背景资料：鉴于越来越多地使用真皮填充物进行美容丰唇，在临床上需要一种经验证的仪器来测量唇部丰满度，并将其作为临床研究中的疗效终点。作者开发并对美第奇开发的嘴唇丰满度量表进行了验证研究。方法：美第奇嘴唇丰满度量表由上唇和下唇的单独五点量表组成，每个等级有三张照片作为示例。第一轮验证（照片对比）中，五位委员会认证的皮肤科医生或整形外科医生在两个不同的场合评估了每个嘴唇的85张测试照片。三个评价者还在39个现场受试者的嘴唇丰满度进行了分级，2周后，由相同的主题的第二轮验证（现场与摄影）的照片评分。结果：两个连续的摄影评价之间的观察者内的协议几乎是完美的（加权Kappa = 0.81）。观察者间加权Kappa值范围为上唇0.60 - 0.83，下唇0.61 - 0.82。同一主题的现场和摄影评估之间的准确协议分别为60%和52%for上，下lips.Conclusions：美第奇唇丰满度量表显示出较高的interrater和intrarater的测试照片和中度到大量的患者与照片的现场评估的可靠性比较的可靠性。Medicis唇部丰满度量表适用于临床试验中对唇部丰满度进行分级。（Plast。重建129：822e，2012）。
Background: Given the growing use of dermal fillers for cosmetic lip augmentation, a validated instrument with which to measure lip fullness is desirable in the clinic and as an efficacy endpoint in clinical studies. The authors developed and conducted a validation study of a Medicis-developed lip fullness scale.Methods: The Medicis Lip Fullness Scale consists of separate five-point scales for the upper and lower lips, with three photographs exemplifying each grade. Five board-certified dermatologists or plastic surgeons assessed 85 test photographs for each lip on two separate occasions for the first round of validation (photograph versus photograph). Three of the evaluators also graded lip fullness in 39 live subjects, followed 2 weeks later by scoring of the same subjects' photographs for the second round of validation (live versus photographic).Results: Within-observer agreement between the two sequential photographic evaluations was almost perfect (weighted kappa = 0.81). Between-observer weighted kappa values ranged from 0.60 to 0.83 for the upper lip and 0.61 to 0.82 for the lower lip. Exact agreement between the live and photographic assessments of the same subjects was 60 percent and 52 percent for upper and lower lips, respectively.Conclusions: The Medicis Lip Fullness Scale showed high interrater and intrarater reliability in comparisons of test photographs and moderate to substantial reliability in live assessment of patients versus photographs. The Medicis Lip Fullness Scale is suitable for grading lip fullness in clinical trials. (Plast. Reconstr. Surg. 129: 822e, 2012.)
