Resting middle-ear pressure was measured and the nine-step inflation\/deflation test performed on all subjects before flights. Subjects were allocated to two groups according to resting middle-ear pressure range (group A, within the range of +26 to +100 and \u221226 to \u2212100 mmH\n                      <jats:sub>2<\/jats:sub>\n                      O; group B, \u221225 to +25 mmH\n                      <jats:sub>2<\/jats:sub>\n                      O).
