Can Myringoplasty Close the Air-Bone Gap?

Abstract

Complete ABG closure by myringoplasty could be achieved in only approximately 20% of the cases. 80% respectively presented with a mean residual ABG of 8 dB. We found a significant linear correlation between the preoperative size of the tympanic membrane perforation and the postoperative ABG, whereas mastoid volume, temporal bone pneumatization, and the condition of the mucosa did not affect the outcome.
