“…While it is possible that the position of the subject may have affected tongue functioning in the present study, the effect would have been similar for all subjects, including controls, and would not have influenced intergroup comparisons. Nevertheless, the natural function of the tongue may have been influenced by the position of the subjects in this study and contributed to some extent to the differences between the results of this study and those obtained using other visualization techniques 21,27…”

“…This promising dynamic diagnostic modality has the advantages of noninvasiveness, absence of radiation exposure, and the ability to image soft-tissue anatomy during motion in a multiplanar mode 1,2,16,24,27,28. Panebianco et al28 were able to obtain good-quality images using a temporal resolution of 3 - 4 slices/seconds, thereby demonstrating that dynamic MRI is a very promising tool in the evaluation of normal pharyngeal anatomy and physiology.…”

“…Further, the availability of turbo fast low-angle shot acquisition provides the best anatomical and functional information available to evaluate the process of swallowing 1,24,28. We chose to evaluate the movement of the HB by using dynamic MRI for its noninvasive nature and reliability, which have been successfully shown in previous studies 1,22,24,27,28. Accordingly, a TFE sequence was implemented to evaluate the HB and related pharyngeal structures in the present study.…”

“…Numerous reports in the literature1,22,24,27,28 have referred to the use of kinetic MRI techniques for the evaluation of swallowing in the supine position. The tongue position and function may be affected when a subject is in the supine position, since the tongue can slip into the throat, making it difficult to swallow.…”

“…In addition to several other techniques,1-4,7,15,18-26 dynamic (cine) magnetic resonance imaging (MRI) is a non-invasive method that is now being used in the evaluation of the swallowing function 1,22-25,27,28. We used this technique in the current study to determine the maximum swallowing-induced superior and anterior displacement of the HB in subjects with skeletal Class III malocclusion.…”

ObjectiveThe displacement of the hyoid bone (HB) is a critical biomechanical component of the swallowing function. The aim of this study was to evaluate the swallowing-induced vertical and horizontal displacements of the HB in subjects with 2 different magnitudes of skeletal Class III malocclusion, by means of real-time, balanced turbo-field-echo (B-TFE) cine-magnetic resonance imaging.MethodsThe study population comprised 19 patients with mild skeletal Class III malocclusion, 16 with severe skeletal Class III malocclusion, and 20 with a skeletal Class I relationship. Before the commencement of the study, all subjects underwent cephalometric analysis to identify the nature of skeletal malformations. B-TFE images were obtained for the 4 consecutive stages of deglutition as each patient swallowed 10 mL of water, and the vertical and horizontal displacements of the HB were measured at each stage.ResultsAt all stages of swallowing, the vertical position of the HB in the severe Class III malocclusion group was significantly lower than those in the mild Class III and Class I malocclusion groups. Similarly, the horizontal displacement of the HB was found to be significantly associated with the severity of malocclusion, i.e., the degree of Class III malocclusion, while the amount of anterior displacement of the HB decreased with an increase in the severity of the Class III deformity.ConclusionsOur findings indicate the existence of a relationship between the magnitude of Class III malocclusion and HB displacement during swallowing.
