Styloid-stylohyoid syndrome in the differential diagnosis of atypical facial pain.

Differential diagnosis of atypical facial pain can be a perplexing problem. Similarities in symptomatology and nonspecific subjective findings make diagnosis difficult. The astute diagnostician, regardless of his speciality, must be acutely aware of key findings that will differentiate the myriad of chronic pain syndromes in his patients. Accurate correlation of clinical and radiographic findings in patients with "Eagle's syndrome" may assist the clinician in distinguishing this entity from other pain syndromes, such as glossopharyngeal or vagoglossopharyneal neuralgia.
