Repair of experimental Perforation of the tympanic membrane in the guinea pig was observed by light and polarized microscopy (surface preparation). The linear incision was done at right angles to the radial fiber bundles in the tympanic membrane of 34 guinea pigs. The perforation of the tympanic membrane closed one week after the incision. The capillary appeared after two weeks and the fibrils could be found after four weeks. The mechanical strength of the tympanic membrane recovered up to 70% of the strength of the normal tympanic membrane after seven weeks. The radial fiber bundles were not yet repaired after ten weeks.
