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 ...

Magnetically driven middle ear ossicles for optical measurement of vibrations in an ear with opened tympanic membrane

open access: yes, 2013
: Vibrations of the middle ear ossicles are easily measured by means of laser vibrometry. However, laser vibrometry requires free visual access to the object under investigation, and acquiring free visual access to the ossicles through the ear canal ...

DataSheet1_Mechanical effect of reconstructed shapes of autologous ossicles on middle ear acoustic transmission.PDF

open access: yes, 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 ...

Evaluation of Recurrence and Hearing Outcome for Inactive Squamosal Disease after Cartilage Strengthening Tympanoplasty

open access: yesInternational Archives of Otorhinolaryngology, 2022
Introduction Inactive squamosal disease is unique for having a conflicting treatment protocol, with an age-old debate between early surgical intervention or keeping patients in a long-term follow-up. The shifting paradigm is early intervention to prevent
