Design and modelling of a compliant constant-force surgical tool for objective assessment of ossicular chain mobility

Simon Nessim Henein, Charles Baur, Loïc Benoît Tissot-Daguette

Surgeons generally assess the mobility of the ossicle chain by manual palpation using rigid elongated hooks inserted through the ear canal. As the applied forces are in the range of a few grams equivalent force, the measurement remains subjective and its r ...

Inner ear cellular imaging through scattering bone

Demetri Psaltis, Marilisa Romito

Inner ear imaging is important for the assessment of hearing disorders. A major cause of hearing loss is the damage to the sensory hair cells, which are located inside the cochlea, a spiral-shaped bone in the inner ear. Imaging of intracochear hair cells i ...

Bulged Eardrum Detection From 3D Data

Pascal Frossard, Ivana Tosic, Sofia Karygianni

Bulging is a medical characteristic of the eardrum that is crucial for the diagnosis of acute otitis media. This work proposes a novel classification method for distinguishing bulged eardrums from non-bulged ones. The method uses novel key features extract ...

Characterization of a B16-F10 melanoma model locally implanted into the ear pinnae of C57BL/6 mice

Witold Waldemar Kilarski, Esra Güç

The common experimental use of B16-F10 melanoma cells focuses on exploring their metastatic potential following intravenous injection into mice. In this study, B16-F10 cells are used to develop a primary tumor model by implanting them directly into the ear ...

Surgical Anatomy of the Human Round Window Region: Implication for Cochlear Endoscopy Through the External Auditory Canal

Demetri Psaltis, Simon Nessim Henein

Objective: To enable development of an endoscope for cellular-level optical imaging of the inner ear. Study Design: A prospective study of 50 cadaveric human temporal bones to define detailed surgical anatomy of the round window (RW) region and the range o ...

Objective and subjective validation of an active control approach to reduce the occlusion effect in hearing aids

Hervé Lissek, Thomas Stefan Zurbrügg

The occlusion effect refers to the altered perception of one's own voice when the ear canal is fully or partially obstructed. Conventional countermeasures include the use of large vent bores or open fittings on the one hand and fittings reaching as deep as ...

Abrogation of HMX1 Function Causes Rare Oculoauricular Syndrome Associated With Congenital Cataract, Anterior Segment Dysgenesis, and Retinal Dystrophy

PURPOSE. To define the phenotypic manifestation, confirm the genetic basis, and delineate the pathogenic mechanisms underlying an oculoauricular syndrome (OAS). METHODS. Two individuals from a consanguineous family underwent comprehensive clinical phenotyp ...

Investigations on the physical factors influencing the ear canal occlusion effect caused by hearing aids

Hervé Lissek, Thomas Stefan Zurbrügg

The occlusion effect refers to the altered perception of one's own voice when the ear canal is fully or partially obstructed. While the loudness increase due to body conducted sounds requires an assessment by psychoacoustic methods, the ratio of sound pres ...

Active Control mitigating the Ear Canal Occlusion Effect caused by Hearing Aids

Thomas Stefan Zurbrügg

The World Health Organization (WHO) estimates the prevalence of a disabling hearing loss to be above 5% world-wide 1. A treatment with a hearing aid - be it behind-the-ear (BTE), in-the-ear (ITE) or receiver-in-canal (RIC) - involves some degree of occlusi ...

Normal Dendritic Cell Mobilization to Lymph Nodes under Conditions of Severe Lymphatic Hypoplasia

Melody Swartz, Joseph Rutkowski

To address the requirement for lymphatic capillaries in dendritic cell (DC) mobilization from skin to lymph nodes (LNs), we used mice bearing one inactivated allele of vascular endothelial growth factor receptor 3 (VEGFR3) where skin lymphatic capillaries ...
