Evaluation of Continuous Z-Plasty Technique for Linear Scar Repair on the Face: A Retrospective Analysis

OBJECTIVE: This study aims to evaluate the efficacy and safety of the continuous Z-plasty technique for repairing facial linear scars and to assess patient satisfaction. METHODS: A retrospective analysis was conducted on patients with facial linear scars who underwent continuous Z-plasty at the authors’ institution from January 2020 to December 2022. Inclusion criteria were patients with facial linear scars, excluding those with other complex facial injuries. Surgical details, preoperative and postoperative Vancouver Scar Scale scores, scar width, and patient satisfaction survey results were collected and analyzed. RESULTS: This study included 21 patients (9 males, 12 females) with a mean age of 36.7 years. The frontal area was the most common location. Hypertrophic scars were present in 4 cases, superficial atrophic in 8, and normal in 9. The median time since scar formation was 14 months. Vancouver Scar Scale scores decreased from a median of 8 preoperatively to 3 postoperatively, with scar widths reducing from 4.5 to 1.5 mm. Follow-up at a median of 18 months showed no recurrence or complications, with significant aesthetic improvement. Comparative photos before and after surgery clearly demonstrated an improvement in scar appearance. CONCLUSION: Continuous Z-plasty has proven to be both an effective and safe approach for improving the appearance of facial linear scars. It not only enhances aesthetic outcomes but also boosts patient satisfaction. Future research should focus on evaluating its long-term results and comparing its effectiveness with other treatment options.
