The pain was incompletely relieved by paracetamol and worsened by eating. He had no relevant medical history. At oral examination, a bony prominence was felt during left tonsillar fossa palpation. Orthopantomography was performed, showing an additional bone from the skull base to the hyoid bone (Fig E1 [online]). CT scan with three-dimensional reconstruction (Figure; Movies E1, E2 [online]) showed a 7.4-cm ossified stylohyoid complex on the left, merged with the homolateral lesser cornu of the hyoid bone. Eagle syndrome was diagnosed. The patient declined surgery. He received analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) during painful episodes. After 2 months follow-up, he remained satisfied with medical management.A 47-year-old man presented to the ear, nose, and throat surgery department with a 1-month history of intermittent pain, localized in left antero-latero-cervical and retromolar regions.

An elongated styloid process has a prevalence in approximately 4% of the population, among which approximately 4%–10% have symptoms. Eagle syndrome occurs more frequently in elderly women between 60 and 79 years of age. Neck CT scan is the reference standard for diagnosis. Eagle syndrome can be medically managed with analgesics, NSAIDs, and corticosteroid injections. When indicated, surgical removal through an intraoral or cervical approach can be used (1,2).Disclosures of conflicts of interest: A.R.T. No relevant relationships. S.B.
