Abstract

Measurement of 1298 Korean Children in Seoul (male 661; female 637) resulted in normal standard data for ear length and width by their age and sex. 1) Ear length and width were as follows respectively : 36.0¡¾2.5mm 21.5¡¾2.5mm in male neonate, 56.3¡¾3.1mm 30.6¡¾3.2mm at 6yr boy, 63.2¡¾3.5mm 33.4¡¾3.2mm in 14 yr adolescent male, 35.5¡¾2.0mm 21.2¡¾2.1mm in female neonate, 54.6¡¾3.1mm 28.7¡¾2.4mm in 6 yr girl, and 61.3¡¾4.1mm 31.8¡¾2.7mm un 14 yr adolescent female. 2) Ear grows rapidly during infancy, but thereafter grows slow and steady. 3) Size difference between left and right ear was statistically insignificant in bothsexes on the whole. 4) Male ear was significantly larger than female in all age groups, except in neonate and preschool age. 5) In comparison with American children, Korean ear length was slightly large by 2 mm in all age groups except neonate. 6) According to above Korean standard for size, we can objectively evaluate patients with abnormal ear size.
