The syndrome of stenosis of the internal auditory canal is radiographically suggested by narrowing of the canal on temporal bone tomography or nonfilling on Pantopaque cysternography. The internal auditory canal ends medially at the porous acousticus. In the literature, the radiographs employed to demonstrate this stenosis show the narrowing to be medial to the porous acousticus and therefore extracanalicular. The presumed narrowing is actually in a neurovascular groove on the posterior aspect of the temporal bone. Temporal bone specimens were photographed and tomographed to demonstrate this point. These data suggest that present radiographic criteria for diagnosis of this syndrome are invalid.
内耳道狭窄综合征在颞骨断层摄影中表现为内耳道变窄，或在碘苯酯脑池造影中表现为充盈缺损，从而在影像学上提示该综合征。内耳道在内侧止于蜗孔。在文献中，用于显示这种狭窄的X线片显示狭窄位于蜗孔内侧，因此位于管外。推测的狭窄实际上位于颞骨后侧的神经血管沟内。拍摄了颞骨标本并进行断层摄影以证明这一点。这些数据表明，目前用于诊断该综合征的影像学标准是无效的。
