Aesthetic units (AUs) and zones of adherence (ZA) have been previously described in the face; however, a systematic classification of AUs and ZAs together with a unified approach to planning surgery has not been previously described for head and neck surgery. The five principles of surgical planning necessitate respect for AUs, ZAs, and flexion creases; correct scar orientation; and replacing tissue "like for like" by adhering to the four "Ts" of reconstruction (tone, texture, type, and thickness of skin and subcutaneous tissue).
Images of male and female patients and stock images (from iStock) were reviewed and analyzed.
AUs and ZAs were described and tabulated.
Surgical planning necessitates respect for AUs and ZAs and avoidance of maneuvers that will transgress aesthetic unit interfaces or eliminate AUs. An aesthetic atlas of AUs and ZAs is useful for planning surgery, preventing errors, and optimizing aesthetic results.
面部美学单位（AUs）和附着区（ZAs）此前已有描述；然而，头颈部手术中尚未有关于美学单位和附着区的系统分类以及统一的手术规划方法。手术规划的五项原则要求尊重美学单位、附着区和皮肤褶皱；正确的瘢痕方向；以及通过遵循重建的四个“T”（皮肤和皮下组织的张力、质地、类型和厚度）“以相似组织替代相似组织”。
对男性和女性患者的图像以及库存图像（来自iStock）进行了审查和分析。
描述并列出了美学单位和附着区。
手术规划需要尊重美学单位和附着区，并避免跨越美学单位界面或消除美学单位的操作。美学单位和附着区的美学图谱有助于手术规划、防止失误并优化美学效果。
