Tympanic membrane retraction over the surface and move out along the ear canal. Even if migration along the ear canal is blocked, new cells continue to grow so the surface of the eardrum becomes larger. This process of proliferation and migration can result in enlargement of a retraction pocket so that the eardrum expands and grows deeper into the ear. The majority of tympanic membrane retractions remain stable for long periods of time, or may even resolve spontaneously so that eardrum becomes normal again. Not all retractions are able to resolve even if middle ear pressure normalizes, as the retracted segment may become
What Is the What "we really hadn’t decided whether I was just helping Valentino write his own book, or if I was writing a book about him." Valentino points out that, "I thought I might want to write my own book, but I learned that I was not ready to do this. I was still taking classes in basic writing at Georgia Perimeter College."
