Noncholesteatomatous Cyst of the Tympanic Membrane: A Nonpublished Entity?
Case Reports in Otolaryngology, 2015 Introduction. The presence of a serous cyst in the tympanic membrane implies the description of a new or unpublished entity based on our knowledge whose origin may be very unlikely explained on actual embryologic and anatomic background.

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]
, 2017 Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

Optical Coherence Tomography as an Emerging Technique for Identifying Pediatric Middle Ear Effusion
The Laryngoscope, EarlyView.This prospective study evaluated optical coherence tomography (OCT) as a diagnostic tool for identifying middle ear effusion (MEE) in 164 pediatric patients. OCT was determined to have a sensitivity of 74% and a specificity of 93%, comparable to otoscopy and tympanometry, with moderate agreement (κ = 0.41) between clinical and non‐clinical raters.

Energy localisation and frequency analysis in the locust ear [PDF]
, 2013 Animal ears are exquisitely adapted to capture sound energy and perform signal analysis. Studying the ear of the locust, we show how frequency signal analysis can be performed solely by using the structural features of the tympanum.

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

Mastoid Surgery Does Not Normalize Tympanometric Middle Ear Pressure in Children With Cholesteatoma
The Laryngoscope, EarlyView.Conflicting mechanism‐based hypotheses have been used to promote selection of different approaches to management of the mastoid in order to optimize middle ear pressure homeostasis after removal of cholesteatoma. For example: (a) conservation of mastoid mucosa and opening of ventilation pathways endoscopically to normalize function, (b) removal of ...

Discovery of a lipid synthesising organ in the auditory system of an insect [PDF]
, 2012 Weta possess typical Ensifera ears. Each ear comprises three functional parts: two equally sized tympanal membranes, an underlying system of modified tracheal chambers, and the auditory sensory organ, the crista acustica.

The endocannabinoid/cannabinoid receptor 2 system protects against cisplatin-induced hearing loss [PDF]
, 2018 Previous studies have demonstrated the presence of cannabinoid 2 receptor (CB2R) in the rat cochlea which was induced by cisplatin. In an organ of Corti-derived cell culture model, it was also shown that an agonist of the CB2R protected these cells ...
