Vallecular and pyriform sinus (PS) residues in the anteroposterior view were analyzed quantitatively. In both regions, the symmetry of the affected versus nonaffected sides between patients with idiopathic UVFP and RLNP were compared. Residual differences between short\u2010 versus long\u2010term paralysis duration in idiopathic UVFP patients alone were also evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The affected PS of the idiopathic group demonstrated significantly increased residue (<jats:italic>P<\/jats:italic>\u2009=\u2009.007) as compared with the nonaffected PS, but with no significant difference with respect to the vallecula (<jats:italic>P<\/jats:italic>\u2009=\u2009.183). There was no significant difference in the RLNP group. When compared with RLNP patients, the idiopathic group showed significantly increased residue on the affected PS (<jats:italic>P<\/jats:italic>\u2009=\u2009.002), but differences in the vallecular residue were nonsignificant.
