Jugular bulb diverticula may extend either laterally in the tympanic cavity or medially towards the petrous pyramid close to the inner ear. In the first case, this leads to subjective symptoms related to the presence of a mass at the level of the tympanic cavity and the external auditory canal and thus to conductive hearing loss and pulsatile tinnitus. In the second case, vertigo, pulsatile tinnitus and sensorineural hearing loss occur. 4 cases of jugular bulb diverticula are described (1 medial type, 3 lateral type).
颈静脉球憩室可向鼓室内侧延伸，也可向靠近内耳的岩锥内侧延伸。在前一种情况下，会导致与鼓室和外耳道水平出现肿物相关的主观症状，进而导致传导性听力损失和搏动性耳鸣。在后一种情况下，则会出现眩晕、搏动性耳鸣和感音神经性听力损失。本文描述了4例颈静脉球憩室（1例内侧型，3例外侧型）。
