Resection of Basal Cell Carcinoma and Lower Eyelid Reconstruction Surgery

Basal cell carcinoma is the most common cancer of the orbital area. It is 25 times more common in the eyelid than other malignant tumors, and it occurs mostly in the lower jaw. People who are more than middle-aged who are often exposed to the sun, aged 50 to 60 years, have slightly more men than women. Generally only local invasive growth occurs, and metastasis rarely occurs. However, improper treatment or no treatment, especially near the ankle tumor will invade the eyeball and lacrimal system, and even invade the sinus and the brain, can cause death. Treatment of diseases: basal cell carcinoma of the orbital basal cell carcinoma, preoperative preparation 1. Regular blood pressure, electrocardiogram, liver and kidney function, blood, urine, stool routine and platelet are normal. 2. Take a facial frontal image (one color and one black and white) centering on the left lower basal cell carcinoma. Surgical procedure 1. Under normal anesthesia, 5mm from the normal skin of the tumor edge, draw a skin incision around the tumor. 2, first from the upper eyelid and ankle skin line incision, under the normal humerus periosteum peeling, bypassing the external iliac crest to the lower iliac crest line, under the periosteum of the maxilla, peeling directly to the internal iliac crest (due to the sacral base Cellular cancer is very deep, so it is also peeled under the periosteum to ensure that the surgery does not touch the tumor). 3. When part of the periosteum and part of the fat in the external iliac crest are suspected to be invaded, the suspicious part of the iliac crest can be removed from the normal tissue. The inner and outer periosteum of the external iliac crest, part of the intraorbital fat, and the entire lower iliac crest include the conjunctiva of the iliac crest. Partial maxilla and part of the periosteum of the tibia were completely removed. 4, the external malleolus and the external iliac crest were sutured by supplementary incision, and the wound surface was completely closed. However, the entire chin and part of the buccal tissue were completely deficient, and the infraorbital bone was completely exposed. 5. Take a 2cm long 4, 5cm flap from the center of the forehead and transfer it to the chin and cheek defect surface. The upper edge of the flap is sutured with the residual bulbar conjunctiva and fascial cyst nodules. The lower edge of the flap and the cheek The wound edge is sutured. 6, the forehead for the flap area of the wound edge sneak separation and direct suture.
