摘要
研究了11只实验性头外伤的豚鼠。分为第一组(即死组)和第二组(15日组)。颞骨连续切片,HE染色。光镜观察。实验结果证明迷路窗破裂率高达59.1%。两组窗膜破裂率及左右耳窗膜破裂率没有显著差异。窗破裂耳与头受击部位无关。结论认为头外伤后迷路窗破裂率高,与临床观察一致。动物头外伤后不能制动,可能影响15日组动物破裂迷路窗的愈合。
Eleven guinea pigs following experimental head injury have been studied. The animals were divided into two groups. The first group was killed immediately after injury, The second was kept alive for 15 days. The temporal bones were sectioned serially, stained with HE and observed under light microscope, The results showed that the incidence of rupture of the labrynthine window was up to 59.1%. The incidence of rupture between the right and left ears, and between the two groups had no significant difference. The rupture was not related to the area of blow. Thus, we consider that there are high incidence of PLF after head injury and the experimental results correspond to clinical findings. Because the experimental animals were hardly immobilized, it is possible to affect healing of PLF in the animals of the second group.
