Evaluation of high placed jugular bulbus density with multislice temporal computed tomography

Abstract

Aims: In this study, it is aimed to investigate the density of high placed jugular bulbus (HPJB), which is useful to know from a clinical and surgical perspective. Methods: Between the dates of May and November 2023, temporal computed tomography (CT) scans which took place in the CT (General Electric) were evaluated retrospectively.742 cases and 1484 ears were included in the study. Jugular bulbus (JB) was evaluated based on the internal acoustic canal (IAC). Results: The age range of 742 cases was 18-72. Of the cases, 796 were women and 688 were men. HPJB was detected in 44 (3%) of 1484 ears. Of the 44 ears in which HPJB was detected, 26 (59%) were located on the right and 18 (41%) were located on the left. HPJB were monitored more frequently on the right side. Conclusion: HPJB can cause various otological symptoms, especially tinnitus. Additionally, not knowing the existence of HPJB increases morbidity rates, especially in lateral skull base surgery. In various otological findings of unknown etiology and preoperatively before lateral skull base surgery, the jugular bulb should be evaluated with temporal CT.
