Comparative Evaluation of Wet and Dry Swallowing in Assessing Eustachian Tube Function in Tympanic Membrane Perforation.

Although pressure change was found to be relatively larger in the wet than in the dry phase, this difference failed to reach significance (mean = 93.33 ± 12.35 daPa of pressure change in the wet phase; mean = 92.00 ± 13.89 daPa of pressure change in the dry phase; Z = -0.445; p = 0.530) in swallow 2 and (mean = 75.71 ± 14.05 daPa of pressure change in wet phase; mean = 74.58 ± 16.96 daPa of pressure change in dry phase; Z = -0.796; p = 0.562) in swallow 3.
