A complete stylohyoid bone with a stylohyoid joint

Different clinical entities are associated with elongation of the styloid p rocess or ossification of the stylohyoid ligament. Although partial ossific ation of the stylohyoid ligament is not uncommon, complete ossification is rare. We present a rare case of complete ossification of the stylohyoid lig ament. This case may represent the extreme end of the spectrum of entities known as cervico pharyngeal pain syndrome, which includes Eagle's syndrome, stylohyoid syndrome, and pseudostylohyoid syndrome.
