“…Tian and Redett (2009) reported mean values from 2D data from 17 adult subjects (five men and 12 women) of different races (11 white and six Chinese) and age (19 to 43 years of age). Due to the known craniofacial and vocal tract variations related to sex, race, and age (Akgüner, 1999; Ettema et al, 2002; Bae et al, 2011b) caution should be taken when making direct comparisons between studies. Data in the present study represent a more homogeneous population compared with data from other similar studies.…”

Objective Direct visualization of the velopharynx and, in particular, the levator muscle is particularly important in the assessment of velopharyngeal function and normal speech production. The purpose of this study is to demonstrate the development of a static and dynamic magnetic resonance imaging protocol for evaluation of velopharyngeal structures and function. Methods A high-resolution, T2-weighted turbo-spin-echo three-dimensional anatomical scan (sampling perfection with application optimized contrasts using different flip angle evolution) was used to acquire a large field of view covering the velopharyngeal anatomy. Dynamic speech assessment was obtained using a fast-gradient echo, fast low-angle shot, multi-shot spiral technique to acquire 15.8 frames per second (fps) of the sagittal and oblique coronal image planes. Results Using a three-dimensional data set, as opposed to two-dimensional data, the full contour of the levator muscle can be appreciated. Dynamic images were obtained at 15.8 fps in the sagittal and oblique coronal planes, enabling visualization of the movements of the velum, posterior pharyngeal wall, lateral pharyngeal walls, and levator muscle during speech. Conclusions A three-dimensional magnetic resonance imaging sequence, such as that used in the present study, may provide better analyses and more precise measurements. A dynamic fast low-angle shot sequence allows for visualization of the levator muscle and the velum during speech at a high image rate. This protocol could have a significant impact in improving the process of visualizing pathology and promoting clinical treatment plans for individuals born with cleft lip and palate.

“…Therefore, MRI has great potential for clinical and research applications. Several investigators have explored the application of MRI to the evaluation of the velopharyngeal mechanism (McGowan et al, 1992;Akgüner, 1999;Kuehn et al, 2004;Shinagawa et al, 2005;Inoue et al, 2006) and have employed MRI procedures to provide detailed information on specific musculature of the velopharyngeal region (Yamawaki et al, 1996(Yamawaki et al, , 1997Ettema et al, 2002). Kuehn et al (2001Kuehn et al ( , 2004 explored the usefulness of MRI to image the velopharyngeal region in infants with submucous cleft palate or cleft palate before and after primary palatoplasty, with particular emphasis on the LVP muscle due to its importance for speech and swallowing purposes.…”

“…Soft palate function and development can be monitored and recorded by nasopharyngeal fibroscope and magnetic resonance imaging methods. [7][8][9][10] However these methods are costly and are subjected to availability. Cephalometric analysis is commonly used to depict the soft palate morphologies in normal individuals and in cleft lip and palate patients.…”

Background: The literature describes the morphology of the soft palate as being of only one kind and ignores its diversity, but in clinical work the morphology of the soft palate has a variable presentation on lateral cephalometry. Soft palate plays a significant role in various important functions in the head and neck region. Its varied morphology is implicated in various diseases. Study is aimed to investigate the variation of soft palate morphology in different age and gender groups. Materials & Methods: In this study, the sample comprised 202 normal subjects whose age ranged from 6-50 years. The morphology of the soft palate on lateral cephalometry was analyzed for velar morphology and categorized into different types. The dimensional differences of the soft palate between each type and the differences in proportion to different age and gender groups were studied. Results & Conclusion: The morphology of soft palate was divided into six varieties as was previously described there were significant difference in the velar length in preadults and adults. Type 1 soft morphology was the most common morphology present. Also there was statistically significant difference in length of type 3 morpholgy from rest 5 morphological varieties studied.
