Labyrinthitis is an inflammation of the part of the inner ear called the labyrinth and is usually caused by viral or bacterial infections. This condition affects balance and hearing functions, causing symptoms such as dizziness, imbalance, hearing loss and tinnitus. The infection can develop following upper respiratory tract infections such as colds, flu or middle ear infections. In the treatment of labyrinthitis, medications are used to relieve symptoms and antiviral or antibiotic therapy may be administered depending on the cause of the infection. Most patients recover within a few weeks with appropriate treatment, but some cases may have permanent balance problems or hearing loss.
