Objective: To investigate the rate of elongation provided by subcutaneous pedicle rhomboid flap.
Material and Methods: Lower extremities of 20 male Sprague-Dawley rats were strained and fixed on a table to provide a tension line over the inguinal area. Twenty subcutaneous pedicle rhomboid flaps, with 2 cm long axis and with 120 and 60-degree angles, were designed over the inguinal tension lines of each rat. Flaps were incised down to the muscle and freed from the stretched skin. Skin tension lines were relieved by relaxation incisions which were made in the ‘cut as you go’ manner. The emerged defects were then closed by suturing the rhomboid flaps in V-Y advancement along the tension lines and in Y-V advancement along the relaxation incisions. The final elongation was measured and the results were statistically analyzed.
Results: All relaxation incisions were effective in relief of tension over the inguinal area and in lengthening the tension line. Two cm long preoperative length ranged between 3.9 cm to 4.3 cm postoperatively (mean ± standard deviation= 4.08 ± 0.13 cm). The mean difference between pre- and post-operative measurements was 2.08 cm, which was a 104% gain in length. The subcutaneous pedicle rhomboid flaps easily closed all defects generated by relaxation and elongation. Statistical analysis revealed that a single subcutaneous pedicle rhomboid flap, with 120 and 60-degree angles, was efficient to close a defect generated by the relaxation incisions that produced a 104% gain in length.
Conclusion: As a result subcutaneous pedicle rhomboid flap may be a good alternative technique in the treatment of postburn scar contractures. The technique is simple, reliable and the rate of elongation provided by the technique compares favorably with commonly used Z-plasty.Keywords: Surgical flap, rats, burnsTurkiye Klinikleri J Med Sci 2005, 25:806-809
