Incidental finding of a neuroendocrine neoplasm in a suspected ear canal exostosis

Otolaryngology Case Reports, 2022
A 55-year-old man was referred to the Department of Otorhinolaryngology with a five-month history of progressive conductive hearing loss associated with a tumor in the external auditory canal. A temporal bone computed tomography (CT) revealed a bony growth covered by a thickened layer of soft tissue compatible with an exostosis. The suspected exostosis

Core collapse supernova remnants with ears [PDF]

, 2016
We study the morphologies of core collapse supernova remnants (CCSNRs) and find that about third of CCSNRs in our sample have two opposite `ears' protruding from their main shell. We assume that the ears are formed by jets, and argue that these properties are compatible with the expectation from the explosion jet feedback mechanism (JFM).

Late onset middle ear neuroendocrine tumor presenting with distant metastasis

Otolaryngology Case Reports, 2021
Tumors of the ear with neuroendocrine features are a very rare group of neoplasms, with neuroendocrine adenoma representing the more frequent entity found; the prevalence of middle ear neuroendocrine tumors is so low that it has never been determined ...

A rare case of multiple paragangliomas in the head and neck, retroperitoneum and duodenum: A case report and review of the literature

Frontiers in Endocrinology, 2023
Pheochromocytomas and paragangliomas (PGLs) are rare non-epithelial neuroendocrine neoplasms of the adrenal medulla and extra-adrenal paraganglia respectively. Duodenal PGL is quite rare and there are only two previous reports.

A Link Loss Model for the On-body Propagation Channel for Binaural Hearing Aids [PDF]

Antennas and Propagation, IEEE Transactions on , vol.61, no.12, pp.6180,6190, Dec. 2013, 2013
Binaural hearing aids communicate with each other through a wireless link for synchronization. A propagation model is needed to estimate the ear-to-ear link loss for such binaural hearing aids. The link loss is a critical parameter in a link budget to decide the sensitivity of the transceiver.

The use of the «Surgitron» radiowave scalpel for the surgical treatment of external ear neoplasms

Vestnik otorinolaringologii, 2016
The objective of the present study was to elucidate etiology and clinical picture of the tumours of the external ear as well as to evaluate the effectiveness of their radiowave surgery. We sought to optimize the surgical strategy for the treatment of tumour-like masses, benign and malignant neoplasms of the external ear with the use of the Surgitron ...
