ET: endoscopic tympanoplasty; MT: microscopic tympanoplasty; ABG:
air-bone gap; RCT: randomized controlled trial.
Note: Additional maneuvers refer to performing canaloplasty, posterior
wall curettage or both on the EAC. They are necessary in some cases for
better visualization and ossicular assessment.
