Tympanic membrane changes in central tympanic membrane perforations
American Journal of Otolaryngology, 2005The objective of this study was to evaluate the histopathological changes in central tympanic membrane perforations caused by chronic otitis media without cholesteatoma.Twenty-nine temporal bones from 25 patients (13 male patients and 12 female patients) with central tympanic membrane perforations-18 chronic otitis media with perforation and 11 chronic

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 ...

Archives of Otolaryngology - Head and Neck Surgery, 1974
Specialized attachments have been designed and produced for the purpose of taking tympanic membrane photographs (Kowa RC 2 Fundus Camera). A doublespeculum technique made it possible to clean the ear canal of wax, hair, and loose canal epithelium through the mounted speculum.

Schwannoma of the tympanic membrane
The Journal of Laryngology & Otology, 2006Schwannoma arising from the tympanic membrane is a rare neoplasm. This report describes an external ear canal mass obscuring the tympanic membrane. A transcanal approach identified a tumour adhered to the tympanic membrane. The tumour was excised without myringoplasty. Pathology confirmed the diagnosis of schwannoma.

Biomechanics of the tympanic membrane
Journal of Biomechanics, 2011The tympanic membrane is a key component of the human auditory apparatus which is a complex biomechanical system, devoted to sound reception and perception. Over the past 30 years, various bioengineering approaches have been applied to the ear modeling and particularly to the middle part.

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,

Tympanic Membrane and Tympanic Plate [PDF]
, 1978 Since mammals descended from terrestrial forms and the overwhelming majority of them remained terrestrial, it is not surprising that the mammalian ear is a terrestrial one. The middle ear is therefore a device to match the acoustic impedances of air and the liquids in the inner ear.

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 ...
