Tear Trough Deformity Correction With Autologous Fat Grafting Evidenced by Linear Gray Scale Analysis

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Ophthalmology

Background:

• Linear gray scale (LGS) analysis offers objective evaluation for facial aesthetics.
• Tear trough deformities impact facial appearance and are commonly addressed with aesthetic procedures.

Purpose of the Study:

• To evaluate the efficacy and patient satisfaction of autologous fat grafting for tear trough rejuvenation.
• To assess the correlation between patient-reported outcomes, clinical grading (Barton scale), and objective LGS analysis.

Main Methods:

• Retrospective study of 79 patients undergoing fat grafting for tear trough correction (2020-2024).
• Fat was injected using a retrograde linear threading technique.
• Aesthetic outcomes assessed via patient satisfaction surveys, Barton grading, and LGS analysis of pre/postoperative photos.

Main Results:

• Autologous fat grafting led to significant aesthetic improvement in tear troughs.
• High patient satisfaction reported (73.7% very satisfied or satisfied).
• Significant reduction in Barton grades and LGS scores (medial and central orbital regions) observed post-procedure; strong correlation between LGS and Barton grades.

Conclusions:

• Autologous fat grafting is a safe and effective method for tear trough rejuvenation.
• LGS analysis provides a standardized, objective, and quantitative tool for assessing aesthetic outcomes.
• LGS analysis results strongly correlate with clinical assessments like the Barton grading system.
