Five temporal bones exhibiting transverse fractures were studied with a view to determining whether such fractures could lead to symptomatic endolymphatic hydrops. Four out of the five temporal bones showed the fracture line traversing the vestibular aqueduct. Two of these four showed complete obstruction of the endolymphatic duct. One of these had an intact membranous labyrinth and severe endolymphatic hydrops. The other had ruptures of the membranous labyrinth and no hydrops. Three ears exhibited partial preservation of auditory and vestibular hair cells and neurons. These findings are consistent with the concept that a transverse fracture may produce endolymphatic hydrops by obstructing the vestibular aqueduct while preserving enough audiovestibular epithelium and neurons to present as symptomatic Menière's disease.
对五块呈现横行骨折的颞骨进行了研究，目的是确定此类骨折是否会导致有症状的内淋巴积水。五块颞骨中有四块显示骨折线穿过前庭导水管。这四块中的两块显示内淋巴管完全阻塞。其中一块的膜迷路完整且有严重的内淋巴积水。另一块的膜迷路有破裂且无积水。三只耳朵的听觉和前庭毛细胞及神经元有部分保留。这些发现与以下概念一致，即横行骨折可能通过阻塞前庭导水管而产生内淋巴积水，同时保留足够的听前庭上皮和神经元，从而表现为有症状的梅尼埃病。
