Pressure equalization within the tympanum for a sufficient length of time can be produced by making burn perforations in the tympanic membrane. Small multiple perforations placed close to each other or a large perforation of about one eighth of the quadrant of the tympanic membrane will equalize the pressure for more than three months. The procedure in described in detail.
It is a minor procedure comparable to a myringotomy or removing plugged debris from ventilation tubes.
