We report two rare cases of high and dehiscent jugular bulbs protruding into the external ear canal; one case was silent, the other symptomatic.
The cases are presented and the relevant literature reviewed and discussed.
A 52-year-old woman underwent mastoid exploration for suspected cholesteatoma. On raising the tympanomeatal flap, while still lateral to the annulus, brisk venous bleeding occurred from a high, dehiscent jugular bulb in the external ear canal. The second patient, a 42-year-old man, underwent imaging for suspected glomus tumour. A high, dehiscent jugular bulb was found protruding into the external ear canal and hypotympanum.
High jugular bulbs in the middle ear have been reported many times. To our knowledge, there has only been one previous report of a high jugular bulb in the external ear. These cases illustrate the importance of full, accurate assessment of high resolution computed tomography images, and of appropriate, immediate management of bleeding.
我们报告两例罕见的高位且裂开的颈静脉球突入外耳道的病例；一例无症状，另一例有症状。
介绍病例并回顾和讨论相关文献。
一名52岁女性因疑似胆脂瘤接受乳突探查。在掀起鼓室鼓膜瓣时，在仍位于鼓环外侧时，外耳道内一个高位且裂开的颈静脉球出现活跃的静脉出血。第二例患者是一名42岁男性，因疑似颈静脉球体瘤接受影像学检查。发现一个高位且裂开的颈静脉球突入外耳道和下鼓室。
中耳高位颈静脉球已有多次报道。据我们所知，此前仅有一篇关于外耳道高位颈静脉球的报道。这些病例说明了全面、准确评估高分辨率计算机断层扫描图像以及对出血进行适当、及时处理的重要性。
