Differential screen and treatment of sternocleidomastoid syndrome versus eagle syndrome: a case report

Background/PurposeDifferential screening is a complex process in chronic pain conditions. There is significant uncertainty that surrounds the pathophysiology of many chronic pain syndromes that may lead to misdiagnosis and treatment failures. Such differential screening is even more challenging where there is regional overlapping from surrounding tissues. This case report chronicles the differential screening and treatment of a patient with sternocleidomastoid syndrome (SCMS) originally diagnosed as Eagle's syndrome (ES).Case DescriptionA 55-year-old woman, referred to a physical therapist (PT) by an ear, nose and throat (ENT) physician with the diagnosis of ES. The patient complained of yearlong left-sided otalgia, blurred vision, excessive lacrimation, dysphagia, hyperesthesia on the left side of the face, unilateral temporal headaches, and both left mandibular and anterior neck pain.OutcomesThe PT examination revealed the patient did not exhibit hallmark findings for clinical confirmation of ES and instead demonstrated multiple signs consistent with SCMS.DiscussionManual therapy techniques and therapeutic exercises resolved the patient's year-long chronic symptoms within 6 sessions.
