[The efficacy of treatment of oral and maxillofacial venous malformations by pingyangmycin injection with different concentrations].

Purpose: To evaluate the clinical effect of using different concentrations of pingyangmycin to treat venous malformations in oral and maxillofacial region.
Methods: One hundred and ninety-four patients with venous malformations in oral and maxillofacial region were included and treated by pingyangmycin injection with different concentrations. For superficial cutaneous venous malformations, the concentration of pingyangmycin was 8mg/mL while 8mg/5mL for venous malformations limited to oral mucosa or submucosa.
Results: The efficient of cutaneous venous malformations was 94.9%,while 100% for oral mucosal and submucosa.
Conclusions: Using different concentrations of pingyangmycin for venous malformations in different sites can get good results and reduce unnecessary complications.
