Pathology · patient case question
What is the most likely diagnosis?
Patient case: Pain every time he turns his head
Patient: Male, 48 years old
Chief Complaint: “I get a sharp pain in the side of my throat every time I turn my neck.”
Background: Tonsillectomy six years ago. No trauma. Analgesics give partial relief. Previously assessed for a temporomandibular disorder without benefit.
Vital Signs: BP 124/80 mmHg · HR 72 bpm
Findings: Pain on rotation of the head and on swallowing, radiating to the ipsilateral ear. Palpation of the tonsillar fossa reproduces the pain exactly. Jaw opening is 48 mm and painless; masticatory muscles are non-tender. The panoramic radiograph shows a long, slender, mineralised spine running downward and forward from the skull base.
Show answer and explanation
Correct answer: C. Eagle syndrome
- A. Sternocleidomastoid myofascial pain does produce referred pain to the ear and jaw and worsens with head movement, so it is a fair differential — but it is reproduced by palpating trigger points in the MUSCLE BELLY, not deep in the tonsillar fossa, and it has no radiographic correlate.
- B. Trigeminal neuralgia is a paroxysmal, electric-shock pain in a V2 or V3 distribution, set off by a cutaneous trigger zone during light touch, shaving or chewing. It is not provoked by neck rotation and does not radiate as a persistent throat ache.
- C. CORRECT. EAGLE SYNDROME is symptomatic elongation of the styloid process (beyond roughly 30 mm) or mineralisation of the stylohyoid ligament. The CLASSIC form typically follows tonsillectomy and gives a dull, persistent pharyngeal pain radiating to the ear, aggravated by swallowing, yawning and turning the head, and reproduced by digital palpation of the TONSILLAR FOSSA — all four features are present here. The STYLOCAROTID form arises when the elongated process impinges on the carotid sheath during head rotation. Panoramic or CBCT imaging confirms it.
- D. Internal derangement gives preauricular pain, clicking or limited opening, and pain that follows JAW function. This patient opens 48 mm painlessly with non-tender muscles, which argues firmly against it.
Note: Management runs from reassurance, analgesics and local steroid or anaesthetic infiltration to surgical styloidectomy by the transoral or transcervical route in refractory cases. Note that an elongated styloid process is a common incidental panoramic finding in asymptomatic people — the radiographic length alone is not the diagnosis; the clinical picture is.
