Quantitative assessment of the learning curve for cleft lip repair using LC-CUSUM

The first step in cleft lip repair is the precise positioning of anatomical landmarks and tracing of the incisions on the patient's lip at the beginning of the procedure. The aim of this study was to evaluate progress made in learning cleft lip repair tracing using a quantitative assessment of learning curves: LC-CUSUM (learning curve – cumulative sum). Eight surgical residents were enrolled and asked to trace lip repair incisions on five cases of unilateral left cleft lip over 5 consecutive weeks.
