All cases with mixed microscopic\/endoscopic, fully endoscopic, or fully microscopic dissection were excluded, as well as cases where a canal wall-down technique was used. After microscopic cholesteatoma removal, the otoendoscope was used to inspect the middle ear recesses for intraoperative cholesteatoma residues. The intra- and postoperative cholesteatoma residue rate were evaluated.\n\nRESULTS: On endoscopic examination, intraoperative cholesteatoma residues were encountered in 24 patients (30%). A total of 30 foci were detected. Most of them were found in the superior retrotympanum (15 foci). In 9 cases an antral remnant guided the surgeon to convert to a canal wall up tympanomastoidectomy. During the postoperative follow-up period, residual cholesteatoma was detected on postoperative magnetic resonance imaging in 6 patients (7.5%). Adding an otoendoscopic examination to microscopic cholesteatoma surgery reduced the postoperative cholesteatoma residues rate (odds ratio=0.16). A negative otoendoscopic examination led to a cholesteatoma residue-free follow-up period in 95% of cases(NPV=0.95).\n\nCONCLUSION: Otoendoscopy is effective in identifying intraoperative cholesteatoma residues after microscopic cholesteatoma surgery. It reduces the postoperative cholesteatoma residue rate, and a negative otoendoscopic examination increases the likelihood of a cholesteatoma residue-free follow-up.\n\nCite this article as: Couvreur F, Loos E, Desloovere C, Verhaert N.
