Sudden sensorineural hearing loss (SSNHL) is defined as ≥30 dB SNHL over at least 3 consecutive frequencies occurring within 72 hours. The first-line treatment according to current guidelines is:
- A Systemic (oral) corticosteroids ✓
- B Intratympanic gentamicin
- C Hyperbaric oxygen therapy
- D IV carbogen inhalation
Correct answer: A. Systemic (oral) corticosteroids
Explanation
According to the AAO-HNS 2019 guidelines (and Dhingra), high-dose systemic corticosteroids (oral prednisone 1 mg/kg/day up to 60 mg for 7–14 days) remain the first-line treatment for idiopathic SSNHL. The presumed mechanism is reduction of endocochlear inflammatory oedema and immune-mediated inner ear injury. Intratympanic steroid injection is an evidence-based alternative or salvage option for patients unable to tolerate systemic steroids. Hyperbaric oxygen is adjunctive, and carbogen is no longer standard of care.
