Abstract:
Objective To discuss the ultrasonographic feature and prognosis of the fetal dacryocystocele and its correlation.Methods The ultrasonographic feature of 51 patients diagnosed as dacryocystocele prenatally by sonography were retrospectively analyzed.All fetus were followed up to induced labor or 6 months after birth.The correlation between the size and the gestational age were analyzed by correlation analysis method and compared the fetal prognosis adopt U test.Results The incidence of dacryocystocele diagnosed prenatally by ultrasound was about 0.47‰.The diagnosis was established by the detection of a cystic lesion in relation to the medial and inferior aspects of the fetal orbit.Unilateral dacryocystoceles were more often found than bilateral,and left more than right.The maximum diameter range from 2.0 mm to 12.0 mm,average (5.9 ± 2.2)mm.There is no correlation between cyst size and gestational age.Prognosis of isolated nasolacrimal duct cyst is good.Conclusions The fetal dacryocystocele have typical ultrasonographic feature,Ultrasound is a rapid and reliable method which can be used for diagnosis of dacryocystocele prenatally and follow-up after birth.
