Parametric model of young infants’ eardrum and ear canal impedances supporting immittance measurement results. Part I: Development of the model

open access: yesActa Acustica, 2022
Wideband acoustic immitance (WAI) measurements provide an objective means to detect pathological middle ear conditions. However, for ears of young infants, it is still difficult to make clear statements about the middle ear status based on WAI ...

Neuroendocrine adenoma of the middle ear—An intriguing entity

open access: yesClinical Case Reports, 2021
Despite its rarity, the neuroendocrine adenoma of the middle ear (NEAME) is a differential diagnosis of the middle ear disease. We suspect that the NEAME is underdiagnosed and more cases can be detected through education and personal experience ...

Middle ear innovation in Early Cretaceous eutherian mammals

open access: yesNature Communications, 2023
The middle ear ossicles in modern mammals are repurposed from postdentary bones in non-mammalian cynodonts. Recent discoveries by palaeontological and embryonic studies have developed different models for the middle ear evolution in mammaliaforms ...

Middle Ear Barotrauma among Licensed Para-pilots of a Metropolitan City: A Descriptive Cross-sectional Study

open access: yesJournal of Nepal Medical Association, 2022
Introduction: Middle ear barotrauma is a tissue injury to the ear secondary to inadequate pressure equalisation between the middle ear and the external environment. Paragliding, though an exciting sport, has its own risks and hazards.

A Fully-Implantable Cochlear Implant SoC With Piezoelectric Middle-Ear Sensor and Arbitrary Waveform Neural Stimulation

open access: yesIEEE Journal of Solid-State Circuits, 2014
A system-on-chip for an invisible, fully-implantable cochlear implant is presented. Implantable acoustic sensing is achieved by interfacing the SoC to a piezoelectric sensor that detects the sound-induced motion of the middle ear. Measurements from human

High-Speed Holographic Shape and Full-Field Displacement Measurements of the Tympanic Membrane in Normal and Experimentally Simulated Pathological Ears

open access: yesApplied Sciences, 2019
To improve the understanding of the middle-ear hearing mechanism and assist in the diagnosis of middle-ear diseases, we are developing a high-speed digital holographic (HDH) system to measure the shape and acoustically-induced transient displacements of ...

Otitis media impacts hundreds of mouse middle and inner ear genes. [PDF]

open access: yesPLoS ONE, 2013
Otitis media is known to alter expression of cytokine and other genes in the mouse middle ear and inner ear. However, whole mouse genome studies of gene expression in otitis media have not previously been undertaken.
