CW-ND:YAG-LASER TREATMENT 0F CAPILLARY HAEMANGIOMAS OF THE LIDS
S. Schmitz, N. Pfeiffer, S. Pitz
Capillary haemangioma is the most frequent tumor of the periorbital region in childhood. It often grows progressively and shows spontaneous involution in the second year of life. Occlusion of the visual axis and tumor pressure on the globe can lead to amblyopia within only a few days. In these cases rapid treatment is necessary. Cryocoagulation and radiation can cause considerable side effects. The results of cw-Nd:YAG-laser treatment of the lids are reported.
Patients and Methods: 18 patients with capillary haemangioma of the lids (age: 2 months, median: 4 months, mean: 20 months) were treated. The tumors were cooled with ice, compressed and treated by cw-Nd:YAG-laser through a glass plate (bare fiber 0.6 mm, power settings 1-5 W, exposition time up to 6 sec) until the surface of the tumor bleached slightly. 15 patients were treated with steroid injections.
Results: Reduction of the tumor could be achieved in all cases. Redness of the skin could be reduced. Single vessels could be obliterated. In distinct cases amblyopia could be prevented. Initial swelling, superficial burns, scar formation and recurrence were possible side effects of the laser treatment. In one cases additional therapy with systemic interferon was necessary but was little successful.
Conclusion: cw-Nd:YAG-laser-treatment of capillary haemangiomas in early childhood is an effective method to decrease tumor size and prevention of amblyopia. Laser treatment seems to be of less side effects than radiation or cryocoagulation.
