Hearing Evaluation
Hearing evaluation indicates that the endoscopic myringoplasty significantly decreased the mean preoperative pure-tone average (PTA) from 43.18 ± 14.57 dB HL to 27.08 ± 9.36 dB HL six months after the operation (P =0.002). Similarly, the mean preoperative ABG was measured to reduce from 19.05 ± 5.72 dB HL to 9.36 ± 3.75dB HL (P =0.0019) at the six-month follow-up, as shown in Table 2.
