Summary: The middle ear is an interface between air and fluid in terrestrial vertebrates. Contrary to traditional views, it is suggested that the middle ear functions through an impedance-matching mechanism rather than an impedance transformer. Acoustico-mechanical measurements of middle ear function and the development of middle ear models have contributed to this understanding.

Summary: Investigators in fish bioacoustics used to classify fishes as hearing generalists or specialists based on their hearing bandwidth and sensitivity. However, as understanding of fish hearing mechanisms grew, these terms became insufficient due to the existence of gradations in hearing capabilities. This paper proposes the resurrection of the terms specialist and non-specialist, but with modifiers to specify the particular functional structure considered as a specialization. It also highlights the importance of other aspects of fish hearing, such as sound source localization and discrimination, in addition to increased bandwidth and sensitivity.

Summary: ObjectiveAttic retraction pockets were reconstructed according to the grade. The surgical management based on the grade showed good outcomes in terms of the stability of the tympanic membrane, middle ear, and hearing.

Summary: This study reviewed surgical data of 57 CMEC patients and found that the Nelson staging system was more suitable for advanced CMEC cases, while the application of the Potsic staging system was limited by the rarity of Potsic stage II cases. The authors recommended a modified Nelson staging system to subdivide cases based on the erosion of ossicles and structures out of the middle ear.

Summary: The study aimed to analyze and compare the early and late post-operative results of GIBC used in ossiculoplasty. Audiometric findings of 40 patients were analyzed and it was found that there were significant improvements in hearing in the early post-operative period, while no significant changes were observed in the late post-operative period. The study concluded that GIBC is a safe and reliable material for ossiculoplasty, maintaining its ability to conduct sound in the long-term follow-up.

Summary: Acoustic communication is crucial for mate localization and selection in most anuran amphibians. However, true toads tend to lose parts of the middle ear apparatus, resulting in reduced sensitivity to high-frequency sounds. This study aims to investigate middle ear development in a toad species with well-known natural history and acoustic communication behavior. The findings suggest that middle ear development depends on the size of the toad rather than its age.

Summary: In this study, a commercial SD-OCT was used to evaluate the anatomy and sound-induced vibrations of the middle ear in humans. The results showed that SD-OCT technology provides high-resolution 3D images of the tympanic membrane and ossicles, as well as measurements of middle ear sound transmission. Therefore, SD-OCT has the potential to revolutionize the point-of-care assessment of middle ear disruptions leading to CHL.

Summary: The study revealed the significant role of middle ear ligaments in sound transmission, showing that severing both main ligaments can significantly impact auditory sensitivity and the position of the ossicular chain.

Summary: The paper focuses on modelling and analyzing the middle ear with an implantable hearing device. It specifically examines the electromechanical coupling between the biomechanical subsystem of the middle ear and the electrical subsystem of the implant, which generates new resonances, instabilities, subharmonic, and chaotic vibrations. Numerical results are compared with experimental findings on human temporal bones to improve the design of the implant.

Summary: This study uses a non-linear model of the human middle ear to investigate the efficacy of a middle ear implant, with a focus on the impact of floating mass transducer fixation on ear system dynamics and sound transfer to the inner ear. The stiffness characteristic of the coupler plays a key role in stapes excitation, and can cause polyharmonic and chaotic motion of the stapes and the transducer. Recommendations are provided on how to avoid polyharmonic and irregular oscillations in the system.

Summary: This study provides a detailed description of the ear ossicles in badgers, including the malleus, incus, and stapes, with anatomical and morphometrical data. Due to limited morphological data on middle ear anatomy of this species, the paper attempts to provide a complete set of standardized metrical data and comparative features regarding the auditory ossicles in badgers.

Summary: This study described the morphological and morphometric features of the auditory ossicles in red foxes and provided important geometric data through analysis. The results showed that the anatomical organization of the auditory ossicles in red foxes is similar to that in other animals, which contributes to the field of auditory biology.

Summary: Osteopetrosis is a rare inherited bone disease that results in increased bone mass and density, as well as hearing loss. A study found that a mutation in the CCDC154 gene can cause congenital deafness in mice, characterized by abnormal bony remodeling in the otic capsule.

Summary: In this study, it was found that vitamin D receptor deficient mice exhibited hypomineralization in the auditory ossicles, which was partially prevented by a calcium-rich diet. These findings suggest new treatment strategies for conductive hearing loss and underscore the importance of ossicle mineralization during development for normal hearing function.

Summary: This study retrospectively evaluated the clinical features and outcomes of 59 adult patients with middle-ear granulation pathologies associated with attic retractions. Low-pitched tinnitus was the principal complaint, and surgical intervention was effective in significantly improving the symptoms of tinnitus.
