Radiologic Evaluation of the Stylohyoid Syndromes

Abstract

The stylohyoid syndromes are a constellation of head and neck pain syndromes that are associated with an elongated styloid process or ossified stylohyoid chain. The reported prevalence of the syndrome varies widely between 1.4% and 30%. The clinical features are subtle and patients are frequently misdiagnosed. The clinician may be guided to the correct diagnosis by history and physical examination, but the condition is confirmed on radiographic investigations. We review the radiologic features associated with the stylohyoid syndromes.
