Article Synopsis
- The study aimed to analyze gene expression in the middle ear mucosa of two patients with eosinophilic otitis media.
- One patient, who experienced severe hearing loss, had elevated levels of genes related to IL-5 and IL-33 receptors.
- These findings suggest a potential link between specific gene expressions and the severity of symptoms in eosinophilic otitis media.
Objective: Cochlear implantation (CI) for the treatment of single-sided deafness (SSD) is a relatively new treatment modality. Although comparing the effectiveness of CI and contralateral routing of signal (CROS) hearing aids (HAs) is important, very few reports on this topic exist. In this study, objective assessments and subjective assessments were conducted to determine which SSD individuals would prefer CI or CROS HAs.

However, the outcomes vary from case to case. Communication mode has been reported in many studies as the factor that related to the post CI outcomes.

Objective: Eosinophilic otitis media (EOM) is an intractable middle ear disease recognized by an eosinophil enriched middle ear effusion and mucosa. Although precise pathogenesis of EOM remains unclear, it is characterized by type 2 inflammation. Since IgG4 is an IgG subclass induced by type 2 cytokines such as IL-4 and IL-13, we sought to characterize and compare local IgG4 expression in patients with and without EOM.

Aims/objectives: To evaluate the benefits of the use of the Vibrant Soundbridge (VSB) for UCAA by performing audiometric and sound localization tests.
Materials And Methods: Four children with UCAA underwent VSB (VORP 503) implantation from 2018 to 2019.
