The jugular bulb (JB) varies widely in position, size and shape. A high position of the jugular bulb may rarely lead to clinical symptoms. This position is may more often lead to dificulties not only during otosurgical operations, but also during lateral and posterolateral transtemporal approaches in skull base surgery. The authors discuss the definition of high jugular bulb and prefer from the roentgenological and clinical point of view the bulb’s position in relation to the meatus acusticus internus as the best for evaluation. The authors’ opinions are presented on the analysis of a group of 50 skull bases. There were 15% high positions of the bulb and 3% extreme by high. The right side and female gender dominate in the group of high jugular bulbs. Article also discusses the diagnostics of JB position and complications associated with its damage during surgery.
