[Pathogenesis of thyroalgia].

The authors analyze thyroalgias occurring in various thyroid diseases and diseases of the adjacent organs and tissues. They come to a conclusion that as far as thyroid diseases are concerned, true thyroalgias are the most incident in various thyroiditis forms, thyroid tumors, postoperative cicatrices, and are explained by the pathologic process impact on glandular capsule (stretching, intergrowth, pressure, etc.). Of diseases not directly related to thyroid but causing thyroalgias (pseudothyroalgias) laryngitis, pharyngitis, and osseous conditions are the most incident, which indirectly influence pain development. Pseudothyroalgias should be differentiated from such osseous changes in the neck as deforming spondylosis, spondylarthrosis, extra cervical ribs (a developmental abnormality), and structural specificities of temporal bone styloid processes.
