Abstract

Earwax or cerumen is a substance secreted by the ceruminous and sebaceous glands of the ear canal. The main function of this biofluid is as a physical barrier, but its buildup can lead to earwax impaction and result in hearing loss. Optical coherence tomography (OCT) is one potential method for assessing earwax. A catheter-based OCT system with a handheld probe and custom-made 3D-printed specula was designed and used to non-invasively acquire cross-sectional and volumetric images of the canal of adult human subjects. Features relating to quantity, structure, texture, and optical attenuation were extracted and correlated back to subjects’ ear health.
