Effects of lip revision surgery in cleft lip/palate patients

The decision for lip revision surgery in patients with repaired cleft lip/palate is based on surgeon subjective evaluation of lip disability. an objective evaluation would be highly beneficial for the assessment of surgical outcomes. in this study,the effects of lip revision on circumoral movements were objectively quantified. the hypothesis was that lip revision increases scarring and impairment. the study was a non-randomized clinical trial that included patients with cleft lip who had revision,patients with cleft lip who did not,and non-cleft control individuals. three-dimensional facial movements were measured. revision patients were measured before and after surgery. other individuals were measured at similar intervals. regression models were fit to summary measurements,and changes were modeled. patients with repaired cleft lip/palate had fewer mean movements than control individuals. lip revision did not worsen mean movements; however,individual patient movements varied from improvement to no change to worse relative to those of control individuals.
