title: [Clinical study on laser therapy of the venous malformations and hemangioma in oral and maxillofacial regions].
abstract: OBJECTIVE
  To try to find the best method of laser therapy for the management of venous malformation and hemangioma in oral and maxillofacial regions.
  
  
  METHODS
  From June, 1999 to July, 2002, 2 481 cases of venous malformations and hemangiomas were treated by several kinds lasers in our department. The lesions included port-wine stains, venous malformations, telangiectasia and hemangioma. The lasers used were continuous wave CO(2), Nd:YAG and Krypton lasers, pulsed dye laser and ultra-pulsed CO(2) lasers. The treatment modalities were direct irradiation, irradiation after surgical flap raising and photodynamic therapy.
  
  
  RESULTS
  Follow up between 2 - 5 years revealed the treatment results as follows: excellent is 79.24%, good is 14.31% and poor is 6.45%.
  
  
  CONCLUSIONS
  Laser therapy is one of the best method to treat venous malformations and hemangiomas. The key point is to apply different lasers properly.
