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 To analyze and display facial movement data from noncleft subjects and from patients with cleft lip and palate by using a new dynamic approach. The hypothesis was that there are differences in facial movement between the patients with cleft lip and palate and the noncleft subjects. SETTING Subjects were recruited from the University of North(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)
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 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)
This study determined the accuracy of a camera system capable of recording three-dimensional facial images. A Rainbow 3D Camera Model 250 system (Genex Technologies Inc, Kensington, Md) was used to capture images of specific models: (1) a precalibrated precision model and (2) a mannequin model that served to simulate the human condition. To assess the(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)
OBJECTIVE Compare neurosensory assessments for participants with and without a cleft lip; identify between- and within-participant variables affecting sensory thresholds on the vermilion of participants with cleft lip. DESIGN A parallel group, nonrandomized clinical trial. SUBJECTS There were 56 participants with cleft lip and 37 noncleft participants.(More)
