Middle Ear Virtual Endoscopy in Malleus Fracture and Dislocation
Ossicular injury is a frequent complication of head trauma and temporal bone fractures. An isolated fracture of the malleus with lateral dislocation of the manubrium is extremely rare. High-resolution computed tomography is the method of choice for evaluation of ossicular trauma. Virtual endoscopy (VE) is a novel technique that provides a realistic surface rendering of various organs that can b...
متن کاملA study of sound transmission in an abstract middle ear using physical and finite element models.
The classical picture of middle ear (ME) transmission has the tympanic membrane (TM) as a piston and the ME cavity as a vacuum. In reality, the TM moves in a complex multiphasic pattern and substantial pressure is radiated into the ME cavity by the motion of the TM. This study explores ME transmission with a simple model, using a tube terminated with a plastic membrane. Membrane motion was meas...
متن کاملEffect of cochlear implant electrode insertion on middle-ear function as measured by intra-operative laser Doppler vibrometry.
HYPOTHESIS The aim of this study was to investigate the impact of cochlear implant electrode insertion on middle-ear low frequency function in humans. BACKGROUND Preservation of residual low frequency hearing with addition of electrical speech processing can improve the speech perception abilities and hearing in noise of cochlear implant users. Preservation of low frequency hearing requires a...
متن کاملSimulations and Measurements of Human Middle Ear Vibrations Using Multi-Body Systems and Laser-Doppler Vibrometry with the Floating Mass Transducer
The transfer characteristic of the human middle ear with an applied middle ear implant (floating mass transducer) is examined computationally with a Multi-body System approach and compared with experimental results. For this purpose, the geometry of the middle ear was reconstructed from μ-computer tomography slice data and prepared for a Multi-body System simulation. The transfer function of th...
متن کاملLaser Doppler Vibrometry measurements of human cadaveric tympanic membrane vibration
OBJECTIVE To determine the feasibility of measuring tympanic membrane (TM) vibrations at multiple locations on the TM to differentiate normal eardrums from those with associated ossicular pathologies. DESIGN Cadaveric human temporal bone study. SETTING Basic science laboratory. METHODS A mastoidectomy and facial recess approach was performed on four cadaveric temporal bones to obtain acce...
