Epithelial migration on the tympanic membrane of children

An ink-dot staining technique was used to determine the pattern and rate of epithelial migration in children with normal tympanic membranes. Epithelial migration was observed to occur in a predominantly postero-superior direction. The mean daily rate of migration was 131 micron per day, being at its greatest in the region of the umbo. These findings are compared with those previously recorded in adults.
