Cervical spine radiographs revealed complete bilateral ossification of the stylohyoid ligaments as well as advanced ossification of the anterior longitudinal ligament (flowing hyperostosis) throughout the cervical and upper thoracic spine, abutting and displacing the prevertebral soft-tissues (Figures 1-3).
Elongated styloid processes or ossified stylohyoid ligaments can be palpated intraorally along the tonsillar pillars and radiographic imaging usually confirms the diagnosis.
Eagle's syndrome: a case of symptomatic calcification of the stylohyoid ligaments.
The styloid process may vary in length and sometimes stylohyoid ligament may also ossify from its origin at the styloid process to its attachment at the hyoid bone mimicking elongated styloid process.
Computed tomography (CT) of the neck with 3-dimensional reconstruction images was then obtained, which indicated that the patient had bilateral calcified stylohyoid ligaments to the level of the hyoid bone, with no other pathologic findings (figures 1 and 2).
Eagle Syndrome was first described in 1937 by Eagle as elongation of the styloid process causing pharyngeal pain, (1) and it is now thought to be an assemblage of symptoms resulting from elongation of the styloid process or progressive calcification of the stylohyoid ligament.
Eagle syndrome is a rare condition where elongated temporal styloid processes or calcified stylohyoid ligaments
are in conflict with the adjacent anatomical structures giving rise to a complex range of symptoms including otalgia dysphagia foreign body sensation in throat pain along carotid artery distribution and others.
Calcification of either one or both stylohyoid ligaments
has been associated with difficult laryngoscopy (17-19).
2) described callosities on both stylohyoid complexes and those were regarded as ossified attachments of stylohyoid ligaments
to corresponding styloid processes.
However, computed tomographic (CT) angiography demonstrated that the styloid processes were elongated and the stylohyoid ligaments
were calcified bilaterally (figure 1).
3) Nearly all of these calcified stylohyoid ligaments
are considered to be anatomic variants that are of no clinical concern.
Eagle's Syndrome is a rare clinical condition, which often presents with recurrent pain in the oropharynx and face, foreign body sensation in the throat, dysphagia and referred otalgia due to an elongated styloid process or calcified stylohyoid ligament
