A recent review concludes it’s the result of an infectious or inflammatory condition. It also refers to fact steroids are the mainstay of treatment
Medical Hypothesis 122 (2019) 184-187.
Time and geographic clustering of adult patients with unilateral idiopathic sudden sensorineural hearing loss
Sapideh Gilani et al
- Sudden sensorineural hearing loss (SSNHL)- unilateral hearing loss which evolves in less than 72 h with a minimum 30 dB (dB) loss in 3 frequencies
- Analysis showed a seasonal variation like some viral infections
Mainstay of treatment are steroids – either through eardrum or oral – each as effective and the latter easier to obtain though more prone to side effects
Dose was determined from this study:
Rauch SD, Halpin CF, Antonelli PJ, et al.
Oral vs Intratympanic Corticosteroid Therapy for Idiopathic Sudden Sensorineural Hearing Loss: A Randomized Trial.
- oral was 60 mg/d of oral prednisone for 14 days with a 5-day taper (have to warn re risk of osteonecrosis hip and need to up diabetic meds)
- full recovery with oral was 20.7% (25 of 121)
- recovery to hearing aid range with oral was 66.9%
- oral “side effects” seen included myocardial infarction, cerebral hemorrhage, hyponatremia (low blood salt), hospitalization for possible transient ischemic attack, and syncope – though think some of it speak for fact these are older folk…
Comment – there is an ergency to get these people of steroids ASAP
