Further Inpatient Care

See the list below:

  • Bedrest with the head of the bed elevated to 30°

Complications

See the list below:

  • Both the patient and the physician should be prepared for no response to treatment, especially with regard to hearing improvement. Recurrence of postoperative signs and symptoms may occur in 21-47% of patients.
  • Perilymph fistula may be associated with recurrent meningitis in children.

Prognosis

See the list below:

  • Because of the difficulty in making the diagnosis of perilymph fistula, the natural history of this disorder is unknown.
  • Significant improvement in symptoms that are presumed to be from perilymph fistula may occur with conservative treatment.
  • Surgery is more successful in relieving vertiginous symptoms than in improving hearing.
