Abstract

Tympanoplasty is a common otologic surgery aimed at repairing tympanic membrane
perforations to improve hearing and prevent infections. This study compares the
outcomes of endoscopic and microscopic type 1 tympanoplasty in terms of air-bone
gap (ABG) improvement, operation time, and graft take-up rate. A randomized
controlled trial (RCT) was conducted with patients undergoing either endoscopic or
microscopic tympanoplasty. Statistical analysis using paired t-tests revealed that
endoscopic tympanoplasty had significantly shorter operation times (p < 0.001) and
marginally better ABG improvement (p = 0.038) compared to microscopic
tympanoplasty. However, the graft take-up rates between the two techniques were not
significantly different (p = 0.29). These findings suggest that endoscopic
tympanoplasty may be a viable alternative to the microscopic approach, offering
advantages in surgical efficiency without compromising graft success.
