Определение нормативов ширины грушевидной апертуры в популяции по данным конусно-лучевой компьютерной томографии

Determination of the piriform aperture width standards in the population based on cone-beam computed tomography data

Currently, there are individual studies of the width of the piriform aperture (PA) in different populations, but these data are not tied to standards and do not take into account the age characteristics of the individual. Objective. To measure the width of the PA in the population in different age groups. Material and methods. The study involved 577 adults (≥18 years old) of the Central European type of the Caucasian race, divided into groups by gender (273 men and 304 women) and age (18—44, 45—59, 60—74 and over 75 years old), for whom the width of the PA was determined. Results. The value of the PA (in mm) width in men statistically significantly (p<0.05) exceeds the female values when com-paring both all subjects (24.13±0.20 in men and 22.67±0.19 in women) and separately among all age groups: 18—44 (23.46±0.34 and 22.05±0.43), 45—59 (24.13±0.42 and 22.56±0.34), 60—74 (24.15±0.41 and 22.64±0.31) and over 75 years old (24.87±0.40 and 23.43±0.40). Conclusions. The results can be used as standards for the width of the piriform aperture of the Central European type of the Caucasian race. © 2025, Media Sphera Publishing Group. All rights reserved.
