Philtrum length and intercommissural distance in newborn infants
Journal of Medical Genetics
|April 1, 1983
Summary
This study establishes standard measurements for newborn infant philtrum length and mouth width. These findings provide crucial reference values for assessing infant development and identifying potential growth abnormalities.
Area of Science:
- Neonatal Medicine
- Pediatric Anatomy
- Developmental Biology
Background:
- Accurate anthropometric standards are essential for neonatal assessment.
- Establishing normative data for facial features aids in early detection of developmental variations.
Purpose of the Study:
- To define standard values for philtrum length and mouth width in newborn infants.
- To provide reference data for clinical evaluation of neonatal facial development.
Main Methods:
- Examined 198 term and preterm infants (27-41 gestational weeks).
- Determined gestational age chronologically and clinically.
- Measured philtrum length and mouth width (oral intercommissural distance) using standardized techniques by two observers.
Main Results:
- Presented normal values for philtrum length and mouth width.
- Data plotted as mean +/- 2 standard deviations for each gestational week against gestational age.
- Established normative ranges for these facial parameters in neonates.
Conclusions:
- Provided reliable reference standards for neonatal philtrum length and mouth width.
- These standards can assist clinicians in evaluating infant growth and development.
- Facilitates identification of infants requiring further assessment for potential anomalies.
