title: The fiber arrangement of the pathological human tympanic membrane.
abstract: Remarkable morphological changes of the fiber arrangement was observed in the middle lamina propria of the pathological human tympanic membranes. These changes were present mainly in the middle zone of the pars tensa. There were several fibers running in entirely different directions among the regularly arranged radial and circular fibers. These abnormal fibers had a tendency of forming fiber bundles of varying sizes and lengths. It is stressed that the normal fiber arrangement was undoubtedly disordered in the healing process of the inflamed middle lamina propria of the human tympanic membrane.
