Considering that microscopes only offer line-of-sight vision, it was suggested earlier that endoscopes might prove useful to control difficult-to-visualize areas during surgery to ensure total evacuation of squamous epithelium. In this retrospective chart study, we evaluated intraoperative endoscopic findings of difficult-to-access sites in the tympanic cavity and postoperative cholesteatoma recidivism rate in these areas in a patient cohort who underwent primarily microscopic surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main findings:<\/jats:title>\n                    <jats:p>Residual cholesteatoma mass was intraoperatively detected in difficult-to-visualize areas using an endoscope during 50% of the procedures (10 cases), mostly in the sinus tympani (6 cases), but also in the supratubal recess (3 cases). During a mean follow-up of 36.1\u2009months (range: 20-59\u2009months, targeted magnetic resonance imaging [MRI] mean follow-up: 31.3 [range: 12-59]), recurrent attic cholesteatoma was found in 2 patients (10%), and residual disease was detected with dedicated MRI sequences in another 2 cases (10%).
