目的本研究的目的是帮助临床医生对寻求唇部年轻化治疗的个体进行管理，并为评估此类治疗的疗效和寿命提供一种客观的方法。方法采用公认的皮肤病分级标准，我们开发并验证了基于数字平行偏振光成像的用于评估嘴唇体积和厚度的照片分级量表。结果照片分级量表是一种有效和可靠的评估嘴唇体积和厚度的工具，具有良好的等级间和等级内一致性。通过与临床评价和三维测量结果的相关分析，验证了该量表的有效性。结论该量表可用于临床试验，以规范临床评价，量化和测量真皮填充物和其他唇部年轻修复手术的寿命。
BackgroundCurrently, there is the need of a validated grading scale for assessing lip volume/thickness.ObjectiveThe aim of this study was to assist clinicians in managing individuals seeking lip rejuvenation and to provide an objective method for evaluating the efficacy and longevity of such treatments.MethodsUsing accepted criteria for the development of dermatological grading scales, we have developed and validated a photographic grading scale for assessing lip volume and thickness based on digital parallel-polarized light imaging.ResultsThe photographic grading scale was shown to be a valid and reliable instrument for assessing lip volume and thickness, with good inter- and intra-grader consistency. The validity of the scale was demonstrated by its correlation with clinical evaluation and 3-dimensional measurements.ConclusionsThis validated lip-volume/thickness grading scale should prove helpful in clinical trial settings to standardize clinical evaluations and to quantify results and measure the longevity of dermal fillers and other procedures for lip rejuvenation.
