OBJECTIVE 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. METHODS Markers of 1 to 2 mm were placed on the face,(More)
To analyze the lip movement of patients with cleft lip and palate in detail, we developed a novel technique to produce a range image from a video-based motion capture system, and a unique technique to analyze lip movements in detail three-dimensionally. The accuracy of the range image obtained from the present system was investigated using a positioning(More)
To quantify the shape of cleft lip noses and to evaluate the outcome following rhinoplasty objectively, a three-dimensional measuring system for the nasal shape was developed using a contact-type measuring apparatus. In this system, the surface data for a face could be obtained accurately, and facial landmarks could be identified semiautomatically. A new(More)
Palatogenesis is directed by epithelial-mesenchymal interactions and results partly from remodeling of the extracellular matrix (ECM) of the palatal shelves. Here, we assessed heparanase distribution in developing mouse palates. No heparanase was observed in the vertically oriented palatal shelves in early stages of palate formation. As palate formation(More)
OBJECTIVES The aim of the present study was to determine whether there are dialectal and gender-related differences in nasalance scores for normal Japanese speakers. MATERIALS Sixty-eight volunteers consisting of 31 males (age 23.8+/-2.0) and 37 females (age 23.2+/-2.5) were included in this study. They had no diseases affecting speech, and lived in the(More)
