Lumbosacral defects on 20 patients were covered with a perforator-based flap. Cutaneous perforators derived from the 9th and 10th intercostal arteries, the 4th lumbar artery, and multiple gluteal perforators that penetrate the gluteus maximus muscle were used as vascular pedicles. Minor complications occurred in five cases. Using this method, minimal morbidity of the donor site is expected because the gluteus maximus need not be sacrificed. Accordingly, perforator-based flaps are especially indicated for ambulatory patients, but for paraplegic patients as well. Even in the event of recurrence, another perforator-based or musculocutaneous flap can be elevated from the ipsilateral side because of the presence of multiple perforators in the lumbosacral and gluteal regions.

Between June 1989 and December 1996, the flashlamp pumped pulsed dye laser was used to treat port wine stains (PWS) in 644 patients, age range 3 months-93 years (mean 21). The efficacy of the treatment was assessed after more than one year of follow-up. Each factor that might affect the efficacy was then evaluated statistically. Broad lesions required more laser treatments than narrow lesions and clearing tended to start from the periphery of the lesion, indicating the three-dimensional depth of the broader PWS. Patients who had been given previous treatments such as argon laser required about two more laser treatments than those who had not, but there were no clear differences in the efficacy of dye laser treatment between the two groups.
