Styloid chain ossification: Report of a case with articulations

A bilateral ossified stylohyoid ligament was observed in a cadaver specimen. On the left side, the stylohyoid chain was markedly enlarged. The stylohyoid ligament was completely ossified into two segments separated by a diarthrodial‐like joint. An articulation was also observed between the enlarged styloid process and the ossified ligament. On the right side, the styloid process had a normal appearance. The middle part of the stylohyoid ligament was ossified and it was attached to the styloid process and to the hyoid bone by a fibrous band. Proposed theories to account for the ossification oaf this ligament are discussed. Since the presence of an enlarged and ossified stylohyoid chain can cause much discomfort and pain, a greater understanding of the causative factors responsible for this anomaly is needed to provide for more effective diagnosis and treatment. © 1995 WiIey‐Liss, Inc.
