The V-Y advancement flap (VYF) is not commonly used to reconstruct defects located on the medial cheek. The quantitative assessment of VYF for this indication has not been reported. In evaluation of surgical scarring, the Patient and Observer Scar Assessment Scale (POSAS) has been validated for use in burn and breast surgery scars, but its usefulness in dermatologic surgery has not been determined.
To present our experience with the use of the POSAS to assess the success of VYF reconstruction for surgical defects on the medial cheek.
Fourteen patients with medium to large (>5 cm(2) ) medial cheek Mohs defects reconstructed using VYF were assessed. Final cosmetic and functional results were analyzed after a follow-up of 6 months to 2 years (mean follow-up 21 months) using the POSAS.
Observers using the POSAS gave a mean score for VYF reconstructions of 9.1 ± 2.3 (5 represents normal skin, 50 represents worst imaginable scar). Patients using the POSAS gave a mean score for VYF reconstructions of 10 ± 4 (6 representing normal skin, 60 representing worst imaginable scar).
VYF reconstruction of medium to large defects of the medial cheek is a useful option. The POSAS may be a helpful tool for evaluating reconstructive results in dermatologic surgery.
V-Y 推进皮瓣（VYF）并不常用于重建位于内侧脸颊的缺损。对于这种适应症的 VYF 定量评估尚未报道。在评估手术疤痕时，患者和观察者疤痕评估量表（POSAS）已被验证可用于烧伤和乳房手术疤痕，但尚未确定其在皮肤科手术中的有用性。
介绍我们使用 POSAS 评估 VYF 重建内侧脸颊手术缺损的成功经验。
14 名患有中到大（>5cm²）内侧脸颊 Mohs 缺损的患者使用 VYF 进行重建。在 6 个月至 2 年（平均随访 21 个月）的随访后，使用 POSAS 分析最终的美容和功能结果。
观察者使用 POSAS 对 VYF 重建的平均得分为 9.1±2.3（5 代表正常皮肤，50 代表最糟糕的想象疤痕）。患者使用 POSAS 对 VYF 重建的平均得分为 10±4（6 代表正常皮肤，60 代表最糟糕的想象疤痕）。
VYF 重建中到大的内侧脸颊缺损是一种有用的选择。POSAS 可能是评估皮肤科手术重建结果的有用工具。
