Simple procedure to evaluate mid-face sagging: A pilot study from Taiwan

Area of Science:

• Aesthetic medicine and dermatology
• Biomechanical analysis of facial aging

Background:

• Mid-face sagging is a significant indicator of facial aging.
• Objective and reproducible methods for assessing mid-face sagging are needed.
• Current assessment methods can be subjective and lack standardization.

Purpose of the Study:

• To introduce a simple, objective method for evaluating mid-face sagging.
• To correlate this measurement with aging factors like age and body mass index (BMI).
• To assess the potential utility of this method in evaluating anti-aging treatments.

Main Methods:

• Marking straight lines between the nasal alar and mandibular angle in supine and upright positions.
• Measuring the maximal distance between these two lines.
• Performing statistical analysis to correlate the measured distance with age and BMI.

Main Results:

• The maximal distance measurement demonstrated a positive correlation with age.
• The maximal distance measurement showed a positive correlation with body mass index (BMI).
• These correlations suggest the measurement reflects the degree of mid-face sagging.

Conclusions:

• This simple line-drawing method provides an objective assessment of mid-face sagging.
• The method's correlation with age and BMI validates its use in quantifying sagging.
• It holds potential for evaluating the efficacy of facial anti-aging interventions.
