Objectives: The degree of endolymphatic hydrops in Meniere's disease may be related to hearing loss. However, the results of prior studies have been inconsistent. We aimed to investigate the relationship between endolymphatic hydrops and hearing loss characteristics in Meniere's disease.
Methods: This study included 54 patients (62 ears) with Meniere's disease. Patients underwent three-dimensional real inversion recovery sequences for magnetic resonance imaging and pure-tone audiometry. Endolymphatic hydrops were assessed according to Gurkov's criteria (2011). Correlations between different degrees of endolymphatic hydrops and pure-tone audiometry, as well as staging, were analysed.
Results: Pure tone audiometry and staging were higher for vestibular endolymphatic hydrops complicated by cochlear ones than isolated cochlear or vestibular hydrops (both p < 0.05). There was no significant correlation between vestibular endolymphatic hydrops and pure-tonal audiometry or staging (all p > 0.05). The degree of hydrops in the middle turn was correlated with the mid-frequency hearing threshold (p < 0.05). The degree of cochlear hydrops was correlated with the audiometry, low-frequency hearing thresholds, mid-frequency hearing thresholds and staging (p < 0.01).
Conclusion: The types and sites of endolymphatic hydrops based on a 3D-real inversion recovery sequence can be used to indicate the degree of hearing loss in patients with Meniere's disease.
Level Of Evidence: Level III.

Background: Meniere's disease arises when an abnormal fluid accumulation results in heightened pressure within the inner ear or labyrinth. Its symptoms encompass vertigo, tinnitus, hearing loss, and a sensation of fullness in the ear. Various triggers for Meniere's disease are known, from smoking and alcohol consumption to recent viral illnesses, allergies, and anxiety.

Background: Familial Meniere's disease (FMD) is a rare polygenic disorder of the inner ear. Mutations in the connexin gene family, which encodes gap junction proteins, can also cause hearing loss, but their role in FMD is largely unknown.
Methods: We retrieved exome sequencing data from 94 individuals in 70 Meniere's disease (MD) families.

Objective: Endolymphatic sac tumors (ELSTs), as rare low-grade neoplasms, are primarily treated with surgery. This study analyzes the characteristics of tumor-infiltrating leukocytes (TILs) in ELSTs and their relationships with clinical features to explore the potential for immunotherapy in ELSTs.
Methods: Clinical data and tumor specimens of 10 ELSTs patients who underwent surgery were retrieved.
