Craniofacial and Velopharyngeal Dimensions in Infants 0-12 Months: Between- and Within-Group Differences Based on Age and Sex.

Purpose: The purpose of the present study is to (a) provide quantitative data on the growth of levator veli palatini (LVP), velopharyngeal (VP), and craniofacial dimensions in children under 12 months while controlling for corrected age and sex and (b) compare variability within age and sex groups.

Method: Magnetic resonance imaging scans of 75 infants between 0 and 12 months were measured and divided into four age groups. These data were obtained as part of a larger retrospective study.

Examining Craniofacial and Velopharyngeal Structures in Premature Infants: A Window Into the Womb.

Background: Very little is known about how the velopharynx and levator veli palatini muscle develop in utero. The purpose of this study was to describe craniofacial, velopharyngeal, and levator veli palatini dimensions in a group of infants born prematurely and imaged before 40 weeks gestation.

Methods: A retrospective, descriptive study design was utilized to examine the MRI scans of 6 infants less than 40 weeks' gestation.
