AN EXPERIMENTAL STUDY OF FOREIGN BODY REACTION IN THE MIDDLE EAR

Foreign body in the middle ear, a hearing aid complication.

A 12-year-old boy with moderate to severe bilateral mixed hearing loss was planned for hearing aid placement. During the process of making ear mould impression, the impression material accidentally entered the right middle ear. Removal of the ear mould impression was possible permeatally under general anaesthesia.

RHABDOMYOSARCOMA OF THE MIDDLE EAR IN AN ADULT

The authors present a case of embryonal rhabdomyosarcoma of the middle ear in an adult patient. Computerized tomography indicated a malignant tumor and the diagnosis was confirmed by pathological analysis.

An Experimental Study of Middle-ear Vibrations in Gerbils

RÉSUMÉ ABSTRACT The Mongolian gerbil has become increasingly popular in middle-ear research, as it is low in cost and has easily approachable middle-ear structures. The goal of this thesis is to present vibration measurements on the gerbil eardrum. Displacement frequency responses are acquired in five gerbils at three or four points along the manubrium and at up to 8 points on the eardrum. We u...

An Experimental Study of Middle-ear Vibrations in Gerbils

RÉSUMÉ The Mongolian gerbil has been widely used in middle-ear research, as it is low in cost and has easily approachable middle-ear structures. The goal of this study was to present vibration measurements of the gerbil tympanic membrane. A single-point laser Doppler vibrometer was used to measure displacement frequency responses in twelve gerbils at multiple points on the tympanic membrane. A ...
