| 1. Objective(1) To give a systemic and comprehensive anatomic study to the periorbital fat pad, to differentiate the anatomic concept of each fat pad of the periorbital, to fill in the gaps in this systemic study and application and to avoid any anatomic concept confusion that exists in some part fat pad of the periorbital fat pad.(2) To study the relationship between the periorbital aging wrinkles and the distribution characteristic of the periorbital subcutaneous fat, to investigate the function of the periorbital subcutaneous fat in the development of the periorbital aging wrinkles. In the light of the anatomic mechanisms of the periorbital aging wrinkles, to investigate cosmetic and plastic methods that were aimed at the periorbital aging wrinkles, and to provide complete train of thought to cosmetic and plastic repairing of the periorbital aging wrinkles.(3) To investigate anatomic base and operation main point of the design of the brow subcutaneous fat flap and brow fat pad flap, to investigate the new clinic application value of the brow subcutaneous fat and brow fat pad, to provide an operation method of fat tissue transferring with blood supply to repair the sunken and/or multiply folded upper eyelid, too wide double eyelid deformity and to dissolve the difficult problem of the high absorption rate in free fat grafts for repairing the upper eyelid deformity.(4) To investigate anatomic base of the periorbital aesthetic deformity and the cosmetic and plastic methods for repairing the deformity. The major periorbital aesthetic deformity is the lateral upper eyelid fullness and heaviness, the sunken upper eyelid deformity, the bags of the lower eyelids and the sunken lower eyelid.(5) There still exist different views in dealing with the orbital fat pad during the lower eyelid blepharoplasty, we presented our views combine with our clinic practice.2. Materials and methods(1) Basic anatomic part(1)30 sides of 15 antiseptic adult specimens were studied, among the selected specimens, the age range was 20-60years.There were ten males and 5 females.(2)To dissect the subcutaneous per orbital area, peribrow area, the upper eyelid area, the lower eyelid area and the malar area layer by layer from surface to deep, To observe the distribution characteristic of the subcutaneous fat of each area of the periorbital by naked eye, to observe the relationship between the distribution characteristic of the subcutaneous fat of each area of the per orbital and the change of the periorbital aging, to observe the location, bound, neighborhood and blood vessel construction of the subcutaneous brow fat, the brow fat pad, The retro-orbicularis oculi fat pad and the suborbicularis oculi fat pad; to observe the scope of the retro-orbicularis oculi fat pad and the relationship between the brow fat fad and between the orbital fat pad; to observe the relationship between the suborbicularis oculi fat pad and the orbital fat pad; to measure the dimension and thickness of each fat pad; to mark theimportant blood vessel and nerve and to record the results by taking a photograph.(3)To design and develop the brow fat pad flap, to measure the dimension of the flap, the location of the pedicle, the main neighborhood, and the covering scope of the eye after the flap be transferred.(2) Clinic part(1)To observe the morphological appearance of periorbital aging wrinkles in clinic and to record the results by taking a photograph, and to use different methods of rhytidectomy for periorbital rejuvenation, for example: Treatment of wrinkles with Botox. treatment of wrinkles with autologous fat injection, treatment of wrinkles with hydrophilic polyacylamide gel injection, orbital and forehead facelift and blepharoplasty.(2) There were ten cases that accepted browplasty and ten cases that accepted foread-brow lift operation. During browpalsty operation we divided the orbicular oculi muscle and observed the exist of the brow fat pad.; and during the foread- brow lift operation through coronal incision w...
