- Abstract
Background: To investigate the morphometric characteristics of the lacrimal sac fossa in Anatolian population using multidetector computed tomography (MDCT) images in surgical aspect. Materials and Methods: A total of 77 cranial MDCT scans were evaluated. The dimensions of the maxillary and the lacrimal bones forming the lacrimal sac fossa were measured in 3 axial planes (upper, middle, and lower planes). Results: The mean maximum thickness of the maxillary bone at the upper, middle and lower planes were: 3.58 mm, 4.27 mm, and 5.81 mm; the mean midpoint thickness at each plane were: 2.76 mm, 2.51 mm, and 1.48 mm; the mean lacrimal bone thickness at each plane were: 0.72 mm, 0.65 mm, and 0.66 mm; the mean distance between anterior and posterior lacrimal crests at each plane were: 5.96 mm, 8.1 mm, and 4.63 mm; the mean angle between the lacrimal bone and the sagittal plane in males and females at the middle plane were: 132.73° and 131.46°; the mean length of the lacrimal sac fossa in males and females were: 15.82 mm and 14.02 mm. Conclusions: In Anatolian population, bone thicknesses of the lacrimal sac fossa were higher in males, while the angle between the lacrimal bone and the sagittal plane was higher in females. This study indicated that osteotomies, which are the main target of dacryocystorhinostomy (DCR) interventions, can be easily performed in the Anatolian population.
