A Novel Method for Lower Blepharoplasty: Repositioning of the Orbital Septum Using Inverted T-Shaped Plication

Numerous techniques have been used for lower blepharoplasty. The techniques can be classified into four principles: excision of excess fat, septal reset, orbital fat repositioning, and reinforcement of the attenuated orbital septum.

We modified the conventional approach of septal reinforcement to utilize an inverted T-shaped plication with preservation of the orbital fat, repositioning the septum below the arcus marginalis to refine tear-trough deformity.

From April 2010 to September 2015, 93 individuals underwent bilateral lower blepharoplasty. Retrospective chart reviews were performed, and the results and complications during the follow-up period were recorded and photographed.

The patients comprised 76 women and 17 men. Thirteen, 33, and 47 patients exhibited mild, moderate, and severe fat herniation, respectively, accompanied by tear-trough deformity. A total of 70 and 23 patients underwent lower blepharoplasty via subciliary and transconjunctival approaches, respectively. We performed inverted T-shaped plication of the orbital septum in mild and moderate cases and X-shaped plication in severe cases, and in moderate and severe cases, we performed septal repositioning simultaneously. The mean follow-up period was 25 months. When immediate mild lid retraction or lid malposition was observed, it recovered without specific treatment within 1 to 2 weeks. No permanent lid malposition or ectropion was observed in any of the patients.

Septal plication with inverted T-shape or X-shape can minimize the downward forces that affect postoperative eyelid malposition and ectropion. Further, these procedures provide sufficiently strong reinforcement of the orbital septum to restore infraorbital fat herniation.
