Tinnitus: causes, diagnosis & what really helps with ringing in the ears
At a glance
FrequencyIn Germany, estimates suggest millions of people develop tinnitus each year; in a relevant share it becomes chronic
DefinitionChronic tinnitus = ear noises that have lasted at least three months and are distressing to the affected person
Not dangerousTinnitus is usually not a sign of a dangerous condition — but it can considerably impair quality of life
TreatmentCounselling, CBT, hearing aids, self-help — no medication with proven efficacy against chronic tinnitus
GuidelineS3 guideline Chronic Tinnitus (DGHNO-KHC, AWMF 017-064, updated 2021)
ICD-10H93.1 (tinnitus)
1. What is tinnitus?
Tinnitus is the perception of sounds in the ear or head without any external sound source — beeping, whistling, rushing, humming or ringing. Almost everyone occasionally experiences brief tinnitus — that is normal and usually harmless.¹
It becomes a problem when the tinnitus no longer fades. It is considered chronic when it has lasted at least three months and is distressing to the affected person. The distress is highly individual — some people can ignore their tinnitus well, others suffer considerably from sleep disorders, concentration problems, anxiety or depression.¹,²
Tinnitus is usually not a dangerous sign
The vast majority of cases are benign. Even so, an evaluation should be done to rule out treatable causes.
2. Causes
Tinnitus is a symptom, not a disease in its own right. The causes are diverse.¹
Hearing loss
The most common cause. Tinnitus almost always occurs together with a reduction in hearing — even if this has not yet been noticed. The tinnitus frequency usually lies in the range of the greatest hearing loss.
Noise damage
Noise exposure (e.g. concerts, occupational noise, headphones at high volume) can trigger both acute and chronic tinnitus.
Sudden hearing loss
Sudden one-sided hearing loss (sudden sensorineural hearing loss), often associated with tinnitus.
Ear conditions
Middle ear infection, earwax plug, otosclerosis.
Stress and psychological strain
Stress does
not directly cause tinnitus, but it can considerably amplify the perception and distress.
Depression and anxiety disorders frequently occur together with distressing tinnitus.
Jaw joint and cervical spine
Dysfunction of the jaw joint (temporomandibular disorder, TMD/CMD) or tension in the area of the cervical spine can trigger or amplify tinnitus.
Medications (ototoxic)
Certain medications can trigger tinnitus as a side effect — including certain antibiotics, NSAIDs in high doses, loop diuretics, chemotherapeutic agents.
Rare, but important: pulsatile tinnitus
Acoustic neuroma (a benign tumour of the auditory nerve, also called vestibular schwannoma) and vascular anomalies (pulsatile tinnitus) are rare but important differential diagnoses. Pulsatile tinnitus (in sync with the heartbeat) should always be evaluated.
3. Symptoms and distress
Forms of tinnitus
- One-sided or both-sided
- Various sound characters: beeping, whistling, rushing, humming, ringing, chirping
- Tonal tinnitus (a single tone) or rushing tinnitus
- Pulsatile tinnitus (in sync with the heartbeat) — should always be evaluated
Accompanying complaints
Distress > loudness
The guideline emphasizes: the distress caused by tinnitus depends less on the loudness of the noise than on the psychological processing and the accompanying comorbidities.¹
4. Diagnosis
- ENT examination: otoscopy (looking into the ear), hearing test (audiogram). A hearing loss is usually found in chronic tinnitus.
- Tinnitus questionnaire: standardized questionnaires (e.g. the Tinnitus Questionnaire by Göbel and Hiller, and the THI) capture the severity of the distress and help with treatment planning.
- Tinnitus matching: determining the tinnitus frequency and loudness — can be helpful for treatment.
- Evaluation of comorbidities: depression, anxiety disorders, sleep disorders, jaw joint problems, cervical spine problems.
- Imaging: usually only for one-sided tinnitus (to rule out acoustic neuroma) or for pulsatile tinnitus (vascular evaluation). Not routinely necessary.
