A study of the surgical anatomy and pathology of the round window was performed on a total of 292 serially sectioned temporal bones. The surgical approach to the round window is discussed with consideration of the anatomical findings. In the pathological study obliteration of the round window niche occurred as a congenital anomaly, in otosclerosis, chronic otitis media and as an end result in suppurative labyrinthitis. Clinical reports seem to indicate that obliteration of the window is associated with significant hearing loss, contrary to the findings in experimental animals. In chronic otitis media the round window is a pathway for spread of infection to the labyrinth, but also the finding of perilymphatic precipitates to the window in some ears suggests that certain inflammatory products may enter the scala tympani through the round window and so lead to high tone sensorineural hearing loss.
对总共292块连续切片的颞骨进行了圆窗的手术解剖学和病理学研究。结合解剖学发现讨论了圆窗的手术入路。在病理学研究中,圆窗龛闭塞作为一种先天性异常出现在耳硬化症、慢性中耳炎中,并作为化脓性迷路炎的最终结果出现。临床报告似乎表明,与实验动物的结果相反,圆窗闭塞与严重听力损失有关。在慢性中耳炎中,圆窗是感染扩散至迷路的途径,但在一些耳朵中发现圆窗有外淋巴沉淀物,这表明某些炎性产物可能通过圆窗进入鼓阶,从而导致高频感音神经性听力损失。
