[Manifestations of autoimmune disorders in otorhinolaryngology : Classical symptoms and diagnostic approach]. / Manifestationen von Autoimmunerkrankungen in der HNO-Heilkunde : Klassische Symptomatik und diagnostisches Vorgehen.

Manifestations of autoimmune disorders represent a diagnostic challenge. Many autoimmune disorders show typical manifestations in the ear, nose and throat and should be taken into account in the differential diagnosis. Sjogren's syndrome, various vasculitides and sarcoidosis represent the most common autoimmune disorders in otorhinolaryngology, but IgG4-related diseases, relapsing polychondritis and autoimmune disorders of the mucosa are also observed. Autoimmune diseases can lead to sensorineural deficits. Both hypo- and hyperthyroidism can be caused by autoimmune disorders. The diagnosis is usually based on the corresponding classification criteria, whose correct application can facilitate the clarification of these diseases.
