The dry ear rate at the most recent outpatient clinic visit (median 28.0\u00a0months postoperative) was significantly higher in the obliteration group with 96.4% compared to 73.9% for the non-obliteration group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u2009.002).
