[Ear involvement in Wegener's granulomatosis]

Area of Science:

• Otolaryngology
• Rheumatology
• Immunology

Background:

• Wegener's granulomatosis (WG), now known as granulomatosis with polyangiitis (GPA), is a rare autoimmune disease characterized by inflammation of small to medium-sized blood vessels.
• WG/GPA can affect multiple organs, including the respiratory tract, kidneys, and ears.
• Otorhinolaryngological (ENT) manifestations are common in WG/GPA, with the ears being frequently involved.

Purpose of the Study:

• To review the existing literature on the inflammatory changes in the ears associated with Wegener's granulomatosis.
• To highlight the potential consequences of these inflammatory changes, specifically hearing impairment and deafness.

Main Methods:

• Literature review of studies concerning Wegener's granulomatosis and its otological manifestations.
• Analysis of reported cases and clinical findings related to ear involvement in WG/GPA patients.

Main Results:

• Inflammatory changes in the ears are a significant clinical manifestation of Wegener's granulomatosis.
• These changes can range from external ear involvement to middle and inner ear pathologies.
• Untreated or severe inflammation can lead to progressive hearing impairment and, in some cases, permanent deafness.

Conclusions:

• Ear involvement is a critical aspect of Wegener's granulomatosis that requires attention.
• Early diagnosis and management of otological symptoms in WG/GPA patients are crucial to prevent irreversible hearing loss.
• Further research is needed to understand the pathophysiology and optimize treatment strategies for WG/GPA-related hearing impairment.
