The stylomandibular ligament is a specialized band of the cervical fascia. Although classed among the ligaments of the temporomandibular joint, it can only be considered as accessory to it.

Attachments and Course

This ligmaent extends from near the apex of the styloid process of the temporal bone to the angle and posterior border of the angle of the mandible, between the Masseter and Pterygoideus internus. It separates the parotid from the submandibular gland and medial pterygoid, and from its deep surface some fibers of the styloglossus take origin.


Along with the sphenomandibular ligament, the stylomandibular ligament is responsible for limiting mandibular movements (limits excessive opening).
