Soft tissue reaction to ceramic ossicular replacement prosthesis

The Journal of Laryngology & Otology, 1985
AbstractSoft-tissue reaction to ceramic ossicular replacement prostheses (CORP) has been evaluated histologically in rabbits and humans. One week after implantation, severe inflammatory and foreign body reaction was observed in the fibrous connective tissue surrounding the prosthesis.

Micro‐CT informed cranial anatomy of the early rhynchosaur Howesia browni, with implications for rhynchosaur skull evolution

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Rhynchosaurs are unusual archosauromorph reptiles that lived between the Induan and early Norian (Early to early Late Triassic). They are characterized by their stocky build and broad skull with a beak‐like premaxilla. This rather charismatic configuration is most clearly expressed in Late Triassic hyperodapedontine rhynchosaurids.

Novel biological/biohybrid prostheses for the ossicular chain: fabrication feasibility and preliminary functional characterization [PDF]

, 2009
Alternatives for ossicular replacements were fabricated in order to overcome persisting rejections in middle ear prosthetization. Unlike the synthetic prostheses in fashion, we propose biological and biohybrid replacements containing extra cellular ...

Cambrian small shelly fossils from North Greenland (eastern Laurentia; Series 2, Stage 4) with regional and global correlations

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Cambrian Series 2 represents a key interval for documenting the evolution and diversification of early biomineralized skeletal animals. In this interval, small shelly fossils (SSF) provide an essential archive for regional biostratigraphy and intercontinental correlation.

Model-oriented Review and Multi-Body Simulation of the Ossicular Chain of the Human Middle Ear [PDF]

, 2012
The ossicular chain of the human middle ear has a key role in sound conduction since it transfers vibrations from the tympanic membrane to the cochlea, connecting the outer and the inner part of the hearing organ.

Classification of facial nerve aberration in congenital malformation of middle ear: Implications for surgery of hearing restoration

Journal of Otology, 2018
Objectives: Facial nerve aberration is the most troublesome situation in congenital malformations of middle ear. The aim of our study is to investigate its imaging and clinical features as well as relevant choice of surgical techniques for hearing ...

A giant plagiosaurid temnospondyl from Bjørnøya (Svalbard, Norway) and the origin of the plagiosaurid body plan

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract An articulated temnospondyl skeleton from Middle Triassic deposits of Bjørnøya (Bear Island) in the western Barents Sea is described as a new plagiosaurid genus and species, Arctobatrachus urdensis. With a body length well exceeding 2 m, it represents by far the largest known member of the Plagiosauridae.

Good Manufacturing Practices-grade Preformed Ossicular Prostheses from Banked Bone via Computer Numerically Controlled Micromilling [PDF]

, 2011
Objectives: The aim of this study was the fabrication of ossicular replacement prostheses (ORPs) from decellularized banked cortical bone via computer numerically controlled (CNC) ultraprecision micromilling, in order to obtain preformed clinical-grade

Comparative Cochlear–Vestibular Aging Reveals Age‐Aligned Mitochondrial Ultrastructural Burden, Mitophagy–Autophagy Remodeling, Synaptic Uncoupling, and Sensory Functional Decline

Aging Cell, Volume 25, Issue 7, July 2026.
This study maps age‐aligned cochlear and vestibular decline in SAMP8 mice, linking functional impairment with synaptic vulnerability, mitochondrial ultrastructural injury, and autophagy/mitophagy–lysosome transcriptional remodeling. The findings provide an integrated framework for understanding shared inner‐ear aging trajectories.
