... of the auditory ossicles suggests that the malleus/incus is derived from the first branchial arch cartilage (Meckel's cartilage) and the stapes from the second branchial arch cartilage (Reichert's cartilage). An anomaly of the first branchial arch would therefore induce an anomaly of the malleus/incus, whereas...
