Middle temporal artery flap in mastoid surgery

open access: yes, 2004
OBJECTIVE: The objective of this study was to describe the anatomy of the middle temporal artery (MTA) flap and its application in mastoid surgery. STUDY DESIGN: A description of the anatomy and surgical technique. CONCLUSION: The middle temporal flap is

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

open access: yesIntegrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

The Role of A Surgeon in Restoring the Senses & in Biomedical Engineering

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT This review is based on my 2025 Jepson Lecture and outlines my personal journey to restore hearing in people with a severe sensorineural hearing loss. My dream started as a 5‐year‐old as I told my kindergarten teacher when I grow up ‘I want to fix ears’ because my father is deaf. The journey resulted in a career in surgery followed by auditory

Aging in Autism: An Event-Related Potentials Study of Auditory Change Detection. [PDF]

open access: yesEur J Neurosci
Automatic change detection (MMN) and preattentional processes (P3a) have been studied in autistic children and young adults, but little is known about how they evolve during aging. We examined MMN and P3a in autistic and nonautistic adults aged 20–69 years. Results show that the neural mechanisms underlying automatic change detection and preattentional

Evaluation of the mastoid air cell system by high resolution computed tomography: three-dimensional multiplanar volume rendering technique

open access: yes, 2003
The mastoid air cell system is an important contributor to the pathophysiology of middle-ear inflammatory disease. The mastoid cavity is not only an air reservoir, but also an active space for gas exchange.

Sleep Preserves, Wake Differentiates: Strength‐Dependent Forgetting of Declarative Memories Across the Retention Interval

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep benefits memory, but the extend to which this benefit depends on initial memory strength remains heavily debated. We examined whether sleep preferentially stabilises weakly versus strongly encoded declarative memories, and whether classical sleep oscillations contribute to this effect.

Strong and Weak Episodic Memories Are Shaped by Multiple Cycles of NREM Spindles and REM Alpha Bursts

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Prior research has built up the notion that non‐rapid eye movement sleep (NREM) and rapid eye movement sleep (REM) are separately important for specific types of memory. However, growing evidence suggests that these sleep stages work in conjunction to jointly shape memory.

Otogenic Sigmoid Sinus Thrombosis Complicated by Cerebellar Abscess and Hydrocephalus: A Case Report [PDF]

open access: yesClin Case Rep
ABSTRACT A 44‐year‐old man developed otogenic sigmoid sinus thrombosis with cerebellar abscess, hydrocephalus, and recurrent posterior fossa infection. Staged neurosurgical drainage and canal‐wall‐down mastoidectomy achieved source control. Cultures were negative. Anticoagulant exposure was perioperative/early postoperative.
