THE FACIAL DISTRIBUTION OF PORT WINE STAINS ON PATIENTS PRESENTING FOR LASER TREATMENT

During a 2-year period, 232 patients with port wine stains presented for laser treatment. They were analyzed for the position of the port wine stain with respect to the right and left ophthalmic, maxillary, and mandibular divisions of cranial nerve V and the right and left cervical plexus. Fifty-one percent of the facial lesions were confined to either the right or left maxillary division, and 72% of the lesions were confined to just one of the eight nerve regions; 5.9% of the lesions occupied regions on both sides of the face, whereas 49.8% were confined to the right side and 44.3% to the left. In comparison with a group of 103 patients studied by Ohtsuka of Japan, there appeared to be significantly more patients in the maxillary division (p < 0.00001) and significantly fewer patients in the ophthalmic division and in the combination of ophthalmic and maxillary divisions (p < 0.00001).
