| 目的 探讨快速平移偏转法在超声筛查中晚孕期胎儿外耳廓异常中的应用价值。
方法 回顾性分析超声快速平移偏转法筛查5533例胎儿外耳廓异常的情况，并与引产后或产后外耳廓的结果进行对照分析，统计这种超声扫查方法筛查外耳廓异常情况，包括敏感性、特异性等指标。
结果 5533例胎儿应用快速平移偏转法后，超声检出异常共计41例（0.74%）：小耳畸形8例，右侧6例（其中1例合并耳前皮赘），左侧1例，双侧1例；附耳18例，右侧9例，左侧4例（其中2例合并耳前皮赘），双侧5例（其中1例合并右侧耳前皮赘、右侧面裂）; 外耳廓卷曲15例，右侧9例，左侧5例，双侧1例。14例仅能显示一侧外耳廓，8例双侧外耳廓均未显示，胎儿双侧外耳廓显示率达99.6%。产后证实小耳畸形8例；附耳29例（漏诊11例）；耳前皮赘5例（漏诊1例）; 外耳廓卷曲1例（外耳廓卷曲成M形且合并外耳道
结论：快速平移偏转式超声扫描法简便、无创、可反复检查，能显著提高胎儿外耳廓畸形筛查的特异性、敏感性，具有临床广泛应用与推广价值。 |

| Abstract: |
| 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. |
