本文作者研究了7例病人14侧耳(每例至少有一侧颞骨骨折)的颞骨组织病理学。目的是观察颅底不同骨折线的颞骨组织病理学的表现。颞骨骨折可分为三型(Mc Hugh,1959):(1)纵形骨折,约占70%,主要由于颞部受伤。骨折线常起自颞骨鳞部的后面,沿岩锥的长轴,向前内延伸,经外耳道壁,中耳顶部进入颈内动脉管,止于颅中凹破裂孔附近的半月神经节。内耳不易直接受损,外耳道皮肤及鼓膜常有撕裂,致外耳道出血并伴传导性聋,面神经损伤约占20%。本文2例属此型,组织学上见耳蜗、前庭、半规管、
The authors studied the temporal bone histopathology of 14 patients with 14 lateral ears (with at least one temporal bone fracture in each case). The purpose is to observe the temporal bone histopathological manifestations of different fracture lines at the skull base. Temporal bone fractures can be divided into three types (Mc Hugh, 1959): (1) longitudinal fractures, accounting for about 70%, mainly due to temporal injuries. Fracture line often from the back of the temporal bone squamous along the long axis of the rock cone, extending forward through the external auditory meatus wall, the middle ear into the internal carotid artery, stopped in the cranial cavity near the concave half-moon ganglion. Inner ear is not easily damaged, the outer ear canal skin and tympanic membrane often tear, causing external auditory canal hemorrhage and hearing loss, facial nerve injury accounts for about 20%. This article 2 cases belong to this type, histologically see the cochlear, vestibular, semicircular canal,
