[Morphometric characteristics and correlation interdependence of the lacrimal sac fossa and nasolacrimal canal in cerebral and facial parts of the skull of various shape].

Morphometric characteristics of lacrimal sac fossa (LSF) and nasolacrimal canal (NLC) were studied in 105 macerated skulls of humans of mature age. Extreme shape variants were detected for LSF and NLC inferior foramen. The peculiarities of topographic-anatomical relations of NLC with the neighboring structures of nasal cavity were established. Morphometric characteristics of LSF and NLC were found to be largely determined by the shapes of facial part of the skull, nasal cavity and orbit, and to a lesser extent by the shape of cerebral part of the skull. Some variants of LSF and NLC topographic-anatomical localization were found to exist that could predispose to spreading of an inflammatory process from the adjoining areas. Correlation analysis of morphogenetic relations of LSF and NLC has demonstrated significant dependence of only some dimensions in each of the skull shape variants.
