组织病理学变化。所有病例中均可见骨膜上皮增厚,尤其是在听囊的手术穹窿处。其中四例中耳腔内也有出血。在第五例中,观察到胆脂瘤和鼓膜破裂,但没有出血迹象。有人提出,需要完整的鼓膜在中耳腔内产生足够的负压,以导致血管破裂和出血。当鼓膜完整时,这种出血表明是溺水所致。
