Abstract:

BACKGROUND

Because the “lateral limbs” resulting from conventional Z-plasty form a steep angle against the relaxation skin tension line (RSTL), they often develop hypertrophic change, whereas the “central limbs” become inconspicuous after being realigned parallel to the RSTL. OBJECTIVE

To alleviate the above-mentioned hypertrophic change of the lateral limbs, we modified the conventional Z-plasty and invented a new technique. Because the shape of the flap resembles a bird's beak, we call the technique “beak-plasty.” The purpose of this study is to present the new technique. METHODS

The technique is described and effectiveness of the technique is reviewed on 21 patients. In particular, three representative cases are presented with photographs. RESULTS

In all patients, the lateral limbs of the flaps did not become hypertrophic after a minimum follow-up period of 9 months. CONCLUSIONS

Our technique can effectively reduce Z-plasty's risk of postoperative hypertrophy in the lateral limb. Therefore, it can make the scar less conspicuous than in conventional Z-plasty. For this advantage, we recommend our technique as an effective armament for scar revision.
