The main reason of bilateral lip asymmetry after cleft lip surgery lies in the lack of personalized measurement and design before surgery. In this study, we aim to individually investigate areas of the upper lip on cleft and non-cleft sides in patients with unilateral cleft lip with or without cleft palate (UCL/P).<h4>Methods</h4>Ninety-two patients with UCL/P (group 1: <1 year, group 2: 1-2 years) were included in the study. Group 1 included 37 patients with incomplete UCL/P and 29 with complete UCL/P; group 2 included 11 and 15 patients, respectively.
