MORPHOMETRIC VARIATION OF ORBITAL AND CRIBRIFORM PLATES OF ETHMOID BONE IN ADULTS

Sex variation of linear parameters of ethmoid bone structures depending on visceral cranium structure are studied in this article. Latitudinal, altitudinal and longitudinal measurements of orbital and cribriform plates of ethmoid bone and their mean value were obtained by the computer craniometric method. The combination of the computer craniometric method and the computer program “Cranio” developed by us allowed using the method of three-dimensional topometry for getting data on space relations of these structures in nasal cavity. The parameter variation of ethmoid bone structures depending on visceral cranium structure was revealed. Sex and bilateral variation of linear parameters of studied structures were not found. The mean value of parameters with insignificant variation can be recommended for working out optimal surgical accesses in otorhinolaryngology. It is necessary to conduct the computer craniometry for initial definition of visceral cranium structure in the preoperative examination procedure of the patients with chronic rhinosinusitis.
