"Subzone-Counting" Method in Asian Facial Liposuction: A Retrospective Study.

Area of Science:

• Plastic Surgery
• Cosmetic Procedures
• Facial Aesthetics

Background:

• Facial liposuction is a common procedure for facial contouring.
• Irregularities and asymmetry remain significant challenges in facial liposuction.
• The
• subzone-counting
• method was developed to address these complications.

Purpose of the Study:

• To introduce and evaluate the efficacy of the
• subzone-counting
• method in facial liposuction.
• To assess the method's impact on achieving facial symmetry and smooth contours.
• To determine the safety and patient satisfaction associated with this technique.

Main Methods:

• The facial liposuction area was divided into subzones using lines parallel to the earlobe-mouth corner line.
• Cannula paths within each subzone were kept parallel, utilizing consistent negative pressure.
• An objective index was created by counting aspiration in each subzone for real-time adjustments.

Main Results:

• The study included 32 Chinese patients who underwent facial liposuction using the
• subzone-counting
• method between January 2019 and January 2021.
• Follow-up ranged from 6 to 44 months, with 29 patients (90.6%) satisfied and 3 (9.4%) somewhat satisfied.
• No major complications were reported, and no patients were unsatisfied with the outcomes.

Conclusions:

• The
• subzone-counting
• method is a safe and effective technique for facial liposuction.
• This approach facilitates intraoperative judgment and adjustments, improving outcomes.
• The method enables easy achievement of contour smoothness and bilateral symmetry, reducing reliance on surgeon experience.
