Objective To explore the clinical value of outer auricle anomalies screening with swift, parallel translation and rotation of scanning method of ultrasound at the mid-end stage of pregnancy. Methods Retrospective analysis of 5533 cases of outer auricle anomalies screening with swift, parallel translation and rotation of scanning method of ultrasound was made, and compared with the results of induced abortion and postpartum. Sensitivity, specificity and diagnostic accuracy was calculated. Results There were 41 cases(0.74%) of anomalies in outer auricle: 8 in small ear, 6 cases including 1 case of skin tag were located at the right side , 1 at the left side; accessory ear was observed in 18 cases, 9 at right side and 4 at the left(2 cases associated with skin tag at ear), bi-lateral in 5 cases(1 case associated with right skin tag and facial cleft)；15 cases of external ear curvature,9 at right ,5 at left, 1 at bi-lateral sides. Bilateral images of outer auricles were detected in 99.6% of the study population; one side was not visualized in 14 cases and two sides in 8 cases. All the 8 cases of small ear(none missed), 29 cases of accessory ear(missed 11 cases), 5 cases of skin tag of ear( missed in 1 case) were confirmed after birth. 1 case of external ear curvature(the external ear was curled into a M shape with external auditory canal stenosis).The sensitivity and specificity was 71.05% and 99.75% on the screening of outer auricle with the swift, parallel translation and rotation of scanning method of ultrasound. Conclusions It is a quick, non-invasive and repeatable scanning method of swift, parallel translation and rotation of ultrasound, which can greatly increase the sensitivity and specificity of outer auricle before birth with high clinical value for popularization and application.
