摘要
目的:探究锥形束计算机断层扫描(CBCT)在颞骨细微结构测量的可行性及正常值范围。方法:15例福尔马林浸泡固定的人类尸头标本分别行CBCT、高分辨率CT、Micro CT扫描,对包括听骨链、耳蜗、半规管及面神经等在内的中内耳结构进行形态学测量,比较三种扫描方法所测结果间差异。结果:三种不同CT扫描所测参数组间对比除镫骨底板厚度(P<0.01)及耳蜗底周管径(P<0.01)外,余差异均无统计学意义。CBCT对面神经骨管缺损具有较好的诊断价值。结论:CBCT扫描时间短,辐射剂量小,成像质量高,能较准确地显示颞骨内各精细结构的形态特点,是耳科影像学的可靠评估方法。
Objective: To identified the feasibility and normal range of cone beam computer tomography(CBCT) in the measurement of temporal bone. Methods: 15 formalin fixed human cadaver head specimens were scanned by CBCT, high resolution CT, and Micro CT, respectively. Morphological parameter measurements of the middle and inner ear structures including ossicular chain, cochlea, semicircular canal and facial nerve were performed, and the results measured by the three scanning methods were compared. Results: None of the parameters measured by the three scanning methods were statistically significant except the thickness of stapes footplate(P<0.01) and the diameter of cochlear basal turn(P<0.01). CBCT was superior in detecting facial nerve bony canal dehiscence. Conclusion: CBCT has the advantages of short scanning time, low radiation dose and high resolution. It can accurately display the morphological characteristics of the temporal bone structures, and is a reliable evaluation method for otological surgery.
