[Discussion of surgical laser manipulation of venous malformations in the parotid gland region].
OBJECTIVE
This study is carried to explore the surgical manipulation and complications of Nd:YAG laser coagulation for venous malformations in parotid gland region.


METHODS
The study included 84 cases of venous malformations in the parotid gland region, who underwent laser therapy after surgical approach three years ago. The results were evaluated by CT or MRI. Postoperative facial nerve function and intraoperative bleeding were analyzed.


RESULTS
Five cases had temporary facial nerve paralysis, which recovered spontaneously two months postoperatively. One case developed permanent nerve paralysis, which accounted for 1.19% in this group. The mean amount of blood loss was 200 ml. Four cases received blood transfusion.


CONCLUSIONS
Careful surgical dissection and correct laser irradiation is the key to successful treatment, which could preserve facial nerve from injury and decrease bleeding.
