Whether benign or malignant - the goal of every tumor operation is to completely remove the altered tissue while preserving eyelid function and the aesthetic eyelid aspect.
Many different types of tissue occur in the area of the eyelids and orbit, from which both benign and malignant tumors can arise. In clinical practice, "tumors" are also inflammatory eyelid changes that are accompanied by eyelid swelling. The actual eyelid tumors arise in the outer eyelid skin, in the eyelid glands and in the connective tissue. The most common benign tumors are the styes, the hailstones and the various eyelid warts. A special form are the pigmented tumors, the nevi, the melanoses and the melanomas.
More than 90 percent of malignant eyelid tumors are basaliomas. In the last two to three decades, they have been diagnosed with increasing frequency. One reason for this is that the post-war generation has increased exposure to sunlight. In some affected individuals, there is also a genetic predisposition.
The safest surgical option for larger eyelid basal cell carcinomas is two-stage surgery, in which the eyelid is not rebuilt until the tumor has been completely removed under histological control. All operations on the eyelids to remove tumors and to restore eyelid function after tumor removal have the goal of achieving an aesthetically and functionally optimal result. The surgical method used must depend on the location and extent of the tumor and, above all, on whether the change can be classified as benign or malignant.
