Female Abdominal Landmarks and Their Improvements Using Polydioxanone Thread Placement for Umbilicus Elevation.

Area of Science:

• Plastic Surgery
• Anatomy
• Aesthetics

Background:

• Abdominal aesthetics evaluation lacks standardized landmarks and measurement methods.
• Existing research shows no consensus on optimal landmarks for aesthetic assessment or surgical planning.

Purpose of the Study:

• To analyze abdominal aesthetic landmarks in female patients.
• To investigate landmark variations due to positional changes and polydioxanone (PDO)-assisted high-definition liposuction.

Main Methods:

• Analysis of female model photographs and actual patient data.
• Measurement of abdominal landmarks, focusing on the umbilicus as a key reference point.
• Recording landmark metric variations in standing vs. supine positions and pre/post-liposuction.

Main Results:

• The abdominal apex to mid-umbilicus (AU) versus mid-umbilicus to lower abdominal skin crease (UC) ratio was 1.626 in model photographs.
• Significant positional shifts (caudal) were observed in bony landmarks between standing and supine positions.
• Postoperative metrics improved after PDO-assisted liposuction, approaching ideal ratios, though individual deviations were noted.

Conclusions:

• Abdominal landmark metrics are position-dependent, making cross-position comparisons invalid.
• Achieving ideal AU/UC ratios (approx. 1.618) and other landmark metrics is crucial for satisfactory surgical results.
• Umbilicus repositioning offers flexibility in achieving desired aesthetic goals in surgical practice.
