In humans and other land vertebrates, a tube that links the pharynx to the cavity of the middle ear to allow the equalization of the pressure on both sides of the eardrum.
All 8 patients after radical operation had unpassable auditorytube.
2
Comprehensive morphological and functional evaluation of the auditorytube becomes possible within a single examination'.
3
It was impossible to obtain the image of the cartilage part of the auditorytube.
4
Non-contrast computer tomograms showed air in the lumen of the bone part of the auditorytube of all the examinees.
5
Conclusions: The introduced MRI protocol allow visualization of the opening of the auditorytube and provides detailed anatomical information of the nasopharynx.
6
Purpose: To develop and evaluate a protocol for the anatomic depiction and functional testing of the auditorytube with the use of MR imaging.
7
During the Valsalva test, opening of the auditorytube was demonstrated in 20 of the 22 investigated sides using the dynamic TFE single slice sequence.
8
By CT data, 14 of 17 patients with perforative OMPC had passable auditorytube even in aggravated inflammatory process, 3 of them had unpassable one.
