OBJECTIVE: To discuss the possible pathophysiologic mechanism of pulsatile tinnitus (PT) perception due to high jugular bulb with bony dehiscence (HJBD) and its improvement after the dehiscent jugular bulb (JB) resurfacing using bone cement, and to describe the efficacy of an objective measure of PT using transcanal sound recording and spectro-temporal analysis (TSR/STA).
STUDY DESIGN: Retrospective case series study.
SETTING: A university-based, tertiary care cancer center.
PATIENTS: Three PT patients with HJBD.
MAIN OUTCOME MEASURE(S): All patients underwent transtympanic resurfacing after the source of PT was confirmed by temporal bone imaging and TSR/STA. Improvement of symptom and the changes in the TSR/STA were analyzed.
RESULTS: In the first case, a revision operation was performed due to slightly improved but persistent PT after initial resurfacing with bone pate and a piece of conchal cartilage. Revision transtympanic JB resurfacing was performed in this case using bone cement, and PT resolved immediately after the surgery. In the second and third cases, PT resolved completely, or was much abated, immediately after transtympanic resurfacing with bone cement. The TSR/STA also revealed improvement of PT. The median follow-up duration was 28 months, and all three patients remained asymptomatic or much improved compared with their preoperative status.
CONCLUSIONS: Transtympanic resurfacing with bone cement, reinforcing the dehiscent JB to reduce focal turbulent flow, is a simple and effective surgical treatment option in patients with PT due to HJBD. In patients with HJBD, the objective measurement of PT by TSR/STA may be of help in selecting appropriate surgical candidates and objective evaluation of the treatment outcome.
