Surgical treatment of hemangiomas and vascular malformations in functional areas.

Hemangiomas and vascular malformations (VM) in functional areas can be treated by a variety of methods. Because of the natural involution of hemangiomas, a non-agressive approach is recommended. Active therapy is necessary only in cases where a function is affected such as vision, respiration, hearing, and feeding. Psychological problems can be an indication for early excision, and psychological/cosmetic reasons in the presence of fibrofatty tissue residues when the hemangioma has been involuted for late excision. In contrast to hemangiomas, no involution is to be expected for VMs, so that therapy depends mainly on the occurrence of functional problems and/or serious complications. Surgical excision still has a place, however, the indications are limited.
