Which of the following treatments is recommended to shorten the duration of labyrinthitis symptoms?

Corticosteroids are recommended for shortening the duration of labyrinthitis symptoms due to their anti-inflammatory properties. Labyrinthitis often results from an inflammatory response to infections, and corticosteroids can help reduce this inflammation in the inner ear, thereby alleviating symptoms such as vertigo, dizziness, and hearing loss more rapidly. This approach focuses on addressing the underlying inflammatory process, making it effective in managing the condition.

Other treatments like antidepressants, while possibly helpful for managing associated anxiety or depression, do not directly influence the inflammation or the duration of labyrinthitis symptoms. Antibiotics would only be effective if there is a bacterial infection present, but they do not directly target labyrinthitis itself when it is caused by viral infections. Exercise therapy, although beneficial in various rehabilitation contexts, does not address the acute inflammatory symptoms of labyrinthitis. Overall, corticosteroids provide targeted relief that is beneficial in shortening the symptomatic duration related to labyrinthitis.
