Objective: To investigate the correlation of healthy skin thickness and echogenicity with age, anatomic site and gender by high-frequency ultrasound.

Methods: A total of 82 Chinese children in our department were selected as subjects, whose healthy skin thickness and echogenicity was measured using high-frequency ultrasound (DermaLab Combo, Cortex, Denmark) to examine whether there was statistical difference in skin thickness among different ages, anatomic sites and genders.

Results: There was statistical difference in skin thickness and echogenicity among different anatomic sites and age groups (P<0.05); there was no statistical difference in skin thickness and echogenicity between different genders (t=0.49; P>0.05).

Conclusion: High-frequency ultrasound can accurately measure the healthy skin thickness and echogenicity in children. Skin thickness and skin echogenicity is correlated with anatomic site and age, but not correlated with gender.
