Paraganglioma of the tympanic membrane
The Journal of Laryngology & Otology, 1985Von Haller, in 1743, first described the carotid body and was so impressed with the richness of its innervation that he called it 'ganglion minutum', thinking it to be a sympathetic ganglion. Valentine, in 1840, saw a peculiar structure in the tympanic canaliculus in which a nerve cell was present and called it 'gangliolum tympanicum'. Almost 100 years

Anesthesia of the Tympanic Membrane
Archives of Otolaryngology - Head and Neck Surgery, 1995Concerning the letter to the editor by Guldberg1that appeared in the December 1993 issue of theArchives, I want to make the following remarks. Anesthesia of the tympanic membrane is a difficult challenge if topical application is intended. Many mixtures and substances have been proposed, but none of the hitherto known anesthetics lacks drawbacks.

Nature of the tympanic membrane insertion into the tympanic bone of the rat
Hearing Research, 1999The nature of the insertion of the tympanic membrane into the tympanic bone was studied in the rat during the developmental period ranging from 18 days post conception (dpc) to 40 days after birth (dab). Techniques applied were light microscopy, electron microscopy and immunohistochemistry with antibodies to cytoskeletal proteins: vimentin, desmin and ...

Vascular anomalies of the tympanic membrane
The Journal of Laryngology & Otology, 2006Benign vascular lesions include various forms whose classification has created some controversies in the literature. The observation of a rare case of vascular bulge of the eardrum in a 57-year-old man prompted us to analyse the essential features of these lesions. This was an incidental finding and the mass was removed by a transcanal approach.

Otology & Neurotology, 2001
Several theories have been proposed with respect to the origin and pathogenesis of cholesteatoma behind an intact tympanic membrane.The authors describe a case of cholesteatoma behind an intact tympanic membrane in a 71-year-old man with a history of tympanic membrane retraction fixed to the incus without evidence of a perforation.

Function of the Tympanic Membrane
The Journal of the Acoustical Society of America, 1970Vibrational holography was performed on tympanic membranes (TM) in human temporal bones obtained immediately after death. Displacement patterns at the first mode (and also at higher modes) were essentially the same as those found in cats (Khanna et al., 1969). Findings in both species can best be reconciled with the catenary concept of Helmholtz (1868).

The tympanic membrane of a human adult is oval or elliptical in shape, with its major axis 9.0–10.2 mm in length and minor axis 8.5–9.0 mm. The tympanic membrane is divided into tense and flaccid portions and histologically consists of three layers, epidermis, lamina propria and mucosa. The flaccid portion lacks the lamina propria. The annular ligament

Tympanic Membrane Response in the Cricket
Nature, 1970THE analysis of the frequency response to sound of individual nerve fibres in the orthopteran ear indicates that the fibres are most sensitive at a particular frequency (usually between 4 and 6 kHz), but that this frequency tends to be the same for all fibres1,2.

Tympanic membrane perforations
2018This chapter discusses Macfadyen, Acuin, and Gamble’s paper on systemic antibiotics versus topical treatments for chronically discharging ears with underlying eardrum perforations including the design of the study, (including outcome measures, results, conclusions, and a critique).
