RESUMO
BACKGROUND: Capillary haemangioma is the most common orbital and eyelid tumour of childhood, with a prevalence ranging from 1 to 3%. Periorbital haemangiomas can cause amblyopia secondary to anisometropia, induced astigmatism, strabismus or occlusion of the visual axis. Oral and intralesional steroids are considered to be the most accepted form of primary treatment. The authors have been performing early surgery as definitive treatment in selected lesions and believe it has an important role. METHODS: A retrospective chart review of 17 infants (2-20 months old) seen between 1996 and 2002 was carried out. Indications for surgery in the present series were astigmatism, rapid growth, anisometropic amblyopia and obscuration of the visual axis. Thirteen were treated primarily with surgery and the other four were treated with other methods prior to considering surgery. Preoperative computed tomography scans were obtained when indicated. RESULTS: Fourteen lesions were completely excised; residual tissue was deliberately left in order to preserve vital structures in three cases. No major surgical complications were noted. One child with residual tissue after surgery, who had proliferation of the remaining tissue, developed anisometropic amblyopia and ptosis. One child had a mild ptosis postoperatively that resolved after 6 months. Follow up was for an average 11.1 months. CONCLUSIONS: Early surgical intervention should be considered in a multidisciplinary team approach as a primary treatment option with selected, isolated haemangiomas, without a significant cutaneous component. Surgery is a safe, effective treatment for selected lesions, provides a definitive early treatment, and prevents astigmatism and occlusion-related amblyopia.
