"The external ear is developed from six auricular hillocks arising from the first and second pharyngeal arches. The first pharyngeal arch gives rise to hillocks 1 to 3, and the second forms auricular hillocks 4 to 6; the antihelix, antitragus, and concha are derived from the latter 3."
"The external ear plays an important role in conducting sound into the external auditory canal; its unique shape helps facilitate this. A number of ear deformities exist, and detailed knowledge of ear anatomy is required in reconstructive surgery, not only to restore the aesthetic appearance of the ear but also to ensure functionality."
