Abstract

The aim of this study was to determine and compare the capability of the High-Resolution Computed Tomography (HRCT) and endoscope in detecting hidden areas of medial retrotympanum in cases with chronic otitis media (COM). Per-operative endoscopic evaluation of structures in medial retrotympanum was done in 74 patients suffering from COM and was compared with pre-operative HRCT of the temporal bone in 50 patients. HRCT revealed type-A Sinus Tympani (ST) in 61.2%, type-B in 34.7%, and type-C in 4.1% of the patients; endoscope could reveal type-A in 71.6%, type-B in 25.7% and type-C in 1.4% of the patients. Ponticulus was discovered in 84.1%, subiculum in 100%, finiculus in 97.3% and sinus subtympanicus (SST) in 100% of the cases using endoscope. HRCT could detect ponticulus in 38.6% and subiculum in 4.0% of the cases. HRCT could not very clearly detect finiculus and SST. HRCT could not differentiate the content of the ST as compared with endoscopy. HRCT is a useful diagnostic tool in predicting the presence and type of ST, but its accuracy in detecting SST, finer bony ridges of ponticulus, subiculum, and finiculus and the contents is poorer than endoscope.

通过高分辨率计算机断层扫描和内窥镜对内侧鼓膜进行评估--一项描述性研究。
本研究旨在确定并比较高分辨率计算机断层扫描(HRCT)和内窥镜在检测慢性中耳炎(COM)患者鼓室内侧后部隐蔽区域方面的能力。对 74 名慢性中耳炎患者进行了鼓室内侧后部结构的围手术期内窥镜评估,并与 50 名患者术前的颞骨高分辨计算机断层扫描进行了比较。HRCT 显示 61.2% 的患者为 A 型鼓室窦(ST),34.7% 为 B 型,4.1% 为 C 型;内窥镜显示 71.6% 的患者为 A 型,25.7% 为 B 型,1.4% 为 C 型。使用内窥镜可发现 84.1%的患者有骨膜,100%的患者有骨膜下腔,97.3%的患者有骨膜下腔,100%的患者有鼓室下窦(SST)。在 38.6% 的病例中,HRCT 可以检测到蝶窦,在 4.0% 的病例中,HRCT 可以检测到蝶窦下。HRCT 不能非常清晰地检测到蝶窦和蝶窦下。与内窥镜检查相比,HRCT 无法区分 ST 的内容。HRCT 在预测 ST 的存在和类型方面是一种有用的诊断工具,但它在检测 SST、盂、盂下和蝶窦的较细骨脊以及内容物方面的准确性比内窥镜差。
