Otological IgG4-Related Disease With Inner Ear Involvement: A Case Report and Review of Literature

Immunoglobulin G4-related disease (IgG4-RD) is a chronic inflammatory disease involving multiple organs. Some studies have reported otological manifestations of IgG4-RD, although most studies describe involvement of the middle ear, and reports on inner ear manifestations are limited. Here, we describe a case of a 30-year-old man with IgG4-RD involving the inner ear. This case demonstrated that IgG4-RD affected the inner ear and caused cochlear ossification. Cochlear implants may be considered for milder cases, and hormone and immunosuppressive therapy may control disease progression.

Automated summary

This study describes a case of IgG4-related disease affecting the inner ear and causing cochlear ossification. Cochlear implants and hormone/immunosuppressive therapy can help control disease progression, especially in milder cases.
