Effect of Chin Tuck Maneuver on Aspiration and Pharyngeal Residues Evaluated Using Simultaneous Videofluoroscopic Swallowing Study and Fiberoptic Endoscopic Evaluation of Swallowing / 대한연하장애학회지

ABSTRACT

OBJECTIVE: To evaluate the effect of chin tuck maneuver on aspiration and pharyngeal residue using both videofluoroscopic swallowing study (VFSS) and fiberoptic endoscopic evaluation of swallowing (FEES). METHOD: Subjects with dysphagia were trained by occupational therapists for chin tuck maneuver at least for a week. After training, all participants underwent VFSS and FEES simultaneously with each neutral and chin tuck posture with various tests diets. The modified penetration-aspiration scale (mPAS) and a new scale for pharyngeal residue were used for evaluation of aspiration and pharyngeal residue. RESULT: A total of 35 patients (mean age, 64.2±12.1 years) were included. A significant change in the mPAS was caused by chin tuck posture in thin liquid (P=0.02) only in the VFSS evaluation. The vallecular residues were decreased by chin tuck posture in rice porridge (right, P=0.01; left, P=0.009), and thin liquid (right, P=0.007; left, P=0.01). The pyriform sinus residues were also decreased by chin tuck posture in rice porridge (right P=0.02; left P=0.03), curd-type yogurt (right, P=0.02; left, P=0.005), and thin liquid (right, P=0.001; left, P=0.003). CONCLUSION: Chin tuck maneuver is effective in preventing penetration or aspiration and in decreasing pharyngeal residues when evaluated by simultaneous VFSS and FEES.
