Pulsatile tinnitus after head trauma may stem from vascular anomalies. A dominant jugular bulb was identified as the cause in this objective tinnitus case.

Area of Science:

  • Neurology
  • Otolaryngology
  • Vascular Surgery

Background:

  • Pulsatile tinnitus can arise from vascular abnormalities in the head and neck.
  • Objective tinnitus is audible to both the patient and examiner.
  • Vascular anomalies are a known, though less common, cause of pulsatile tinnitus.

Observation:

  • A patient presented with one year of right-sided pulsatile tinnitus following cranial trauma.
  • Magnetic resonance angiography revealed a dominant jugular bulb on the same side as the tinnitus.
  • High-sensitivity microphone recordings and distortion product otoacoustic emissions were utilized for assessment.

Findings:

  • The dominant jugular bulb was identified as the likely source of the pulsatile tinnitus.
  • The vascular anomaly correlated with the patient's subjective and objective tinnitus symptoms.

  • Objective tinnitus was confirmed, indicating the sound was perceptible to others.

    • Implications:

    • This case highlights the importance of considering vascular anomalies, specifically jugular bulb dominance, in post-traumatic pulsatile tinnitus.
    • Accurate diagnosis through advanced imaging like MRA is crucial for identifying the underlying cause.
    • Understanding these vascular origins can guide targeted treatment strategies for objective tinnitus.
