The postoperative pure-tone average air\u2013bone gap (PTA-ABG) was calculated, and two criteria of successful hearing outcomes were defined as \u226410 and \u226420 dB. Patients were classified according to the EAONO\/JOS and 2015 JOS staging systems. Cochran\u2013Armitage test was used to statistically analyze staging, and Fisher\u2019s exact test was used to analyze other factors.\n\n\t\u00a0\n\n\tRESULTS: Successful hearing outcome with postoperative PTA-ABG \u226410 and \u226420 dB occurred in 23.5% and 55.9% of cases, respectively. When postoperative PTA-ABG \u226420 dB was defined as successful, the success rate significantly decreased with increase in EAONO\/JOS stage, and S0 pathological status of the stapes (no involvement) was a significantly favorable predictive factor. When postoperative PTA-ABG \u226410 dB was regarded as successful, the significantly favorable predictive factors were S0 pathological status of the stapes and development of mastoid cells with MC2\u20133 (better developed cells).\n\n\t\u00a0\n\n\tCONCLUSION: Favorable prognostic factors for hearing outcomes of tympanomastoidectomy with partial ossicular reconstruction for primary pars flaccida cholesteatoma were low stage following the EAONO\/JOS staging system and no stapes involvement and better development of mastoid cells following the 2015 JOS staging system.\n\n\t\u00a0\n\n\tCite this article as: Fukuda A, Morita S, Nakamaru Y, Hoshino K, Fujiwara K, Homma A.
