“…According to the results for the second criterion, the threshold at low frequencies had a higher prognostic value. This is in agreement with the findings of several previous studies that have shown better postoperative hearing improvement at lower frequencies than at higher frequencies 25,26 . To elaborate, the cutoff values for preoperative BC and preoperative ABG were 16.0 dB and 21.3 dB, respectively, and hearing levels higher than these values resulted in better hearing outcomes.…”

Regarding the TM perforation size, our results indicate that a larger perforation is associated with a better hearing outcome.…”

ObjectiveTo evaluate the performance of a machine learning model and the effects of major prognostic factors on hearing outcomes following intact canal wall (ICW) mastoidectomy with tympanoplasty.Study DesignRetrospective cross‐sectional study.SettingTertiary hospital.MethodsA total of 484 patients with chronic otitis media who underwent ICW tympanomastoidectomy between January 2007 and December 2020 were included in this study. Successful hearing outcomes were defined by a postoperative air‐bone gap (ABG) of ≤20 dB and preoperative air conduction (AC)‐postoperative AC value of ≥15 dB according to the Korean Otological Society guidelines for outcome reporting after chronic otitis media surgery. The light gradient boosting machine (LightGBM) and multilayer perceptron (MLP) models were tested as artificial intelligence models and compared using logistic regression. The main outcome assessed was the successful hearing outcome after surgery, measured using the area under the receiver operating characteristic curve (AUROC).ResultsIn the analysis using the postoperative ABG criterion, the LightGBM exhibited a significantly higher AUROC compared to those of the baseline model (mean, 0.811). According to the difference between preoperative and postoperative AC, the MLP showed a significantly higher AUROC than those of the baseline model (mean, 0.795).ConclusionThis study analyzed multiple factors that could affect the hearing outcome using different artificial intelligence models and found that preoperative hearing status was the most important factor. Our findings provide additional information regarding postoperative hearing for clinicians.
