Clarifying the role of skin tension lines in dermatological surgery
Abstract
Skin tension lines are fundamental guidelines in surgical procedures for determining optimal incision placement to enhance healing and minimize visible scarring. This paper delves into the historical development and practical implications of Langer lines and relaxed skin tension lines. Utilization of relaxed skin tension lines enhances the precision of incisions and closures by considering facial muscle tension, an aspect not addressed by Langer cleavage lines. Relaxed skin tension lines more accurately reflect skin dynamics, underscoring the importance of patient positioning. Additionally, Cornelius Kraissl played a significant role in highlighting the alignment of scars with wrinkle lines. The interchangeable use of relaxed skin tension lines and Langer lines often leads to confusion within the field. Clarifying their distinct origins and criteria is crucial for the optimization of surgical outcomes.
