Были проанализированы данные мультисрезовой компьютерной томографии (МСКТ) 97 пациентов различных этнических типов с постпроцессинговой обработкой изображений в виде построения мультипланарных и 3D-реконструкций. Описаны характерные особенности конфигурации наружного носа и наиболее часто встречающиеся варианты грушевидных отверстий и носовых костей, в том числе их каудальную часть в месте соединения с хрящами. Анатомическая вариабельность данных структур, формирующих костную пирамиду и предопределяющих форму наружного носа, обусловливают цель (аугментация, редукция), тактику и выбор метода хирургического вмешательства у лиц, планирующих ринопластику.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study is to identify the anatomical variants of nasal bones structures in Caucasian (middle European and Balkano-Caucasian types) and Mongoloid patients. We performed a retrospective analysis of multi-slice computed tomography (MSCT) data of 97 patients with the image processing (multiplanar and 3D-volume rendering). Every kind of ethnic group has their proper specialties and descripted variants of pyriform apertures and nasal bones including its caudal part at the site its conjunction with nasal cartilages. The anatomic variability of these structures forming nasal shape determines the aim (augmentation, reduction) and methods of surgical approach in patients seeking rhinoplasty.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>наружный нос</kwd><kwd>носовые кости</kwd><kwd>грушевидное отверстие</kwd><kwd>ринопластика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Computed Tomography</kwd><kwd>External Nose</kwd><kwd>Nasal Bone</kwd><kwd>Pyriform Sinus</kwd><kwd>Rhinoplasty</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Итоги Всероссийской переписи населения 2010 года: Стат. сб. / Росстат.
