Early increased cell proliferation compensates subsequent hypoplasia of the ossicle [PDF]
Frontiers in Cell and Developmental BiologyOssicles are essential structures for normal sound conduction from the external environment to the inner ear. Proper formation of the ossicles is required for normal hearing, and ossicular deformities lead to hearing loss.

Evaluation of the ear ossicles with photon-counting detector CT. [PDF]
Jpn J Radiol, 2023 Recently, computed tomography with photon-counting detector (PCD-CT) has been developed to enable high-resolution imaging at a lower radiation dose. PCD-CT employs a photon-counting detector that can measure the number of incident X-ray photons and their

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.

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 ...

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

Are suspensory ligaments important for middle ear reconstruction?
PLoS ONE, 2021 As the resolution of 3D printing techniques improves, the possibility of individualized, 3-ossicle constructions adds a new dimension to middle ear prostheses.

Geometric and Morphometric Analysis of the Auditory Ossicles in the Red Fox (Vulpes vulpes)
Animals, 2023 The use of carnivores as experimental models in auditory biology has led to a significant improvement regarding our understanding of the structure and function of the ear.

Ear, Nose & Throat Journal, 2021 Objective: Chronic otitis media is a heterogeneous disorder. Chronic suppurative otitis media with cholesteatoma and, to a lesser extent, chronic otitis media with granulation lead to the destruction of bone structures within the middle ear.

The Stapes in Otosclerosis: Osteoarthritis of an Ear Ossicle
Head and Neck Pathology, 2021 Otosclerosis is a pagetoid proliferation of bone remodeling, vascular proliferation, bone resorption and new bone formation in the tympanic region of the temporal bone. The resulting anklyosis of the stapes footplate as it articulates with the oval window is the most common cause of conductive hearing loss in young to middle aged, predominantly ...

The Presence of the Human Auditory Ossicles—Detected Postmortem by CT Scan—As a Taphonomic Indicator
Forensic Sciences, 2023 Introduction: Three tiny bones compose the human ossicular chain: malleus, incus and stapes. Also known as auditory ossicles, they are united by joints in the middle ear cavity of the petrous part of the temporal bone.
