UNLABELLED This study aimed at describing an alternative surgical technique to the insertion of a ventilation tube in the tympanic membrane: myringotomy by radiofrequency alone and associated with mitomycin C. AIM to show a surgical approach that can be simple to execute, not subject to complications arising from the ventilation tube. MATERIALS AND METHODS we compared myringotomy by microkn...

Hearing impairment is one of the most common disabilities. Animal models have been shown to be valuable tools in auditory research, including studies of middle-ear mechanics. Rats are potentially very useful for this purpose. They are low in cost, they are genetically similar to humans, and the middle-ear structures are easily approachable. The goal of the present study is to characterize the f...

The middle ear ossicles are important due to transmission of sound to the inner ear leading to sound understanding. The aim of present study was to determine the anatomical and morphometrical aspects of middle ear ossicles in Makouei sheep fetuses. For this experimental study, eight sheep fetuses at the age of 2 to 3 months were provided from public slaughterhouse; their middle ear ossicles wer...

In this study lateral differences in tympanic membrane temperature (T(Ty)) were explored as a correlate of either impulsive or cautious responding in Go-No-Go tasks. Thirty-two women and men performed two sustained attention to response tasks (Go-No-Go tasks). Those with warmer right in comparison to left tympanic membranes were more cautious, and those with warmer left in comparison to right t...

A 40-year-old male presented with a cholesterol granuloma of the petrous apex manifesting as progressive hearing loss and tinnitus. The lesion was treated via an extradural middle cranial fossa approach employing a new procedure to establish a drainage pathway into the superior tympanic cavity which preserved his hearing. The pathway was formed by a groove 5 mm wide and deep in the anterolatera...

Although gradual changes in air pressure may result in rupture of the tympanic membrane, this most often occurs from a rapid change. Sudden forceful blows on the ear, which seal the external auditory meatus, can result in sufficient increase in the air pressure in the ear canal to rupture the tympanic membrane. The most frequent single cause is a blow on the ear, usually with the open hand. Thi...

The use of tympanic thermometry is attractive in primary care, but a recent systematic review highlighted the paucity of data comparing tympanic thermometry with conventional methods. We report a study of 94 preschool children presenting to primary care in the United Kingdom (UK) with acute cough in whom tympanic infrared and axillary mercury thermometry are compared. Infrared thermometry showe...

Jugulo-tympanic paragangliomas are rare benign tumors arising from the neuroectodermal cells of tympanic cavity and dome jugular vein. Surgical resection has long been first-line treatment. However, when this is not possible, radiotherapy remains a therapeutic alternative allowing local control with less morbidity. We report case patient an unresectable tympano-jugular paraganglioma, symptomala...

BACKGROUND Tympanosclerosis is a pathological process involving the middle ear. The hallmark of this disease is the formation of calcium deposits. In the submucosal layer, as well as in the right layer of the tympanic membrane, the calcium deposits result in a significant increase in the activity of fibroblasts and deposition of collagen fibers. OBJECTIVES The aim of our study was to examine ...
