A report of post-traumatic Eagle's Syndrome.

This paper reports the case of a 39-year-old woman who presented with symptoms of Eagle's Syndrome and an ossified stylohyoid ligament (SHL). Symptoms had developed immediately after trauma to the neck. No injury to the SHL was radiologically observable, but the causal relationship between the trauma and the occurrence of symptoms was evident. A new symptom of Eagle's Syndrome mimicking osteoathrosis of the temporomandibular joint was observed. The risk of misdiagnosis of temporomandibular disorders and the etiological role of neck trauma in Eagle's Syndrome are discussed.
