    Super-selective angiography identified vascular abnormalities in most patients with disabling pulse-synchronous tinnitus. Arteriovenous malformations and tumors were effectively treated with embolization, often combined with surgery.

    Area of Science:

    • Vascular Surgery
    • Neurology
    • Radiology

    Background:

    • Disabling pulse-synchronous tinnitus can significantly impact quality of life.
    • Identifying the underlying vascular cause is crucial for effective treatment.

    Purpose of the Study:

    • To investigate the diagnostic yield of super-selective angiography in patients with pulse-synchronous tinnitus.
    • To evaluate treatment outcomes for different vascular pathologies causing tinnitus.

    Main Methods:

    • Super-selective angiography was performed on 15 patients with disabling pulse-synchronous tinnitus.
    • Vascular abnormalities identified included arteriovenous malformations, jugular bulb chemodectomas, and arterial stenosis.
    • Treatment involved gelatin sponge embolization, with or without surgery.

    Main Results:

    • Angiography revealed arteriovenous malformations in 8 patients, chemodectomas in 3, and arterial stenosis in 1.
    • Objective murmur registration correlated with positive angiographic findings.
    • Embolization was the primary treatment for arteriovenous malformations and tumors.

    Conclusions:

    • Super-selective angiography is valuable for diagnosing vascular causes of pulse-synchronous tinnitus.
    • Embolization is an effective treatment for arteriovenous malformations and tumors causing tinnitus.
    • Objective murmur auscultation can aid in patient selection for angiography.
