FIELD: medicine. SUBSTANCE: method involves comparing magnetic resonance tomograms and craniograms of one and the same patient taking into consideration spherical cranium vault shape during patient life time. Anterior border of corpus callosum is projected on the cranium vault 30 ± 2.8 mm forwards from the dorsum sellae vertical projection point and from mandibular articulation process in mesocephaly cases, 34 ± 4.0 mm in brachycephaly cases and 39 ± 3.7 mm in dolichocephaly cases. Posterior border of corpus callosum is projected on the cranium vault 52 ± 5.0 mm backwards from the dorsum sellae vertical projection point and from mandibular articulation process in mesocephaly cases, 45 ± 2.5 mm in brachycephaly cases and 49 ± 5.2 mm in dolichocephaly cases. Thalamus and ventricle III middle point is projected on the cranium vault 22 ± 3.1 mm backwards from the dorsum sellae vertical projection point and from mandibular articulation process in mesocephaly cases, 17 ± 2.0 mm in brachycephaly cases and 20 ± 2.8 mm in dolichocephaly cases. Pineal body is projected on the cranium vault 44 ± 5.1 mm backwards from the dorsum sellae vertical projection point and from mandibular articulation process in mesocephaly cases, 36 ± 3.3 mm in brachycephaly cases and 41 ± 4.2 mm in dolichocephaly cases. Bregm point projection, foramen interventriculare projection, transparent partition middle point and vault middle point projection are deviated for 2-5 mm backwards from the dorsum sellae vertical axis and from mandibular articulation process. Corpus callosum is projected in frontal plane on the cranium vault as 29-33 mm wide truncated cone in the anterior part, 34-38 mm wide at the level of foramen interventriculare and 44-47 mm wide at the level of pineal body. EFFECT: enhanced effectiveness in building projections of hardly accessible neoplasm formations during patient life time to enable development of surgical access to the formations to be of high accuracy. 2 dwg, 2 tbl
