ABSTRACT Background Conductive hearing loss requires the surgeon to evaluate ossicular movement plan and execute surgery. An objective assessment of chain with laser vibrometry would likely improve results ossiculoplasty. Methods Minimally invasive intraoperative (MIVIB), a fast accurate technique, using continuous time‐domain signal that stimulates Med‐El FMT transducer attached malleus in temporal bone model, was used artificial fixation chain. Results Through this analysis method,...
Abstract Single-shot structured light profilometry (SLP) aims at reconstructing the 3D height map of an object from a single deformed fringe pattern and has long been ultimate goal in projection profilometry. Recently, deep learning was introduced into SLP setups to replace task-specific algorithm demodulation with dedicated neural network. Research on learning-based made considerable progress short amount time due rapid development general network strategies transferrable nature techniques...
Hypothesis: In the literature several surgical methods have been reported that aim to improve hearing in patients with isolated malleus fractures; however, it is still not clear which method gives best results. Background: this study, laser Doppler vibrometry (LDV) was used compare outcome of different on fractures fresh frozen human temporal bones. Methods: Fractured shafts defrosted bones were repaired bone cement, a prosthesis from cortical bone, or partial ossicular replacement (PORP)...
Density gradient ultracentrifugation (DGU) becomes increasingly important for the sorting of nanomaterials according to particles' density, hence structure and dimensions, which determine their unique properties, but further development this separation technique is hindered by limited precision with densities could be characterized. In work, we these position-dependent 2D wavelength-dependent IR fluorescence-excitation resonant Raman spectroscopy measured directly in density after...
Abstract The avian middle ear differs from that of mammalians and contains a tympanic membrane, one ossicle (bony columella cartilaginous extra‐columella), some ligaments muscle. rim the eardrum (closing cavity) is connected to neurocranium and, by means broad ligament, otic process quadrate. Due limited number components in ear, possibilities attenuating conduction sound seem be activity stapedius We investigate what extent craniokinesis may impact because connection movable quadrate part...
In this paper we demonstrate the potential of stroboscopic digital holography and laser vibrometry as tools to gather vibration data validate modelling results in complex biomechanical systems, case avian middle ear. Whereas ear all mammal species contains three ossicles, birds only feature one ossicle, columella. Despite far simpler design, hearing range most is comparable mammals, adapted operate under very diverse atmospheric circumstances. This makes investigation potentially meaningful,...
Because the quadrate and eardrum are connected, hypothesis was tested that birds attenuate transmission of sound through their ears by opening bill, which potentially serves as an additional protective mechanism for self-generated vocalizations. In domestic chickens, it examined if a difference exists between hens roosters, given in vocalization capacity sexes. To test hypothesis, vibrations columellar footplate were measured ex vivo with laser Doppler vibrometry (LDV) closed maximally...
Background: A significant number of adults suffer from conductive hearing loss due to chronic otitis media, otosclerosis, or other pathologies. An objective measurement ossicular mobility is needed avoid unnecessarily invasive middle ear surgery and improve outcomes. Methods: Minimally intraoperative laser vibrometry provides a method that compatible with surgery, where the tympanic membrane elevated. The ossicles were driven by floating mass transducer their was measured using Doppler...
