Intratympanic corticosteroid for sudden hearing loss: does it really work?

Introduction: Sudden deafness is characterized by an abrupt hearing loss of at least 30dB in three sequential frequencies in the standard pure tone audiogram over three days or less. Treatment is based on its etiology, and oral corticosteroids are widely used. Intratympanic corticosteroids are included as primary or secondary treatment when there is no improvement with the use of oral corticosteroids.
