Abstract：Objective To investigate the value of color Doppler ultrasound(CDU)in the diagnosis and differen-tial diagnosis of congenital preauricular fistula(CPF).Methods Data from 117 patients with surgically confirmed CPF from February 2010 to February 2021 were retrospectively reviewed,including ultrasound descriptions,surgical notes and pathological results,which were used as the standard for comparison.Results CPF consisted of 2～4 branches in 32 cases,and CDU descriptions were consistent to surgical findings in 112 cases(95.7%)(r=0.429 P<0.01)and consistent to actual branch courses in 18 cases(56.3%)(r=0.071,P=0.279).CDU correctly revealed perichondrium invasion by CPF in 32 of the 46 cases(69.6%)(r=0.088,P=0.146).CDU accurately described the relationship with the temporal fas-cia in all cases(r=1.000,P<0.01),with peripheral arteries in 74.7%(62/83)of the cases(r=0.065,P=0.094),with veins in 65.4%(34/52)of the cases(r=0.066,P=0.183).Conclusion CDU can reliably demonstrate the main tract of CPF,the course of blind tubes and their relationship to the temporal fascia,but not that with peripheral blood vessels or perichon-drium.CDU bears important values in the diagnosis of this diseases and can help clinicians in treatment decision making and surgery planning.
