Nd-YAG laser treatment of venous malformations of the head and neck: an update.

Abstract

Malformations of the arterial and venous systems often are manifested in the head and neck. Low-flow venous malformations are generally benign lesions; however, complications, such as bleeding, obstruction, pain, or cosmetic deformities, may warrant surgical intervention. Treatment of these lesions can be challenging. Laser photocoagulation, particularly with the neodymium-yttrium aluminum garnet (Nd-YAG) laser, has been successful in the majority of patients, with minimal morbidity and good results. Thirty-two patients with low-flow venous malformations of the head and neck were treated with the Nd-YAG laser using low-power density and intermittent short exposures in a punctate nonoverlapping technique. When possible, two glass slides were used to compress the lesion. There was excellent regression with minimal damage to the surrounding tissue. No major complications or morbidity, postoperative pain, or mortality occurred. Lesions occurring in some areas of the head and neck would not have been amenable to standard surgical excision. Follow-up period has ranged from 1 to 8 years. Nd-YAG laser photocoagulation has proved safe and effective for treatment of low-flow vascular malformations of the head and neck.
