Modeling sound transmission of human middle ear and its clinical applications using finite element analysis

open access: yesKaohsiung Journal of Medical Sciences, 2013
We have developed a new finite element (FE) model of human right ear, including the accurate geometry of middle ear ossicles, external ear canal, tympanic cavity, and mastoid cavity.

Cerebrospinal Fluid Leak During Stapes Surgery: The Importance of Temporal Bone CT Reconstructions in Oblique Anatomically Oriented Planes

open access: yesEar, Nose & Throat Journal, 2023
Stapes gusher is a massive flow of perilymph and cerebrospinal fluid leak that fills the middle ear immediately after surgical opening of the labyrinth, such as during stapedectomy.

Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

open access: yesJournal of Anatomy, EarlyView.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

Traumatic Stapes Luxation into the Vestibule

open access: yesEar, Nose & Throat Journal
We report a rare case of traumatic stapes luxation into the vestibule. A 31-year-old female visited an emergency room with sudden onset of vertigo and conductive hearing loss after accidental penetrating injury to the right ear.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Transcanal Endoscopic Stapes Surgery

open access: yesB-ENT, 2022
Stapes surgery is traditionally based on microscopic approach. For several years, endoscopy developed from a combined approach as a complementary device to microscope to an exclusive transcanal approach in various fields of ear surgery.

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

open access: yesThe Laryngoscope, Volume 136, Issue 8, Page 3559-3568, August 2026.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

Comparison of Manual Versus Robot‐Assisted Piston Prosthesis Placement and Crimping in a 3D‐Printed Temporal Bone Model

open access: yesLaryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.
ABSTRACT Objectives To reduce operator‐dependent variability and improve surgical precision, robot‐assisted piston prosthesis placement and crimping during otosclerosis surgery may represent a promising approach. However, dedicated microsurgical forceps for this application are not yet available in clinical practice.

Microscopic versus endoscopic stapes surgery—a meta-analysis study

open access: yesThe Egyptian Journal of Otolaryngology
Background The traditional approach for viewing middle ear structures during ear surgery is still the microscope, which provides both hands’ flexibility and binocular vision.
