A traumatic event may result in sudden onset of hearing loss or dizziness. When the vestibular evaluation confirms the diagnosis as Perilymph Fistula, the patient is advised to refrain from physical activities for a week or two.
Usually, sufficient resting heals the tear in the middle ear membranes and stops the perilymph from leaking. In spite of precautions, if the symptoms persist surgery may be required. The PLF patients should avoid coughing, bending over, straining, lifting things or any other such activities that aggravate the symptoms of PLF.
The surgery is done under local anaesthesia to repair the Perilymph Fistula. The operation is carried out through the ear canal. During the operation, the eardrum is raised, and tiny soft tissue grafts are placed around the oval window and the round window.
The patients are advised bed rest and restricted activities at home for the next three days post-surgery. Overnight hospitalization is often advised.
After three days of rest, for the duration of a month, the patient can resume normal, but not strenuous activities. The patient should avoid intense sports activities like weight lifting, diving, flying or roller coaster rides. It is seen that patients experience PLF symptoms again if these precautions are not taken, even after successful surgery. Patients are also given laxatives after surgery to avoid straining.
