Meibomian adenocarcinoma excision eyelid reconstruction

The meibomian adenocarcinoma is a malignant tumor that originates in the sebaceous glands. Once the diagnosis is clear, it is best to extensive surgical resection, frozen section to monitor the resection margin, resection should include 5 ~ 6mm of normal tissue around the tumor, and some even more extensive surgical resection. The use of cryosection monitoring to control the resection margin does not guarantee radical cure, as multiple lesions are not interconnected and are characteristic of meibomian adenocarcinoma. Treatment of diseases: meibomian adenocarcinoma preoperative preparation Perform routine physical examinations, including testing of various blood indicators. Surgical procedure 1. Using methylene blue, iodine, 2mm line from the normal tissue of the edge of the cancer. The inverted tumor is marked with a knife edge on the conjunctival surface. 2. Wrap the cancer with several layers of gauze and cut the tumor with scissors along the line. 3. Frozen sections confirmed that the tumor resection margin was normal tissue without any tumor cells. 4. Separate the remaining skin, orbicularis muscle to the humerus, and pull down. 5. Separate the residual tarsal plate and the palpebral conjunctiva to the dome. 6. According to the size of the plaque defect, take the corresponding allogeneic sclera. 7. Stitch the scleral strip with the 4-0 silk thread and the ends of the residual jaw. 8. The upper edge of the scleral strip is sutured continuously with the lower edge of the stump. 9. The conjunctiva and the orbicularis tendon suture. 10. Cut the ash line and divide the chin into the front and back leaves. 11. The posterior iliac crest and the upper iliac crest (conjunctiva and allogeneic sclera) are sutured, and the internal and external iliac crests are not sewn for drainage. 12. The anterior humerus and the upper layer of the upper jaw (skin, orbicularis) are sutured, and the inner and outer corners are not sewn. 13. Trim the "cat's ear" formed by pulling the skin down, and the skin is sutured intermittently. 14. After the operation, the conjunctival sac was washed with 0.25% gentamicin saline, and the antibiotic ointment was coated with the conjunctival sac and bandaged with a single eye bandage.
