Fast Small‐Angle X‐Ray Scattering Tensor Tomography: An Outlook into Future Applications in Life Sciences

Small Methods, EarlyView.
This study reveals the future potential of SAXS tensor tomography at macromolecular X‐ray crystallography beamlines and life sciences applications. A new standard in fast data acquisition is set, allowing for up‐to 10x higher throughput. The measurements show mineralised collagen fibrils within the incus bone of the human auditory ossicle.

Microtia and cholesteatoma: Implications for the reconstructive surgeon

JPRAS Open, 2021
Summary: Infection after reconstructive surgery for microtia is a technical challenge. This can be a sign of cholesteatoma formation by entrapment of epithelium in the middle or outer ear, specifically when the patient does not respond to first choice ...

The Current Situation and Development of Endoscopic Ear Surgery in China

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Endoscopic ear surgery has been widely performed in China since 2015 due to the development and rapid popularization of endoscopic technology. Due to the relative shortness of the auditory meatus, only a fixed endoscope is required in many cases, rather than a motion similar to a nasal endoscope, and uncontrollable bleeding is virtually non ...

Cholesteatoma of the Clivus [PDF]

Skull Base, 2006
Cholesteatomas (central nervous system epidermoids) can be found intradurally or extradurally in the central nervous system. Extradural intraosseous lesions are most commonly found in the petrous bone. The authors describe a unique case of a clival cholesteatoma in a 64-year-old woman who presented with headaches.

Ergonomics of 3D‐Exoscope Versus the Operating Microscope in Otologic Surgery

ANZ Journal of Surgery, EarlyView.
Microscope use in otologic surgery is associated with a high degree of ergonomic risk and musculoskeletal pain. A prospective comparative study was undertaken demonstrating a 3D‐exoscope has improved ergonomics compared to the operating microscope. Ongoing development is required to improve the ergonomics in otologic surgery on a larger scale. ABSTRACT

Defining the Terminology for Acute Ear Discharge in Children: Systematic Review and Expert Consensus Using the Nominal Group Technique

Clinical Otolaryngology, EarlyView.
ABSTRACT Background Acute otitis media (AOM) is one of the most frequent paediatric infections. In approximately 15% of children with AOM, the tympanic membrane perforates, leading to ear discharge. This subset of children is usually more unwell and may need different treatment than those without a perforation.

Patient's Perspective and Change in Quality of Life After Stapes Surgery: A Multicenter Prospective Trial

Otolaryngology–Head and Neck Surgery, Volume 173, Issue 3, Page 697-704, September 2025.
Abstract Objective This study evaluated outcomes of stapes surgery in otosclerosis patients by assessing audiometric results and health‐related quality of life (HRQOL) using the Dutch Stapesplasty Outcome Test‐25 (SPOT‐25) questionnaire. Additionally, the role of SPOT‐25 in preoperative decision‐making and as a follow‐up tool was explored.
