Endoscopic stapedectomy our experience [PDF]

, 2012
Stapedecomy traditionally is performed using operating microscope. Eventhough it is a time tested procedure, it had its own draw backs. In patients with excessive bony overhang it would bedifficult to access the middle ear cavity using operating ...

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

The Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Use of porcine small intestinal submucosa for pediatric endoscopic tympanic membrane repair

World Journal of Otorhinolaryngology-Head and Neck Surgery, 2017
Tympanic membrane perforationsoccur frequently in children, and can result in hearing loss, otorrhea, pain, and cholesteatoma. Due to the narrower ear canal in children, a postauricular incision is often needed to access the tympanic membrane for ...

Ultrastructural alterations of the tympanic membrane in retraction pockets from patients with chronic otitis media

Polish Journal of Pathology, 2021
Chronic otitis media with a retraction pocket is one of the forms of chronic otitis media that predisposes to cholesteatoma. The aim of our study was to determine the extent and type of changes in the tympanic membrane fragments which were surgically ...

Flexibility within the middle ears of vertebrates [PDF]

, 2012
Introduction and aims: Tympanic middle ears have evolved multiple times independently among vertebrates, and share common features. We review flexibility within tympanic middle ears and consider its physiological and clinical implications.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

Exploring Cerumen as an Alternative Matrix for Drug Detection and Quantification: Method Development and Application in Clinical Samples

Drug Testing and Analysis, EarlyView.
An LC–MS/MS method was developed for the detection of 33 psychoactive medications in cerumen (earwax) and applied to the samples of 60 psychiatric inpatient volunteers. The findings highlighted the utility of cerumen as an innovative biospecimen in clinical toxicological analysis.

Topical treatment of equine aural plaques with nitric acid and zinc solution

Equine Veterinary Journal, EarlyView.
Abstract Background Equine aural plaque caused by equine papilloma viruses is common worldwide and affected horses can show severe clinical signs. Due to its viral aetiology, in some countries affected horses are not allowed to compete. Since lesions persist, showing no spontaneous regression, effective and safe treatment is required.
