A study of the os goniale in man.
The anterior process of the malleus of the middle ear develops irrespective of Meckel's cartilage through an intramembranous ossification center that appears in the human embryo of 26.5 mm crown-rump length at a caudomedial position in relation to Meckel's cartilage. The malleus has a double origin: the anterior process originates from the os goniale through intramembranous ossification, and the rest from Meckel's cartilage, through endochondral ossification.
