Initial Workup for Tinnitus
The initial workup for a patient presenting with tinnitus should include a targeted history and physical examination, followed by a comprehensive audiologic examination within 4 weeks, regardless of laterality, duration, or perceived hearing status. 1
History and Physical Examination
The targeted history should assess:
Tinnitus characteristics:
- Laterality (unilateral vs. bilateral)
- Duration (recent vs. persistent ≥6 months)
- Quality (ringing, buzzing, pulsatile, etc.)
- Timing (constant vs. intermittent)
- Severity and impact on quality of life
Associated symptoms:
- Hearing loss
- Vertigo or dizziness
- Aural fullness
- Otorrhea
- Otalgia
- Neurological symptoms
Physical examination:
- Otoscopic examination
- Cranial nerve assessment
- Auscultation for bruits (if pulsatile tinnitus)
- Temporomandibular joint examination
Audiologic Testing
All patients with tinnitus should undergo comprehensive audiologic testing 1, which includes:
- Pure tone audiometry
- Speech audiometry
- Tympanometry
- Acoustic reflexes
- Otoacoustic emissions (when indicated)
This testing is particularly crucial for patients with:
- Unilateral tinnitus
- Tinnitus persisting ≥6 months
- Tinnitus accompanied by hearing difficulties 2
If dizziness is present, video- or electronystagmography (VNG/ENG) should be added 1
Electrocochleography is indicated if fluctuating hearing loss is identified during audiometry 1
Imaging Studies
Imaging studies should NOT be routinely obtained unless one or more of the following are present:
- Unilateral tinnitus
- Pulsatile tinnitus
- Focal neurological abnormalities
- Asymmetric hearing loss 1
When imaging is indicated, the appropriate studies include:
- Pulsatile tinnitus: CT angiography or MR angiography
- Unilateral tinnitus with asymmetric hearing loss: MRI with contrast of internal auditory canals
- Focal neurological findings: MRI brain with contrast 1
Psychological Assessment
- Screen for depression and anxiety, particularly in patients with severe psychological distress 1
- Assess suicide risk in patients with severe tinnitus-related distress 1
Common Pitfalls to Avoid
Ordering unnecessary imaging for bilateral, non-pulsatile tinnitus without asymmetric hearing loss or focal neurological findings 1
Delaying audiologic evaluation in patients with unilateral tinnitus 1
Ordering imaging before completing audiometric testing 1
Failing to distinguish between different types of dizziness (vertigo, lightheadedness, imbalance) 1
Telling patients "nothing can be done" when multiple management strategies exist 1
Follow-up and Referral
- Schedule follow-up within 4-6 weeks to assess response to initial management
- If symptoms persist or worsen, consider referral to a specialized tinnitus/hyperacusis clinic 1
Treatment Considerations
- Cognitive behavioral therapy is strongly recommended as first-line treatment for persistent, bothersome tinnitus 1, 3
- Sound therapy options (white noise machines, environmental sound generators, smartphone apps) can be beneficial 1
- Hearing aids are recommended for patients with hearing loss-associated tinnitus 1
- Avoid routine use of antidepressants, anticonvulsants, anxiolytics, intratympanic medications, or dietary supplements for treating persistent tinnitus due to lack of evidence 1, 3
