Table 1
Bolus residue scale (BRS) scores according to the number of structures affected by residue.
| BRS score | Indication of residue |
| 1 | No residue | 2 | Residue in valleculae | 3 | Residue in posterior pharyngeal wall or piriform sinus | 4 | Residue in valleculae and posterior pharyngeal wall or piriform sinus | 5 | Residue in posterior pharyngeal wall and piriform sinus | 6 | Residue in valleculae and posterior pharyngeal wall and piriform sinus |
