In the repair of unilateral complete cleft lip, the most popular method is the rotation-advancement by Millard. Despite advantages of Millard repair, a few pitfalls exist. Above all, some of the scars, at the height of the cleft side philtral ridge, cross the Langer's line. Further, in the repair of complete cleft lip, small triangular lateral lip flap is often added in the base of an advancement flap to level the Cupid's bow. Moreover, preservation of the advancement flap has some negative effects on a primary nasal repair. As a result, the shape of philtrum is somewhat unnatural. Therefore, I applied the extended Mohler repair in the six cases of complete wide cleft lip to get a more esthetic scar. As a result, more natural, straight philtral ridge was obtained, without adding small triangular flap in the base of the advancement flap.

The purpose of this study was to investigate the maximal elongation rate and area expansion ratio of human skin in various postures. Five males and five females (male: $23{\pm}2yr$ in age, $177.9{\pm}4.8cm$ in height, $76.7{\pm}8.8kg$ in body weight, $24.2{\pm}2.5$ in BMI, $16.2{\pm}3.4%$ in body fat; female: $22{\pm}1yr$, $163.2{\pm}3.6cm$, $51.4{\pm}2.7kg$, $19.3{\pm}1.6$, $27.4{\pm}6.7%BF$) participated in this study. Measurements were conducted using a pen and tape on the elbow, knee, wrist, shoulder, and neck. Subjects held postures so that each joint of the body regions was bent at its maximal level. The results were as follows: 1) The maximal elongation rate of skin showed a significant difference among the regions: $16.6{\pm}3.4%$ for the wrist, $22.4{\pm}5.5%$ for the neck (back), $37.6{\pm}11.3%$ for the shoulder, $42.6{\pm}10.0%$ for the knee, and $43.9{\pm}4.0%$ for the elbow (p<0.05). 2) The maximal expansion rate of the body surface area had the greatest values on the elbow ($93.7{\pm}6.4%$) and knee ($74.8{\pm}10.8%$). 3) No significant difference was found between males and females. In summary, maximal values of skin elongation and expansion rates in vivo were greater than in vitro values known from previous reports. These results can be applied to develop electronic fibers or textiles for wearable tight fit work clothing as well as fitness wear.
