Evaluation of Swallowing Impairment After Tonsillectomy

Using flexible endoscopy, the patient will be given a colored thin fluid to keep in their mouth and then swallow following the instructions of the examiner, then the examination will be repeated using semisolids (1 teaspoon of yogurt) and using solids (piece of bread). The evaluation of swallowing will involve four items: early spill of food (delayed triggering), aspiration, penetration, and retention (residue). And the results will be recorded.
