Anthropometric Parameters of Nasomaxillary Complex in 2, 4, 6, and 12-Month-Old Children as a Reference for Cleft Lip and Palate Reconstructive Surgery

ABSTRACT The purpose of this study was to analyze the morphology of the nasomaxillary complex of Iranian healthy infants of 2, 4, 6, and 12-month-old.In this cross-sectional study, 232 healthy Fars infants of 2, 4, 6, and 12-month-old referred to Mashhad health centers were evaluated. Photographic images were taken from the infants' frontal view at rest position. Anthropometric landmarks including width of the mouth, nose, columella, width and height of the philtrum, and height of the upper lip were measured by Photoshop software.The authors did not find any considerable differences in nasolabial morphology of Fars children between boys and girls, except for columellar width and the width of superior philtrum at all intervals. The mean columellar width decreased with increasing age in both sexes. The width of the lower philtrum decreased from 2 to 4 months in both sexes, but increased from 4 to 6 months. In girls, the mean height of the right and left philtrum and height of the upper lip increased by increasing age from 2 to 4 months. But it consistently reduced from 4 months to 6 and 12-month-old. In boys, the mean height of the right and left philtrum and height of the upper lip decreased from 2 to 4 months. It showed a mild increase from 4 to 6 months, and a relatively large reduction from 6 to 12 months.This study provides useful information for reconstructive surgeries of the nasolabial region in the population studied.
