Spontaneous Healing of Traumatic Eardrum Perforation

Abstract

Although the outward epithelial migration did not affect the overall perforation spontaneous healing rate, it alone could not close the perforation. The prerequisite for eardrum healing is that the outward epithelium migration pattern evolves into a centripetal migration pattern. Consequently, outward epithelial migration prolonged substantially the time to traumatic eardrum perforation closure.
