Relationship Between the Piriform Aperture and Interalar Nasal Widths in Adult Males

Abstract

The piriform aperture of 182 skulls of black and white males in the United States was measured and compared with soft tissue readings taken previously. Statistical analysis indicated that nose width prediction formulas currently utilized in facial reconstruction required modification. Two revised formulas are proposed to improve accuracy of reconstructions: an addition prediction formula for ease of use and a multiplication prediction formula for more precise results on those skulls outside of the mean range.
