Figure 1. Pre- and postoperative hearing (air conduction pure-tone average) among different types of chronic middle ear diseases. Bold horizontal lines, means; whiskers, standard deviation. Ch., cholesteatoma; COM, chronic otitis media; w/, with; w/o, without.
Figure 2. Pre- and postoperative health-related quality of life assessed by the ZCMEI-21 among different types of chronic middle ear diseases. (A ) Preoperative ZCMEI-21 total scores. (B ) Postoperative ZCMEI-21 total scores. (C ) ZCMEI-21 total score shifts. A negative value indicates a postoperative decrease in the ZCMEI-21 total score suggesting an improvement in health-related quality of life. The minimal clinically important difference (MCID) is indicated by the dotted line. Statistically significant differences between mean pre- and postoperative ZCMEI-21 total scores are indicated by asterisks (*, p < 0.05; **, p < 0.01; ***, p < 0.001; for exact p-values, see text). Bold horizontal lines, means; whiskers, standard deviation. Ch., cholesteatoma; COM, chronic otitis media; n. s., not significant; w/, with; w/o, without.

(A–B ) Pre- (A) and postoperative (B) ear discharge as assessed by question 2 (Q2) of the ZCMEI-21. (C–D ) Pre- (C) and postoperative (D) vertigo/balance problems as assessed by question 5 (Q5) of the ZCMEI-21. Bold horizontal lines, means; whiskers, standard deviation. Ch., cholesteatoma; COM, chronic otitis media; n. s., not significant; w/, with; w/o, without.
