Fluorescein angiography of the tympanic membrane.
Little is known about the dynamic vasculature of the tympanic membrane, despite the fact that it is within easy view of the otolaryngologist. An understanding of its blood supply dynamics may lead to a better understanding of the tympanic membrane's physiological properties and response to surgery. Also, certain patterns of blood flow may correlate with disease entities and be of diagnostic value. Currently, we have done 30 fluorescein angiograms of the tympanic membrane. The fluorescein angiograms from a normal ear and from ears with several types of ear pathology are described.
