Abstract:There are various types of anatomic abnormality of jugular bulb. High jugular bulb is one of the most common anatomical variations. A probability of occurrence is diversity due to different criteria of clinical classification. Anatomic abnormality of jugular bulb can always be ignored in clinic since most of patients with high jugular bulb are asymptomatic. However，it is the most common vascular anomaly of the petrous temporal bone. It is easy to cause fatal intraoperative hemorrhage in middle ear, inner ear and lateral skull base surgery due to neglect. Its symptoms were changeable and easily masked by other diseases.
