Zemlanskiy І. Anatomical variabiluty and morphometric charactiristions of sella turcica for three-dimentional computer modeling

The investigation object: anatomical variability of sella turcica. The investigation goal: investigation of individual anatomical variability of sella turcica for construction of computer model. Methods of research: morphologic, X-rays examination, computer modeling, statistical. The theoretical and practical importance of the received results: Detalization of typical manifestations of individual anatomical variabiluty and state peculiarities of the shape and morphometric parameters of sella turcica for its computer modeling with anatomical variabiluty of clinoid processes, carotid sulcus and sphenoid sinus was mode. It allowed to made the computer models of sella turcica with high amplitude of an individual variabiluty of the shape and sizes of the sphenoid sinus and clinoid processes, and also to connects the intrasinusal part of the internal carotid artery with the carotid sulcus. The scientific novelty of the investigation results. Detalization of typical manifestations of individual anatomical variabiluty and state peculiarities of the shape and morphometric parameters of sella turcica for its computer modeling with anatomical variabiluty of clinoid processes, carotid sulcus and sphenoid sinus. It is established, that the configuration of sella turcica and its components is more connected with the skull shape, and its morphometric characteristics – with sex. The computer model of sella turcica was an analogue to the bone preparate. It was revealed, that the building of the computer model of sella turcica in the system of 3Ds Max8 computer programm made with some conditions. It was necessary to measure the parameters of the plate coordinate points of the external surface of the sella turcica and the internal surface of the sphenoid sinus. The computer models of the external surface of the sella turcica and the internal surface of the sphenoid sinus was built independently from each other. Then we made the connection of these surfaces. The computer models of the sella turcica with the clinoid processes, connected intrasinusal part of the internal carotid artery with the carotid sulcus and also the different shapes of the sphenoid sinus may be used utillized in practice neurosurgery for surgical planned tactics. The degree of implementation: medicine, human anatomy.
