[Anatomy and microstructure of the disco-malleolar ligament]

The disco-malleolar ligament was studied with the method of the anatomy and histology, and it's function was observed in the living people. It was found that the ligament takes its origin from the neck and anterior process of the malleus in middle ear and inserts into the capsule and meniscus of the temporomandibular joint. Part of the fibers was mixed with the spheno-mandibular ligament and attaches on the lingula of the mandible. The disco-malleolar ligament consists of collagenous fibers and elastic fibers. A peri-ligamentous space exists between the ligament and bone tissue. It was found the tympani membrana light cone area became smaller in opening position and larger in closing position. The existing peri-ligamentous space of the disco-malleolar ligament is a latent way between temporomandibular joint rear and tympanum.
