Peak ME pressures were recorded during catheter insertion, inflation, deflation, and removal. A second pressure measurement was taken 15\u00a0seconds after each stage to assess the residual pressures. All BET procedures were repeated at least once. Where transmastoid recordings were made, BET was repeated, measuring pressure via a myringotomy to ensure equivalence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Data from 25 procedures in 13 ears (9 heads) were analyzed. A consistent pattern of ME pressure change was observed in all cases. Positive pressures occurred on insertion (maximum, 26 daPa) and inflation (maximum, 99 daPa) and negative pressures on deflation (maximum, \u201346 daPa) and removal (maximum, \u201342 daPa).
