Hyoid Bone Syndrome [H.B.S.] and Styloid Process Syndrome [St P.S.] clinical presentation, diagnosis, and management

ABSTRACT

Both St.P.S. and H.B.S. involve pain in the anterolateral part of the upper neck radiating to the ear. In this study, fourteen patients were presented with St.P.S. and 74 patients were presented with H.B.S. The key for diagnosis of these syndromes was the palpating finger for a tender tip of the hyoid bone in H.B.S. or an elongated styloid process in St.P.S. Radiology had a confirmatory role in diagnosis of St.P.S, and a limited role in diagnosis of H.B.S. Both syndromes occurred in recurrent acute or chronic persistent forms. Conservative management was the treatment of choice in H.B.S., whereas surgery was the treatment of choice in St P.S. Clinical presentation, pathogenesis, and management plans of both syndromes were discussed
