All pediatric patients diagnosed with cholesteatoma who underwent primary canal wall-up tympanomastoidectomy with or without ossicular reconstruction from 2009 to 2016 at a tertiary university-affiliated pediatric medical center were included. Pure tone average (PTA) and air-bone gap (ABG) at 0.5, 1, 2, and 4 kHz were compared before and after surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The cohort included 100 children (104 tympanomastoidectomies) of mean age 10.35 \u00b1 3.6 years. The mean duration of follow-up was 35.4 \u00b1 24.1 months. At surgery, 22 patients (21.2%) had intact ossicular chains, and 82 (78.8%) had ossicular discontinuity. Fifty-three patients (51%) underwent ossicular reconstruction, either partial (34 patients [64.1%]) or total (19 patients [35.8%]). In comparison with preoperative audiometry, there was a statistically significant improvement in PTA-ABG at the first postoperative examination (27.5 \u00b1 12.7 vs 21.1 \u00b1 11.1 dB, P = .001) and at the end of follow-up (20.2 \u00b1 12.7 dB, P = .003) . Overall, values of less than 20 dB were measured in 34% of patients preoperatively and 73% postoperatively. On subgroup analysis, in patients who underwent any ossicular reconstruction, PTA-ABG was significantly improved relative to the preoperative value (28.1 \u00b1 14.7 dB) at both the first (19.1 \u00b1 11.9 dB, P = .006) and last (22.4 \u00b1 15.1 dB, P = .011) audiometry examinations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Hearing outcomes after pediatric cholesteatoma surgery are diverse and related to several factors.
