Middle Ear Papilloma

open access: yesBrazilian Journal of Otorhinolaryngology, 2007
Papillomas are benign, however locally invasive tumors normally originated in the larynx and nasosinusal tract. These tumors can be described from their specific histological and morphologic characteristics. Recurrence is common if excision is inadequately performed.

Non-invasive optical assessment of viscosity of middle ear effusions in otitis media

open access: yesJournal of Biophotonics, 2016
Eustachian tube dysfunction can cause fluid to collect within the middle ear cavity and form a middle ear effusion (MEE). MEEs can persist for weeks or months and cause hearing loss as well as speech and learning delays in young children.

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

3D finite element model of the chinchilla ear for characterizing middle ear functions

open access: yesBiomechanics and Modeling in Mechanobiology, 2016
Chinchilla is a commonly used animal model for research of sound transmission through the ear. Experimental measurements of the middle ear transfer function in chinchillas have shown that the middle ear cavity greatly affects the tympanic membrane (TM ...
