“…This explains why the majority cases are not diagnosed early in pregnancy, because the lesions are not present at the time of routine anatomic survey at 18 to 22 weeks of gestation. Indeed, the majority of reported cases of dacryocystocele were diagnosed at a gestational age of 30 to 32 weeks after a normal anatomy scan in the second trimester . In agreement with the literature, our cases series showed a mean gestational age at diagnosis of 30 (range, 23–35) weeks.…”

“…Looking for a non-invasive imaging method to accurately determine the location and size of lacrimal sac, as well as the anatomical relationships with the surrounding tissues, would provide the instructive meanings towards the diagnosis and treatment of lacrimal diseases. The ultrasonic 3D imaging (U3DI) is a newly emerging diagnostic technology, which could help the doctors to deepen the understanding of anatomic structures (Lembet et al, 2008;Bojikian et al, 2013;Byun et al, 2013). Prager et al, (2010) described the principles of U3DI, ultrasonic 3D digital beam forming technology, diversified 2D image collection, voxel model-3d image reconstruction, all greatly improved the resolution and quality of ultrasonic images, enrich the information that 2D ultrasound could not realize, and could understand more information of the internal structure from any cutting-angle section, meanwhile, it could provide a much more intuitive and repeatable 3D spatial form.…”

TAO, H.; LIU, X.; MEI, X.; HAN, C.; WANG, P. & BAI, F. Ultrasonic 3D reconstruction and measurement of lacrimal sac in normal adult Chinese population. Int. J. Morphol., 34(4):1357Morphol., 34(4): -1361Morphol., 34(4): , 2016. SUMMARY:To apply the ultrasonic 3D reconstruction method to measure the anatomic image data of lacrimal sac in the normal adult Chinese population, providing imaging anatomical basis for the clinical diagnosis and treatment of lacrimal duct diseases. 80 volunteers without lacrimal duct diseases were enrolled. The GE Voluson E8 ultrasonic diagnostic apparatus was used, with gynecological intracavitary probe (frequency: 5 ~ 12MHz) for the examination and measurement. Each datum was repeated three times for the average value. Among the 80 eyes, the lacrimal sacs of 74 eyes exhibited the clear imaging, with the imaging rate as 92.5 %. the vertical diameter of lacrimal sac cavity (LSC): 13.3±2.2 mm; anteroposterior diameter: 6.0±1.1 mm; trans diameter: 4.9±0.9 mm; the vertical distance from the sac cavity top to the skin surface: 6.3±0.12 mm, the vertical distance from the sac cavity bottom to the skin surface: 6.5±0.11 mm; the distance from the angular artery to the medial canthus: 7.8±0.05 mm; the vertical distance from the angular artery to the skin surface: 7.7±0.08 mm. The lacrimal sac and angular artery in the adults could be shown clearly in ultrasonic 3D reconstruction, the accumulated anatomical parameters could provide the instructive meanings towards the clinical diagnosis and treatment of lacrimal diseases.

“…Prenatal two‐ and three‐dimensional ultrasound examinations have also been used for the intrauterine diagnosis of this anomaly during the late second trimester, allowing appropriate postnatal management . Other imaging techniques such as computed axial tomography and magnetic resonance imaging are usually not necessary to confirm the diagnosis.…”

“…Prenatal two-and three-dimensional ultrasound examinations have also been used for the intrauterine diagnosis of this anomaly during the late second trimester, allowing appropriate postnatal management (4 spontaneously, after nasolacrimal duct probing, or may require surgical intervention. Because dacryocystoceles in newborns are almost invariably associated with nasolacrimal duct cysts, some authors recommend simultaneous probing and endoscopic cyst removal as the therapy of choice.…”
