Computed tomography findings correlated with: recurrent cholesteatoma when attic opacification and ossicular chain involvement were present; and revision surgery type. Sinodural angle disease, posterior canal wall erosion and dehiscent dura were identified as predictors of canal wall down tympanomastoidectomy. Patients with pre-operative computed tomography scans had a higher rate of cholesteatoma recurrence, younger age at diagnosis of recurrent disease, more revision surgical procedures and less time between previous and revision surgical procedures (all\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0022215120002698_sec_a4\" sec-type=\"conclusions\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Pre-operative imaging and intra-operative findings have important clinical implications in revision surgery for chronic otitis media.
