      Summary

      Background

      Medial epicanthoplasty is commonly used to enhance the aesthetic outcomes of double-eyelid operations in Asia. However, epicanthoplasty can cause problems such as scarring and excessive exposure of the lacrimal lakes.

      Objectives

      To resolve the problems associated with epicanthoplasty and to create more natural and long-lasting double-eyelid fold lines while minimizing incisions, we performed a 45-degree upward tension-releasing epicanthoplasty.

      Materials and Methods

      A total of 712 patients underwent 45-degree upward tension-releasing epicanthoplasty, with or without double eyelidplasty. A triangular skin flap was elevated at a 45-degree angle from the epicanthal fold. The surrounding area was dissected to eliminate the rigid connective tissue between the orbicularis muscle and the skin, which creates skin tension. The incisions were sutured, and a small incision toward the medial canthus was added to further decrease tension and create space for the triangular flap to be transposed.

      Results

      A total of 707 patients underwent 45-degree upward tension-releasing epicanthoplasty with the double-eyelid procedure, and 5 patients underwent 45-degree upward tension-releasing epicanthoplasty alone. No complications were observed for any patients, and 95% of patients were satisfied with this technique.

      Conclusions

      The 45-degree upward tension-releasing epicanthoplasty can release the tension in the epicanthal fold, minimize scarring, and control lacrimal lake exposure. In particular, this method was effective for creating an in-out double-fold line starting from the epicanthus and for maintaining the double-eyelid line, which can reduce unnecessary incisional double-eyelid surgery.
