Morphometric analysis of the upper lip in Koreans

Area of Science:

• Anatomy
• Anthropometry
• Facial Morphology

Background:

• The philtrum and upper red lip are key facial aesthetic and functional components.
• Understanding their detailed morphology is crucial for reconstructive surgery and anthropological studies.

Purpose of the Study:

• To quantify the dimensions of the philtrum and upper red lip in Korean young adults.
• To identify sex-based morphological differences and compare Korean dimensions with other ethnicities.

Main Methods:

• Measurement of 10 key dimensions of the philtrum and upper red lip in 251 healthy Korean adults.
• Calculation of various indices and classification of philtrum shape.
• Statistical analysis to determine significant differences between genders and ethnic groups.

Main Results:

• Significant differences in philtrum width, mouth width, and upper lip height were observed between males and females.
• A negative correlation was found between the philtral column length and upper red lip height.
• Distinct dimensional differences were noted between Korean and Caucasian populations.

Conclusions:

• The study establishes normative anthropometric data for the philtrum and upper red lip in Korean young adults.
• Identified gender and ethnic variations provide valuable data for facial analysis and surgical planning.
• Results can inform aesthetic and reconstructive procedures involving the upper lip.
