A Detailed Anatomic Study Based on the Mechanical Conduction Mechanism of Upper Eyelid to Facilitate Blepharoplasty and Repair of Complications

The levator palpebrae superioris-Müller's muscle complex serves as the primary dynamic structure for upper eyelid movement. It transmits force through the levator aponeurosis to the tarsal plate and skin, interacting with the detailed anatomic structures of the upper eyelid to complete the process of eye opening and closing. Through comprehensive analysis such as clinical observation, gross anatomy, and histological observation, the authors have clarified that the detailed anatomic structure of the upper eyelid and its mechanical balance are the prerequisite for successful upper eyelid plasty and provide a new theoretical basis for repairing various complications after blepharoplasty.
