"Blepharoplasty is a commonly performed aesthetic surgery, but there is still no commonly used standard method for the correction of orbital fat bulging in lower blepharoplasty. We performed dual plane method by elevating skin flap and muscle flap separately, and then repositioned orbital fat with preserving orbital septum for correction of orbital fat bulging in lower blepharoplasty. Between July, 1998 and June, 2005, one hundred and fifty six patients underwent lower blepharoplasty by authors method. The results were satisfactory in all of the patients. Complications were six cases of hematoma and ten cases of visible scar in lateral canthal area. There was no skin flap necrosis, hyperpigmentation, skin irregularity or ectropion. In lower blepharoplasty for the sufficient excision of skin and operation of orbicularis oculi, we performed precise correction of skin and muscle independently by dual plane approach, by separate elevation of skin flap and muscle flap, and were able to reposition orbital fat easily and safely with preservation of orbital septum."
