Stereotopometry used in morphology for imaging three-dimentional organ structure is applied to study individual changeability and spatial relationships of laryngeal structures in adults depending on the type of constitution and form of the neck. Fifty preparations from male corpses with three types of constitution were studied. An original stereotopometer able to localize 106 points on external and internal laryngeal samples to each of three coordinate planes was introduced. The coordinates of certain points were pooled in variational series for characteristics of which the following parameters were determined: arithmetic middling (X), error in arithmetic middling (m), standard deviation (S), correlation coefficient (r). To characterize a constitution type and form of the neck, the following measures were used: length of the body, acromial diameter, chest perimeter, anterior length of the neck, cervical circumference. Morphometric data obtained were investigated with paired correlation analysis. The studies show a definite correlation between spatial relation of laryngeal structures and constitutional type and shape of the neck. This is essential in choice of reconstructive laryngoplasty regarding anthropometric data.
