This is a rare case report of a foreign metallic body found in the middle ear. During the use of an electric welding by a metalworker, a glowing drop of dissolved metal overrun, burning the skin of his external auditory meatus, perforated the tympanic membrane and finally was implanted around the ossicles as a foreign body. Due to difficulty of the physical examination and the moderate symptoms...

The study was to analyze the dynamic characteristics of ossicles under the stimulus frequencies, 125 Hz, 250 Hz, 500 Hz, 750 Hz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 5 kHz, 6 kHz, 7 kHz and 8 kHz, by finite element method. The finite element model of the ossicles chain of patients could be built by 3D image model of the ossicles based on the high resolution computed tomography. The displacement at the f...

Aim of the study: The authors present a prospective histomorphological study of middle ear ossicles, harvested from cholesteatomous ears, to evaluate for presence of residual cholesteatoma after mechanical treatment and short-time autoclaving. Materials and methods: Sixty ossicles were used as specimens in this study. The ossicles were grouped as follows: Group A ossicles stripped and burred us...

tory canal. The external auditory canal then channels the vibration toward the eardrum, or tympanic membrane (TM). This in turn causes the eardrum to vibrate, which sets into motion the mechanical structures of the middle ear. The middle ear ossicles, or middle ear bones. These 3 tiny bones are attached to the TM and move as it moves. They transmit the sound waves further along the auditory cha...
