A case of venous malformation in buccal region treated by direct injection sclerotherapy with dehydrated ethanol

Hemangioma and vascular malformations often occur in the oral and facial regions. We report the case of a 33-year-old man who had a venous malformation in buccal region and received direct injection sclerotherapy with dehydrated ethanol.Pretreatment MRA demonstrated blood flow from the facial and maxillary arteries through the lesion. Direct injection sclerotherapy with dehydrated ethanol was performed under general anesthesia. After the injection of dehydrated ethanol, the lesion shrank, and a good aesthetic outcome was obtained. There were no problematic side effects.The authors suggest that direct injection sclerotherapy with dehydrated ethanol is an easy, effective, and safe therapy for venous malformation.
