[Oto-mandibular ligaments: disco-mallear and malleo-mandibular ligaments].
Phylogenesis, embryology and anatomy are emphasizing that two ligaments are found between the temporo-mandibular joint and the middle ear. These two oto-mandibular ligaments are named the disco-mallear ligament and the malleo-mandibular ligament. Originating from the first arch, these ligaments are not involved in the otologic manifestations of the temporo-mandibular joint syndrome. The disco-mallear ligament is a brake applied to the anterior excursion of the disc. When this disco-mallear ligament is stretched the disc can be displaced anteriorly breeding disc displacement, hypermobility and temporo-mandibular dislocation. The malleo-mandibular ligament is a remainder of the Meckel's cartilage: its role is not clear. When excessive forces are applying on the mandible, ossicles dislocation can be seen the forces being transmitted through it.
