Eagle’s Syndrome (Elongated Styloid Process)

Eagle’s Syndrome (aka. stylohyoid syndrome, styloid syndrome, styloid–carotid artery syndrome)

Eagle’s Syndrome is an elongation of the styloid process.

The diagnosis is made by radiographic imaging and clinical signs.

DIAGNOSIS OF EAGLE’S SYNDROME AND TMJ DISORDERS (TMD)

Based on the author’s (Costantinides 2013) recommendation “when treating patients affected by temporomandibular disorders (TMD), complaining of atypical orofacial pain, and with a concomitant radiographic finding of a bilaterally elongated styloid, the possible coexistence of Eagle’s syndrome should always be considered.    When the clinician is faced with a patient complaining of chronic orofacial pain, the diagnostic pathway may be difficult. Considering that the clinical manifestations of Eagle’s syndrome resemble those of numerous other diseases, the patient often comes to the dental office after having visited other dentists or specialists, such as otolaryngologists (ENT), neurologists or maxillofacial surgeons, who have sometimes treated the symptoms without focusing on the diagnosis. Furthermore, Eagle’s syndrome may coexist and overlap with a TMD.
