Autoimmunity and otolaryngology diseases

Many systemic autoimmune diseases have otolaryngology manifestations that could represent a diagnostic challenge for clinicians, as they often constitute an early sign of an otherwise asymptomatic autoimmune condition and may lead to delayed diagnosis and treatment. In other cases, otolaryngology manifestations can be overlooked in patients with previously diagnosed autoimmune diseases. The pres- ence of concomitant conditions, the heterogeneity of studies available in the literature, and the lack of randomized trials are factors that may limit the prompt diagnosis of otolaryn- gology manifestations in systemic autoimmune diseases, with underestimation of the problem and undertreatment of the related condition.
