The O-Z flap is the most commonly used local flap technique to repair round and oval scalp defects in clinical practice. Preoperative flap marking is one of the major technical issues of this reconstructive method and it is essential to achieve an optimal outcome. Nevertheless, the absence of a unified arc design scheme could significantly limit the use of this useful and reliable technique, and flap drawing is sometimes based more on the surgeon's experience than on a real geometrical model. Our aim was to describe an intuitive and standardizable method for O-Z flap marking, that we called "O-S flap," based on a simple and easily replicable geometrical pattern. We reported our experience in this case series of eight patients with skin tumors of the scalp who underwent scalp reconstruction with the "O-S flap" technique at our university hospital. Most patients had defects located on the vertex or parieto-occipital regions of the scalp. The area of the defects ranged from 7 to 78.5 cm. There were no cases of flap necrosis, wound infection, or positive margins, and no patients required revision surgery. We believe that our technical refinement represents a safe, easy, and reproducible method for O-Z flap marking. It follows a simple geometrical model which could be customized according to different clinical needs.
O-Z皮瓣是临床实践中修复圆形和椭圆形头皮缺损最常用的局部皮瓣技术。术前皮瓣标记是这种重建方法的主要技术问题之一，实现最佳效果至关重要。然而，缺乏统一的弧形设计方案可能会严重限制这种实用且可靠技术的应用，皮瓣绘制有时更多地基于外科医生的经验而非真实的几何模型。我们的目的是描述一种直观且可标准化的O-Z皮瓣标记方法，我们称之为“O-S皮瓣”，它基于一种简单且易于复制的几何图案。我们报告了在我们大学医院对8例头皮皮肤肿瘤患者采用“O-S皮瓣”技术进行头皮重建的这一系列病例中的经验。大多数患者的缺损位于头皮的顶点或顶枕部区域。缺损面积为7至78.5平方厘米。没有皮瓣坏死、伤口感染或切缘阳性的病例，也没有患者需要进行修复手术。我们认为我们的技术改进代表了一种安全、简便且可重复的O-Z皮瓣标记方法。它遵循一个简单的几何模型，可根据不同的临床需求进行定制。
