OBJECTIVES: Absence or congenital anomalies of the parotid glands are associated with significant long-term morbidity. To date there are no published data on ultrasonographic detection of these defects in early pregnancy. We set out to demonstrate and measure the fetal parotid and submandibular salivary glands at 14-16 weeks using transvaginal ultrasound imaging. METHODS: During a routine fetal anomaly detection scan in 30 consecutive patients, an attempt was made to examine the fetal parotid and submandibular glands. The fetal head was scanned in transverse sections just below the fetal ears, and the area of the parotid and submandibular glands was inspected. The examination time was not prolonged for the purpose of measuring the salivary glands. The fetal biparietal diameter and the femur length were also documented. RESULTS: The median gestational age was 15.4 (range, 14.4-16.5) weeks. In all 30 patients examined, at least one pair of parotid and submandibular glands was clearly visualized and measured. In seven patients the parotid and submandibular glands were visualized on both sides. The median length of the parotid gland was 7.5 (range, 5.5-11.5) mm and that of the submandibular gland was 5.4 (range, 3.7-8.5) mm. CONCLUSIONS: The fetal salivary glands can be demonstrated by transvaginal ultrasound imaging at 14-16 weeks of gestation. This is the first reported study presenting the normal values of salivary gland measurements, which may be important in detecting fetuses with congenital absence or other malformations of the glands.
