This study analyzed the frequencies of the earlobe shapes in the Korean population. Data were collected on randomly selected 500 males and 500 females in Daegu Metropolitan City, with all participant ages being in their twenties. Obtuse angled earlobes accounted for 41.2% of the earlobes observed, while acute angled earlobes prevalence was calculated at 38.8% and right angled earlobe was 20.0% of the total (sexes combined). In men, the acute angled earlobe was the most frequent type (43.0%), while the obtuse angled earlobe was the most frequent type in females (45.2%). These differences were statistically significant (p = 0.015). Overall, attached type earlobe (61.2%) was more frequent than free type earlobe. The attached type earlobe was more common in both sex groups (57.0% in male and 65.4% in female),
