Delayed Unilateral Eagle Syndrome with Fractured Styloid Process.

Abstract

Purpose: Minor injury to head and neck is usually neglected for potential neurological consequences. We report a woman who suffered left Eagle syndrome due to styloid process fracture two years after a minor motorcycle collision.

Case report: A 53-year-old woman complained pain at her left upper neck, lower face and periauricular area after minor motorcycle collision at 2 years ago. The pain usually occurred spontaneously but was occasionally triggered or exacerbated by specific postural changes, including looking up or turning head to right side. Moreover, a foreign body sensation occurred at throat during swallowing. Physical examination provoked pain at the left submandibular area. Carotid bruit was absent. Otherwise, other neurological function was preserved. Computerized tomography revealed linear fracture at the middle of left styloid process. After inform, patient preferred conservative treatments including abortive non- steroidal anti-inflammatory drugs and an avoidance of rapid head rotations. Since afterwards, the frequency and intensity of neck pain greatly decreased and she could tolerate and maintain a normal daily living.

Conclusions: Asymptomatic or paucisymptomatic styloid process fracture may be neglected in case of minor injury to head and neck. A careful evaluation of neck should be completed in traumatic individuals to reveal underlying damage and prevent further harmful consequence.
