BACKGROUND AND PURPOSE
Recent advances in the display of medical images permit the routine study of temporal bone CT images at high magnification. We noted an unfamiliar structure, which we now call the "cochlear cleft," in the otic capsule. To our knowledge, this report represents the first description of this structure in the medical imaging literature.
METHODS
Temporal bone CT performed in 100 pediatric patients without sensorineural hearing loss were examined for the presence of cochlear clefts. Incidence of cochlear clefts as well as the relationship between age and incidence was examined.
RESULTS
Cochlear clefts were present in 41% of the subjects. Incidence decreased with age.
CONCLUSION
We describe a cleft in the otic capsule that is frequently seen on magnified images of temporal bone CT studies in children. The cleft may be the fissula ante fenestram.
背景与目的
医学影像显示技术的最新进展使得颞骨CT图像的高倍常规研究成为可能。我们在听骨囊中发现了一种不常见的结构，我们现在将其称为“耳蜗裂”。据我们所知，本报告是医学影像文献中对该结构的首次描述。
方法
对100例无感音神经性听力损失的儿科患者进行颞骨CT检查，以确定是否存在耳蜗裂。研究了耳蜗裂的发生率以及年龄与发生率之间的关系。
结果
41%的受试者存在耳蜗裂。发生率随年龄增长而降低。
结论
我们描述了一种在儿童颞骨CT研究的放大图像上经常出现的听骨囊裂。该裂可能是窗前裂。
