Hernia of the tympanic membrane
Auris Nasus Larynx, 2017Although tympanic bulging is commonly encountered, tympanic herniation occupying the external auditory canal is extremely rare. A 66-year-old man was presented to our hospital with left aural fullness, bilateral hearing loss and otorrhea. Preoperative findings suggested tympanic membrane (TM) hernia located in the left external auditory canal.

Fibroma of the tympanic membrane
American Journal of Otolaryngology, 2009A primary tumor of the tympanic membrane is very rare. Herein, we describe a patient with a thick tympanic membrane that caused progressive hearing loss. The patient was treated with total resection of the tympanic membrane and was diagnosed with fibroma after histopathologic examination. There was no evidence of recurrence 2 years after the operation,

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

The Attack on the Tympanic Membrane
Pediatrics, 1984Fluid in the ear, glue ear, and conductive hearing loss have replaced the "infected, large, or hypertrophied tonsils" and "enlarged adenoids" as a major concern of primary physicians caring for children and the special domain of ear, nose, and throat physicians.

Microvasculature of the Tympanic Membrane
Acta Oto-Laryngologica, 1991In order to investigate the blood flow of the tympanic membrane (TM) in various conditions, the microvasculature of the TM was observed by scanning electron microscope, using casting methods. Differences in vascular patterns between pars tensa and pars flaccida were observed, suggesting that vascular distribution in TM is closely concerned with the ...

Tympanic membrane ossification
The Journal of Laryngology & Otology, 1993Ossification of the tympanic membrane after myringoplasty is recorded for the first time. Myringoplasty was performed for closure of a perforation which followed the surgical treatment of Otitis media with effusion and had included the insertion of a long-term T-tube.

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.

Brain, 1985
Sensation from the tympanic membrane is generally believed to be mediated via at least four cranial nerves, some authors describing discrete territories for each of these nerves. The lack of critical evidence for independent sensory areas prompted a clinical study of tympanic membrane sensation in 32 patients having known cranial nerve deficits ...

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.

Adaptive immunity of the tympanic membrane
American Journal of Otolaryngology, 1981In a previous experiment an antiserum was developed in the rabbit from the lamina propria of the tympanic membrane of the guinea pig. In the present study 18 Hartley guinea pigs were used in an in vivo experiment in which the antiserum (RAGTM IgG) served passively to immunize the animals subjected to various forms of trauma to the right tympanic ...
