Which ligament is associated with Ernest syndrome?

• A. Stylohyoid ligament
• B. Sphenomandibular ligament
• C. Temporomandibular ligament
• D. Stylomandibular ligament

Answer: (D)

Ernest syndrome is linked to calcification or ossification of the stylomandibular ligament. This ligament runs from the styloid process to the angle of the mandible and normally helps limit excessive jaw protrusion. When it becomes ossified, it forms a rigid band that can irritate nearby structures and restrict mandibular movement, producing pain and limited opening or protrusion that characterize the syndrome. Because the condition specifically involves the stylomandibular ligament, that ligament is the one associated with Ernest syndrome. Other ligaments—stylohyoid, sphenomandibular, or the temporomandibular ligament—are associated with different conditions and don’t define Ernest syndrome.
