This study aimed to measure the radiological dimensions of the cochlear aqueduct in Meniere's disease and in low-frequency hearing loss (LFHL) patients and control patients.
Groups of 26 patients (32 ears, including 6 with bilateral involvement) with Meniere's disease, 14 patients (18 ears) with LFHL, and 23 patients with unilateral chronic otitis media, as controls, were enrolled. For the measurements, high-resolution computed tomography (HRCT) of the temporal bone was performed. The cochlear aqueduct was evaluated for the following six parameters: medial opening (MO), petrous apex (PA), otic capsule (OC), lateral opening (LO), distance of the cochlear aqueduct (DC), and length of the cochlear aqueduct (LC).
The PA, OC, DC, and LC were not significantly different between the groups. LO could not be measured because the LO was not visible in all cases. The MO diameter was narrower in the Meniere's disease group than in the LFHL group (p=0.001) and in the controls (p=0.035). When the dimensions of both ears were measured in patients with unilateral Meniere's disease, no statistically significant difference was found.
Compared to LFHL and controls, the MO of the cochlear aqueduct was significantly smaller in the Meniere's disease group.
本研究旨在测量梅尼埃病患者、低频听力损失（LFHL）患者及对照患者的蜗水管的影像学尺寸。
纳入26例梅尼埃病患者（32耳，其中6例为双侧患病）、14例LFHL患者（18耳）以及23例单侧慢性中耳炎患者作为对照。测量时，对颞骨进行高分辨率计算机断层扫描（HRCT）。对蜗水管评估以下六个参数：内侧开口（MO）、岩尖（PA）、耳囊（OC）、外侧开口（LO）、蜗水管距离（DC）和蜗水管长度（LC）。
各组之间PA、OC、DC和LC无显著差异。由于并非在所有病例中都能看到LO，所以无法测量LO。梅尼埃病组的MO直径比LFHL组（p = 0.001）和对照组（p = 0.035）更窄。在单侧梅尼埃病患者中测量双耳尺寸时，未发现统计学上的显著差异。
与LFHL组和对照组相比，梅尼埃病组蜗水管的MO明显更小。
