Although 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.

A 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 SENSATION

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 ...

Microvasculature of the Tympanic Membrane

Acta Oto-Laryngologica, 1991
In 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 ...

Schwannoma of the tympanic membrane

The Journal of Laryngology & Otology, 2006
Schwannoma 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.
