The orbital region includes the upper and lower lids, the inner and outer canthus, and the eyeball region. The eyelids are the first area to show skin aging, mainly due to skin laxity, herniation of orbital fat and atrophy of the orbicularis oculi muscle. Aging of the orbital region is the earliest part of the face to show signs of aging, especially in the upper eyelids, which can look old. The appearance of the cheek grooves (tear troughs) also gives the impression of a lack of energy and a haggard appearance. A full lower eyelid orbicularis oculi muscle gives a “silkworm” shape when smiling, enlarging the eyes and making them cute. Therefore, the main areas for orbital fat injection are the upper eyelid, the tear trough area and the lower eyelid margin area. I. Grid division The aesthetic subunits of the orbital region are: brow-lid area, lid-cheek area (tear trough area), nasolabial area (medial canthus area), lid plate area and lower eyelid margin area (oculodorsal area). Second, autologous fat transplantation (a) transplantation method The total amount of orbital fat filling is 2~10mL, average 3mL. sampling site: inner and outer thighs and lower abdomen. Sampling method: After local swelling anesthesia, a 20mL syringe was connected to a 1.5mm diameter liposuction needle to slowly extract fat under negative pressure. Fat purification: Using the static precipitation method, the fat tissue was washed repeatedly with cold saline at 4℃, the long needle was used to pick out the fibrous connective tissue, and then centrifuged at 1000r/min for 5min before use. Needle point selection: the upper eyelid part was at the inner edge of the lateral wall of the orbit, and the lower eyelid part was at the lateral canthus of the lower eyelid. 2% lidocaine, local infiltration anesthesia was used to anesthetize the affected area, and a 16-gauge needle was first used to puncture the entry point for injection, and then a 1mL syringe connected with an injection needle with a diameter of 1.0mm was used to insert a needle into the upper eyelid, the lower eyelid rim, and the lacrimal sulcus, and then after pumping back to the area, the needle was slowly withdrawn and injected uniformly into the affected area, and the levels of the injected area were the subcutaneous and the upper layer of periosteum; the injection was gently pressed after injection. The injection level is subcutaneous and upper layer of periosteum; after injection, gentle pressure is applied to shape the area. Erythromycin ophthalmic ointment was applied at the point of injection and covered by sterile band-aid; after the operation, the recipient area was iced intermittently for 72h, and oral antimicrobial drugs were taken for 3d, and the wound was kept away from water for 5d. (2) The key points of injection in orbital part (1) Compared with hyaluronic acid and other materials, granular fat transplantation has the advantages of homologous tissue, rich source and long-lasting effect. (2) The skin of the orbital area is thin and easy to bleed, so attention should be paid to the fine and gentle operation when injecting, and the injection should follow the principle of “less rather than more” to prevent the accumulation of fat locally and the formation of lumps and uneven appearance. (3) The injection level of the upper eyelid depression is in the subcutaneous tissue layer and orbital septum, the injection level of the lower eyelid oculus is in the subcutaneous, and the injection level of the tear trough is in the supraperiosteal layer and subcutaneous tissue layer. (4) Enhanced intraoperative compression for hemostasis and postoperative ice packs can effectively prevent adverse reactions such as bruising and hematoma. (5) Double lower lid margins close to the lower edge of the eyelashes make the eye table look more dynamic when both eyes smile. The long oval shape of the oculus gives the oculus the best aesthetics. When injecting, use a cotton swab against the eyelid margin to shape the eyelid while pushing the injection, and pay attention to preventing the formation of hypertrophy and bloating of the undesirable appearance by over-injection. (6) Eye injections should be skillful in anatomical structure, avoiding blood vessels, gentle, small amount, blunt needle injection, to prevent the occurrence of thrombus and other serious adverse consequences.
