Concept of triangular, trapezoidal, and rectangular debulking of eyelid tissues: Application in Asian blepharoplasty

There has been continued refinement and understanding in the concepts of Asian blepharoplasty. Among Asians, aesthetic upper eyelid surgery to convert a creaseless upper eyelid (popularly referred to as 'single eyelid') to one with a crease ('double eyelid') is the most frequently performed cosmetic surgery in Asia and among Asians living in the Western hemisphere. I have discussed my understanding of the concept of this surgery, utilizing a tarsal height-based external incision method plus asymmetrical debulking of the preaponeurotic tissues, including some fat, septum orbitale, pretarsal and preseptal orbicularis oculi muscles, and preseptal skin.
