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 comparing 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.
