Intralabyrinthine Vestibular Schwannoma Responsive to Intratympanic Gentamicin Treatment [PDF]
, 2017 Intralabyrinthine schwannoma (ILS) is a rare benign tumor that affects the ends of cochlear and vestibular nerves. In a majority of the cases, it occurs with unilateral progressive sensorineural hearing loss.

Deep Learning-Based Inner Ear Subregion Segmentation in 3D T2-Weighted MRI Using Label-Preserving Data Augmentation. [PDF]
NMR BiomedA deep learning segmentation model was proposed for automated inner ear subregion segmentation using 3D T2‐weighted MRI. A transformer‐based model with label‐preserving data augmentation improves delineation of thin and complex structures such as the semicircular canals.

Journal of Ultrasound in Medicine, EarlyView.Chorionic villus sampling (CVS) is a crucial prenatal diagnostic tool, but a declining number of procedures makes training a challenge. Here we describe a transcervical CVS simulator made from ballistic gelatin. Ninety‐three Maternal‐Fetal Medicine providers used the simulators during hands‐on workshops and completed surveys regarding their fidelity ...

Superior Semicircular Canal Dehiscence in a Patient with Ehlers-Danlos Syndrome: A Case Report. [PDF]
, 2017 Superior semicircular canal dehiscence (SSCD) is a bony defect in the middle cranial fossa floor that results in an abnormal connection between the inner ear and cranial vault.

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 ...

Mesna in Otologic Surgery: Efficacy and Safety—A Scoping Review
The Laryngoscope, EarlyView.PRISMA flow diagram indicating the process of systematic inclusion and exclusion of articles. ABSTRACT Objective Mesna (Sodium 2‐mercaptoethanesulfonate) is widely used as a mucolytic agent and uroprotective agent. Recently, its disulfide bond‐breaking property has been applied in otologic surgery to facilitate safer dissection of cholesteatoma and ...

Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders
Frontiers in Neurology, 2014 We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD) Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best ...

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance
The Laryngoscope, EarlyView.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.
