Background: The assessment of swallowing pattern is crucial for the diagnosis and management of swallowing disorders.Clinicians can better understand the underlying causes of tongue thrusting/ abnormal swallowing patterns,by using ultrasound to visualize the movement of the tongue, pharynx, and larynx during swallowing and develop appropriate treatment plans. In this study, we aim to use ultrasonography, a non-invasive and costeffective approach to evaluate the swallowing patterns of mature swallowers and those with retained infantile swallow patterns. The dynamics of swallowing in real-time can be assessed in toto by the use of Ultrasonography.
