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 ...

A Novel Drug‐Loaded Porous Parylene Electrode for Targeted Anti‐Inflammatory Therapy and Hearing Preservation in Cochlear Implantation

open access: yesAdvanced Healthcare Materials, EarlyView.
A porous parylene‐coated electrode loaded with dexamethasone was developed to reduce inflammation after cochlear implantation. In guinea pigs, the device provided sustained drug release, maintained biocompatibility, improved auditory brainstem response thresholds, and reduced inflammatory cell infiltration and TNF‐α expression.

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 ...

A MIDDLE-EAR INSPIRATOR. [PDF]

open access: yesJournal of the American Medical Association, 1908
Tinnitis aurium, which is frequently an annoying and persistent sequel to acute and chronic Eustachian and middle ear catarrh, is often permanently relieved by inflation of the middle ear for a prolonged period. This is not generally appreciated and many patients find a prolonged course of office treatment prohibitive for lack of time or means.

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

open access: yesAdvanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...
