Epicanthoplasty with Epicanthal Dermatic Tension-Releasing Incision Based on Skin Projection of Inner Canthal Ligament

Epicanthoplasty is a reconstructive procedure that eliminates the deformity of the epicanthal fold and provides a more esthetic inner canthus. The epicanthal tension-releasing incision is a core technique of epicanthoplasty. However, which epicanthal dermatic tension-releasing incision most effectively provides epicanthal tension release remains unclear. We designed a novel dermatic tension-releasing incision based on the skin projection of the inner canthal ligament and compared it with the more conventional incision parallel to the lower inner canthal mucocutaneous junction (white line).
From December 2014 to March 2016, 30 patients were divided into two groups according to the type of dermatic tension-releasing incision. Each group comprised 15 patients and 30 eyes. In Group A, incision line a was performed (tension-releasing incision parallel to the lower inner canthal mucocutaneous junction, 4–5 mm away from the mucocutaneous junction). In Group B, incision line b was performed (tension-releasing incision pointed toward the lacrimal lake, along the skin projection of the inner canthal ligament). The defect angles of the two groups were photographed intraoperatively after tension release and analyzed postoperatively.
The defect angles in Group B were significantly larger than group A (P < 0.0001). All patients obtained an esthetically pleasing inner canthus without hypertrophic scarring or injury to the lacrimal apparatus during the 3- to 24-month follow-up period.
An epicanthal dermatic tension-releasing incision based on the skin projection of the inner canthal ligament is more effective and safer than an incision parallel to the lower inner canthal mucocutaneous junction.
