Hyoid bone insertion tendinitis:: clinicopathologic correlation

Hyoid bone insertion tendinitis is often not taken into consideration in clinical practice and neglected in the differential diagnosis while evaluating patients with chronic neck pain. One of the main important reasons why physicians do not bear this entity in mind is that it has not been well described histopathologically. Two patients, who had been diagnosed and treated surgically for hyoid bone insertion tendinitis, were presented in this study. Microscopically, degenerative changes in the striated muscle tissue, which are characterized by myocyte necrosis, atrophy along with fibrosis and calcification in some foci, were observed. These findings provide evidence for the clinical picture of hyoid bone insertion tendinitis.
