[Cutaneous retraction. Data from liposuction and other clinical procedures]

Area of Science:

• Plastic Surgery
• Dermatology
• Biomedical Engineering

Context:

• Skin expander techniques leverage skin's stretching capacity.
• Skin retractability is crucial for plastic surgeons.
• Suction lipectomy offers a method to study skin retractability without resection.

Purpose:

• To determine factors influencing skin retraction post-liposuction.
• To compare pre- and post-operative skin conditions in liposuction patients.
• To analyze the impact of treatment site on skin elasticity.

Summary:

• A study of 392 body and 108 cervicofacial liposuction cases identified age and fat volume affecting healing time.
• Treatment site significantly impacts skin's postoperative retractability.
• Neck and cheeks exhibit superior skin elasticity, defining an optimal 'golden triangle' for liposuction.

Impact:

• Findings suggest significant variations in skin elasticity across different body areas.
• Highlights the neck and cheeks as having optimal skin retractability.
• Data provides insights for other clinical observations on skin plasticity.
