PURPOSE: To evaluate the effect of intralesional injection of Pingyangmycin(PYM) for treatment of venous-venular malformation in the maxillofacial regions of children. METHODS: The medical records of 306 patients with venous-venular malformation in the maxillofacial regions between January 1997 and June 2005 were reviewed.

Pingyangmycin was injected into the center or in the vicinity of the venous-venular malformations, and repeated every 7 to 10 days. This cycle were repeated 3 to 5 times when necessary. RESULTS: Three hundred and six patients were followed up for 6 to 102 months.

The overall response rate was 100%, and the curative rate was 88.89%. CONCLUSION: This method is safe, simple and effective for venous-venular malformation in the maxillofacial regions of children.
