What is the function of the organ of Corti? The Cochlea: The ear is divided into three different parts. Basically, the outer ear is what we see, the middle ear is where the ear drum is located, and the inner ear is where the cochlea is located. The cochlea has an organ of corti ...
Tympanometry is a method for evaluation of the mobility of the ear drum and the functional condition of the middle ear. This is performed by measuring the ability of the tympanic membrane to reflect a probe tone in response to gradually changing air pressure in the ear canal. Four tympano...
However, in ears with a poor tubal function, a nonretracted, nonperforated drum was found with higher frequency in the palisade group. Decision matrix analysis showed that the last postoperative Valsalva maneuver was the best predictor of the drum condition at the reevaluation. The Eustachian ...
Displacement of the TM in the chick was measured at several frequencies between 70 and 120 dB SPL and was found to be linear. The results of displacement measured from the tip of the tympanum and from a location 1.0 mm more central on the drum membrane revealed a large difference in ...
The auditory canal is the part of the ear hole that can easily be seen when looking at an ear up-close. The sound waves pass through the auditory canal and reach the tympanic membrane, better known as the eardrum. Just like when a drum is hit by a drumstick, the thin sheet of ...

Assessment of eustachian tube functions in patients with ear drum perforation Tubal malfunction is the most important factor in the development and persistence of otitis media. When the eustachian tube malfunction persists, the most carefully performed surgery will fail because the initiating pathogenetic ...
No extrusion of the columella has been observed so far. Although pre-operative bone conduction deteriorated over the speech frequencies in 11 patients and at 4 000 Hz in 6, this process could also be observed in the non-operated ear. There was only 1 patient in whom a considerable ...
Size of Mastoid Air Cell System in Relation to Healing After Myringoplasty and to Eustachian Tube Function Ears with dry central ear drum perforation following chronic otitis media have been investigated. The sh of the mastoid air cell system has been determined... J.,Holmquist - 《Acta Oto ...
Contrast medium was instilled into the middle ear via a drumhead perforation and 1 scan/sec taken during swallowing. We classified ET function based on the presence or absence of a) movement of the cartilaginous portion, and b) contrast medium in the ET as i) movement present, contrast ...
