Bilateral gluteal thigh flaps for closure of large defects in the lumbosacral region and perineal region.
Large defects in the lumbosacral and perineal regions were reconstructed with bilateral gluteal thigh flaps. These two patients demonstrate the versatility of the flap, which also was used as a sensory flap in one patient.

Dye laser treatment of port-wine stains.
The author treated 456 cases of port-wine stains using a tunable dye laser (577-nm wavelength, 1-microsecond pulse, 2-3-mm diameter spot), and followed up 22 cases for a year or more after the initial treatment. The treatment was regarded as effective in 80.5% of the abnormal lesions. The results were influenced by location: good results were achieved in the neck region and face, but results in the extremities were poor. The dye laser can achieve selective injury to abnormal vessels of port-wine stains while inflicting less damage to the overlying dermis than the argon laser. Therefore, dye laser treatment for port-wine stains is more effective than argon laser treatment.

A contrivance for monitoring skin flaps with a Doppler flowmeter.
A monitoring procedure using a Doppler flowmeter for assessment of patency after microvascular surgery is reported. Thirty-two free flaps were monitored using this procedure. There were three problematic cases in which flap circulation was not evaluated by the Doppler flowmeter. One involved the existence of another artery beneath the pedicle. The second was one of distal necrosis of the flap caused by impairment of peripheral blood circulation, in spite of patency of the pedicle. The third case involved venous occlusion of the pedicle, that was clinically detected by evaluating flap color, and the flap was salvaged. Checking beneath the pedicle prior to anastomosis was instituted after the first case cited, and there has not been a similar complication. The procedure has been proved to be useful in flap monitoring.

Surgical correction of Stahl's ear using the cartilage turnover and rotation method.
Various operative methods for the correction of Stahl's ear exist. We, however, have devised an alternative "turnover and rotation" procedure. In this procedure, the deformed cartilage itself is used in its original contour to form a new scaphoid fossa, thus simplifying the corrective procedure and establishing a reliable operative method in which reversion to the original state is thought to be highly unlikely.

The influence of congestion and ischemia on survival of an experimental vascular pedicle island flap.
We investigated the relationship between the survival rate of experimental rat pedicle island flaps and mild vascular insufficiency, using a flap designed to induce constant distant necrosis. To eliminate individual variation, the vasculature of each flap was evaluated by injecting dye prior to ligating either or both of the pedicle vessels. Seventy-five male Wistar rats divided into four groups were used. Six of the rats died, so 69 rats were evaluated. Statistically, the dye distance of each group was the same. In the control group of 29 rats, survival length was directly proportional to dye distance. Although the mean values of the survival length minus the dye distance of each flap (delta S.L.) in the venous inadequacy group were not different from those of the control group, there was significant difference between the mean values of the arterial insufficiency and the venous inadequacy plus arterial insufficiency groups and those of the control group. In the pedicle island flap, mild venous inadequacy was less responsible for necrosis when the arterial inflow was sufficient. However, when the arterial inflow was impaired, even mild venous inadequacy affected flap survival.

Our method of correcting cryptotia.
Our technique for the correction of cryptotia using both Z-plasty and the advancement flap is described. The main advantages are the simple design of the skin incision and the possibility of its application to cryptotia other than severe cartilage deformity and extreme lack of skin.
