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