Eagle syndrome is a rare disease responsible for multiple head and neck symptoms, resulting from an elongation of the styloid process or ossification of the stylohyoid ligament compressing adjacent neurovascular structures. There are two variants, the classic one characterized mainly by pain and dysphagia and the carotid variant distinguished with pain and sometimes cerebral ischemia.

We describe a clinical case report of a 45-year-old female patient, who experienced left cervical pain, performing the complete myofascial pain protocol of the Regional Hospital "General Ignacio Zaragoza" ISSSTE in Mexico City, resulting in a 50 mm elongation of the styloid process in the CT scan, confirming the diagnosis, and focusing the article on the anatomical-surgical description.
