Sphenomandibular ligament

Dr Craig Hacking et al.

The sphenomandibular ligament is one of the 2 extrinsic ligaments of the mandible. It descends from the spine of the sphenoid bone onto the medial surface of the mandibular ramus, attaching to the lingula. It is the primary passive support of the mandible, along with the muscles of mastication.

The other extrinsic ligament is the stylomandibular ligament.

Relations

It is pierced by the nerve to mylohyoid. The auriculotemporal nerve and inferior alveolar vessels pass between it and the neck of the mandible.
