Mean age at diagnosis was 7.9\u2009years and 77 (28%) were congenital. Almost all patients (99%) had a canal wall up approach. The mean follow\u2010up was 97.8\u2009months. The Potsic classification, initially designed for congenital cholesteatoma, had the highest AUCs for residual disease rate and for number of surgeries outcomes (respectively 0.73 [0.67\u20130.78] and 0.71 [0.66\u20130.77]). For recurrence rate, all the classifications' C\u2010index were low (&lt;0.7). For postoperative hearing, STAMCO ossicular subscore had the highest AUC (0.73 [0.67\u20130.79]). The Mod\u2010Pot staging system (modified Potsic), including stapes superstructure status and anterior epitympanum or supratubal involvement, improved the Potsic performance especially for postoperative hearing with AUC 0.73 [0.67\u20130.80],\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The Potsic, ChOLE, EAONO\/JOS, and STAMCO cholesteatoma classifications may be used in children, but in this specific population, their contribution remains limited to predict outcome.
