[Laser-assisted blepharoplasty]

Blepharoplasty is one of the most frequently performed plastic cosmetic interventions. For this purpose the CO₂ laser is an instrument that can be used as a laser scalpel to cut as well as in its ablative function to remove skin irregularities, such as scars and tumors and also to treat changes of the skin due to aging. Fractionated laser irradiation reduces the duration of skin redness and the postoperative rehabilitation time after a resurfacing. The advantages of the CO₂ laser are a gentle intraoperative preparation and less postoperative swelling due to an additional cauterization of blood vessels. Disadvantages are an increased occurrence of wound dehiscence and the high cost of instrumentation. Before performing a blepharoplasty an exact analysis of changes of the eyelid and also the wishes of the patients are necessary to establish the most suitable surgical procedure and the correct dosage. In addition to skin and fat resection, depending on the original situation it is possible to tighten slack skin with a resurfacing, to shift the fat compartments, to change the position of the eyebrows, to correct a ptosis and also to modulate the tension of the lid. The frequency of complications can be reduced by good planning of the surgical intervention. In the case of occurrence of complications, suitable treatment strategies should be available.
