Abstract
Two-hundred and fifty-seven patients (136 adults and 121 children) with port-wine stains of the head and neck were treated with the flashlamp-pumped pulsed dye laser. The head and neck was subdivided into 8 anatomical regions (forehead/temple, periorbital, medial cheek, nose, upper cutaneous lip, lateral cheek, chin and neck) which were independently evaluated for response. Response to treatment was found to be associated with the anatomical location of the lesion; in both adults and children the mid-facial region (medial cheek, nose and upper cutaneous lip) responded less favorably to treatment than the other regions of the head and neck (periorbital, forehead/temple, lateral cheek, neck and chin). In adults and children, mean percent lesional lightening of the mid-facial regions was 70.7% compared to 82.3% of the other regions of the head and neck with an estimated difference of 11.6% (95% confidence interval: 8.7% - 14.6%). The mean number of treatments for adults was 3.7, while this number in children was 3.9. All side effects were transient, and included cutaneous depressions, hypopigmentation and hyperpigmentation.
