Resumen

TAO, Hai et al. Ultrasonic 3D Reconstruction and Measurement of Lacrimal Sac in Normal Adult Chinese Population. Int. J. Morphol. [online]. 2016, vol.34, n.4, pp.1357-1361. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022016000400030.

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.
