Endolymphatic Sac Tumor

Ear, Nose & Throat Journal, 2022
Masses occupying the retrolabyrinthine space are uncommon and most often represent paragangliomas, choroid plexus papilloma, endolymphatic sac tumors (ELSTs) or distant metastasis. ELSTs are rare, locally invasive tumors of the inner ear, with less than 300 cases reported in the literature.

Failure of fluid absorption in the endolymphatic sac initiates cochlear enlargement that leads to deafness in mice lacking pendrin expression. [PDF]

PLoS ONE, 2010
Mutations of SLC26A4 are among the most prevalent causes of hereditary deafness. Deafness in the corresponding mouse model, Slc26a4(-/-), results from an abnormally enlarged cochlear lumen.

Papillary‐cystic neoplasms of the middle ear are distinct from endolymphatic sac tumours

Histopathology, 2020
Papillary neoplasms of the middle and inner ear are rare and poorly characterised. The current World Health Organization classification divides them into two major subtypes: aggressive papillary tumours (APTs) and endolymphatic sac tumours (ELSTs).

A Synchrotron and Micro-CT Study of the Human Endolymphatic Duct System: Is Meniere's Disease Caused by an Acute Endolymph Backflow?

Frontiers in Surgery, 2021
Background: The etiology of Meniere's disease (MD) and endolymphatic hydrops believed to underlie its symptoms remain unknown. One reason may be the exceptional complexity of the human inner ear, its vulnerability, and surrounding hard bone.

Measurements From Ears With Endolymphatic Hydrops and 2-Hydroxypropyl-Beta-Cyclodextrin Provide Evidence That Loudness Recruitment Can Have a Cochlear Origin

Frontiers in Surgery, 2021
Background: Loudness recruitment is commonly experienced by patients with putative endolymphatic hydrops. Loudness recruitment is abnormal loudness growth with high-level sounds being perceived as having normal loudness even though hearing thresholds are
