Our findings also showed a trend toward a better hearing improvement in EES without stapes superstructure when preoperative A-B Gap ≤52 dB HL [ r = 0.730, Adjusted R 2 = 0.516, F (1, 28) = 31.870, P < .001, y = 0.723 x −8.123], whereas MES have better hearing improvement when preoperative A-B Gap >52 dB HL [ r = 0.752, Adjusted R 2 = 0.548, F (1, 25) = 32.511, P < .001, y = 0.925 x −18.611] ( Figure 5 ).
