Abstract

To evaluate the motion of the face and jaw of patients with cleft lip and palate, facial palsy, and in patients after reconstruction, a motion-analyzing system was developed. The aim of this article was to investigate the accuracy of this system and the possibility of clinical application. Markers of 1 to 2 mm were placed on the face, and motion images were obtained by three digital video cameras controlled by a synchronizer and recorded on digital video tape. The image was processed on a personal computer. The markers were automatically tracked across the image sequences, and their three-dimensional coordinates were then calculated. System accuracy was investigated using a positioning actuator with high accuracy and a known object. In three patients with bilateral cleft lip and palate, lip pursing was analyzed using the aforesaid method. The mean differences from the known values to the distances between the tracked sample points and to the mobile distances of the sample points per frame were 0.24 to 0.36 mm and 0.02 to 0.05 mm, respectively. Both results were similar regardless of the mobile speed or direction. In five repeated measurements, the mean differences from the known values as for the distances and the mobile speed ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
