High jugular bulb is a vascular anomaly seen in the middle ear. In typical cases, the jugular bulb is easily observed through the tympanic membrane. We report here 3 patients with nontypical high jugular bulb. Their tympanic membranes were almost normal but protruded externally with pulsation when their necks were compressed. Computed tomography (CT) revealed jugular bulb protrusion into the tympanic cavities. We propose that this condition be named 'latent high jugular bulb'. Neck compression easily detects this condition and may also be useful in the detection of other disorders of the middle ear that are related to the venous system.
高位颈静脉球是一种见于中耳的血管异常。在典型病例中，通过鼓膜可轻易观察到颈静脉球。我们在此报告3例非典型高位颈静脉球患者。他们的鼓膜几乎正常，但在颈部受压时向外突出并有搏动。计算机断层扫描（CT）显示颈静脉球突入鼓腔。我们建议将这种情况命名为“隐匿性高位颈静脉球”。颈部压迫易于检测出这种情况，并且可能对检测中耳其他与静脉系统相关的疾病也有用。
