Observation of the Effect and Mechanism of Multi Tunnel Minimally Invasive Treatment for Xanthelasma Palpebrarum

"Multi level and multi tunnel puncture treatment steps~1. Disinfect the area within 1cm outside the edge of the eyelid xanthoma and lesion using iodine and cotton swabs three times;~2. Use a 1ml syringe to extract lidocaine for local anesthesia of the eyelid xanthoma lesion area;~3. Use a 1ml syringe to puncture the area between the epidermis and dermis layers, nipple layer, and reticular layer of the lesion, with the puncture endpoint at the edge of the lesion. Be careful not to penetrate the skin as much as possible, and when withdrawing the syringe, do not let the needle completely leave the puncture hole, leaving only one pinhole as much as possible; Within the same level, the distance between adjacent puncture tunnel ends is 1mm; Arrange the puncture tunnels staggered within adjacent levels;~4. Cover the injection site with gauze and maintain for 6-8 hours."

"(1) Disinfect the area within 1cm outside the edge of the eyelid xanthoma and lesion using iodine and cotton swabs three times; (2) Prepare heparin sodium and lidocaine in ratios of 1:1, and prepare 0.1ml of liquid per 1cm2 of lesion area; (3) Use a 1ml syringe to insert the needle from the edge of the lesion near the eyebrow, so that it will not cover the field of view with gauze after injection; (4) The injection depth is the gap between the epidermal layer and the dermis layer, forming an orange peel appearance after injection, and completely covering the lesion area; (5) Cover the injection site with gauze and maintain for 6-8 hours."
