Morphology and function of Neandertal and modern human ear ossicles. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance Middle ear ossicles are critical for audition and rarely preserved in fossils. Based on microcomputed tomography images, our comparative 3D shape analysis of Neandertal ossicles shows striking shape differences between Neandertals and anatomically modern humans (AMHs).

Morphometry of human ear ossicles
Archives of Medicine and Health Sciences, 2023 Background and Aim: Congenital anomalies and malformations of ear ossicles will cause hearing problems. Most commonly they will be either the absence of long process of incus or capitulum of stapes.

Comparison of sheep and human middle-ear ossicles: anatomy and inertial properties. [PDF]
J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2020 The sheep middle ear has been used in training to prepare physicians to perform surgeries and to test new ways of surgical access. This study aimed to (1) collect anatomical data and inertial properties of the sheep middle-ear ossicles and (2) explore ...

Uncovering the secreted signals and transcription factors regulating the development of mammalian middle ear ossicles. [PDF]
Dev Dyn, 2020 The mammalian middle ear comprises a chain of ossicles, the malleus, incus, and stapes that act as an impedance matching device during the transmission of sound from the tympanic membrane to the inner ear.

Morphological Variations of Middle Ear Ossicles and its Clinical Implications [PDF]
Journal of Clinical and Diagnostic Research, 2017 Introduction: The middle ear ossicles form a semi rigid chain in the middle of the ear for conduction and amplification of sound waves from the tympanic membrane to the inner ear.

Mechanical effect of reconstructed shapes of autologous ossicles on middle ear acoustic transmission
Frontiers in Bioengineering and Biotechnology, 2023 Conductive hearing loss is caused by a variety of defects, such as chronic otitis media, osteosclerosis, and malformation of the ossicles. In such cases, the defective bones of the middle ear are often surgically reconstructed using artificial ossicles ...

Growth pattern of the middle ear in the gray short-tailed opossum, Monodelphis domestica [PDF]
Vertebrate Zoology, 2022 We studied the mass growth trajectories of middle ear ossicles and tympanic membrane and oval window area in 19 specimens of postnatal ages 30–180 days of the gray short-tailed opossum Monodelphis domestica.

The Influence of Incudostapedial Joint Separation on the Middle Ear Transfer Function [PDF]
Clinical and Experimental Otorhinolaryngology, 2014 ObjectivesOne of the risks in middle ear surgery is high frequency hearing loss. It is believed that manipulations on the middle ear ossicles with the instruments may cause overstimulation of the inner ear and damage of the hear cells. Controversy arises
