Burn perforation as a method of middle ear ventilation.
Eardrum perforation caused by burn is well known to have a tendency to resist closure. This unfavorable tendency to resist closure. This unfavorable tendency can be turned to the benefit of patients with severe, Eustachian tube dysfunction. Pressure equalization of sufficient duration can be produced by making a burn perforation of the tympanic membrane. Multiple, small perforations placed closely or a large perforation of about one eighth of the tympanic membrane will remain patent and equalize pressure across the tympanic membrane for a period greater than three months. The procedure is of a minor nature comparable with myringotomy or with the removal of a plugged clot from a tube.
