Non-invasive assessment of biofilm growth in the middle ear using a portable low-coherence interferometry system
… them difficult to be recognized using a regular otoscope. However, lowcoherence interferometry (LCI) is capable of detecting and quantifying this microstructure. The goal of this research was to design a portable system integrating LCI with a standard video otoscope to detect the presence of …

A multispectral imaging method and device to detect and quantify the presence of fluid in the middle ear to facilitate the diagnosis and triage of ear infections
… we propose a multispectral visible - nIR otoscope that operates in the range of 600 nm - 1050 nm. We have performed experiments to demonstrate the proof of concept of our device on phantoms that includes, 3D printed middle ear structure, tympanic membrane made of silicone, and orange juice …

Non-invasive assessment of bacterial biofilm in the middle ear using low-coherence interferometry/optical coherence tomography and acoustic measurements
… LCI/OCT techniques with a standard video otoscope to provide depth-resolved optical scattering properties of the middle ear. An automatic algorithm was written to classify the LCI/OCT data to detect the presence of biofilm behind the TM and therefore distinguish the chronic infection. The …

Clinical translation of optical coherence tomography for the diagnosis of otitis media: validation and tracking of biofilms on the tympanic membrane and development of a novel automated classification and diagnostic platform
… the visual examination of the ear with an otoscope, this method provides limited quantitative information and relies on the skill level of the observer. Previous investigation of pediatric subjects using optical coherence tomography (OCT), a noninvasive cross-sectional imaging modality that …

Quantifying tympanic membrane dynamics in otitis media using low coherence interferometry
… a pneumatic low-coherence interferometry (LCI) otoscope was developed with automated pressure generation. The pneumatic LCI system developed during this research measures the TM displacement with an axial resolution of around 6.5 μm, and provides simultaneous pressure measurement in the ear …

Shortwave infrared imaging and its translation to clinically-relevant designs
… We describe the development of a medical otoscope and our clinical observations using this device to evaluate middle ear pathologies in both adult and pediatric populations, showing that SWIR otoscopy could provide diagnostic information complementary to that provided by conventional …

Design of multidimensional microplasma array for biofilm removal and dynamic photonic crystals
… biofilm, the microplasma jet array integrated-otoscope has been conceived and realized as an alternative to antibiotic treatment. For the first time, a non-drug based treatment for infectious ear biofilms is offhand for controlling the ear infectious biofilm. Furthermore, in combination with …

Design for Social Sustainability in Digital Fabrication for Development in the Global South
… conducted with three case studies: a 3D printed otoscope in Nepal; a digitally fabricated prosthesis in India; and, a digital fabricated suction pump machine in Kenya. The main study diverges in two directions, with the first part focusing on an analytical approach and the second part taking a …

Genetic aetiology of autosomal recessive non-syndromic hearing loss in sub-Saharan African patients: evaluation using targeted and whole exome sequencing
… African populations. Targeted Exome Sequencing (OtoSCOPE) The targeted genes, panel that included 116 genes, was able to resolve 7 of 9 families (77.8%) which were successfully sequenced, with one family failing to be sequenced. The causative variants identified in the 7 resolved families were : …
