Background: Staged purse-string suturing has been recently introduced for the reconstruction of round or oval defects following tumor excision. Objective: The aim of this study was to evaluate the clinical advantage of staged purse-string suturing for the reconstruction of relatively large skin defects. Materials and Methods: Twenty-one patients who received staged purse-string sutures were included in the study. To evaluate the defects and scar sizes objectively, computer-based image analysis was used. A modified observer scar assessment scale (OSAS) was applied for evaluating the clinical efficacy. Results: The mean primary postsurgical defect size in the total 21 cases was 1446.2 ± 1187.2 mm2, and the mean final scar size was about 268.1 ± 252.3 mm2. The defect area decreased gradually as staged purse-string suturing was performed. The mean total modified OSAS was 7.96 ± 1.69. Conclusion: Staged purse-string sutures might be an alternative reconstructive method for relatively large round or oval skin defects.
