OBJECTIVE: to morphometrically estimate normal variations in the sizes of lacrimal sacs on the basis of computed tomography findings to optimize the choice of endoscopic surgical intervention tactics for dacryocystitis.
MATERIAL AND METHODS: Preoperative orbital computed tomography data were comparatively morphometrically processed in two groups of patients with or without clinically verified dacryo- cystitis.
RESULTS: Data on the typical variants of the sizes of the lacrimal sac in health and in clinically manifested dacryocystitis were obtained and statistically processed. The advantages of using the design volume of the lacrimal sac over other measurements were shown. A method for the morphometry of lacrimal sacs was proposed on the strength of computed tomography data.
CONCLUSION: The obtained new refined data on the holotopy of the lacrimal sac in health and clinically verified dacryocystitis can simplify the choice of an approach to planning endonasal dacryocystorhinostomy.
