| 摘 要： | 目的探讨头部受力后导致脑肿胀并发TNH的相互关系。方法采用福尔马林固定的91例大脑标本,根据脑的损伤特点分三组分别作冠、矢及水平状切面,肉眼观察。结果发现脑损伤致脑肿胀后产生的TNH有三种类型,即前位疝65例(71.4％),后位疝5例(5.5％),及单、双侧全疝21例(23.1％)。其中16例全疝仍见以前位疝最显著。结论头部受力后易在额颞部发生前位疝。TNH虽与受力部位、受力机制有一定关系,但仍与受力强度、伤后存活时间关系密切。

| Abstract: | Objective To study the relations between the site of head injury and the position of brain edema induced tentorial notch herniation (TNH). Method The formalin fixed brain specimens of 91 cases were cut either coronally, or sagittally or horizontally, according to different requirement. Then, the characteristics of injury were observed. Results There were three types of brain edema induced TNH after cerebral injury: 65 cases with anterior herniation (71.4%), 5 cases with posterior herniation (5.5%), and 21 cases with unilateral or bilateral total herniation (23.1%). Anterior herniation was notable among 16 cases with total herniation. Conclusion Frontotemporal anterior herniation was the most common type of TNH after cerebral injury. The occurrence of TNH was related to the site and manner of injury, as well as the strength of force and survival interval after injury. |
