Sudden Ear Pain with Hearing Decrease
Treat this as sudden sensorineural hearing loss (SSNHL) until proven otherwise—this is an otologic emergency requiring urgent audiometry and corticosteroid therapy within 2 weeks of symptom onset for optimal outcomes. 1
Immediate Evaluation
Obtain an audiogram immediately to confirm SSNHL, defined as ≥30 dB hearing loss across three consecutive frequencies occurring within 72 hours. 2 Do not delay treatment waiting for imaging or laboratory tests, as these are not routinely indicated for diagnosis. 1
Key History and Physical Elements
- Timing: Document exact onset of symptoms (critical for treatment window) 1
- Associated symptoms: Ask specifically about tinnitus, vertigo, and ear fullness—vertigo at onset indicates poorer prognosis 1
- Laterality: Bilateral sudden hearing loss suggests systemic disease and requires different workup 3
- Otoscopic exam: Rule out cerumen impaction, tympanic membrane perforation, or middle ear effusion (conductive causes) 2
Initial Treatment
Offer systemic corticosteroids as initial therapy within 2 weeks of symptom onset (ideally within 14 days, though benefit reported up to 6 weeks). 1 This recommendation is based on systematic reviews showing potential hearing improvement that profoundly impacts quality of life, despite some contradictory evidence on efficacy. 1
Corticosteroid Dosing Options
- Prednisone: 1 mg/kg/day (maximum 60 mg/day) for 7-14 days, then taper over similar period 1
- Methylprednisolone: 48 mg/day 1
- Dexamethasone: 10 mg/day 1
Alternative: Intratympanic (IT) Corticosteroids
For patients with contraindications to systemic steroids (insulin-dependent diabetes, labile hypertension, glaucoma, peptic ulcer disease, psychiatric reactions to steroids), IT steroid injections are non-inferior in efficacy. 1
- Dexamethasone: 24 mg/mL (compounded) or 10 mg/mL, inject 0.4-0.8 mL into middle ear 1
- Frequency: Up to 4 injections over 2 weeks 1
- Technique: Patient maintains affected ear up for 15-30 minutes post-injection 1
Important Caveats
- Spontaneous recovery occurs in one-third to two-thirds of patients, making treatment benefit assessment challenging 1
- Antivirals are NOT recommended despite common prescription—insufficient evidence supports effectiveness 1
- Hyperbaric oxygen may be offered within 2 weeks of diagnosis or up to 1 month in conjunction with steroids, though evidence is limited 1
Salvage Therapy
Offer intratympanic steroids for incomplete recovery after initial therapy (typically after 2 weeks of symptom onset). 1 This represents standard salvage treatment when initial systemic steroids fail to restore hearing.
Imaging for Retrocochlear Pathology
Order MRI with gadolinium of the internal auditory canals and brain to screen for vestibular schwannoma, which occurs rarely but requires detection. 1 While MRI is most sensitive, auditory brainstem response (ABR) is an acceptable less expensive screening alternative, though abnormal ABR requires subsequent MRI. 1
Imaging Indications
- All patients with confirmed SSNHL should undergo imaging 3
- Asymmetrical hearing loss mandates imaging 2
- Bilateral sudden hearing loss requires urgent systemic disease workup 3
Prognosis and Follow-up
- Patients recovering 50% of hearing within first 2 weeks have better prognosis 1
- Minimal change within first 2 weeks predicts poor recovery 1
- Obtain follow-up audiometry within 6 months of initial diagnosis 1
- Address audiologic rehabilitation early, including counseling on amplification options 1
Common Pitfalls
- Delaying audiometry: Hearing test must be done immediately, not after "watchful waiting" 1
- Missing the treatment window: Corticosteroids are most effective within 14 days; don't delay for imaging results 1
- Assuming viral etiology: No evidence supports antiviral therapy despite historical use 1
- Ignoring contraindications to systemic steroids: IT steroids provide equivalent efficacy without systemic side effects 1
- Failing to image: All SSNHL patients need retrocochlear pathology screening 3
