Application of Intratissue Laser Ablation in Facial Morphological Modification

Area of Science:

• Plastic Surgery
• Dermatology
• Biomedical Engineering

Background:

• Maxillofacial soft tissue concerns, including fat accumulation, aging-related sagging, asymmetry, and hyperplasia, impact facial aesthetics.
• Traditional surgical interventions may carry risks and longer recovery times.

Purpose of the Study:

• To retrospectively analyze the therapeutic efficacy of laser ablation for various maxillofacial soft tissue conditions.
• To evaluate patient outcomes, including aesthetic improvements and satisfaction levels, following laser ablation treatment.

Main Methods:

• A retrospective analysis of 97 patients undergoing laser ablation for facial fat accumulation, aging, asymmetry, and hyperplasia.
• Specific laser parameters were utilized for lipolysis (8 W, 90-120 J/cm²) and hyperplastic tissue ablation (9-10 W, 150-200 J/cm²).
• Evaluation included measurements of subcutaneous thickness, facial morphology assessment, and patient self-evaluation and satisfaction.

Main Results:

• Laser ablation demonstrated significant reduction in subcutaneous thickness and skin tightening, leading to a younger appearance.
• Facial morphology improved, with corrected or improved asymmetry and reduced hyperplasia.
• High patient satisfaction was reported, with swelling as the primary complication.

Conclusions:

• Laser ablation is an effective and safe first-line treatment for maxillofacial soft tissue laxity and thickening.
• The procedure offers low risk, minimal complications, and a rapid recovery period.
• It provides significant aesthetic benefits, enhancing facial contours and rejuvenation.
