Abstract Objective: To assess the application value of three-dimensional ultrasonography in the diagnosis of congenital dacryocystocele. Methods: Ultrasonic findings of 18 fetuses with congenital dacryocystocele were retrospectively analyzed and compared with the findings after induction. All of the patients’ follow-up results were obtained from the Ophthalmology doctor or directly from the parents of children. Results: Congenital dacryocystocele ultrasonic image features: 2D ultrasound scanning showed well-defined anechoic fluid zone over the medial infraorbital area with no blood flow signal on CDFI. Three-dimensional ultrasonography could analyse the relationship between the lesions and surrounding tissues through multilayer surface by displaying the liquid zone through A-plane(sagittal section), B-plane(transverse section), C-plane(coronal section) at the same time. The bulging mass from the surface over the medial infraorbital area could be directly displayed by using three-dimensional surface imaging technology. The 18 fetuses were all diagnosed and confirmed with congenital dacryocystocele after birth. The cysts’ diameters were between 0.3~1.2 cm. There were no signs of eyeball compression or displacement. Conclusion: Three-dimensional ultrasonography can make comprehensive evaluation of congenital dacryocystocele, including the location, size, hemodynamic conditions, and relations with surrounding soft tissue and bony structures. When the longest diameter of congenital dacryocystocele was not less than 1.0 cm with no reduction by follow-up, low self-healing rate and poor prognosis would occur. Three-dimensional ultrasonography has great clinical value in diagnosis of congenital dacryocystocele.
