OBJECTIVE To explore nasolabial movements in participants with repaired cleft lip and palate. DESIGN A parallel, three-group, nonrandomized clinical trial. SUBJECTS Group 1=31 participants with a cleft lip slated for revision surgery (revision), group 2=32 participants with a cleft lip who did not have surgery (nonrevision), and group 3=37 noncleft(More)
OBJECTIVE In patients with cleft lip and palate, the aim of the study was (1) to determine and compare the level of agreement among examiners' subjective evaluations of static and dynamic lip form; (2) assess possible bias of examiners' subjective evaluations; and (3) determine the impact of lip scarring on an examiner's subjective assessment of dynamic lip(More)
PURPOSE The purpose of this study was to determine the facial movement characteristics of patients who underwent orthognathic surgery. The specific aims were to determine the presurgery versus postsurgery differences in facial movements; to determine whether the presurgery facial movements were similar among patients with different dentofacial deformities;(More)
OBJECTIVE Children with a cleft of the upper lip exhibit obvious facial disfigurement. Many require multiple lip surgeries for an optimal esthetic result. However, because the decision for lip revision is based on subjective clinical criteria, clinicians may disagree on whether these surgeries should be performed. To establish more reliable, functionally(More)
OBJECTIVE To investigate lip force dynamics among participants with a repaired cleft of the lip and noncleft control participants. DESIGN A parallel, three-group, nonrandomized clinical trial. SUBJECTS Forty-eight participants with cleft lip and 36 noncleft participants. ANALYSIS Participants attended two separate visits. At each visit, they were(More)
PURPOSE To introduce a novel approach to analyze and model facial movements; and to quantify variations in facial movement caused by the extent of skeletal differences between the maxilla and mandible and the middle to lower facial heights. The hypothesis was that there are differences in facial movement related to the underlying facial skeleton which may(More)
OBJECTIVE In patients with cleft lip and palate, the aims of this study were to generate objective measures of different attributes of lip movement and to explore the utility of these objective measures by examining the association between examiners' subjective assessments with the objective measures. PATIENTS AND PARTICIPANTS Thirteen patients with(More)
OBJECTIVE To measure and compare the perioral stiffness among three groups of pediatric subjects: a group of patients with a repaired cleft lip (and palate) who had a secondary lip revision surgery (revision), another group of patients with repaired cleft lip (and palate) who did not have secondary surgery (nonrevision), and a group of noncleft "normal"(More)
Objectives :  (1) To collect three-dimensional, dynamic facial images from two groups of infants: one group born with cleft lip and palate slated to have a primary lip repair and a second, age-matched, noncleft control group. (2) To develop analyses to determine differences in facial movement between infants with cleft lip with or without palate (CL±P) and(More)
