Objectives: Down syndrome is a genetic disorder that can be seen frequently in the community. These patients have
many anatomical malformations and comorbidities. They often require medical intervention and need a specialized
approach. In this study, we aimed to measure the auricle dimensions and evaluate the ear development of Down
syndrome patients, who can have various diseases related to the ear
Methods: A total of 19 groups were formed, consisting of all ages from the neonatal period to the age of 18 and
the adult group that consist 18 years and over. 20 patients in each group, a total of 380 patients participated in the
study. After all patients and / or their relatives were informed, measurements were taken from their right ears in
six dimensions. These measurements were planned as suprahelix to infralobule, helix to tragus, antihelix to tragus,
concha attachment point to tragus (conchal depth), suprahelix to mastoid and helix to mastoid at tragus level. After the
measurements were taken, all groups were divided into girls and boys and statistical analyzes were performed.
Results: It was observed that the height of the infralobule auricle from suprahelix reached adult age at 13 years of age
in boys and girls. The width of the auricle from the helix to the tragus reached adult age at the age of 5 in boys and girls.
The distance between antihelix to tragus reached the adult value at 1 year of age in boys and did not differ significantly
from the adult value in any age group in girls. It was observed that the conchal depth reached the adult value at the age
of 8 in both genders . The distance from the suprahelix to the mastoid reached the adult value at the age of 7 in boys
and girls and distance from the helix to mastoid at the tragal level reached the adult value at the age of 4 for boys and 5
for girls. Adult ear sizes were 59.83 mm and 56.25 mm for men and women, respectively.
Conclusion: The ears of individuals with Down syndrome are smaller than those of adults mentioned in the literature,
and the age of development is observed lately. These data are thought to be important in terms of decision and timing
of auricular surgery in patients with Down syndrome, and medical instruments such as hearing aids. Since the auricula
size can vary according to ethnic origin, gathering the data from different societies is valuable for the literature.
