title: A study of the normal position of auricle in neonates.
abstract: The term "low-set ears" has been in common use for several decades to describe various malformation syndromes. But an accurate description of the normal position of the auricles is lacking in relevant literature. This study was designed to determine the normal position of auricles using bony landmarks that are less variable. The normal position of the auricle was determined in 1,000 neonates without any obvious congenital anomalies. A fixed bony point (point z) on the upper border of the posterior part of the zygomatic process of the temporal bone opposite the condyle of the mandible was selected. This point lies in front of the auricle and is easily palpable in neonates. The distance between point z and the upper and lower attachments of the auricle were measured as well as the distance between point z and the upper and lower poles of the auricle. The results were compared between the two sexes and between right and left sides. There was a wide variation in the distances measured in normal neonates. This highlights the importance of redefining the term "low-set ears."
