Studies on tympanic membrane transplants. I. Tympanic homografts.

ORL; journal for oto-rhino-laryngology and its related specialties, 1975
This investigation has shown that the results of tympanic membrane grafting in rats vary and depend on the nature of the various preservatives used. Seventy-six percent alcohol gave the best results in these series.

Tympanic Membrane and Tympanic Plate

Human Tympanic Membrane

Acta Oto-Laryngologica, 1970
Submicroscopic details of the human tympanic membrane were studied utilizing a transmission electron microscope (T. E. M.) and a scanning electron microscope (S. E. M.) Three layers were distinctly recognized; outer epidermal, middle lamina propria and inner mucous layer. In pars flaccida, the middle lamina propria is formed of loose connective tissues

The Tympanic Membrane

JAMA, 1973
A cough can be caused by a hair lying against the tympanic membrane. To the best of our knowledge, this is documented for the first time by our report of three patients with chronic cough who experienced relief after a hair was removed from the ear drum.

Tympanic membrane. Retraction pocket.

Acta oto-rhino-laryngologica Belgica, 1995
The author attempts to analyse the pathogenesis of the retraction pocket. Middle ear pressure, behaviour of both the tympanic membrane lamina propria and the stratified squamous epithelium are considered. Predisposing factors are presented. A conservative surgical treatment is suggested in cases of non-fixed retraction pockets; a radical surgical ...

[Tympanic membrane perforation ].

Duodecim; laaketieteellinen aikakauskirja, 2014
Tympanic membrane perforation may be caused by, e.g., trauma or acute or chronic middle ear infection. Perforation causes conductive hearing loss. Since it predisposes to infections, it is important to keep the ear dry. In most cases traumatic perforations heal spontaneously.
