Differences in Velopharyngeal Structure during Speech among Asians Revealed by 3-Tesla Magnetic Resonance Imaging Movie Mode

Figure 5

Time-to-time changes in the velopharyngeal structures of Japanese and Thai subjects. The graphs show the dimensional changes in each area of interest: velopharyngeal depth (a), velar length (b), velar thickness (c), and retroglossal space (d). The -axis shows the measurement stages and the -axis shows the distance in millimeters. ; NS: not significant.
