BACKGROUND AND AIM: A Z-plasty flap is one of the most widely used geometric relaxation methods to release contracture bands. A rhomboid flap is a lesser used geometric relaxation method than a Z-plasty flap. This study aimed to determine the length and rate of elongation provided by rhomboid and Z-plasty flaps.
METHODS: Bilateral contracture bands were created in the inguinal skins of rats. A rhomboid flap was planned for the right side of the inguinal region, and a single Z-plasty flap was planned for the left side. The length and rate of elongation provided by the two flaps were calculated after completing the procedures and were compared using Student's t-test.
RESULTS: Experimental contracture bands disappeared in both the inguinal regions after creating rhomboid and Z-plasty flaps. The mean postoperative elongation of the contracture band was 1.4 ± 0.119 and 2.47 ± 0.281 cm using the rhomboid and Z-plasty flaps, respectively. The difference was statistically significant (p < .001).
CONCLUSION: Z-plasty flaps provide more elongation than rhomboid flaps and also appear to be better options for releasing linear contracture bands. However, rhomboid flaps may be used as alternatives when Z-plasty flaps cannot be used and in regions such as the axilla, genital region, nipple-areola, where their distortion effects should be avoided.
